A H 2 PRIUS (EM01R0U) HOW TO USE THIS MANUAL B This manual provides information on the electrical circuits installed on vehicles by dividing them into a circuit for each system. The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point. (All circuit diagrams are shown with the switches in the OFF position.) When troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see System Circuit section), the power source supplying power to that circuit (see Power Source section), and the ground points (see Ground Point section). See the System Outline to understand the circuit operation. When the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors and ground points of each system circuit. Internal wiring for each junction block is also provided for better understanding of connection within a junction block. Wiring related to each system is indicated in each system circuit by arrows (from__, to__). When overall connections are required, see the Overall Electrical Wiring Diagram at the end of this manual. 3 PRIUS (EM01R0U) B HOW TO USE THIS MANUAL * The system shown here is an EXAMPLE ONLY.

[M] : Page No. [N] : Indicates the ignition key position(s) when the power is supplied to the fuse(s). 5 PRIUS (EM01R0U) B HOW TO USE THIS MANUAL [O] System Outline Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW. When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows through the rear lights warning light to TERMINAL 4 of the light failure sensor. Stop Light Disconnection Warning When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the disconnection and the warning circuit of the light failure sensor is activated. As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning circuit on and holds the warning light on until the ignition SW is turned off.

start hybrid system by operating power SW and brake pedal simultaneously. It also has function to hold the electrical key in the key slot and not to release the key from it unless the power supply condition and shift range position are met. If there is abnormality in the system, amber portion of power SW blinks to warn the driver. 1. ACC ON Operation When the electrical key turns on half–inserted SW and deep–inserted SW after inserting in the key slot, transponder key computer activates transponder key amplifier incorporated in key slot to identify ID. After the identification, if power SW is pushed without depressing brake pedal, power source control ECU starts. The ECU confirms that the brake pedal is not depressed from signal of stop light SW and also requests ID code box for ID identification result. If the ID identification is normal, power source control ECU turns on ACC relay and changes indicator of power SW to green lighting. In consequence, power supply is set to ACC ON condition. 2. IG ON Operation If power SW is pushed without depressing brake pedal when ACC ON, power source control ECU confirms that the brake pedal is not depressed, and then turns on IG1 relay and IG2 relay as well as change indicator of power SW to amber lighting. Power supply is IG ON condition then. 3. Hybrid Start–Up Operation (READY) When the electrical key turns on half–inserted SW and deep–inserted SW after inserting in the key slot, ID code box activates transponder key amplifier incorporated in key slot to identify ID. After the identification, if power SW is pushed with depressing brake pedal, power source control ECU starts. The ECU confirms that the brake pedal is depressed from signal of stop light SW and also requests ID code box for ID identification result. If the ID identification is normal, the ECU turns on ACC relay, IG1 relay and IG2 relay, and changes indicator of power SW to amber lighting. Power supply is IG ON condition then. After that, power source control ECU sends start–up signal to hybrid vehicle control ECU. Hybrid vehicle control ECU and ID code box make communication for start–up permission. Hybrid vehicle control ECU controls to start–up hybrid system (READY). At starting up hybrid system, power source control ECU controls to light off indicator of power SW. 4. Power Supply Off Operation ∗ When shift range is in P range If power SW is pushed with power supply at READY condition while the vehicle is stationary, power source control ECU confirms that shift range is in P range, and then turns off ACC relay, IG1 relay and IG2 relay to put power supply in OFF condition. The ECU also controls to light off indicator of power SW. If power SW is pushed with power supply at IG ON condition and without depressing brake pedal while the vehicle is stationary, power source control ECU confirms that shift range is in P range, and then turns off ACC relay, IG1 relay and IG2 relay to put power supply in OFF condition. The ECU also controls to light off indicator of power SW. If electrical key is taken off from key slot with power supply at ACC ON condition while the vehicle is stationary, power source control ECU controls to put power supply in OFF condition automatically, which lights off indicator of power SW. ∗ When shift range is in other than P range If power SW is pushed with power supply at IG ON (Including READY) condition while the vehicle is stationary, parking lock operation is carried out. After that, power source control ECU confirms that shift range is in P range and then turns off ACC relay, IG1 relay and IG2 relay to put power supply in OFF condition. The ECU controls to light off indicator of power SW. 5. Key Interlock Operation Power source control ECU controls to hold the electrical key in the key slot and not to release the key from it unless the power supply condition and shift range position are met. Power supply condition and shift range position during the key interlock in operation are as follows; ∗ At starting–up hybrid system ∗ At power supply at IG ON ∗ At power supply at ACC ON and shift range at other than P range 6. Emergency Stop Operation of Hybrid System If power SW is kept pushed more than three seconds during driving, hybrid system stops and power supply is changed to ACC ON. 7. Power Supply Resuming Control Power source control ECU always stores power supply condition (OFF, ACC ON, IG ON) When power supply is resumed after shutting off power supply by disconnecting battery terminal, original power supply condition returns due to control of power source control ECU. 89 PRIUS (EM01R0U) Push Button Start System and Hybrid Vehicle Immobiliser System : Parts Location Code See Page A8 Code See Page Code See Page 48 J3 47 48 J6 48 J9 C7 46 J10 C10 49 J12 A 50 S7 A 51 D1 49 J13 B 50 S8 B 51 D7 52 J14 50 S9 C 51 S10 D 51 A12 B5 A M13 50 50 P6 51 50 P11 51 50 S1 47 E4 A 49 J15 50 E6 C 49 J16 50 S11 51 E7 D 49 J17 50 S16 51 49 J18 50 T4 51 G1 H14 A 49 J24 50 T5 51 H15 B 49 J25 50 T11 51 H16 C 49 K2 A 50 H17 D 49 K3 B 50 : Relay Blocks Code 3 See Page 22 Relay Blocks (Relay Block Location) Engine Room R/B (Engine Compartment Left) 90 PRIUS (EM01R0U) : Junction Block and Wire Harness Connector Code 1A 1B 1D See Page Junction Block and Wire Harness (Connector Location) 30 Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) 30 Floor Wire and Driver Side J/B (Lower Finish Panel) 1E 1F 1G 30 1J Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 1K 1L 31 1M 3C 3D 3I 3J 23 Engine Room Main Wire and Engine Room J/B (Engine Compartment Left) 24 4C 4D 4E 4F 4G 4H 38 Instrument Panel Wire and Center Connector No.1 (Behind the Combination Meter) 42 Instrument Panel Wire and Center Connector No.2 (Instrument Panel Brace RH) 4I 4J 4K 4L 5C 5D 5E 5F 5G 5H 5I 5J 5K 5L 5M : Connector Joining Wire Harness and Wire Harness Code EB1 IA1 IA3 IG1 IG2 II1 See Page Joining Wire Harness and Wire Harness (Connector Location) 56 Engine Wire and Engine Room Main Wire (Inside of the Engine Room R/B) 58 Engine Room Main Wire and Instrument Panel Wire (Upper Parts of Front Body Pillar LH) 59 Instrument Panel Wire and Instrument Panel No.2 Wire (Behind the Combination Meter) 59 Engine Wire and Instrument Panel Wire (Behind the Glove Box) : Ground Points Code EC See Page Ground Points Location 56 Engine Block 56 Left Side of the Suspension Tower IH 58 Cowl Side Panel LH II 58 Instrument Panel Brace LH EE EF 91 PRIUS (EM01R0U) TOYOTA Hybrid System H14(A), H15(B), H16(C), H17(D) Hybrid Vehicle Control ECU NODD 24 C VLO MREL 31 C 4 C W O L 20A HEV 15A AM2 (BAT) 1 3E 2 L 1 3C V L 1 3D W W (BAT) 1 B 4 A 5 A AMD NODD VLO 2 ID1 2 A IGCT Relay 1 3J 4 3J 2 3J O IGCT 1 A L S 3 A Y 1 C 5(A), C 6(B) Converter 40A HTR 2 3 3J 1 3I 1 R B 5 IA2 1 3M 4 5H W W–B 100A DC/DC L V 2 4 IA1 W 10 1A W V B 1 A 2 B 1 1G INV W/P Relay 6 5J 11 1A 17 1E 5A DC/DC–S 3 4K 3 4I 1 4J 5 4J W 4 IN1 V W 1 BE1 B V W–B B B V W–B F15(A), F16(B) Fusible Link Block W3 Water Pump Motor (Inverter) 120A MAIN 2 W M V 1 Y L L W–B EE W–B 1 B 1 A W–B S27(A), S28(B) Short Connector (Water Pump) 92 PRIUS (EM01R0U) W–B Battery IH H14(A), H15(B), H16(C), H17(D) Hybrid Vehicle Control ECU W W L GR GR V (BAT) P 7 5D 11 5D 13 1A R 13 IG2 9 IG2 B 13 5J 8 5J 10 5J B GR B 3 B 11 B 7 B MPX+ MPX2+ V G 3 4 GND VO S5 14 25 24 B R 2 THR BEAN IC GR S5RM 10 A Buzzer BR RH 9 A 1 B J6 Junction Connector Power Supply Circuit A9 A/C Room Temp.

Motor Generator Condition (1) Supply of electrical power from the HV battery to motor generator no.2 provides force to drive the wheels. (2) While the tires are driven by the engine via the planetary gears, motor generator no.1 activates to supply electricity via the planetary gears to motor generator no.2 to drive the wheels. (3) When the vehicle is decelerating, kinetic energy from the wheels is recovered into electrical energy and used to recharge the HV battery by motor generator no.2. The hybrid vehicle control ECU switches between these modes (1, 2, 1+2, or 3) according to the driving conditions. However, when the state of charge of the HV battery is low, the HV battery is charged by the engine turning motor generator no.1. 2. Inverter ∗ The inverter converts high–voltage direct current of HV battery to three–phase alternating current for driving motor generator no.1 and motor generator no.2. ∗ The activation of the power transistors is controlled by the HV ECU. In addition, the inverter transmits necessary information for current control, such as the output amperage or voltage, to the HV ECU. ∗ Along with motor generator no.1 and motor generator no.2, the inverter is cooled by the exclusive radiator of the coolant system that is separated from that of the engine. ∗ In vehicle collision, circuit breaker sensor installed in the inverter outputs collision signal to stop the system. ∗ Boost converter has been adopted in the inverter, which increases rated voltage output from HV battery of DC 201.6V to DC 500V. After increasing voltage, the inverter converts direct current to alternating current. 3. Converter The power source for auxiliary equipment of the vehicle such as the lights, audio system, and the air conditioning system, as well as the ECUs, is based on a rated voltage of DC 12V system. Because the generator outputs at DC 201.6V, the converter is used to transform the voltage from rated voltage of DC 201.6V to DC 12V in order to recharge the auxiliary battery. The converter is installed on the underside of the inverter. 4. HV Battery ∗ In Prius, the sealed nickel hydride (Ni–MH) battery has been adopted. This HV battery has high power density, lightweight and longevity to match characteristics of TOYOTA hybrid system. Because TOYOTA hybrid system controls charge/discharge to maintain charge/discharge control to maintain SOC (State of charge) at constant level while the vehicle is operating normally, it does not have to rely on the use of external recharges. ∗ The HV battery, battery ECU, system main relay and the cooling fan are put in a signal case which is placed in the luggage compartment behind the rear seat to make more effective use of vehicle space. ∗ A service plug that shuts off circuit is provided in the middle of the 28 modules (Rated battery capacity = 201.6V). Before servicing any portion of the high–voltage circuits, make sure to remove the service plug. Please do not READY ON when you remove the service plug. There is a possibility that battery ECU breaks down. ∗ To ensure the HV battery’s performance, the battery ECU controls the operation of the cooling fan to avoid the heat that is generated in the HV battery during charging and discharging. 5. Regenerative System Operation This system operates the motor as a generator to change the kinetic energy of the vehicle into the electricity when accel pedal is released or foot braking decelerates

Input Signals (1) Engine coolant temp. signal circuit The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance which varies according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the engine control module as a control signal. (2) Intake air temp. signal circuit The intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input to TERMINAL THA of the engine control module as a control signal. (3) Oxygen sensor signal circuit The oxygen density in the exhaust emission is detected and is input from the heated oxygen sensors to TERMINAL OX1B of the engine control module as a control signal. (4) RPM signal circuit The camshaft position is detected by the camshaft position sensor, and is input into TERMINAL G2 of the engine control module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal is input into TERMINAL NE+ of the engine control module. (5) Throttle position sensor signal circuit The throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALS VTA and VTA2 of the engine control module. (6) Vehicle speed signal circuit ABS speed sensor detects vehicle speed and the speed signal is input from skid control ECU to engine control module. (7) Battery signal circuit Voltage is constantly applied to TERMINAL BATT of the engine control module. When the power SW is pushed on, the voltage for engine control module starts up power supply which is applied through the EFI M relay, to TERMINAL +B of the engine control module. The current from the IGN fuse flows to TERMINAL IGSW of the engine control module, and voltage is constantly applied to TERMINAL +BM. (8) Intake air volume signal circuit The intake air volume is detected by the mass air flow meter, and is input to TERMINAL VG of the engine control module as a control signal. (9) Water temp. (CHS) signal circuit The water temp. (CHS) sensor detects the water temp. (CHS) and has a built–in thermistor with a resistance which varies according to the water temp. (CHS). The water temp. (CHS) is input into TERMINAL THW2 of the engine control module as a control signal. (10) Engine knock signal circuit Engine knocking is detected by the knock sensor, and is input into TERMINAL KNK1 of the engine control module as a control signal. (11) Air fuel ratio signal circuit The air fuel ratio is detected and input into TERMINAL A1A+ of the engine control module as a control signal. 138 PRIUS (EM01R0U) 2. Control System ∗ SFI system The SFI system monitors the engine condition through the signals input from each sensors to the engine control module. The control signal is sent to the engine control module TERMINALS #10, #20, #30 and #40 to operate the injector (Fuel injection). The SFI system controls the fuel injection with the engine control module according to the driving conditions. ∗ ESA system The ESA system monitors the engine condition through the signals input from each sensors to the engine control module. The best ignition timing is decided according to this data and the data stored in the engine control module. The control signal is output to TERMINALS IGT1, IGT2, IGT3 and IGT4, and these signals control the igniter to provide the best ignition timing. ∗ Heater control system of heated oxygen sensor The heater control system of heated oxygen sensor turns the heater on when the intake air volume is low (Temp. of exhaust emission is low), and warms up the heated oxygen sensors to improve their detecting performance. The engine control module evaluates the signals from each sensors, and outputs current to TERMINAL HT1B to control the heater. ∗ Heater control system of air fuel ratio sensor The heater control system of air fuel ratio sensor turns the heater on when the intake air volume is low (Temp. of exhaust emission is low), and warms up the air fuel ratio sensor to improve detecting performance of the sensor. The engine control module evaluates the signals from each sensor, current is output to TERMINAL HA1A, controlling the heater. ∗ Fuel pump control system The engine control module supplies current to TERMINAL FC, and controls the operation of the fuel pump with the C/OPN relay. ∗ VVT–i VVT–i controls the intake camshaft to optimal valve timing in accordance with the engine condition. ∗ CHS system Engine control module controls CHS W/P relay to run electric pump to supply heated water stored in CHS tank to engine head. The electric pump stops when the water reaches certain temperature or certain time goes by. Warming engine head optimizes combustion conditions at engine start to reduce emission of incomplete combustion gas. 3. Diagnosis System When there is malfunction in the engine control module signal system, the malfunctioning system is recorded in the memory. The system can be found by reading the code displayed on the malfunction indicator lamp. 4. Fail–Safe System When malfunction has occurred in any system, there is possibility of engine trouble due to continuous control based on that system. In such a case, the fail–safe system either controls the system using the data (Standard values) recorded in the engine control module memory, or stops the engine. 139 PRIUS (EM01R0U) Engine Control :

Interior light operates with control of body ECU. Illumination Control Lighting function of interior light, overhead J/B, electrical key holder When any door is opened, signal is sent from door courtesy SW to body ECU. Interior light, overhead J/B and key slot light on gradually from unlit condition to fully lit condition within 1.5 seconds if lighting SW of interior light and overhead J/B is set for door. After that, when all the doors are shut and any one of the door is unlocked, interior light, overhead J/B and key slot are lit up for about 15 seconds (Timer lighting) and then are lit off gradually. Under conditions that power SW is set at OFF position and all the doors are closed, when any one of the door is unlocked, interior light, overhead J/B and key slot light on gradually from unlit condition to fully lit condition within 1.5 seconds, stay on for the certain time (Timer lighting) and then light off gradually. If power SW is turned from OFF position to ACC ON or IG ON position during timer lighting, the timer lighting function is cut off immediately and the light goes off gradually. Even though timer lighting conditions are satisfied when power SW is at ACC ON or IG ON position, the light does not stay on for certain time (For 15 sec.) after lighting, but goes off gradually. All the doors are locked during timer lighting, the timer lighting function is cut off immediately and the light goes off gradually. : Parts Location Code See Page A8 Code See Page 48 D15 52 Code See

18 B B 8 T4 Transmission Control ECU W–B W A System Outline Smart key system is a system to enable, without operating the key, to lock/unlock doors, to unlatch luggage compartment door, to start engine (Motor). It owes interactive communication function of electrical key, which makes the vehicle to recognize where the key is. All that driver has to do is to have the key with him or her. If the electrical key runs out of dry battery, the key operates as normal key without the smart key system. 1. Smart Door Unlock Function When all the doors are locked, oscillator of each door sends signal regularly and forms detecting area outside of passenger room around 0.7 to 1m from each door handle. After forming the area, driver goes in the area with the electrical key, the key sends ID code signal. Certification ECU receives the signal through electrical key antenna and identifies ID code. After identifying ID code, doors in the area get into unlock stand–by condition. At this time, sensors installed in door handles activate. Touching back of door handles unlocks the door locks, lights up hazard lamp and sounds wireless door lock buzzer. If any door is not opened within 30 seconds after unlocking the door lock, the doors lock again. 2. Smart Door Lock Function If driver gets off the vehicle with the electrical key and pushes lock SW of door handles when all doors are locked, certification ECU sends signal to inside and outside of passenger room to identify the electrical key. In case identification with inside of the passenger room is NG and that with outside of it is OK, doors lock. Door ajar alarm sounds to tell a door is not shut properly when lock SW of door handle is pushed with any door opened. 3. Smart Luggage Compartment Door Unlatch Function If the driver stands in front of luggage compartment door with the electrical key and pushes unlock SW of luggage compartment door, ID code of the electrical key is identified with certification ECU through luggage oscillator (Outer). After the ID code is identified, luggage compartment door is unlocked. To keep pushing luggage compartment door opener SW unlatches luggage compartment door. 4. Smart Ignition (READY) Function When the driver pushes the power SW with the electrical key with him or her, ID code of the electrical key is identified with certification ECU by room oscillator in passenger room. After the ID code is identified, hybrid vehicle immobiliser is released and electric power is set at ACC ON to enable to start engine. Then pushing the power SW sets power supply at IG ON and another pushing sets it at OFF. Condition circulates from ACC ON to/from IG ON to/from OFF and to ACC ON. The vehicle gets READY to drive when the driver pushes power SW with applying brake pedal at any power supply condition. 5. Smart Alarm Function ∗ If any door is opened and then shut with shift at P range and the power SW at other than OFF position, certification ECU identifies ID code with inside of passenger room twice. In case the identification result is NG, buzzer in combination meter alarms (Once) and wireless door lock buzzer alarms (Three times), and smart warning light in combination meter lights up. If power supply is pushed OFF with power SW or identification of the electrical key with inside of passenger room is confirmed at the second time, the warning stops. ∗ If all the doors are closed with shift at P range and power SW at other than OFF position, pushing lock SW of door handle starts certification ECU to identify ID code with inside and outside of passenger room. In case result of identification with inside is NG and that with outside is confirmed, wireless door lock buzzer alarms (For two seconds) and doors do not lock. ∗ If driver’s side door is opened and then shut with shift at other than P range and power SW at other than OFF position, certification ECU identifies ID code with inside of passenger room twice. In case the identification result is NG, buzzer in combination meter and wireless door lock buzzer alarm continuously as well as smart warning light in combination meter lights up. Then, if shift is put into P range or the identification with inside is confirmed at the second time, the continuos alarming stops. If the driver turns electric power OFF with power SW or the identification with inside is confirmed at the second time, smart warning light goes off. ∗ If other doors than driver’s side door is opened and then shut with shift at other than P range and power SW at other than OFF position, certification ECU identifies ID code with inside of passenger room twice. In case the identification result is NG, buzzer in combination meter alarms (Once) and wireless door lock buzzer alarms (Three times), and smart warning light in combination meter lights up. If power supply is pushed OFF with power SW or identification with inside of passenger room is confirmed at the second time, the warning stops. ∗ If lock SW of door handle is pushed with all the doors shut and power SW at OFF position, certification ECU identifies ID code with inside of passenger room twice. In case the identification is confirmed then, wireless door lock buzzer alarms (For two seconds) but doors do not lock. ∗ If power supply is turned OFF with power SW after ”READY to drive” condition are kept for about 20 minutes, certification ECU identifies ID code of the electrical key with inside of passenger room. In case the ECU recognizes code of battery voltage decrease, buzzer in combination meter alarms once. ∗ If power SW is pushed ON, certification ECU identifies ID code with inside of passenger room twice. In case the identification result is NG, buzzer in combination meter alarms once and smart warning light lights up for about five seconds. Then, driver’s operation of power SW is cancelled. 219 PRIUS (EM01R0U) Smart Key System and Wireless Door Lock Control 6. Smart Door Unlock Mode Change Function If lock button and PANIC button of electrical key are pushed simultaneously for about five seconds with power SW at off position and electrical key not in key holder, smart door unlock mode changes to all door unlock mode or to each door unlock mode (At front passenger door, it changes only to all door unlock condition). The unlock modes circulate. Wireless door lock buzzer and buzzer in combination meter sound to inform mode change. 7. Power Saving Function for Battery In case the electrical key does not send signal for five days or longer, interval between identification time is extended from about 300 ms to 600 ms. In case the electrical key does not send signal for 14 days or longer, or the key is in detected area outside of vehicle for ten minutes or longer, smart function stops its operation. Smart function resumes under following conditions. ∗ When lock and unlock signal of wireless function of the key is input and its ID code is identified. ∗ When doors are locked with lock SW ON. ∗ When doors are locked or unlocked with door key SW operation. 8. Manual Operation Function Electrical key has lock, unlock, and PANIC buttons. It can operate wireless door locking manually. Its operation is the same as one without smart key system. 9. Smart Illumination Function When driver goes in detected area outside of passenger room with electrical key with him or her and its ID code is identified, interior light, overhead J/B and key slot light up for about 15 seconds by timer. 10. Smart Entry System Cancelled Smart key system is cancelled under following conditions. ∗ When smart key system cancel SW is turned on. ∗ When electrical key is inserted in key slot. ∗ When battery of electrical key is dead. : Parts Location Code See Page A8 Code See Page Code H14 A 49 A 48 H17 D 49 L3 53 B6 B 48 I18 53 L4 53 B7 C 48 J6 50 L6 53 B5 K3 See Page 48 B 50 C7 46 J7 A 50 L7 53 C10 49 J8

Shift Control System System Outline Under this system, operating signal of shift lever is sent to hybrid vehicle control ECU to control hybrid motor, which changes shift ranges (R, N, D, B) electrically. When shift is put in P range, transmission control ECU receives operating signal from hybrid vehicle control ECU and activates parking lock electrically. 1. Shift Range Change Function Gear can be shifted to any shift range under condition when vehicle can drive except when reject function is in operation. When vehicle cannot drive with power SW at IG ON position, gear can be shifted only to P and N range. When vehicle cannot drive with power SW at ACC ON position, gear can be shifted only to P range. When power SW is at OFF position, gear cannot be shifted to any range. When main SW is operated at vehicle stop after starting hybrid system, gear is automatically changed to P range from any other gear range and turns off power supply. 2. Reject Function Changing gear may not effect to change range under certain vehicle condition. Under such condition, warning buzzer of combination meter sounds to show the rejection and call for driver’s attention. Followings are shift operations and shift range conditions under which reject function is activated. ∗ When gear is shifted from P range to other range without applying brake pedal, gear stays in P range. ∗ Main SW cannot put gear in P range during driving but changes to N range. ∗ Shift change to forward or backward during driving changes gear to N range. ∗ When gear is changed from other range than D range to B range, gear is changed to N range automatically. 3. Combination Meter Indication The combination meter shows present shift range position. Other shift range positions than D or B range are not shown in lighting in the combination meter. This is to avoid unnecessary shifting operation to B range from other shift position except D range. 4. Operation of Parking Lock Operation signal from/to P range is sent from main SW or power SW to transmission control ECU through hybrid vehicle control ECU. At that time the transmission control ECU operates P CON MTR relay, activates parking lock actuator with appropriate control of electric current, and lights up main SW when shift is at P range. If the system has abnormality on parking lock operation, it tells the system abnormality to the driver by lighting up master warning light on combination meter, displaying warning of the system abnormality on the multi–display, and blinking indicator light of main SW. 5. Operation at Electric Power OFF Under electric power OFF, transmission control ECU receives signal from power source control ECU by multi–communication, and sends shift range position information to hybrid vehicle control ECU. The hybrid vehicle control ECU sends signal to power source control ECU to tell whether it is right or wrong condition to turn off electric power. Accepted conditions for electric power OFF are as follows; ∗ When hybrid vehicle control ECU is not sending request signal for parking lock release with shift range in P range position. ∗ With shift range is at other range than P range, when hybrid vehicle control ECU is outputting signal that hybrid system is not running or request signal for parking lock. ∗ When there is abnormal motor’s not running condition with paring lock in operation, and hybrid system is not running and parking brake is being applied. : Parts Location Code See Page A8 B5 48 A Code J13 See Page B Code See Page 50 P6

9(D), M10(E) Motor Generator No. 2 W–B 8 EB1 EF 269 PRIUS (EM01R0U) Cruise Control System Outline Cruise control is the speed control device, which can set desired speed by just operating the switch on the control panel without applying the accelerator pedal. The device can be used when driver would like to drive the vehicle at fixed speed. 1. Set Control If the cruise control switch is pushed to – SET side and hand is released from the switch during driving, (The available range of set speed: between 40 and 200 km/h) with the ON–OFF switch at ON (Power indicator comes on), the device stores vehicle speed at that time and controls it constantly at the set speed. 2. Set Speed Control The device compares the actual vehicle speed with the set speed, and controls the driving power of the motor and the engine by calculating the cruise control requirements to drive it constantly at the set speed. 3. Coast Control If the cruise control switch is kept pushed to the – SET side during driving in the cruise control mode, the device recognizes the cruise control requirement is at zero and decelerates the vehicle speed. When hand is released from the cruise control switch, the device stores the vehicle speed while the vehicle speed is decelerating. From then on, vehicle speed is controlled to stay at that speed. Every time the switch is operated to – SET side momentarily (For about 0.5 seconds), the set speed is decreased by about 1.6 km/h. However, in case of tap–down operation to make more than 5 km/h gap between the set speed and the actual vehicle speed, the device recalls the original set speed and controls it at the speed constantly. 4. Accel Control If the cruise control switch is kept pushed to the + RES side during driving in the cruise control mode, the device recognizes the cruise control is on the acceleration side and accelerates the vehicle speed. When hand is released from the cruise control switch, the device stores the vehicle speed at that time and controls it with the set speed constantly. Every time the switch is operated to + RES side momentarily (For about 0.5 seconds), the set speed is increased by about 1.6 km/h. However, in case of tap–up operation to make more than 5 km/h gap between the set speed and the actual vehicle speed, the device does not change the set speed. (Tap–up operation is not available.) 5. Resume Control After the cruise control mode is cancelled by any one the cancel switches, the mode can be resumed and controlled at the set speed by operating the cruise control switch in the + RES direction providing that the vehicle speed has not dropped below the low speed limit [Approx. 40 km/h (25 mph)]. The mode cannot be resumed if the vehicle speed once drops below the low speed limit, because the speed in the memory is cleared. 6. Manual Cancel Control If any of the following signals is sent to the device while the vehicle is running in the cruise control, the cruise control is cancelled accordingly. ∗ Stop light switch: ON (Depressing the brake pedal) ∗ CANCEL switch of control switch: ON ∗ ON–OFF switch: OFF 7. Auto Cancel Function A) The set speed is cleared and the cruise control is canceled under the following conditions. The cruise main indicator blinks until the main switch is turned OFF. The speed control is unavailable unless the main switch is turned ON again. ∗ When the stop light switch open or short–circuits. ∗ When signal of sudden change in the vehicle speed is sent. B) The set speed is cleared and the cruise control is canceled under the following conditions. ∗ When there is malfunction of the stop light switch input circuit. ∗ When the vehicle speed becomes lower than 40 km/h. ∗ When the vehicle speed becomes lower than the speed that 16 km/h is subtracted from the set speed. 270 PRIUS (EM01R0U) : Parts Location Code See Page A8 B5 A Code See Page 48 J1 47 Code M10 See Page E 48 J3 47 C2 46 J6 50 S4 A 51 C10 49 J9 50 S5 B 51 C12 49 J12 A 50 S7 A 51 D1 49 J13 B 50 S8 B 51 C 51 D 51 E4 P6 47 51 A 49 J14 50 S9 E5 B 49 J15 50 S10 E6 C 49 J16 50 S11 51 E7 D 49 J17 50 S16 51 49 J18 50 T2 47 G1 H14 A 49 J24 50 T3 47 H15 B 49 J25 50 T4 51 H16 C 49 M5 47 T5 51 H17 D 49 47 T11 51 M9 D : Relay Blocks Code 3 See Page 22 Relay Blocks (Relay Block Location) Engine Room R/B (Engine Compartment Left) : Junction Block and Wire Harness Connector Code 1A 1F 1G 1L 1M 3I 3J See Page 30 Junction Block and Wire Harness (Connector Location) Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) 30 Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 31 24 Engine Room Main Wire and Engine Room J/B (Engine Compartment Left) 38 Instrument Panel Wire and Center Connector No.1 (Behind the Combination Meter) 42 Instrument Panel Wire and Center Connector No.2 (Instrument Panel Brace RH) 4C 4D 4E 4F 4G 4H 4I 4K 4L 5B 5C 5D 5F 5G 5H 5J 5K 5L 5M 271 PRIUS (EM01R0U) Cruise Control : Connector Joining Wire Harness and Wire Harness Code EB1 IA1 IA3 IG1 IG2 II1 See Page Joining Wire Harness and Wire Harness (Connector Location) 56 Engine Wire and Engine Room Main Wire (Inside of the Engine Room R/B) 58 Engine Room Main Wire and Instrument Panel Wire (Upper Parts of Front Body Pillar LH) 59 Instrument Panel Wire and Instrument Panel No.2 Wire (Behind the Combination Meter) 59 Engine Wire and Instrument Panel Wire (Behind the Glove Box) : Ground Points Code EC See Page Ground Points Location 56 Engine Block 56 Left Side of the Suspension Tower IH 58 Cowl Side Panel LH II 58 Instrument Panel Brace LH ED EE EF 272 PRIUS (EM01R0U) Memo 273 PRIUS (EM01R0U) EPS (IG) (BAT) 10A GAUGE (IG) (BAT) 50A EPS 7. 5A ECU–IG 15A DOME 2 1 1M 2 3 S 7(A), S 8(B), S 9(C), S10(D) Skid Control ECU 2 3C FL– FR+ FR– RL+ RL– RR+ RR– 22 D 32 A 22 A 35 B 27 B 31 C 23 C V G P L W B W B R B FL+ 28 D R J6 Junction Connector O B W R 7 1L 13 1A ABS Speed Sensors 15 5H P 8 1L 7 5D 11 5D 13 IG2 9 IG2 9 5C P 9(D) Power Steering Motor V Y B L 16 5H Y 16 5L 22 21 C10 Combination Meter B R W W B Master W Power Supply Circuit (VFD) 6 B 1 A 1 D 2 D 7 B 1 B 2 B IG PIG M1 M2 CANL CANH SIL V GR B 4 IG1 10 IG1 TRQV TRQ2 TRQG 6 C 7 C 8 C G Y W–B TRQ1 5 C W 24 PGND 2 A R 25 14 Buzzer Y 9 BR BEAN IC B P 7(A), P 8(B), P 9(D), P10(C) Power Steering ECU 4 4C 9 4C P10(C) Power Steering Torque Sensor B 15 4H GR 16 4I V BR V II IG 274 PRIUS (EM01R0U) (BAT) (IG) 7. 5A STOP S 7(A), S 8(B), S 9(C), S10(D) Skid Control ECU 18 1A B O 27 1A 14 B R 11 IA1 J9 Junction Connector 12 IA1 2 3 1 4 A C C (Shielded) B W (Shielded) (Shielded) A G 19 B J17 Junction Connector A S16 Stop Light SW 18 B L 13 IA1 CAN–H B (Shielded) B A W B (Shielded) W B W 14 6 CANL CANH SIL B W–B B W A D1 Data Link Connector 3 B B A W B (Shielded) A W G J15 Junction Connector B V 22 B STP CAN–L W SP1 7. 5A IGN 7 11 5C W A A A A 8 5M W A J16 Junction Connector A A 7 IA3 W–B V W–B A J25 Junction Connector J24 Junction Connector A B GR GR V W–B B W–B IH 275 PRIUS (EM01R0U) EPS ∗ 1 : w/ Smart Key System ∗ 2 : w/o Smart Key System B A B A B B J18 Junction Connector W CA1H 17 W CA1L 18 (Shielded) G1 Gateway ECU 2 B 8 A 9 A ST1– CANH CANL (Shielded) W A B G B H14(A), H15(B) Hybrid Vehicle Control ECU W VCK4 VSX3 VCX3 VSX2 21 A 24 A E2X2 VCX2 VSX1 E2X1 VCX1 G B R W 17 A Y 15 A L 25 A W 16 A BR 14 A P 23 A SB 31 A 8 A 6 A 5 A 3 A 4 B 5 B 6 B 1 B 2 B 3 B VSX4 VCX4 VSX3 VCX3 VSX2 E2X2 VCX2 VSX1 E2X1 VCX1 W–B VSK4 30 A (Shielded) B 14 4E S 4(A), S 5(B) Shift Lever Position Sensor W–B 4 4H A B B GR W–B GR J25 Junction Connector A IH 276 PRIUS (EM01R0U) G1 Gateway ECU MPD2 MPD1 GTX+ GTX– 12 3 6 21 GR B W 4 5C 8 5C 6 5C 7 5C 13 5J 8 5G 6 5E 7 5E B W 8 GR GR II1 24 MPX2 II1 14 4I GR 2 4D 8 5J 13 5G 8 5K 13 5D B 7 GR MPX1 11 GR (∗1) MPX2+ P6 Power Source Control ECU 9 32 B B MPX2 3 MPX+ A8 A/C Control Assembly W (∗2) MPX1 18 B 31 MPX2 S11 Certification ECU GR (∗1) MPX1 T4 Transmission Control ECU 19 7 4L B GR 7 4I 5 TX1– W 14 4K 4 TX1+ M13 Multi–Display 16 4L GR P T5 ID Code Box 9 1G 3 IG2 17 11 4D W 2 4C MPX1 17 MPX1 GR 13 4K MPX2 B 5(A) Body ECU B 12 16 B MPX2 T11 Tire Pressure Warning ECU 6 MPX1 MPX2 15 A 2 IG1 B 11 4F B B GR 277 PRIUS (EM01R0U) EPS System Outline This is a system to assist the driver to steer the vehicle with easy steering force.

ABS Operation If the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of all the four wheel cylinders to automatically avoid wheel locking and to ensure the directional and steering stability of the vehicle. Under the situation, the skid control ECU controls the solenoids in the actuators, using the signals from the sensors to move the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If the skid control ECU detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the solenoids in the actuators to increase the braking pressure. 2. Electronic Brake–Force Distribution Skid control ECU distributes appropriate brake–force to front and rear wheels (Control of brake–force distribution to front and rear wheels) corresponding to the vehicle driving conditions. It also makes effective use of rear wheel brake–force to match loading condition and decelerating of the vehicle, resulting to reduce depressing of brake pedal and to ensure effective braking. In braking during making a turn, the ECU controls appropriate brake–force distribution to right and left wheels (Control of brake–force distribution to right and left wheels) to ensure stability and braking of the vehicle. 3. Brake Assist System Skid control ECU recognizes emergency braking from detecting applying speed of brake pedal and brake travel, and controls braking effectiveness to supply strong brake–force for the emergency braking. 4. VSC Operation (w/ VSC) Unexpected road conditions, emergency situation, and any other external factors may cause large under– or over–steering of the vehicle. If they occur, the VSC system automatically controls the driving power and wheel brakes to reduce the under– or over–steering. To reduce large over–steering : If the VSC system determines that the over–steering is large, it activates the brakes for the outer turning wheels depending on the degree of the over–steering to produce the moment toward the outside of the vehicle and reduce the over–steering. To reduce large under–steering : If the VSC system determines that the under–steering is large, it controls the driving power and activates the front wheel brakes and rear inner side wheel brake to reduce the under–steering. If there is malfunction in the VSC system, the VSC indicator lights up to warn the driver. 5. Mutual System Control Due to cooperative control with hybrid vehicle control ECU, skid control ECU controls hydraulic brake to collect much electrical energy by making the most use of regenerative brake. Skid control ECU also improves stability of the vehicle, performing cooperative control with power steering ECU to give steering torque assistance, corresponding to driving conditions. (w/ VSC) 6. Electric Source Backup Function Electric charge is stored in brake control power supply. If voltage of vehicle electricity is declined, electric charge is released to cover electric supply to the system. 7. Fail Safe Function Skid control ECU monitors the system component parts electrically. In case there is abnormality in ECU, sensor signal and actuator, normal parts except parts with abnormality continue braking operation. Even in case braking is shut off due to malfunction of oil pressure source, braking is secured as master cylinder pressure made by manpower works on wheel cylinder. In case only regenerative brake is not effective due to abnormality in communication with hybrid vehicle control ECU, control will be changed to have oil pressure brake generate all the braking force

in accordance with the following precautionary instructions and the procedure, and precautions in the Repair Manual applicable for the model year. D Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery. D Work must be started more than 90 seconds after the power SW is pushed to the ”OFF” position and the negative (–) terminal cable is disconnected from the battery. (The SRS is equipped with a back–up power source so that if work is started within 90 seconds from disconnecting the negative (–) terminal cable of the battery, the SRS may deploy.) D When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be cleared. So before starting work, make a record of the contents in the audio memory system. When work is finished, reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, power telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function. However, it is not possible to make a record of these memory contents. So when the work is finished, it will be necessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoid erasing the memory in each system, never use a back–up power supply from outside the vehicle. D Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair. D Do not expose the following parts directly to hot air or flame; D Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected; D Never use SRS parts from another vehicle. When replacing parts, replace with new parts. D For the purpose of reuse, never disassemble and repair the following parts. D If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector, replace with new one. D Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system. D Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice. D After work on the SRS is completed, check the SRS warning light. D If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair Manual. ∗ Steering wheel pad ∗ Front passenger airbag assembly ∗ Side airbag assembly ∗ Curtain shield airbag assembly ∗ Seat belt pretensioner ∗ Center airbag sensor assembly ∗ Front airbag sensor assembly ∗ Side airbag sensor assembly ∗ Rear airbag sensor assembly 299 PRIUS (EM01R0U) SRS 1 A 2 A 8 C 7 C SFD+ SFD– SFP+ SFP– VUPL ESR VUPR 2 1 2 W Y 2 BG1 Y–B 1 BG1 Y 2 BC1 Y–B 1 BC1 ESL 1 B 1 W SFR– 2 S19 Side Airbag Sensor RH B SFR+ 1 Y SFL– 2 Y–B SFL+ S18 Side Airbag Sensor LH Y S21 Side Airbag Squib RH Y–B S20 Side Airbag Squib LH 21 A 19 A 20 C 22 C ESD VUPD ESP D2+ 8 B Y 4 IH1 1 A 2 A 1 B 2 B 1 2 3 4 P+ P– P2+ P2– D+ D– D2– D2+ Y–R Y–G 3 IH1 Y 2 IH1 Y–G 1 IH1 Y–R D2– 7 B Y–G D– 6 B Y–B D+ 5 B Y–G P2– 2 B Y–R P2+ 1 B Y P– 3 B Y–B P+ 4 B Spiral Cable A20(A), A21(B) Airbag Squib (Front Passenger Airbag Assembly) A22 Airbag Squib (Steering Wheel Pad) 300 PRIUS (EM01R0U) VUPP A17(A), A18(B), A19(C) Airbag Sensor Assembly F11 Front Passenger Seat Belt Warning Light B A B B C B 22 A 20 A 19 C 21 C 4 A 3 A 5 C 6 C 17 B 23 B ESCD VUCD ESCP VUCP ICD+ ICD– ICP+ ICP– P–AB J20(A), J21(B) Junction Connector B A A B 2 B IGR– 1 Y–B IGR+ 2 Y IGL– 1 Y–B IGL+ Y 2 W VUCR 1 21 IG2 B ESCR 2 10 IG2 W VUCL 1 1 B ESCL C18 Curtain Shield Airbag Squib RH B C17 Curtain Shield Airbag Squib LH L C16 Curtain Shield Airbag Sensor RH PAON 5 B C15 Curtain Shield Airbag Sensor LH P–AB PAON –SL +SL –SR +SR E1 E2 28 B 30 B 27 B 29 B 25 B 26 B Y Y–B Y IJ2 1 1 2 1 2 1 2 1 2 L+ L– R+ R– –SL +SL –SR +SR P23 Pretensioner RH F1 Front Airbag Sensor LH 30 1E 17 1E F2 Front Airbag Sensor RH W–B P22 Pretensioner LH 14 1E IJ2 W 2 B IJ2 W 3 B B IJ2 B 4 W–B PP– 3 C W–B PP+ 4 C W PD– 6 A W PD+ 5 A Y–B A17(A), A18(B), A19(C) Airbag Sensor Assembly IH 301 PRIUS (EM01R0U) SRS (IG) 7. 5A IGN 16 1E S17 Seat Position Airbag Sensor Seat Position Airbag Sensor VS GND Buckle SW O6 Occupant Classification Sensor Front LH 4 Y–B B 17 A 21 B DSP+ IG2 DSP– 24 C FSP– 16 C FSP+ A17(A), A18(B), A19(C) Airbag Sensor Assembly GSW2 15 1E 13 1E 31 1E 32 1E PBEW 13 B R R LA 14 B W SIL 16 B G TC 15 B B 22 B 8 A 4 A FSP+ FSP– 3 11 B 7 B 1 B SIG1 SGD1 SVC1 DIA BSW BGND 2 A 9 A 5 A R G 9 A DBE+ SGD1 2 G R 10 A DBE– SIG1 1 W Y 18 A O 4(A), O 5(B) Occupant Classification ECU V Y SVC1 G 2 SB 1 R 3 2 1 12 IM1 3 1E 8 1E 3 1L 10 1G 14 1L LG W Y 5 5K 11 5H 13 5M 9 5L A B 7 11 TC SIL A/B C A D1 Data Link Connector 3 13 H14 Hybrid Vehicle Control ECU 20 ABFS Y 9 5M W 8 5M P 7 5M L 2 5F J20(A), J21(B) Junction Connector P 14 5L W L W 302 PRIUS (EM01R0U) B16 Buckle SW Front RH R W (IG) (BAT) (BAT) 7. 5A ECU–IG 15A ECU–B (IG) 10A GAUGE 15A DOME 2 7 1L 1 1M 3 V R O 5 1K P B 9 5E J6 Junction Connector 15 5H 11 5D D P L D J19 Junction Connector D B 7 5D Y R Y 13 1A J20(A), J21(B) Junction Connector O7 Occupant Classification Sensor Front RH 16 5H B B E A 16 5L 13 IG2 9 IG2 8 1L L 12 B 8 B 2 B 7 A 1 A SIG2 SGD2 IG +B V Y 21 SVC3 SIG3 SGD3 SVC4 5 B 9 B 3 B 6 B SIG4 10 B SGD4 GND 4 B 3 A 11 R BR B 14 4 IG2 4 IG1 17 IG1 O9 Occupant Classification Sensor Rear RH R 3 SGD4 10 5D 4 4C 16 4C 8 5E 15 4H 4 4A W 2 SIG4 G 1 SVC4 BR 3 SGD3 R 2 SIG3 R 1 SVC3 W–B BR R V W Y GR SRS Power Supply Circuit 7 O8 Occupant Classification Sensor Rear LH C10 Combination Meter 10 IM2 O 4(A), O 5(B) Occupant Classification ECU SVC2 22 L 11 IM2 B 3 O SGD2 2 L SIG2 1 W SVC2 B P R W BP II 303 PRIUS (EM01R0U) SRS System Outline ∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the front airbag sensor and deceleration sensor. – Driver Airbag – Front Passenger Airbag – Seat Belt Pretensioner ∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the side airbag sensors. – Side Airbags – Curtain Shield Airbags ∗ The dual–stage SRS airbag system has been used for the driver and front passenger airbags.

signal to A/C control assembly. Then A/C control assembly flows electricity in TERMINAL Rr DEF, which activates DEF relay and mirror heater relay. As a result, rear DEF SW and mirror heater is turned on. Turning ON rear DEF SW of multi–display sends signal to A/C control assembly. Then the same action follows as above. During rear window defogger and mirror heater in operation, signal is input in combination meter, lighting rear DEF indicator in combination meter. : Parts Location Code See Page Code See Page Code See Page A7 A 48 J25 50 R15 A 54 A8 B 48 J26 53 R16 B 54 B5 A 48 J27 53 R19 54 C10 49 M12 50 R20 54 C12 49 M13 50 S11 51 G1 49 N7 54 T4 51 J6 50 P6 51 T5 51 J19 50 R13 A 54 T11 51 J24 50 R14 B 54 : Relay Blocks Code 3 See Page 22 Relay Blocks (Relay Block Location) Engine Room R/B (Engine Compartment Left) : Junction Block and Wire Harness Connector Code 1A 1G 1J See Page 30 1M Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) 30 1K 1L Junction Block and Wire Harness (Connector Location) Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 31 1N 4C 4D 4F 4H 38 Instrument Panel Wire and Center Connector No.1 (Behind the Combination Meter) 42 Instrument Panel Wire and Center Connector No.2 (Instrument Panel Brace RH) 4I 4K 4L 5B 5C 5D 5E 5G 5H 5J 5K 5L 5N 316 PRIUS (EM01R0U) : Connector Joining Wire Harness and Wire Harness Code ID1 See Page Joining Wire Harness and Wire Harness (Connector Location) 58 Instrument Panel Wire and Floor Wire (Left Kick Panel) 58 Front Door LH Wire and Instrument Panel Wire (Left Kick Panel) 59 Instrument Panel Wire and Instrument Panel No.2 Wire (Behind the Combination Meter) 59 Engine Wire and Instrument Panel Wire (Behind the Glove Box) 59 Front Door RH Wire and Instrument Panel Wire (Right Kick Panel) BH2 61 Back Door No.1 Wire and Floor Wire (Rear Side of Roof Panel) BK1 61 Back Door No.1 Wire and Back Door No.2 Wire (Rear Side of Roof Panel) IE1 IE2 IG1 IG2 II1 IL1 IL2 : Ground Points Code See Page Ground Points Location IH 58 Cowl Side Panel LH II 58 Instrument Panel Brace LH IJ 58 Instrument Panel Brace RH BL 60 Rear Side of Left Quarter Panel BO 60 Center of the Back Door Panel 317 PRIUS (EM01R0U) Automatic Glare–Resistant EC Mirror (BAT) (IG) 15A DOME 7. 5A ECU–IG 2 3 R 7 1L B O J6 Junction Connector R B 8 1L 8 5L 7 5I B 10 5I 1 IB1 2 IB1 B 7 5L R 16 5H R W 15 5H P 13 1A 10 6 +B IG E G3 Inner Mirror W–B 8 W–B 11 IB1 4 5I W–B 6 5L A J24 Junction Connector W–B A IH 318 PRIUS (EM01R0U) : Parts Location Code See Page G3 Code 53 J6 See Page 50 Code J24 See Page 50 : Relay Blocks Code 3 See Page 22 Relay Blocks (Relay Block Location) Engine Room R/B (Engine Compartment Left) : Junction Block and Wire Harness Connector Code See Page Junction Block and Wire Harness (Connector Location) 1A 30 Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) 1L 31 Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 42 Instrument Panel Wire and Center Connector No.2 (Instrument Panel Brace RH) 5H 5I 5L : Connector Joining Wire Harness and Wire Harness Code IB1 See Page 58 Joining Wire Harness and Wire Harness (Connector Location) Roof Wire and Instrument Panel Wire (Upper Parts of Front Body Pillar LH) : Ground Points Code IH See Page 58 Ground Points Location Cowl Side Panel LH 319 PRIUS (EM01R0U) Garage Door Opener (BAT) (IG) 15A DOME 7. 5A ECU–IG 2 3 B J6 Junction Connector O R 7 1L R B 8 1L 8 5L 7 5I B 10 5I 1 IB1 2 IB1 B 7 5L R 16 5H R W 15 5H P 13 1A 10 6 +B IG E G3 Garage Door Opener W–B 8 W–B 11 IB1 4 5I W–B 6 5L A J24 Junction Connector W–B A IH 320 PRIUS (EM01R0U) : Parts Location Code See Page G3 Code 53 J6 See Page 50 Code J24 See Page 50 : Relay Blocks Code 3 See Page 22 Relay Blocks (Relay Block Location) Engine Room R/B (Engine Compartment Left) : Junction Block and Wire Harness Connector Code See Page Junction Block and Wire Harness (Connector Location) 1A 30 Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) 1L 31 Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 42 Instrument Panel Wire and Center Connector No.2 (Instrument Panel Brace RH) 5H 5I 5L : Connector Joining Wire Harness and Wire Harness Code IB1 See Page 58 Joining Wire Harness and Wire Harness (Connector Location) Roof Wire and Instrument Panel Wire (Upper Parts of Front Body Pillar LH) : Ground Points Code IH See Page 58 Ground Points Location Cowl Side Panel LH 321 PRIUS (EM01R0U) Multi–Display and Audio System with Separate Amplifier R (BAT) B(∗1) 10A GAUGE R 15A DOME (IG) B V J6 Junction Connector V(∗1) V 2 B 12 5E 8 1L 14 5N 7 5K W R J10 Junction Connector 15 4C (∗1) 2 5E R 13 1A P V E (∗1) G (∗1) P V (∗1) 16 IG1 R V (∗1) E 16 5L B 3 R 19 1A (∗1) B 1 1M 6 3H 8 1G 16 5H 14 IA3 R A 12 5K 11 5E V V (∗1) V (∗1) R 23 8 3H Y 22 A 7 3H (∗1) P C10 Combination Meter V P 9 IG2 8 1F (∗1) 11 5D J10 Junction Connector 13 IG2 IJ3 L BK/UP LP Relay P Y 22 (∗1) 15 4I (∗1) 7 5D 21 (VFD) Power Supply Circuit 9 5K BEAN IC 2 4C 15 4H 13 4K W V 4 4C R 14 5K L 15 5K BR 13 5I B 12 5I 16 IG2 W 6 5D V 5 5D 10 IG1 Y 1 5D 13 B 2 5D 9 2 IG1 W 4 IG1 24 G 8 IG2 R 12 IG2 L 15 IG2 R 14 IG2 G BR 25 R 14 L 20 BR 12 B 31 GR 12 5D 15 6 IM1 5 IM1 1 IM1 8 IM1 2 3 1 2 Fuel Sender BR R 8 L–Y L 4 L–R BR 6 BR–R 5 Y B Y B GR Temp.

Turning on the SW sends signal to A/C control assembly, running the air conditioning system. 1. Heater Blower Operation Manual operation When the blower speed is set to a certain level using the blower control SW, the A/C control assembly sends the signals to the blower control to control the blower motor speed. Auto operation When the auto SW is pushed, the A/C control assembly calculates necessary blower speed from setting of SWs and input of the sensors and sends the signals to the blower control to automatically control the blower motor speed. 2. Air Inlet Control Servo Motor Control When the FRESH/RECIRC select SW is set to RECIRC, the air inlet control servo motor starts rotating to move the damper toward the RECIRC side. The damper position is detected by the TERMINAL TPI of the A/C control assembly. The motor continuously rotates until the damper reaches its stop position. When the FRESH/RECIRC select SW is set to FRESH, the air inlet control servo motor starts rotating to move the damper toward the FRESH side. The damper position is detected by the TERMINAL TPI of the A/C control assembly. The motor continuously rotates until the damper reaches its stop position. In auto mode, A/C control assembly controls the damper to move to the best position for the conditions without operating the mode select SW. 3. Air Vent Mode Control Servo Motor Control When the mode select SW is pushed, the ECU in the A/C control assembly activates the air vent mode control servo motor. The servo motor rotates to the position (FACE, BI–LEVEL, FOOT, FOOT/DEF, DEF) selected by using the mode select SW, and moves the damper. In auto mode, A/C control assembly controls the damper to move to the best position for the conditions without operating the mode select SW. 4. Air Mix Control Servo Motor Control Based on the set temperature by the temperature control SW, the ECU in the A/C control assembly sends a signal to the air mix control servo motor. This signal drives the motor to reach the temperature set by the temperature control SW, and moves the film damper. 5. Humidity Sensor Control A/C control assembly detects humidity in passenger room when A/C is turned on, with humidity detecting function of A/C room temp. sensor and controls to dehumidify for comfortable condition 6. Air Conditioning Operation A/C control assembly calculates target cooled temperature from information such as that of operating SWs, room temperature, humidity, ambient temperature and insolation to have target running speed of compressor assembly (Motor). The calculated control signal is sent to inverter to drive compressor assembly (Motor) (Electric motor) with control of inverter, resulting in operating A/C. 357 PRIUS (EM01R0U) Air Conditioning : Parts Location Code See Page A6 Code 46 See Page E1 Code See Page 46 J19 50 A7 A 48 E4 A 49 J24 50 A8 B 48 E5 B 49 J25 50 A9 48 E6 C 49 M13 50 A10 48 E7 D 49 P1 47 A11 48 49 P6 51 A14 48 H14 A 49 P12 51 A15 48 H15 B 49 A16 48 H16 C 49 S7 A 51 B2 48 I11 C 47 S8 B 51 G1 P13 51 B3 A 48 J6 50 S9 C 51 B4 B 48 J10 50 S10 D 51 B5 A 48 J12 50 S11 51 C4 F 46 J14 50 T4 51 C7 46 J15 50 T5 51 C10 49 J16 50 T11 51 C12 49 J17 50 W1 47 D1 49 J18 50 : Relay Blocks Code See Page Relay Blocks (Relay Block Location) 2 28 Engine Room R/B No.2 (Right Side of Reserve Tank) 3 22 Engine Room R/B (Engine Compartment Left) 358 PRIUS (EM01R0U) : Junction Block and Wire Harness Connector Code 1A 1C See Page 30 Junction Block and Wire Harness (Connector Location) Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) 1E 1G 30 1J 1K 1L 1M Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 31 1N 3B 3C 3H 23 Engine Room Main Wire and Engine Room J/B (Engine Compartment Left) 24 4C 4D 4F 4H 38 Instrument Panel Wire and Center Connector No.1 (Behind the Combination Meter) 42 Instrument Panel Wire and Center Connector No.2 (Instrument Panel Brace RH) 4I 4K 4L 5B 5C 5D 5E 5G 5H 5J 5K 5L : Connector Joining Wire Harness and Wire Harness Code EB1 See Page Joining Wire Harness and Wire Harness (Connector Location) 56 Engine Wire and Engine Room Main Wire (Inside of the Engine Room R/B) 58 Engine Room Main Wire and Instrument Panel Wire (Upper Parts of Front Body Pillar LH) 59 Instrument Panel Wire and Instrument Panel No.2 Wire (Behind the Combination Meter) II1 59 Engine Wire and Instrument Panel Wire (Behind the Glove Box) IJ3 59 Engine Room Main Wire and Instrument Panel Wire (Behind the Glove Box) IA2 IA3 IG1 IG2 : Ground Points Code See Page Ground Points Location EA 56 Right Side of the Fender Apron EC 56 Engine Block EF 56 Left Side of the Suspension Tower IH 58 Cowl Side Panel LH II 58 Instrument Panel Brace LH IJ 58 Instrument Panel Brace RH 359 PRIUS (EM01R0U) I GROUND POINT PTC Heater (WB) W–B Front Side Marker Light RH W–B W–B Headlight Assembly RH W–B (B–) W–B PTC Heater (B–) (∗3) W–B W–B W–B W–B W–B W–B Front Turn Signal Light RH Front Fog Light RH Pressure SW W–B Front Wiper Motor W–B Water Temp.
