DL POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION The power door lock system locks/unlocks all the doors simultaneously. The master switch (on the driver side door) and the door control switch (on the passenger side door) send lock/ unlock request signals to the body ECU. Then, the body ECU sends these requests to the lock motors in each door to lock/unlock all the doors simultaneously. Operating the driver side door lock using a key sends lock/unlock request signals to the door lock control relay. The driver side door key-linked lock function has an optional unlock method called the 2-step unlock function. FUNCTION OF MAIN COMPONENT Components Function Master switch Door control switch on master switch assembly locks/unlocks all doors Door control switch Door control switch on passenger side door locks/unlocks all doors Door courtesy switch Placed on each door. Detects door status (open or closed) and outputs data to body ECU. Turns on when door is open and turns off when door is closed.

DL WIRELESS DOOR LOCK CONTROL SYSTEM DESCRIPTION (a) This system locks and unlocks the vehicle's doors remotely. The wireless door lock control system has the following features: • The door control receiver performs the code identification process and the main body ECU operates the door lock control. A serial data link is provided for communication between the door control receiver and main body ECU. • A key-integrated type transmitter is used and it contains the following 3 switches: the LOCK switch, UNLOCK switch and PANIC switch. • An LED is mounted on the transmitter to show if the battery is depleted. FUNCTION OF MAIN COMPONENTS Components Functions • • Door control transmitter • Contains LOCK, UNLOCK and PANIC switches Transmits faint electric wave (recognition codes and function codes) to door control receiver Illumination indicator light (LED) during transmission Door control receiver Receives faint electric waves (recognition code and function codes) and outputs them as code data to main body ECU Key slot (halfway switch) Detects if key slot has key or not Front door courtesy light switch Rear door courtesy light switch Back door courtesy light switch Turns on when door is open and turns off when door is closed. Outputs door status (open or closed) to main body ECU. Door lock position switch Transmits door lock positions of each door to main body ECU 3. SYSTEM FUNCTION (a) Door lock/unlock function: With no key in the key slot (halfway switch is off) and all courtesy light switches off, pressing the door control transmitter's LOCK/UNLOCK switch causes the transmitter to output electric waves which are input to the door control receiver. The door control receiver converts these waves into code data in its internal high frequency circuit, and outputs the code data to the main body ECU. The door control receiver and certification ECU evaluate the code data (recognition codes and function codes) and output the evaluation results to the main body ECU. Upon receiving a door lock/unlock request signal, the main body ECU outputs a door lock/unlock control signal to each door lock. Each door lock then locks/unlocks its respective door and turns on/off its door lock position switch according to the signal. DOOR LOCK – WIRELESS DOOR LOCK CONTROL SYSTEM (w/ Smart Key System) DL–59 (b) Answer-back function: The main body ECU receives the door unlock detection switch's on/off signals and uses these signals to confirm if door control operation has completed. The main body ECU then outputs the hazard warning light's output control signal to flash the hazard warning light as an answer-back and wireless door lock buzzer signals to cause the wireless door buzzer to sound as an answer-back. (c) Panic function: When the door control transmitter's PANIC switch is pressed, the door control receiver and certification ECU evaluate the code data (recognition codes and function codes) from the door control transmitter in the same way as when the LOCK/UNLOCK switch is pressed. Upon receiving a theft deterrent alarm control signal from the certification ECU, the main body ECU actuates a built-in relay to causer the security horn to sound, as well as transmit several kinds of warning signals (hazard warning light control signal, vehicle horn warning control signal, headlight warning signal and taillight warning signal) in order to output a theft deterrent alarm. (d) The wireless door lock control system has the following functions. Function Outline All door unlock function Pressing LOCK switch locks all doors All door unlock function (for 2 step unlock operation) Pressing UNLOCK switch once will unlock driver side door. Pressing UNLOCK switch again within 3 seconds will unlock remaining doors. • Answer-back function • Hazard warning lights flash once when doors are locked, and flash twice when doors are unlock to inform that operation has been completed Wireless door lock buzzer sounds once when doors are locked and sounds twice when doors are unlocked to inform that operation has been completed Panic function Holding down PANIC switch sets off theft deterrent alarm, which consists of sounding horn, and flashing headlights, taillights and hazard warning lights Automatic lock function If no doors are opened within 30 seconds after they are unlocked by wireless door lock remote control, all doors will lock again automatically Repeat function If door is not locked in response to locking operation of transmitter, main body ECU will output lock signal after 1 second Illuminated entry function With all doors locked, pressing door unlock switch causes room light to illuminate simultaneously with unlocking operation Security function Sends signal as rolling code Transmitter recognition code registration function Enables 4 modes for registering (writing and storing) transmitter recognition codes in EEPROM, which is built into main body ECU Self-diagnosis If system has malfunction, main body ECU sets DTC in its memory DL DL–60 DOOR LOCK – WIRELESS DOOR LOCK CONTROL SYSTEM (w/ Smart Key System) HOW TO PROCEED WITH TROUBLESHOOTING HINT: • Use these procedures to troubleshoot the wireless door lock control system. • *: Use the intelligent tester. 1 VEHICLE BROUGHT TO WORKSHOP NEXT 2 INSPECT BATTERY VOLTAGE Standard voltage: 11 to 14 V If the voltage is below 11 V, recharge or replace the battery before proceeding DL NEXT 3 INSPECT COMMUNICATION FUNCTION OF LARGE-SCALE MULTIPLEX COMMUNICATION SYSTEM (BEAN)* (a) Using the intelligent tester, check if the Multiplex Communication System (MPX) is functioning normally (see page MP-16).

DL 2. NOTES WHEN CHECKING (a) Wireless door LOCK/UNLOCK function: This function operates only when the following 4 conditions are met. • No key is inserted into the key slot. • All the doors are closed. • The power door lock control system is functioning normally. • Key is not within the key detection area. HINT: The UNLOCK function operates even when one of the doors is open. (b) Panic function: This wireless control function operates only when the following condition is met. • The power switch must be OFF. HINT: The key can be inserted. However the power switch must be OFF. (c) The wireless transmitter operating range differs depending on the situation. • The operating range differs depending on the user, the way the transmitter is held and the location. • In certain areas, the operating range will be reduced due to the vehicle body shape and the influence of the surrounding environment. • Since the transmitter uses faint electric waves, the operating range might be shortened if noise or strong electric waves occur in the area where the transmitter is used. Or, the transmitter may not function. • When the battery weakens, the operating range is reduced or the transmitter may not function. HINT: If the transmitter has been left in a place that is exposed to direct sunlight, such as on the instrument panel, the battery may weaken or other problem may occur. WIRELESS DOOR LOCK CONTROL FUNCTIONS HINT: • The switches described below transmit signals and are built into the door control transmitter. • The operating range must be taken into account while checks are being made. (a) Make sure the vehicle is in a condition where the wireless door lock control function can be operated (see above). (b) Check basic functions: • Check that the transmitter's LED illuminates 3 times when each switch is pressed 3 times. DOOR LOCK – WIRELESS DOOR LOCK CONTROL SYSTEM (w/ Smart Key System) (c) (d) (e) (f) (g) (h) DL–63 HINT: If the LED does not illuminate when the switch has been pressed 3 times or more, the battery may be depleted. • Check that all doors (including the back door) lock when the LOCK switch is pressed. • Check that only the driver side door unlocks when the UNLOCK switch is pressed once, and that the remaining doors unlock when the UNLOCK switch is pressed again within 3 seconds. Check the chattering prevention function: • Check that pressing a switch will result in the switch's operation occurring only once; and when the switch is held down, the operation is not repeated continuously. Also, make sure that when the switch is pressed at intervals of approximately 1 second, the switch's operation activates once for every press of the switch. Check the automatic locking function: • Check that if all of the doors are unlocked with the UNLOCK switch and none of the doors are opened or locked within approximately 30 seconds, the door automatically relocks. • Check that if all of the doors are unlocked with the UNLOCK switch and a door is opened or locked within approximately 30 seconds, the automatic locking function does not operate. Check the switch operation fail-safe function: • Check that the doors cannot be locked by a transmitter switch while the key is in the key slot. However, this does not apply when the system is in recognition code registration mode. Check the operation stop function when a door is open or not completely closed: • Check that if a door is open or not completely closed, the doors cannot be locked by the LOCK switch. Check the repeat function: • Check that if the LOCK switch is pressed while the movement of the driver side door control knob (in the unlocked state) is restricted, the repeat function attempts to lock all of the doors again 2 seconds later. Check the answer-back function: • When the LOCK switch is pressed, confirm the simultaneous occurrence of all the hazard warning lights flashing once, the buzzer sounding once and all the doors locking. • When the UNLOCK switch is pressed, confirm the simultaneous occurrence of all the hazard warning lights flashing twice, the buzzer sounding twice and the driver side door unlocking. DL DL–64 DOOR LOCK – WIRELESS DOOR LOCK CONTROL SYSTEM (w/ Smart Key System) (i) (j) DL • When UNLOCK switch is pressed again within 3 seconds, conform the simultaneous occurrence of all the hazard warning lights flashing twice, the buzzer sounding twice and all the doors unlocking. Check the illuminated entry function: • When all the doors are locked, pressing the UNLOCK switch causes the room light (when the light switch is in the DOOR position) to illuminate simultaneously with the unlock operation. • Check that the room light turns off in approximately 15 seconds if doors have not been opened. Check the panic function: (1) Check that if PANIC switch is held down for 0.8 seconds or more, the theft deterrent alarm function sounds the horn and flashes the headlights and taillights for 60 seconds. And, with the theft alarm function active, check if pressing any switch on the transmitter causes the horn to stop sounding and the headlights and taillights to stop flashing.

DL WIRELESS DOOR LOCK CONTROL SYSTEM DESCRIPTION (a) This system is locks and unlocks the vehicle's doors remotely. The wireless door lock control system has the following features: • The door control receiver performs the code identification process and the main body ECU operates the door lock control. A serial data link is provided for communication between the door control receiver and main body ECU. • A key-integrated type transmitter is used and it contains the following 3 switches: the door lock switch, door unlock switch and panic switch. • An LED is mounted on the transmitter to show if the battery is depleted. FUNCTION OF MAIN COMPONENTS Components Functions • • Door control transmitter • Contains LOCK, UNLOCK and PANIC switches Transmits faint electric waves (recognition codes and function codes) to door control receiver Illuminates indicator light (LED) during transmission Door control receiver Receives faint electric waves (recognition codes and function codes) and outputs them as code data to main body ECU Key slot (halfway switch) Detects if key slot has key or not Front door courtesy light switch Rear door courtesy light switch Back door courtesy light switch Turn on when door is open and turns off when door is closed. Outputs door status (open or closed) to main body ECU Door lock position switch Transmits door lock positions of each door to main body ECU 3. SYSTEM FUNCTION (a) Door lock/unlock function: With no key in the key slot (halfway switch is off) and all door courtesy light switches off, pressing the door control transmitter's LOCK/UNLOCK switch causes transmitter to output faint electric waves which are input to the door control receiver. The door control receiver converts these waves into code data in its internal high frequency circuit and outputs the code data (recognition codes and function codes) to the main body ECU. Upon receiving a door lock/unlock request signal, the main body ECU outputs a door lock/unlock control signal to each door lock. Each door lock then locks/ unlocks its respective door and turns on/off its door lock position switch according to the signal. (b) Answer-back function: The main body ECU receives the door unlock detection switch's on/off signals and uses these signals to confirm if door control operation has completed. The main body ECU then outputs the hazard warning lights's output control signals to flash the hazard warning light as an answer-back. DOOR LOCK – WIRELESS DOOR LOCK CONTROL SYSTEM (w/o Smart Key System) DL–91 (c) Panic function: When the door control transmitter's PANIC switch is pressed, the door control receiver receives the code data (recognition codes and function codes) from the door control transmitter in the same way as when the LOCK/UNLOCK switch is pressed. Upon receiving a theft deterrent alarm control signal, the main body ECU actuates a built-in relay to cause the security horn to sound, as well as transmit several kinds of warning signals (hazard warning light control signal, vehicle horn warning control signal, headlight warning signal and taillight warning signal) in order to output a theft deterrent alarm. (d) The wireless door lock control system has the following functions. Function Outline All door unlock function Pressing LOCK switch locks all doors. All door unlock function (for 2 step unlock operation) Pressing UNLOCK switch once will unlock driver side door. Pressing UNLOCK switch again within 3 seconds will unlock remaining doors. Answer-back function Hazard warning lights flash once when doors are locked, and flash twice when doors are unlocked to inform that operation has been completed Panic function Holding down PANIC switch sets off theft deterrent alarm, which consists of sounding horn, and flashing headlights, taillights and hazard warning lights Automatic lock function If no doors are opened within 30 seconds after they are unlocked by wireless door lock remote control, all doors will lock again automatically Repeat function If door is not locked in response to locking operation of transmitter, main body ECU will output lock signal after 1 second Illuminated entry function With all doors locked, pressing UNLOCK switch causes room light to illuminate simultaneously with unlocking again Security function Sends signal as rolling code Transmitter recognition code registration function Enables 3 modes for registering (writing and storing) transmitter recognition codes in EEPROM, which is built into main body ECU Self-diagnosis If system has malfunction, main body ECU sets DTC in its memory DL DL–92 DOOR LOCK – WIRELESS DOOR LOCK CONTROL SYSTEM (w/o Smart Key System) HOW TO PROCEED WITH TROUBLESHOOTING HINT: • Use these procedures to troubleshoot the wireless door lock control system. • *: Use the intelligent tester. 1 VEHICLE BROUGHT TO WORKSHOP NEXT 2 INSPECT BATTERY VOLTAGE Standard voltage: 11 to 14 V If the voltage is below 11 V, recharge or replace the battery before proceeding DL NEXT 3 INSPECT COMMUNICATION FUNCTION OF LARGE-SCALE MULTIPLEX COMMUNICATION SYSTEM (BEAN)* (a) Using the intelligent tester, check if the Multiplex Communication System (MPX) is functioning normally (see page MP-16).

DL 2. NOTES WHEN CHECKING (a) Wireless door LOCK/UNLOCK function: This function operates only when the following 4 conditions are met. • No key is inserted into the key slot. • All the doors are closed. • The power door lock control system is functioning normally. HINT: The UNLOCK function operates even when one of the doors is open. (b) Panic function: This wireless control function operates only when the following condition is met. • The power switch must be OFF. HINT: The key can be inserted. However the power switch must be OFF. (c) The wireless transmitter operating range differs depending on the situation. • The operating range differs depending on the user, the way the transmitter is held and the location. • In certain areas, the operating range will be reduced due to the vehicle body shape and the influence of the surrounding environment. • Since the transmitter uses faint electric waves, the operating range might be shortened if noise or strong electric waves occur in the area where the transmitter is used. Or, the transmitter may not function. • When the battery weakens, the operating range is reduced or the transmitter may not function. HINT: If the transmitter has been left in a place that is exposed to direct sunlight, such as on the instrument panel, the battery may weaken or other problem may occur. WIRELESS DOOR LOCK CONTROL FUNCTIONS HINT: • The switches described below transmit signals and are built into the door control transmitter. • The operating range must be taken into account while checks are being made. (a) Make sure the vehicle is in a condition where the wireless door lock control function can be operated (see above). (b) Check basic functions: • Check that the transmitter's LED illuminates 3 times when each switch is pressed 3 times. DOOR LOCK – WIRELESS DOOR LOCK CONTROL SYSTEM (w/o Smart Key System) (c) (d) (e) (f) (g) (h) DL–95 HINT: If the LED does not illuminate when the switch has been pressed 3 times or more, the battery may be depleted. • Check that all doors (including the back door) lock when the LOCK switch is pressed. • Check that only the driver side door unlocks when the UNLOCK switch is pressed once, and that the remaining doors unlock when the UNLOCK switch is pressed again within 3 seconds. Check the chattering prevention function: • Check that pressing a switch will result in the switch's operation occurring only once; and when the switch is held down, the operation is not repeated continuously. Also, make sure that when the switch is pressed at intervals of approximately 1 second, the switch's operation activates once for every press of the switch. Check the automatic locking function: • Check that if all of the doors are unlocked with the UNLOCK switch and none of the doors are opened or locked within approximately 30 seconds, the door automatically relocks. • Check that if all of the doors are unlocked with the UNLOCK switch and a door is opened or locked within approximately 30 seconds, the automatic locking function does not operate. Check the switch operation fail-safe function: • Check that the doors cannot be locked by a transmitter switch while the key is in the key slot. However, this does not apply when the system is in recognition code registration mode. Check the operation stop function when a door is open or not completely closed: • Check that if a door is open or not completely closed, the doors cannot be locked by the LOCK switch. Check the repeat function: • Check that if the LOCK switch is pressed while the movement of the driver side door control knob (in the unlocked state) is restricted, the repeat function attempts to lock all of the doors again 2 seconds later. Check the answer-back function: • When the LOCK switch is pressed, confirm the simultaneous occurrence of all the hazard warning lights flashing once, the buzzer sounding once and all the doors locking. • When the UNLOCK switch is pressed, confirm the simultaneous occurrence of all the hazard warning lights flashing twice and the driver side door unlocking. DL DL–96 DOOR LOCK – WIRELESS DOOR LOCK CONTROL SYSTEM (w/o Smart Key System) (i) (j) DL • When UNLOCK switch is pressed again within 3 seconds, conform the simultaneous occurrence of all the hazard warning lights flashing twice and all the doors unlocking. Check the illuminated entry function: • When all the doors are locked, pressing the UNLOCK switch causes the room light (when the light switch is in the DOOR position) to illuminate simultaneously with the unlock operation. • Check that the room light turns off in approximately 15 seconds if doors have not been opened. Check the panic function: (1) Check that if PANIC switch is held down for 0.8 seconds or more, the theft deterrent alarm function sounds the horn and flashes the headlights and taillights for 60 seconds. And, with the theft alarm function active, check if pressing any switch on the transmitter causes the horn to stop sounding and the headlights and taillights to stop flashing.

Hybrid Vehicle Control ECU Starts hybrid system upon receiving system start signal from power source control ECU (ON (READY)). Receives hybrid system start authorization signal from transponder key ECU. Main Body ECU Transmits body control system signals (courtesy switch, door key lock/ unlock switch, door lock position switch, halfway switch signals, etc.) to certification ECU via BEAN. Receives door lock/unlock request signal from certification ECU via dedicated serial communication line (with local protocol), which is used between main body ECU, certification ECU and door control receiver. 3. SYSTEM FUNCTION (a) Entry unlock • For the system to be able to detect the location of the key, the vehicle doors must be locked. The door oscillators transmit key detection signals at prescribed intervals in order to form vehicle exterior detection areas (0.7 to 1.0 m (2.3 to 3.3 ft.)). • When the key is brought into a detection area, the system automatically checks the key's ID code. When this is completed, the door that has detected the key enters the unlock standby condition in accordance with the prescribed unlock mode. In this condition, if the touch sensor on the outside door handle is touched, all doors unlock.

After the check is completed, the certification ECU unlocks* the back door via the main body ECU. At this time, if the user continues to press the back door opener switch, the back door lock latch will be released. HINT: *: If entry unlock is set to individual door unlock mode, only the back door will be unlocked.

DL–132 DOOR LOCK – SMART KEY SYSTEM (c) Entry lock • When the key is located outside the vehicle and all doors are closed, if the user presses the lock switch on the outside door handle or the lock switch on the back door, the certification ECU will actuate all oscillators and start checking for the ID code of a key. • At this time, if an oscillator outside the vehicle (driver's/front passenger's door electrical key oscillator or luggage electrical key oscillator (outer)) determines that the key ID code is legitimate, the certification ECU determines that the key has been taken outside the vehicle and locks all doors via the main body ECU. • An entry unlock operation will not be authorized for approximately 3 seconds* after the doors have been locked. HINT: *: The setting of this duration can be changed using the customize function. For details, see CUSTOMIZE PARAMETERS (see page DL-144).

Accordingly, the key sends an ID code signal to the certification ECU via the door control receiver. The certification ECU checks the ID code of the key and transmits the check results to the transponder key ECU. • The transponder key ECU transmits the check results to the power source control ECU. If the check results show that the ID code is legitimate, the power source control ECU will turn on the ACC relay and start the ACC power supply. At this time, the power source control ECU illuminates a green indicator light on the power switch in order to inform the driver of the ON (ACC) status. • After the transition to the ON (ACC) status, if the driver presses the power switch again, the power source control ECU will turn on the IG1 and IG2 relays and start the IG power supply. At this time, the power source control ECU illuminates an amber indicator light on the power switch in order to inform the driver of the ON (IG) status.

Accordingly, the key sends an ID code signal to the certification ECU via the door control receiver. DOOR LOCK – SMART KEY SYSTEM DL–135 The certification ECU checks the ID code of the key and transmits the check results to the transponder key ECU. The transponder key ECU transmits the check results to the power source control ECU. If the check results reveal that the ID code is legitimate, the power source control ECU will turn on the ACC, IG1 and IG2 relays and start the ACC and IG power supply. At this time, the power source control ECU illuminates an amber indicator light on the power switch in order to inform the driver of the ON (IG) status. After the indicator light has illuminated, the power source control ECU transmits a hybrid system start request signal to the hybrid vehicle control ECU. Upon receiving this signal, the hybrid vehicle control ECU verifies the check results of the key ID code provided by the transponder key ECU. If the check results reveal that the ID code is legitimate, the hybrid vehicle control ECU starts the hybrid system. At this time, the power source control ECU will turn off the indicator light on the power switch in order to inform the driver of the ON (READY) status.

If the hybrid control system starts (the transponder key ECU outputs a start permission to the hybrid control system and the hybrid control system starts), it can be assumed that only the entry ignition system is malfunctioning. The certification ECU uses the indoor electrical key oscillator to send a request signal to the key when: 1) the driver's door is opened and closed, or 2) the power switch is changed from ON (ACC) to OFF or OFF to ON. Then, the key transmits its ID code to the door control receiver. The ID code, which is then sent to the certification ECU, is verified by the certification ECU and the verification result is sent to the transponder key ECU. The transponder key ECU and the certification ECU communicate encryption codes to each other using the multiplex communication line. When the return code from the certification ECU matches the ID code in memory, the transponder key ECU sends a hybrid control system start permission signal to the hybrid control ECU. Pressing the power switch while depressing the brake pedal then starts the hybrid control system. With the vehicle stopped, pressing the power switch again stops the hybrid control system.

DL KEY REMINDER WARNING SYSTEM DESCRIPTION (a) The key reminder warning system sounds the combination meter buzzer as a warning when the following occur simultaneously: 1) the power switch is set to OFF or ON (ACC), 2) the key is inserted into the key slot, and 3) the driver side door is opened. FUNCTION OF COMPONENT Components Function Front door courtesy light switch LH Detects if driver side door is open or closed and outputs data to multiplex network body ECU. Key slot (Halfway switch) Detects if key is / is not in key slot and outputs data to transponder key ECU. Combination meter Receives buzzer request signal from transponder key ECU (after transponder key ECU receives halfway switch signal and front door courtesy light switch LH signal). Then combination meter actuates driver circuit to sound built-in multi-buzzer intermittently. 3. FUNCTION OF DESCRIPTION (a) The key slot transmits a halfway switch status signal to the transponder key ECU. The front door courtesy light switch LH transmits a driver side door courtesy switch status signal to the multiplex network body ECU. With the power switch OFF or ON (ACC), 2 conditions are required to activate the key reminder warning system: 1) the transponder key ECU receives a signal indicating that the key is in the key slot, and 2) the transponder key ECU receives a driver side door open signal via the multiplex network body ECU. If both conditions are satisfied, a buzzer request signal is transmitted from the transponder key ECU to the combination meter assembly via the BEAN. The combination meter assembly then actuates the driver circuit to sound a built-in multi-buzzer intermittently.

Release Knob Emergency Key B080555E01 DOOR LOCK – DOOR CONTROL TRANSMITTER DL–217 DOOR CONTROL TRANSMITTER INSPECTION 1. B074738E01 INSPECT DOOR CONTROL TRANSMITTER (a) Inspect operation of the transmitter. (1) Remove the battery (lithium battery: CR1632) from the transmitter (see page DL-215). (2) Install a new or non-depleted battery. HINT: When a new or non-depleted transmitter battery is not available, connect 2 new 1.5 V batteries in series. Then connect leads to the batteries and use the leads to apply voltage of 3 V to the transmitter, as shown in the illumination. (3) From outside the vehicle, approximately 1 m (3.28 ft.) from the driver the outside door handle, test the transmitter by pointing transmitter at the vehicle and pressing a transmitter switch. OK: Door lock can be operated via transmitter. HINT: • The operating range differs depending on the user, the way the transmitter is held and the location. • Since the transmitter uses faint electric waves, the operating range might be shortened if noise or strong electric waves occur in the area where the transmitter is used. Or, the transmitter may not function. (b) Install the battery (see page DL-216). (c) Inspect the battery capacity. HINT: • When checking the amount of energy left in the battery, the battery must be checked while it is installed in the transmitter (a resistance of 1.2 kΩ is applied to the battery). When the battery energy is checked by itself (uninstalled), the voltage reading will be more than 2.5 V until the energy is depleted. • If the transmitter is malfunctioning, the voltage reading of the energy left in the battery may be inaccurate. (1) Remove the battery from the transmitter. DL DL–218 DOOR LOCK – DOOR CONTROL TRANSMITTER (2) Connect a wire to the negative (-) terminal of the transmitter and install the battery. Wire B074739E01 DL B074740E01 (3) Connect the tester's positive (+) lead to the battery's positive (+) terminal and the negative (-) lead to the wire. (4) Press one of the transmitter switches for approximately 1 second. (5) Press the transmitter switch again and check the voltage. Standard voltage: 2.2 V or higher HINT: • When the temperature of the battery is low, the inspection cannot be made correctly. When the outcome of the test is less than 2.2 V, conduct the test again after leaving the battery in a place with a temperature 18°C (64°F) for more than 30 minutes. • Read the voltage immediately after the switch is pressed. When 0.8 seconds have pressed after the switch is pressed, the automatic power-off function starts and resistance applied to the battery will cease. The voltage of the battery will be 2.5 V or more. • Press the switch at least 3 times before reading the voltage. If the battery has just been returned to 18°C (64°F), the voltage may be unusually high for the first or second voltage reading. (6) Disconnect the lead. (7) Set the battery in the transmitter.
