GENERAL • The combination meter is digital display type. • The meter ECU maintains communication with other ECUs through the BEAN. It also maintains communication with the ECUs (or components) that compose the CAN and AVC-LAN through the gateway ECU. • The meter ECU and buzzer are installed in the combination meter. • The "READY" light comes on to inform the driver that the vehicle is ready to be driven. METER – METER / GAUGE SYSTEM 3. 4. ME–9 • The low ambient temperature indicator light comes on to inform the driver that the ambient temperature is low (below 3°C (6.6°F)). • The master warning light comes on with buzzer sounding if there is a malfunction in each system (see page ME-11). • The 2 inclination sensors are built in the combination meter to detect the inclination (longitudinal and latitudinal) of the vehicle. OIL REPLACEMENT REMINDER WARNING LIGHT (w/ REMINDER WARNING LIGHT) • 4,500 miles after ODO/TRIP switch is set, the maintenance indicator begins to blink for 15 seconds after the power switch is turned ON (ACC or IG). • 5,000 miles after ODO/TRIP switch is set, the maintenance indicator comes on. For resetting, refer to the following procedure (see page ME-23). FUEL GAUGE • For the purpose of correcting the calculation of the fuel level by the meter ECU, 2 inclination sensors that detect the vehicle's longitudinal and latitudinal inclinations are installed in the meter ECU. The fuel temperature sensor are installed in the fuel tank to detect the temperature in the fuel tank. • The fuel level is calculated by the meter ECU in accordance with the signals of the sender gauge located in the sub tank and the vehicle speed signal received from the brake ECU. At this time, corrections are made by the signals from the inclination sensor that detect the vehicle's longitudinal and latitudinal inclinations and the fuel temperature sensors that detects the temperature in the fuel tank. For the inclination sensor centered value setting, refer to the following procedure (see page ME-23). ME ME–10 METER – METER / GAUGE SYSTEM HOW TO PROCEED WITH TROUBLESHOOTING HINT: • Use these procedures to troubleshoot the meter / gauge system. • *: Use the intelligent tester. 1 VEHICLE BROUGHT TO WORKSHOP NEXT 2 ME INSPECT BATTERY VOLTAGE Standard voltage: 11 to 14 V If the voltage is below 11 V, recharge or replace the battery before proceeding.

Sit in front passenger seat. After turning the power switch ON (IG), press ODO / TRIP switch within 6 seconds, and hold it down for 10 seconds or more. 6 Continue holding down ODO / TRIP switch, move shift lever to R and press P switch Continue holding down ODO / TRIP switch, fasten driver seat belt Continue holding down ODO / TRIP switch, fasten front passenger seat belt 7 Check that odometer displays either "b-on" or "b-off"* Check that odometer displays either "b-on" or "b-off"* Check that odometer displays either "b-on" or "b-off"* 8 Press ODO / TRIP switch to change display to "b-off" Press ODO / TRIP switch to change display to "b-off" Press ODO / TRIP switch to change display to "b-off" 9 Turn power switch OFF Turn power switch OFF Turn power switch OFF 10 Turn power switch ON (IG) while depressing brake pedal. Check that combination meter displays "READY" Turn power switch ON (IG) while depressing brake pedal. Check that combination meter displays "READY" Turn power switch ON (IG) while depressing brake pedal. Check that combination meter displays "READY" 11 Check that no buzzer sounds when shift lever is in "R" Check that no buzzer sounds Check that no buzzer sounds when sitting on front passenger seat HINT: *: "b-off" indicates that the buzzer is OFF. "b-on" indicates that the buzzer is ON. The buzzer cancel setting will be finished (the odometer will display "ODO") if the ODO / TRIP switch is not operated for 10 seconds or more. In this case, perform step 11 to check that buzzer cancel setting is complete. If it is not complete, start from step 1 again. NOTICE: When either the battery cable or the combination meter connector is disconnected, these buzzers are set on.

H100769E18 Tester Connection Terminal Description Condition Specified Condition SIL (7) - SG (5) Bus "+" line During communication Pulse generation CG (4) - Body ground Chassis ground Always Below 1 Ω SG (5) - Body ground Signal ground Always Below 1 Ω BAT (16) - Body ground Battery positive Always 9 to 14 V METER – METER / GAUGE SYSTEM Intelligent Tester CAN VIM DLC3 A082795E04 ME–25 HINT: If the display inidcates UNABLE TO CONNECT TO VEHICLE when you have connected the cable of the intelligent tester (with CAN VIM) to the DLC3, turned the power switch ON (IG) and operated the tester, there is a problem either on the vehicle side or tester side. • If communication is normal when the tester is connected to another vehicle, inspect the DLC3 on the original vehicle. • If communication is still not possible when the tester is connected to another vehicle, the problem is probably in the tester itself, so consult the Service Department listed in the tester's instruction manual. ME ME–26 METER – METER / GAUGE SYSTEM DATA LIST / ACTIVE TEST 1. READ DATA LIST HINT: Using the intelligent tester's DATA LIST allows switch, actuator and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time. (a) Connect the intelligent tester (with CAN VIM) to the DLC3. (b) Turn the power switch ON (IG). (c) Read the DATA LIST according to the display on the tester.
