Inspection Procedure
- CHECK OPERATION OF SPEEDOMETER
- Drive the vehicle and check if the function of the speedometer in the combination meter is normal.
OK: Actual vehicle speed and the speed indicated on the speedometer are the same.
HINT:
The vehicle speed signal is normal when the indication on the speedometer is normal.
NG: CHECK COMBINATION METER
OK: Go to Next Step
- Drive the vehicle and check if the function of the speedometer in the combination meter is normal.
- INSPECT CLEARANCE WARNING ECU
- Disconnect the clearance warning ECU connector C9.
- Measure the voltage.
- Jack up either one of the drive wheels.
- Move the shift lever to the neutral position.
- Turn the ignition switch to the ON position.
- Measure the voltage between terminal SPD of the clearance warning ECU and body ground when a drive wheel is turned slowly.
OK: Voltage pulses as shown.
OK: REPLACE CLEARANCE WARNING ECU
NG: Go to Next Step
- CHECK HARNESS AND CONNECTOR (COMBINATION METER - CLEARANCE WARNING ECU)
- Disconnect the combination meter C10 connector.
- Measure the resistance according to the value(s) in the table below.
Standard resistance
TESTER CONNECTION AND SPECIFIED CONDITIONTester connection Condition Specified condition SPD - C10-36 Ignition switch off Below 1 Ω
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to Next Step
- CHECK HARNESS AND CONNECTOR (COMBINATION METER AND EACH ECU - BODY GROUND)
- Measure the resistance according to the value(s) in the table below.
Standard resistance
TESTER CONNECTION AND SPECIFIED CONDITIONTester connection Condition Specified condition SPD - Body ground Ignition switch off 10 kΩ or higher HINT:
If the resistance between terminal SPD and body ground is less than 10 kΩ, there may be a short in a wire harness, connector, or ECU.
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR OR CHECK EACH ECU
OK: REPLACE COMBINATION METER
- Measure the resistance according to the value(s) in the table below.
