1 CHECK VEHICLE SPEED SENSOR.
- Lift-up the vehicle and support it with safety stands.
- Remove the combination meter with harness connector.
- Drive the vehicle at a speed greater than 20 km/h (12 MPH).
WARNING:
Be careful not to get caught in the running wheels.
- Measure voltage between combination meter connector and chassis ground.
Connector & terminal
(I10) No. 13 (+) - Chassis ground (-):
|
Is the measured value less than 1 V or more than 5 V? |
Check speedometer. < Ref. to
REMOVAL , SPEEDOMETER. > |
Go to step 2. |
2 CHECK VEHICLE SPEED SENSOR POWER SUPPLY.
- Turn ignition switch to OFF.
- Disconnect vehicle speed sensor harness connector.
- Turn ignition switch to ON.
- Measure voltage between vehicle speed sensor connector and engine ground.
Connector & terminal
(B17) No. 3 (+) - Engine ground (-):
|
Is the measured value more than 10 V? |
Go to step 3. |
Check harness for open or short between ignition relay and vehicle speed sensor. |
3 CHECK HARNESS BETWEEN VEHICLE SPEED SENSOR AND ENGINE GROUND.
- Turn ignition switch to OFF.
- Measure resistance between vehicle speed sensor connector and engine ground.
Connector & terminal
(B17) No. 2 - Engine ground:
|
Is the measured value less than 10 Ω? |
Go to step 4. |
Repair wiring harness. |
4 CHECK HARNESS BETWEEN VEHICLE SPEED SENSOR AND COMBINATION METER.
- Disconnect connector from combination meter.
- Measure resistance between vehicle speed sensor harness connector and combination meter harness connector.
Connector & terminal
(B17) No. 1 - (110) No. 13:
|
Is the measured value less than 10 Ω? |
Replace vehicle speed sensor. |
Repair wiring harness. |
