1 Check combination meter assy
- Remove the combination meter assy with connector still connected.
- check voltage.
- Jack up either of the front wheels.
- Shift the shift lever to neutral.
- Turn the ignition switch to on.
- Measure the voltage between terminals c9–9 of combination meter assy and body ground when front wheel is turning slowly.
Standard voltage: voltage is generated intermittently.
Result:
Check and replace combination meter assy
2 Check obd ii scan tool or hand–held tester
- Check output value of skid control ecu.
- Connect the hand–held tester to dlc3.
- Turn the ignition switch to on and push the hand–held tester main switch on.
