Toyota Corolla Repair Manual: Malfunction in speedometer
Wiring diagram
Inspection procedure
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.
- Select the data list mode on the hand–held tester.
- Check that there is no difference between the speed value output
from the speed sensor displayed

the vehicle.
Ok: there is almost no difference from the displayed speed value.
Repair or replace harness or connector
3 Inspect speedometer sensor
- Check voltage.
- Shift the shift lever to neutral.
- Jack up either of the front wheel.
- Turn the ignition switch to on.
- Measure voltage between terminals 3 and 2 of speed sensor when the front wheel is turning slowly.
Standard voltage: voltage is generated intermittently.
