1.CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the terminals and connectors of the combination meter for damage, bend and loose connection (unit side and connector side).

Is the inspection result normal?

YES >> GO TO 2.

NO >> Repair the terminal and connector.

2.CHECK HARNESS FOR OPEN CIRCUIT

1. Disconnect the connector of combination meter.

2. Check the resistance between the combination meter harness connector terminals.

NOTE: Check the vehicle type confirm the service information. Refer to MWI "Information".

- Models with Type A

- Models with Type B       

Is the measurement value within the specification?

YES >> GO TO 3.

NO >> Repair the combination meter branch line.

3.CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the combination meter. Refer to the following.

  • TYPE A: MWI "COMBINATION METER : Diagnosis Procedure"
  • TYPE B: MWI "COMBINATION METER : Diagnosis Procedure"

Is the inspection result normal?

YES (Present error)>>Replace the combination meter. Refer to the following.
