.

1.

CHECK FUSES

Check that the following fuses are not blown.

Is the fuse blown?

YES

>> Replace the blown fuse after repairing the affected circuit.

NO

>> GO TO 2.

2.

CHECK POWER SUPPLY CIRCUIT 

1. Disconnect combination meter connector.

2. Check voltage between combination meter harness connector M77 terminals 45, 46 and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace harness or connector.

3.

CHECK GROUND CIRCUIT 

1. Turn ignition switch OFF.

2. Check continuity between combination meter harness connector and ground.

Is the inspection result normal?

YES

>> Inspection End.

NO

>> Repair or replace harness or connector.
