Diagnosis Procedure

INFOID:0000000003140191

1.

CHECK CONNECTOR

Check combination meter, unified meter and A/C amp. and terminals (combination meter side, unified meter
and A/C amp. side, and harness side) for looseness or bent.
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair terminal or connector.

2.

CHECK CONTINUITY COMMUNICATION CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect combination meter connector and unified meter and A/C amp. connector.

3.

Check continuity between combination meter harness connector and unified meter and A/C amp. harness
connector.

4.

Check continuity between combination meter harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair harness or connector.

3.

CHECK UNIFIED METER AND A/C AMP. OUTPUT VOLTAGE

1.

Connect unified meter and A/C amp. connector.

2.

Turn ignition switch ON.

3.

Check voltage between unified meter and A/C amp. harness connector and ground.
