POWER SUPPLY AND GROUND CIRCUIT

POWER SUPPLY AND GROUND CIRCUIT

Diagnosis Procedure

INFOID:0000000010688625

1.

CHECK FUSE AND FUSIBLE LINK

Check that the following fuse and fusible link are not blown.

Is the fuse fusing?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is

blown.

NO

>> GO TO 2.

2.

CHECK POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect BCM connectors.

3.

Check voltage between BCM harness connector and ground.

Is the measurement value normal?

YES

>> GO TO 3.

NO

>> Repair harness or connector.

3.

CHECK GROUND CIRCUIT

Check continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> INSPECTION END

NO

>> Repair harness or connector.

COMBINATION SWITCH OUTPUT CIRCUIT

Diagnosis Procedure

INFOID:0000000010688626

1.

CHECK OUTPUT 1 - 5 CIRCUIT FOR OPEN

1.

Turn ignition switch OFF.

2.

Disconnect BCM and combination switch connectors.
NOTE:
BCM connector disconnects M86 and M87 only.

3.

Check continuity between BCM harness connector and combination switch harness connector.

Does continuity exist?

YES

>> GO TO 2.

NO

>> Repair harnesses or connectors.

2.

CHECK OUTPUT 1 - 5 CIRCUIT FOR SHORT

Check for continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> Repair harnesses or connectors.

NO

>> GO TO 3.

3.

CHECK COMBINATION SWITCH INTERNAL CIRCUIT

1.

Connect combination switch connector.

2.

Turn ON any switch in the system that is malfunctioning.

3.

Check voltage between BCM harness connector and ground.
NOTE:
Check that the combination switch outputs a signal from combination switch input system.
