COMBINATION SWITCH INPUT CIRCUIT

COMBINATION SWITCH INPUT CIRCUIT

Diagnosis Procedure

INFOID:0000000003809625

1.

CHECK INPUT 1 - 5 SYSTEM CIRCUIT FOR OPEN

1.

Turn the ignition switch OFF.

2.

Disconnect the BCM and combination switch connectors.

3.

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

Does continuity exist?

YES

>> GO TO 2.

NO

>> Repair the harnesses or connectors.

2.

CHECK INPUT 1 - 5 SYSTEM CIRCUIT FOR SHORT

Check for continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> Repair the harnesses or connectors.

NO

>> GO TO 3.

3.

CHECK BCM OUTPUT VOLTAGE

1.

Connect the BCM connector.

2.

Check voltage between BCM harness connector and ground.

Is the measurement value normal?

YES

>> GO TO 4.

NO

>> Replace BCM. Refer to 

BCS-78, "Exploded View"

.

CHECK BCM INPUT SIGNAL

1.

Connect the combination switch connector.

2.

Turn ON any switch in the system that is malfunctioning.

3.

Check voltage between BCM harness connector and ground.

Is the measurement value normal when any of the switches is turned ON?

YES

>> Replace BCM. Refer to 

BCS-78, "Exploded View"

NO

>> Replace the combination switch.

COMBINATION SWITCH OUTPUT CIRCUIT

Diagnosis Procedure

INFOID:0000000003809626

1.

CHECK OUTPUT 1 - 5 SYSTEM CIRCUIT FOR OPEN

1.

Turn the ignition switch OFF.

2.

Disconnect the BCM and combination switch connectors.
NOTE:
BCM connector disconnects M123 only.

3.

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

Does continuity exist?

YES

>> GO TO 2.

NO

>> Repair the harnesses or connectors.

2.

CHECK OUTPUT 1 - 5 SYSTEM CIRCUIT FOR SHORT

Check for continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> Repair the harnesses or connectors.

NO

>> GO TO 3.

3.

CHECK COMBINATION SWITCH INTERNAL CIRCUIT

1.

Connect the combination switch connector.

2.

Turn ON any switch in the system that is malfunctioning.

3.

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