Diagnosis Procedure
INFOID:0000000010378039
1.
CHECK OUTPUT 1 - 5 CIRCUIT FOR OPEN
1.
Turn ignition switch OFF.
2.
Disconnect 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 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 BCM 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.
Is the measurement value normal?
YES
>> Replace BCM. Refer to
BCS-132, "Removal and Installation"
.
