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 BCM OUTPUT VOLTAGE
1.
Connect BCM connector.
2.
Check voltage between BCM harness connector and ground.
Is the measurement value normal?
