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.
