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 .
