CHECK INPUT 1 - 5 SYSTEM CIRCUIT FOR OPEN 1. Turn ignition switch OFF. 2. Disconnect BCM and combination switch. 3. Check continuity between BCM harness connector and combi- Does continuity exist? YES >> GO TO 2 NO >> Repair or replace harness. 2. CHECK INPUT 1 - 5 SYSTEM CIRCUIT FOR SHORT Check for continuity between BCM harness connector and ground. Does continuity exist? YES >> Repair or replace harness. NO >> GO TO 3 3. CHECK BCM OUTPUT VOLTAGE 1. Connect BCM. 2. Turn ignition switch ON. 3. Check voltage between BCM harness connector and ground. Is the measurement value normal?
