Driver's & Passenger's Door Key Lock Switch Circuit

Turn ignition off and disconnect ATS ECU connector. Lock driver's or passenger's door with key. Ensure continuity exists between ground and ATS ECU connector terminal A14 (with power door locks, White/Green wire) or No. 11 (without power door locks, White/Green wire). If continuity is not present, repair open in lock switch circuit. If continuity is present, unlock driver's or passenger's door and ensure continuity is not present. If continuity is not present, go to next step. If continuity is present, repair short in lock switch circuit.
