Verify door unlock detection switch operation. See appropriate DOOR UNLOCK DETECTION SWITCH under COMPONENT TESTS . Turn ignition off and disconnect ATS ECU connector. Close and unlock rear door. Ensure continuity exists between ground and ATS ECU connector terminal A2 (Yellow wire). If continuity is not present, repair open in harness or connector as necessary. If continuity is present, replace ATS ECU and retest.
