Door Unlock Detection Switch

Remove door trim and door lock assembly. Locate and disconnect 4-pin door lock motor and unlock detection switch connector. Check for continuity between 4-pin connector terminals No. 1 (left side is Blue/White wire, right side is Green/Black wire) and No. 3 (White/Black wire). There should be continuity when door lock is in unlocked position. There should be no continuity when door lock is in locked position. If continuity is not as specified, replace door unlock detection switch. If continuity is as specified, inspect harness and connectors between door unlock detection switch and ATS ECU.
