Left Front Door Unlock Detection Switch Circuit

Verify door unlock detection switch operation. See appropriate DOOR UNLOCK DETECTION SWITCH under TESTING ANTI-THEFT SYSTEM COMPONENTS . Turn ignition off and disconnect ATS ECU connector. Close and unlock left front door. Ensure continuity exists between ground and ATS ECU connector terminal A11 (with power locks, Pink/Blue wire) or No. 3 (without power locks, Pink/Blue wire). If continuity is present, go to next step. If continuity is not present, repair open in harness or connectors as necessary.
