Indicator Light Circuit

Verify ATS indicator light operation. See appropriate INDICATOR LIGHT under TESTING ANTI-THEFT SYSTEM COMPONENTS . Turn ignition off. Disconnect ATS ECU connector. Connect negative ohmmeter lead to ECU terminal 16 (Yellow wire) and positive lead to ground. If continuity is not present, repair open in indicator light circuit harness or connectors. If continuity is present, replace ATS ECU and retest.
