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 B9 (Pink/Blue 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.
