NOTE:
All Diagnostic Trouble Code (DTC) tests are for use with New Generation Star (NGS) scan tool. If a generic scan tool is used, ensure scan tool is certified OBD-II standard.
- To verify module communication circuits and module operation, perform DATA LINK DIAGNOSTIC TEST and ON-DEMAND SELF-TEST before retrieving codes. See MODULE COMMUNICATIONS NETWORK article.
- To retrieve Diagnostic Trouble Codes (DTCs), connect New Generation Star (NGS) scan tool to 16-pin Data Link Connector (DLC). DLC is located in center dash area. Turn ignition on.

- If diagnostic system cannot communicate with LCM, go to TEST A under SYMPTOM TESTS. After retrieving codes, perform repairs as indicated. See DTC DEFINITIONS TABLE and go to DTC TEST under DIAGNOSTIC TROUBLE CODE TESTS . If symptoms remain or if no DTCs exist, see SYMPTOM TESTS , and perform symptom test.
NOTE:
Lighting Control Module (LCM) controls more than just autolamp system. A fault in a LCM non-autolamp controlled system may effect the autolamp system.
