System Testing

NOTE: A New Generation Star (NGS) tester is required to test the power mirror system. If NGS tester does not communicate with vehicle, refer to NGS tester manual. Before beginning system testing, perform TROUBLE SHOOTING.

Connect New Generation Star (NGS) tester to data link connector. Perform DATALINK DIAGNOSTIC TEST. See MODULE COMMUNICATIONS NETWORK article. If NGS tester responds with CKT 914 and CKT 915=ALL MODULES NO RESPONSE/NOT EQUIPPED, diagnose network concern. See MODULE COMMUNICATIONS NETWORK article. If NGS tester responds with, NO RESPONSE/NOT EQUIPPED for Driver's Seat Module (DSM), go to TEST E: NO COMMUNICATION WITH DRIVER'S SEAT MODULE (DSM) under DTC TESTS. If NGS tester responds with, NO RESPONSE/NOT EQUIPPED for Driver's Door Module (DDM), go to TEST D: NO COMMUNICATION WITH DRIVER'S DOOR MODULE (DDM) under DTC TESTS.

If NGS tester responds with SYSTEM PASSED for all modules, retrieve DTCs for all modules. If any DTCs exist, perform appropriate test. See appropriate DTC DEFINITIONS table. If no DTCs were retrieved, repair system by symptom. See SYMPTOM CHART table and perform appropriate test.
