TROUBLE SHOOTING

Before performing individual component tests and system test, check the following for possible cause of system malfunction. Repair any problems as necessary and operate seat to see if malfunction is repaired. If malfunction still exists, go to SYSTEM TESTING.

  1. Blown fuses or faulty circuit breakers.
  2. Loose or corroded connectors.
  3. Damaged wiring.
  4. Damaged mirror assembly.
  5. Faulty switches.

SYSTEM TESTING

Note. Before beginning system testing, perform TROUBLE SHOOTING.

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.

Connect New Generation Star (NGS) tester to data link connector. Perform DATALINK DIAGNOSTIC TEST. See MODULE COMMUNICATIONS NETWORK. 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 Seat Module (DSM) or exits self-test and returns to normal operating state, go to TEST B under DIAGNOSTIC TESTS. If NGS tester responds with, NO RESPONSE/NOT EQUIPPED for Driver Door Module (DDM) or exits self-test and returns to normal operating state, go to TEST A under DIAGNOSTIC TESTS.

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