Self-Diagnostic System

NOTE: Before beginning self-diagnostics, perform TROUBLE SHOOTING .

NOTE: Many test steps refer to various connectors. To identify connectors and terminal numbers, use appropriate illustration. See CONNECTOR IDENTIFICATION DIRECTORY table under CONNECTOR IDENTIFICATION.

NOTE: After any repairs are complete, ensure all component are properly installed and all harness connectors are connected properly and repeat data link diagnostic test.

Connect New Generation Star (NGS) tester to Data Link Connector (DLC), located beneath instrument panel. Using NGS tester, perform data link diagnostics test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM in MODULE COMMUNICATIONS NETWORK - CONTINENTAL article. If NGS tester responds with CKT914, CKT915 or CKT70=ALL ECUS NO RESP/NOT EQUIP, repair module communications concern. See MODULE COMMUNICATIONS NETWORK - CONTINENTAL article. If NGS tester displays NO RESP/NOT EQUIP for Driver's Door Module (DDM), perform TEST A: NO COMMUNICATION WITH DRIVER'S DOOR MODULE under SYSTEM TESTS. If NGS tester displays NO RESP/NOT EQUIP for Driver's Seat Module (DSM), perform TEST B: NO COMMUNICATION WITH DRIVER'S SEAT MODULE under SYSTEM TESTS.

If NGS tester responds with SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Using NGS tester, perform DDM and DSM self-test. Perform appropriate test in accordance with DTC retrieved. See DRIVER'S DOOR MODULE DTC INDEX and/or DRIVER'S SEAT MODULE DTC INDEX table. Codes listed in these tables are only for testing covered in this article. For complete DTC listing, see MODULE COMMUNICATIONS NETWORK - CONTINENTAL article. If no DTCs are retrieved, repair by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
