Self-Diagnostic System

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 - SABLE & TAURUS article. If NGS tester responds with CKT914, CKT915 or CKT70=ALL ECUS NO RESP/NOT EQUIP, repair module communications concern. See MODULE COMMUNICATIONS NETWORK - SABLE & TAURUS article. If NGS tester displays NO RESP/NOT EQUIP for Generic Electronic Module (GEM), perform TEST A: NO COMMUNICATION WITH GENERIC ELECTRONIC MODULE under SYSTEM TESTS.

If NGS tester responds with SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Using NGS tester, perform GEM self-test. Perform appropriate test in accordance with DTC retrieved. See GENERIC ELECTRONIC MODULE DTC INDEX table. Codes listed in this table are only for testing covered in this article. For complete DTC listing, see MODULE COMMUNICATIONS NETWORK - SABLE & TAURUS article. If no DTCs are retrieved, repair by symptom. See SYMPTOM CHART table under SYSTEM TESTS.
