Self-Diagnostic System

WARNING: This page is about a different car, the 2002 Lincoln Blackwood. However, it is still accessible from the selected car via links, so may be relevant.

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

Connect New Generation Star (NGS) tester to Data Link Connector (DLC). DLC is located below center of instrument panel, right of steering wheel. Using NGS tester, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM in MODULE COMMUNICATIONS NETWORK - BLACKWOOD article. If NGS tester displays CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, repair module communication problem. See MODULE COMMUNICATIONS NETWORK - BLACKWOOD 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 displays SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Using NGS tester, perform GEM self-test. If GEM DTCs are retrieved, perform appropriate test. See GENERIC ELECTRONIC MODULE DIAGNOSTIC TROUBLE CODE DEFINITIONS table. If no DTCs are retrieved, perform appropriate test based on symptom. See SYMPTOM INDEX table under SYSTEM TESTS. For GEM DTCs not covered in this article, see MODULE COMMUNICATIONS NETWORK - BLACKWOOD article.
