Self-Diagnostic System

Connect New Generation Star (NGS) tester to Data Link Connector (DLC). DLC located below instrument panel. Using NGS tester, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM in MODULE COMMUNICATIONS NETWORK - EXPLORER & MOUNTAINEER article. If NGS tester displays CKT 914, CKT 915 or CKT 70=ALL MODULES NO RESP/NOT EQUIP, repair module communication concern. See MODULE COMMUNICATIONS NETWORK - EXPLORER & MOUNTAINEER article. If NGS tester displays NO RESP/NOT EQUIP for Remote Anti-Theft Personality (RAP) module, perform TEST A: NO COMMUNICATION WITH RAP MODULE  under SYSTEM TESTS. If NGS tester displays NO RESP/NOT EQUIP for Generic Electronic Module (GEM), or Central Timer Module (CTM), perform TEST I: NO COMMUNICATION WITH GEM/CTM MODULE  under SYSTEM TESTS.

If NGS tester displays SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Perform self-test for RAP module and GEM/CTM. If any DTCs are retrieved, perform appropriate test under SYSTEM TESTS in accordance with DTCs retrieved. See REMOTE ANTI-THEFT PERSONALITY MODULE DIAGNOSTIC TROUBLE CODE INDEX  and/or GENERIC ELECTRONIC MODULE/CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODE INDEX  table. Codes listed in these tables are only for testing covered in this article. For complete DTC listing, see MODULE COMMUNICATIONS NETWORK - EXPLORER & MOUNTAINEER article. If no DTCs are retrieved, repair by symptom. See SYMPTOM INDEX  under SYSTEM TESTS.
