Using New Generation Star (NGS) Tester

NOTE: All diagnostic tests are written specifically for New Generation Star (NGS) tester. Most generic scan tools should be able to perform all test procedures.

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

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