Self-Diagnostic System: Notes

NOTE: Before performing self-diagnostics, See TROUBLE SHOOTING  .
NOTE: All Diagnostic Trouble Code (DTC) tests are for use with New Generation Star (NGS) tester. If a generic scan tool is used, ensure scan tool is certified OBD-II standard.

Connect NGS tester to data link connector. Perform DATA LINK DIAGNOSTIC TEST. See appropriate MODULE COMMUNICATIONS NETWORK article. If NGS tester responds with CKT 914 or CKT 915=ALL MODULES NO RESPONSE/NOT EQUIPPED, diagnose network concern. See appropriate MODULE COMMUNICATIONS NETWORK article. If NGS tester responds with, NO RESPONSE/NOT EQUIPPED for Generic Electronic Module (GEM), go to TEST A: NO COMMUNICATION WITH GENERIC ELECTRONIC MODULE (GEM)  under SYSTEM TESTS. If NGS tester responds with, NO RESPONSE/NOT EQUIPPED for Remote Anti-Theft Personality (RAP) module, go to TEST B: NO COMMUNICATION WITH REMOTE ANTI-THEFT PERSONALITY (RAP) MODULE  under SYSTEM TESTS.

If NGS tester responds with SYSTEM PASSED for all modules, retrieve DTCs for all modules. If any DTCs exist, perform appropriate test under SYSTEM TESTS. See appropriate DTC INDEX table. If no DTCs were retrieved, repair system by symptom. See SYMPTOM REFERENCE  table and perform appropriate test under SYSTEM TESTS.
