Self-Diagnostic System
- The remote keyless entry system utilizes a self-diagnostic system which may store a Diagnostic Trouble Code (DTC) if a problem exists in the system. DTCs may be retrieved using NGS tester and Data Link Connector (DLC) for diagnosis of system.
- Connect NGS tester to DLC located below instrument panel. Using NGS tester, perform DATA LINK DIAGNOSTIC TEST. If NGS tester displays CKT 914, CKT 915 or CKT 70=ALL MODULES NO RESP/NOT EQUIP, see appropriate MODULE COMMUNICATIONS NETWORK article to diagnose network concern. If NGS tester displays NO RESP/NOT EQUIP for Remote Anti-Theft Personality Module (RAP), perform TEST A: NO COMMUNICATION WITH RAP MODULE under SYSTEM TESTS.
- If NGS tester displays SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Perform self-test for RAP using NGS tester. If RAP DTCs are retrieved, see RAP MODULE DTC INDEX table to continue diagnosis. If no DTCs are retrieved, perform appropriate symptom test under SYSTEM TESTS .
