Self-Diagnostic System

NOTE: The remote keyless entry system utilizes a self-diagnostic system which stores a Diagnostic Trouble Code (DTC) if a problem exists in the system. DTCs may be retrieved using New Generation Star (NGS) tester connected to Data Link Connector (DLC).

Connect New Generation Star (NGS) tester to Data Link Connector (DLC). DLC is located below steering column. Using NGS tester, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM in MODULE COMMUNICATIONS NETWORK - RANGER article. If NGS tester responds with CKT914, CKT915 or CKT70=ALL ECUS NO RESP/NOT EQUIP, repair module communications concern. See MODULE COMMUNICATIONS NETWORK - RANGER article. If NGS tester displays NO RESP/NOT EQUIP for Central Security Module (CSM), perform TEST A: NO COMMUNICATION WITH CENTRAL SECURITY MODULE under SYSTEM TESTS.

If NGS tester responds with SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Using NGS tester, perform CSM self-test. Perform appropriate test in accordance with DTC retrieved. See CENTRAL SECURITY MODULE DIAGNOSTIC TROUBLE CODE INDEX table. Codes listed in this table are only for tests covered in this article. For complete DTC listing, see MODULE COMMUNICATIONS NETWORK - RANGER article. If no DTCs are retrieved, repair by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
