Self-Diagnostic System

NOTE: All diagnostic tests are written specifically for Worldwide Diagnostic System (WDS) or New Generation Star (NGS) scan tool. Most generic scan tools should be able to perform all test procedures.
NOTE: Refer to appropriate SELF-DIAGNOSTIC article in ENGINE PERFORMANCE for further instructions on retrieving and clearing DTCs.

Connect scan tool to Data Link Connector (DLC). Using scan tool, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM in appropriate MODULE COMMUNICATIONS NETWORK article. If scan tool displays CKT70=ALL ECUS NO RESP/NOT EQUIP, CKT914=ALL ECUS NO RESP/NOT EQUIP or CKT915=ALL ECUS NO RESP/NOT EQUIP, repair module communications problem. See appropriate MODULE COMMUNICATIONS NETWORK article. If scan tool displays NO RESP/NOT EQUIP FOR PAM, perform TEST A: NO COMMUNICATION WITH PARKING AID MODULE  under SYSTEM TESTS.

If scan tool responds with SYSTEM PASSED, retrieve and record continuous Diagnostic Trouble Codes (DTC). Erase continuous DTCs. Using scan tool, perform PAM self-test. If DTCs are retrieved, perform corresponding test(s) under SYSTEM TESTS. See PARKING AID MODULE DTC INDEX  table. If no DTCs are retrieved through PAM self-test, repair by symptom. Perform appropriate test(s) under SYSTEM TESTS. See SYMPTOM INDEX  table under SYSTEM TESTS.
