Self-Diagnostic System
NOTE:
All diagnostic tests are written specifically for New Generation Star (NGS) or Worldwide Diagnostic System (WDS) scan tool. Most generic scan tools should be able to perform all test procedures.
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 MODULE COMMUNICATIONS NETWORK - EXPLORER & MOUNTAINEER article. If scan tool responds with CKT70, CKT914 OR CKT915, repair module communications concern. See
MODULE COMMUNICATIONS NETWORK - EXPLORER & MOUNTAINEER 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 (DTCs). 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 DIAGNOSTIC TROUBLE CODE INDEX
table.
If no DTCs are retrieved though PAM self-diagnostics, repair by symptom. See SYMPTOM INDEX
table under SYSTEM TESTS.
