Self-Diagnostic System
CAUTION:
When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See appropriate COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.
NOTE:
Before beginning any testing, perform TROUBLE SHOOTING . Test procedures are written specifically for New Generation Star (NGS) tester. OBD-II compliant generic scan tools may not have the capability of performing all the same functions. Refer to scan tool manufacturer's instructions.
Connect New Generation Star (NGS) tester to Data Link Connector (DLC). DLC is located below center of instrument panel, right of steering wheel. Perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM in MODULE COMMUNICATIONS NETWORK
article. If NGS tester displays CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, repair module communication fault. See MODULE COMMUNICATIONS NETWORK
article. If NGS tester displays NO RESP/NOT EQUIP for Driver's Seat Module (DSM), perform TEST J: NO COMMUNICATION WITH DRIVER'S SEAT MODULE under SYSTEM TESTS.
If NGS tester displays SYSTEM PASSED for DSM, retrieve and record continuous Diagnostic Trouble Codes (DTCs). Erase continuous DTCs. Perform DSM self-test. If DTCs related to the concern are retrieved, perform appropriate test. See DRIVER'S SEAT MODULE DIAGNOSTIC TROUBLE CODE INDEX table. If no DTCs related to the fault are retrieved, repair by symptom. See SYMPTOM INDEX table under SYSTEM TESTS. For DTCs not covered in this article, see MODULE COMMUNICATIONS NETWORK
article.
