Initial Inspection and Diagnostic Overview

NOTE: The Passive Anti-Theft System (PATS) module must be reconfigured upon replacement of the instrument cluster. Refer to the New Generation STAR (NGS) Tester help screen on the configuration card to program.

1. Verify the customer concern by duplicating the condition.
2. Visually inspect for obvious signs of mechanical and electrical damage.

VISUAL INSPECTION CHART

Mechanical
- Ignition lock cylinder
- Encoded ignition key (PATS key)
- Use of non-encoded ignition key (key without the molded plastic head, non-PAT key)
- Use of a non-programmed encoded ignition key

Electrical

3. If the concern remains after the inspection, connect the New Generation STAR (NGS) Tester to the Data Link Connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the NGS menu. If the NGS Tester does not communicate with the vehicle:
- check that the program card is properly installed.
- check the connections to the vehicle.
- check the ignition switch position.
4. If NGS Tester still does not communicate with the vehicle, refer to the New Generation STAR Tester manual.
5. Perform the DATA LINK DIAGNOSTIC TEST. If NGS Tester responds with:
- CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Information Bus.
- NO RESP/NOT EQUIP for instrument cluster module, go to Pinpoint Test A. Test A: Communication With the Module - Instrument Cluster
- SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the instrument cluster module.
6. If the DTCs retrieved are related to the concern, go to Instrument Cluster Diagnostic Trouble Code (DTC) Index to continue diagnostics. Diagnostic Trouble Code Tests and Associated Procedures
7. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics. Symptom Related Diagnostic Procedures
