Initial Inspection - Instrument Panel Illumination

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







VISUAL INSPECTION CHART

3. If the concern remains after the inspection, connect the New Generation STAR (NGS) Tester to the data link connector located beneath the instrument panel and select the vehicle to be tested from the NGS menu. If the NGS does not communicate with the vehicle:
^ check that the program card is correctly installed.
^ check the connections to the vehicle.
^ check the ignition switch position.

4. If the NGS still does not communicate with the vehicle, refer to the New Generation STAR Tester.
5. Carry out the DATA LINK DIAGNOSTIC TEST. If the NGS responds with:
^ CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Module Communications Network (Information Bus).
^ NO RESP/NOT EQUIP for Front Electronic Module (FEM), go to Pinpoint Test A. Test A: No Communication With the Front Electronic Module
^ NO RESP/NOT EQUIP for instrument cluster, go to Pinpoint Test B. Test B: No Communication With the Instrument Cluster Module
^ SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the ICM or FEM.

6. If the DTCs retrieved are related to the concern, go to the
Instrument Cluster DTC Index Instrument Cluster Diagnostic Trouble Code (DTC) Index
or FEM DTC Index to continue diagnostics. Front Electronic Module Diagnostic Trouble Code (DTC) Index
7. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics. Diagnosis By Symptom - Instrument Panel Illumination

NOTE: The instrument cluster and FEM must be reconfigured upon replacement. Refer to Module Communications Network (Information Bus).
