Initial Inspection - Information and Message Center

1. Verify the customer concern by operating the instrument cluster and message center to duplicate the condition by observing the indicators, warning displays, and gauges to determine if they are operating correctly with the ignition switch:
^ in RUN with the engine off
^ in START before the ignition switch is released
^ in RUN with the engine running
2. Visually inspect for obvious signs of mechanical and electrical damage.







VISUAL INSPECTION CHART

3. If the inspection reveals obvious concern(s) that can be readily identified, repair as necessary.
4. 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.
5. If the NGS still does not communicate with the vehicle, refer to the New Generation STAR Tester.
6. 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 instrument cluster or message center, go to Pinpoint Test A. Test A: No Communication With the Instrument Cluster Module/Message Center Module
^ NO RESP/NOT EQUIP for FEM, go to Pinpoint Test B. Test B: No Communication With the Front Electronic Module
^ NO RESP/NOT EQUIP for REM, go to Pinpoint Test C. Test C: No Communication With Rear Electronic Module
^ SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the instrument cluster.
7. If the DTCs retrieved are related to the concern, go to the
Message Center Module DTC Index, Message Center Module Diagnostic Trouble Code (DTC) Index
Instrument Cluster DTC Index, Instrument Cluster Diagnostic Trouble Code (DTC) Index
FEM DTC Index, Front Electronic Module Diagnostic Trouble Code (DTC) Index
REM DTC Index Rear Electronic Module Diagnostic Trouble Code (DTC) Index
or RESCU DTC Index to continue diagnostics. RESCU Diagnostic Trouble Code (DTC) Index
8. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics. Diagnosis By Symptom - Information and Message Center

NOTE: The IC, MC, REM, and FEM must be reconfigured upon replacement. Refer to Module Communications Network (Information Bus).
