2. Visually inspect for obvious signs of mechanical or electrical damage.
3. Verify the following systems are working correctly:
- charging system
- fuel system
- cooling system
- safety belt warning chime (GEM) system
- turn signal system
- headlamp system
- anti-theft system

If the system(s) are not working correctly, refer to the appropriate vehicle system.

4. If the concern remains after the inspection, connect the diagnostic tool to the Data Link Connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the menu. If the diagnostic tool 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 diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
6. Carry out the DATA LINK DIAGNOSTICS TEST. If the diagnostic tool responds with:
- CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Module Communications Network (Information Bus).
- NO RESP/NOT EQUIP for Generic Electronic Module (GEM), refer to Multifunction Electronic Control Module (General Module).
- SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the GEM.
7. If the DTCs retrieved are related to the concern, go to the GEM Diagnostic Trouble Code (DTC) Index to continue diagnostics. Trouble Code Diagnostic Charts - Instrument Cluster
8. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics. Diagnosis By Symptom - Instrument Cluster
