VISUAL INSPECTION CHART
3. Verify systems are working correctly:
^ Charging.
^ Fuel.
^ Cooling.
^ Safety belt warning chime (GEM/CTM).

^ check that the program card is correctly installed.
^ check the connections to the vehicle.
^ check the ignition switch position.
5. If the scan tool still does not communicate with the vehicle, refer to the scan tool manual.
6. Carry out the DATA LINK DIAGNOSTIC TEST. If the scan tool responds with:
^ CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Module Communications Networks (Information Bus).
^ NO RESP/NOT EQUIP for Generic Electronic Module (GEM)/Central Timer Module (CTM), go to Pinpoint Test V. Test V: No Communication With the Module - GEM/CTM
^ SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs, and carry out self-test diagnostics for the GEM/CTM.
7. If the DTCs retrieved are related to the concern, go to the GEM/CTM Diagnostic Trouble Code (DTC) Index to continue diagnostics. GEM/CTM 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 - Instrument Cluster
