Initial Inspection - Electronic Cluster

INSPECTION AND VERIFICATION

1. Verify the customer concern by operating the system.

Visual Inspection Chart:

2. Visually inspect for obvious signs of mechanical or electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
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 diagnostic tool 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 DIAGNOSTIC 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 lighting control module (LCM), refer to Body Control Systems (Multifunction Electronic Control Module). For restraint control module (RCM), refer to Air Bag Systems. For powertrain control module (PCM), refer to Computers and Control systems.
- SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the LCM.

7. If the DTCs retrieved are related to the concern, go to the Restraint Control Module (RCM) Diagnostic Trouble Code (DTC) Index, or the Powertrain Control Module (PCM) Diagnostic Trouble Code (DTC) Index, or refer to Body Control Systems (Multifunction Electronic Control Module), Diagnostic Trouble Code (DTC) Index to continue diagnostics.

8. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics. Diagnosis By Symptom - Electronic Cluster
