Initial Inspection and Diagnostic Overview

INSPECTION AND VERIFICATION

NOTE: The rear electronics module (REM), front electronics module (FEM), and the remote keyless entry (RKE) module must be reconfigured upon installation, Refer to Module Communications Network (Information Bus).

1. Verify the customer concern by operating the system.

Visual Inspection Chart:

2. Visually inspect for obvious signs of mechanical and 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 FEM, refer to Multifunction Electronic Control Module (General Module).
- NO RESP/NOT EQUIP for REM, refer to Multifunction Electronic Control Module (General Module).
- NO RESP/NOT EQUIP for RKE, refer to Multifunction Electronic Control Module (General Module).
- SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the FEM, REM, and RKE.

7. If the DTCs retrieved are related to the concern, go to the FEM Diagnostic Trouble Code (DTC) Index, REM Diagnostic Trouble Code (DTC) Index, RKE Diagnostic Trouble Code (DTC) Index to continue diagnostics. FEM Diagnostic Trouble Code (DTC) Index REM Diagnostic Trouble Code (DTC) Index RKE Diagnostic Trouble Code (DTC) Index
8. If DTCs are retrieved that are not found in the FEM Diagnostic Trouble Code (DTC) Index, REM Diagnostic Trouble Code (DTC) Index, RKE Diagnostic Trouble Code (DTC) Index, refer to the master Diagnostic Trouble Code (DTC) Index in Multifunction Electronic Control Module (General Module).
9. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics. Symptom Related Diagnostic Procedures
