Inspection and Verification

NOTE: The Front Electronic Module (FEM), and the Rear Electronic Module (REM) must be reconfigured upon replacement. Refer to the NGS Tester help screen on the configuration card to program the daytime running lamps and headlamps on with wipers.

1. Verify the customer concern by operating the perimeter anti-theft system.
2. Visually inspect for obvious signs of mechanical and electrical damage.

3. 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 Tester menu. If the NGS Tester does not communicate with the vehicle:
^ check that the program card is properly installed.
^ check the connections LO the vehicle.
^ check the ignition switch position.

4 If the NGS still does not communicate with the vehicle, refer to the NGS Tester manual.
5. Perform the DATA LINK DIAGNOSTIC TEST using the NGS tester. If the NGS responds with:
^ CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Information Bus.
^ NO RESP/NOT EQUIP for FEM, go to Pinpoint Test A. A: No Communication With Front Electronic Module
^ NO RESP/NOT EQUIP for Rear Electronic Module (REM), go to Pinpoint Test B. B: No Communication With the Module-Rear Electronic Module
^ SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the FEM or REM.

6. If the DTCs retrieved are related to the concern, go to FEM DTC Index FEM Diagnostic Trouble Code Index
or REM DTC Index to continue diagnostics. REM Diagnostic Trouble Code Index
7. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics. Diagnosis by Symptom
