Inspection and Verification (Start Testing Here)

NOTE: The ignition switch must be cycled from OFF to RUN to enable the switched system power feature.

1. Verify the customer concern by operating the system.
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 NGS tester does not power up, refer to the New Generation STAR tester manual.
5. Carry out the DATA LINK DIAGNOSTIC TEST. If the NGS tester responds with:
^ CKT 914, CKT 915 or CKT 7O - ALLECUS NO RESP/NOT EQUIP, refer to Information Bus.
^ NO RESP/NOT EQUIP for the FEM, go to Pinpoint Test A. A: No Communication With the Front Electronic Module
^ NO RESP/NOT EQUIP for the REM, go to Pinpoint Test B. B: No Communication With the Rear Electronic Module
^ NO RESP/NOT EQUIP for the electronic IC, go to Pinpoint Test C. C: No Communication With the Instrument Cluster
^ System passed, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and carry out self test diagnostics for the FEM, REM and instrument cluster modules.

6. If the FEM DTCs retrieved are related to the concern, go to the FEM DTC Index. FEM Diagnostic Trouble Code Index
7. If the REM DTCs retrieved are related to the concern, go to the REM DTC Index. REM Diagnostic Trouble Code Index
8. If the instrument cluster DTCs retrieved are related to the concern, go to the Instrument Cluster DTC Index. Instrument Cluster Diagnostic Trouble Code Index
9. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics. Symptom Related Diagnostic Procedures
