INSPECTION AND VERIFICATION
1. Verify the customer concern.
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 diagnostic tool does not power up, refer to the diagnostic tool manual.
5. Carry out the data link diagnostics test. If the diagnostic tool responds with:
- CAN, ISO, SCP or UBP circuit fault; all electronic control units no response/not equipped, refer to Information Bus (Module Communications Network).
- No response/not equipped for vehicle security module, refer to Body Control Systems (Multifunction Electronic Control Module).
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the vehicle security module.
6. If the DTCs retrieved are related to the concern, go to the Vehicle Security Module Diagnostic Trouble Code (DTC) Index to continue diagnostics. Diagnostic Trouble Code Tests and Associated Procedures
7. If DTCs are retrieved that are not found in the following Vehicle Security Module Diagnostic Trouble Code (DTC) Index, refer to the Master Vehicle Security Module Diagnostic Trouble Code (DTC) Index in Body Control Systems (Multifunction Electronic Control Module). Diagnostic Trouble Code Descriptions
8. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics. Module Controlled
