Initial Inspection and Diagnostic Overview

Inspection and Verification
1 Verify the customer concern.
2 Visually inspect for obvious signs of damage, water ingress and system integrity.





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 cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
