2 Visually inspect for obvious signs of damage 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 diagnostic trouble codes index
