Inspection & Verification

Since diagnosis and testing actually begins when repairs are taken on, the following procedure is recommended.

1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical damage or electrical damage. If the concern cannot be reproduced, carry out a road test and/or visual check with the aid of the following illustration.

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 concern is not visually evident, verify the symptom and refer to SYMPTOM TROUBLESHOOTING CHART - ENGINE  .
