Inspection and Verification
Since diagnosis and testing actually begins when repairs are taken on, the following procedure is recommended.
- Verify the customer concern by operating the system.
- 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 table.
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the concern is not visually evident, verify the symptom and refer to the Symptom Chart. See: Symptom Related Diagnostic Procedures
