Inspection & 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 illustration.
