Inspection and Verification

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

2. Visually inspect for obvious signs of mechanical damage. If the concern cannot be reproduced, carry out a road test and/or visual check with the aid of the following table.Visual Inspection Chart
