Inspection and verification
1. Check the customer's complaint.
2. Perform a visual check for obvious signs of mechanical or electrical damage.
Visual Inspection Table
Electrical Factors
- Fuse (And)
- Wiring harness
- electrical connector (s)
3. If an obvious cause of the problem you identified or described by the client is found, eliminate it before proceeding to further actions (if possible).
4. If the cause is not visually obvious, check the symptom and refer to the Symptom Chart.
