Inspection and verification
WARNING: Risk of accident. The parking brake must be applied. Switch the gearbox in the block with the driving axle to the position "R". Failure to follow these instructions may result in injury.
Because Fault diagnosis starts from the moment the vehicle is received for repair, we recommend the following procedure:
1. Check the legitimacy of the customer's complaint by activating the system.
2. Visually inspect for obvious signs of mechanical or electrical damage.
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 of the problem is not visually obvious, check the symptom and refer to the Symptom Chart.
