Troubleshooting procedure
Troubleshooting can only be performed when the fault is present. In other words, specific troubleshooting can only be performed in accordance with instructions (given under Diagnosis/troubleshooting for each fault code) if the entry has the status 'present' in the fault memory.
If the fault is currently 'not present', please check the following
- Diagnosis conditions are met; if necessary perform a short test or test drive
- All plug connections and ground points of the affected current path are OK
- Set all wiring harnesses of the affected current path to a state that corresponds to driving by pulling and shaking them (loose contact)
Diagnostic conditions
| IMPORTANT | Always connect a suitable battery charging device to the vehicle electrical system battery or to the designated jump-start terminal before starting diagnosis. All unnecessary loads must also be switched off. |
Note. The fault can only be identified if the requirements listed under 'Diagnostic conditions' are met. For this reason, the specified procedure must be observed after a fault is repaired
- Erase fault memory.
- Satisfy the requirements listed under 'Diagnostic conditions'.
- Read out fault memory again.
