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).
