Troubleshooting procedure

WARNING: This page is about a different car, the 2006 Porsche Cayenne, 2005 Porsche Cayenne, 2004 Porsche Cayenne, and 2003 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

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).
