Level control: Introduction: Notes
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.
NOTE:
The basic equipment of the Cayenne includes the level control module. The PASM function (Porsche Active Suspension Management) can also be integrated into the level control module. This enhanced control module is known as the level control module with PASM. The assembly and service number are identical for both control modules. The following troubleshooting diagnosis can be applied to both control module types. To simplify matters, the control module is always referred to as the level control module in the following description. An independent check must therefore be made to ascertain which type of control module is installed. The difference between the two types of control module, from the point of view of diagnostics, is that the fault codes 0142, 0143, 0144 and 0145 cannot occur for the level control module. In addition, various menu and selection functions in the 9588 Porsche System Tester II are not used.
NOTE:
The following troubleshooting diagnosis has been geared only towards left-hand drive vehicles and describes only these types of vehicles. In some cases, specified plugs and sockets may be assigned differently in right-hand drive vehicles, which can lead to incorrect interpretations during troubleshooting and to unforeseen accidents. Therefore, no work should be performed on right-hand drive vehicles without the correct wiring diagram and troubleshooting diagnosis description.
