Possible cause of fault
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.
- Open circuit in CAN Bus Comfort (high)
- Open circuit in CAN Bus Comfort (low)
The CAN comfort is connected to the following control units:
PCM2 as of model year 2003
Instrument cluster
Air-conditioning control unit
Radio
NOTE:
The plug connections of control modules connected to CAN comfort are disconnected during troubleshooting. This causes additional CAN-related fault codes, for example, 9110 DME control module to be stored in the fault memory of the instrument cluster. These fault codes should be initially ignored and should be deleted on completion of the troubleshooting.
