800B PCM2 - Gateway

CAN Signal Fault, Instrument Cluster

Diagnostic conditions
- Ignition on
- PCM2 on

Possible cause of fault
- Instrument cluster control module has a fault memory entry

NOTE:
CAN comfort is connected to the following control units:
- PCM2 as of model year 2003
- Instrument cluster
- Air-conditioning system control module
- Radio

NOTE: The plug connections of control modules connected to CAN comfort are disconnected during troubleshooting. This causes additional CAN-relevant fault codes, e.g. "8005 Instrument cluster" and "800A Air conditioning" to be stored in the fault memory of the PCM2. These fault codes should be ignored initially and must be deleted when troubleshooting is complete.
