800B PCM2 - Gateway

CAN comfort 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 modules:
- 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-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 initially ignored and should be deleted on completion of the troubleshooting.
