800A PCM2 - Gateway

CAN Comfort Timeout, Air-Conditioning System

Diagnostic conditions
- Ignition on
- PCM2 on

Possible cause of fault
- CAN comfort (high) - open circuit
- CAN comfort (low) - open circuit

NOTE:
CAN comfort is connected to the following control modules:
- 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.
