- CAN comfort (high) - open circuit
- CAN comfort (low) - open circuit
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-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 ignored initially and must be deleted when troubleshooting is complete.
