Yes, I think this is the case but not just because the car has CAN. CAN is used extensively throughout the automotive industry and is used primarily for comms between various control/monitoring systems, even the audio. Nearly all cars that are OBDII compliant will have a CAN bus somewhere thanks to the likes of Bosch et al supplying various system components, but the presence of CAN for these systems doesn't necessarily mean the OBD port will use it. The PT Cruiser for instance has CAN but it uses VPW for the OBD port. MB make extensive use of CAN but their OBD ports or all ISO which is why I was assuming the xfire was ISO. However I have since found out that from 2004 DC started to move from VPW to CAN for the OBD port whilst MB remains ISO. So I guess they may have switched the xfire's OBD to CAN so that DC dealers can all use the same diagnostic tools. I should be trying a CAN interface in the next couple of weeks so we shall see.
