The diagnostic connector itself is not a controller. Instead, the IFAK cable that leads to the laptop computer contains the controller that will make contact with the CANbus system when plugged into the diagnostic connector.

The optional Electronic Climate Control has an independent control system that does not communicate through CANbus wires 900 and 901. The CANbus inverse wire and data wire are twisted together to reduce sensitivity to electromagnetic interference. For the same purpose there are termination resistors at the extreme ends of the string of controllers. The CANbus system will not function if both 120 Ohm resistors are faulty or disconnected.
