Permanent bus faults

All communication between Tech 2 and systems connected to a bus is via DICE. Irrespective of which system is contacted, Tech 2 will first check with the aid of the DICE that all systems in the car connected to a bus are awake and in communication. If any control module connected to a bus is missing, this will be displayed on Tech 2. Thus, all control modules connected to a bus are communicating correctly if Tech 2 does not give a warning.
