If the TCM is contacted, the diagnostic instrument will first call DICE and request diagnostics communication with the TCM. DTC sends the diagnostic
instrument's request to the I-bus and the MIU then sends the diagnostics request to the P-bus and TCM, This means that the DICE and MIU must both be
supplied with current (awake) to enable contact with the TCM to be made.
Diagnostics
If none of the bus systems can be contacted then the fault must be either in the car or in the diagnostic tool.
If the diagnostic tool can make contact with any of the systems concerned in another car, the fault will be in the car.
DICE and all bus Systems except EDC 15
