184000526 - K47 MILOMETER/TRIP METER FLASHING

The Engine Management Node sends the message via the C-CAN to the Body Computer which makes it available, via the B-CAN, to the Instrument Panel Node.
Any faults in the C-CAN light up the control unit warning lights which communicate on this network. The CAN information check is designed precisely for this purpose
