Hello , thanks for your question in the autoaid Community.
Your described fault Code means: CAN-Bus
This code comes in every other ECUs, so i think there is a problem from your Brake ECU to the Can Bus.
Maybe the wirings are faulty, or the BUS is faulty.
Sometimes the ECU is faulty.
So check at first the wirings and fuses from this ECU.
After this check the CAN Bus and look for the final resistances of the CAN Bus. For this you have to measure the resistance from CAN high to CAN low.
But i think there is a problem with the wirings or the ecu.
