How does the ECU communicate with the VCU via CAN

[Stephen Dean]

Which VCU? If it is an OEM VCU then you will need to do some custom CAN from the M800 to the VCU. However, due to the limitations in the CAN from the M800, you would be better off using a C125 or L120 as a CAN gateway between the M800 and the VCU. This will allow for custom CAN messages to be built in the C125 or L120.
