  1. Precautions for can communication

  1. Can communication lines are used to receive information from the skid control ecu and the ecm, and to transmit warnings to the combination meter.

    When there are any problems in the can communication lines, dtcs of the can communication line are output.

  2. Perform troubleshooting for the communication line problems when the can communication dtcs are output. Be sure to start troubleshooting on the electronic power steering system after confirming that the can communication system is normal.
  3. Since the can communication line has its own length and route, it cannot be repaired temporarily with a bypass wire, etc.
