NOTE:
  • With CAN, one twisted-pair cable (2 wires) manages transmission of all data. (serial communication)
  • The main wire runs between the terminal resistor on the ECM and that on the ABSCM or vehicle dynamics control (VDC) CM&H/U. Other units are connected, in parallel, to the main wire via branch wires.
