NOTE:
- Terminal resistors built into the ECM and VDCCM&H/U stabilize traffic on the bus, and enables signals distinction from the voltage difference between the two bus lines (CAN_High and CAN_Low). These bus lines are called the main lines. Other units are connected in parallel to the main lines. These wires are called branch lines.
- If one bus line of the main lines becomes open, this is detected as an error and communication becomes no longer possible.
- If one bus line of a pair of branch lines becomes open, communication with the unit connected to the branch line becomes no longer possible, however, communication with other units remain intact. (The error will be displayed.)
