Function
The Engine Control Module (ECM) communicates with the transmission control module via a CAN data bus.
The CAN-Bus capable control modules are connected via two data bus wires (CAN_High and CAN_Low) which are twisted together (twisted pair) and
exchange information (messages). Information missing on the data bus will be recognized as a malfunction by the Engine Control Module (ECM) and
the transmission control module.
The CAN-Bus requires a matching resistor of 66 ohms to function correctly. This matching resistor is located in the Engine Control Module (ECM).
