The CTM-ONE can draw power from the vehicle CAN Bus (OBDII/J1939). Connect the 8 Pin terminal to the
CAN Bus port on the CTM-ONE and connect the other end to the vehicle diagnostic port.

The CAN interface is used primarily to interface to Vehicle sub-systems that support CAN communications.
This includes all small and light duty vehicles manufactured in 2008 and later (ISO15765-4) and heavy-duty
vehicles that support J1939.
An accessory OBDII or J1939 Cable is required to interface to a vehicle Engine Control Unit (ECU). The CTM-
ONE can be powered from the CAN port, so no other cabling is required if the vehicle supports either OBDII
or J1939 communications.
The CTM-ONE supports both Medium and High-speed CAN interfaces as well as Single Wire CAN.
