5.2 In Vehicle Installation
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.
5.3 CAN2.0B Bus
Molex Micro-Fit 3.0™ connector #:
Crimp Terminals 20-24 AWG
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.
