CAN2.0B Bus
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 CAN cable + OBDII or J1939 “Y Cable” is required to interface to a vehicle Engine Control Unit
(ECU).
