Installation instructions for the Speedometer Interface
CAN (Control Area Network Interface)
The vehicle speed information from the CAN network is interfaced to the external world over the OBD2 (On
Board Diagnostics) port. The OBD2 port in most cases is found under the steering column of the vehicle. The 16-
pin OBD2 connector taps into the OBD2 port of the vehicle and the vehicle speed information is send to the radar.
In MPH radars the vehicle speed is sensed over the CAN network for the Ford and GM model vehicles only.
