The
Haltech CAN Network
The Haltech CAN network allows for simple and effective expansion in ECU capability
and functionality without having to go to the trouble of wiring in a whole new computer.
Expansion is made possible by the addition of multiple expansion devices that
communicate to the main ECU via a Control Area Network (CAN).
Installation time and costs are kept to a minimum as all expansion devices are
powered up from the main ECU via the pre-terminated connection cable that comes
with each expansion device.
Simply connect the device directly to the 8 pin CAN connector on the rear of the ECU
or connect using an optional Haltech CAN Hub (order as part # HT059990) if multiple
expansion devices are required).
Each expansion device is pre-programmed with a unique ID code which allows it to
be recognised on the network and work correctly first time every time.
For current available expansion devices please go to our website at
