Canbus is a multiplexed wiring system used to connect intelligent devices such as Electronic Control Units (ECU’s) on vehicles, allowing data to be transferred in a low-cost and reliable manner. CAN means ‘Controller Area Network’ and was developed by Bosch in 1980. Most new vehicles use this system and it is becoming increasingly difficult to install after-market products without using a CAN Bus Interface.

Why is this system used?

The reasons for the vehicle manufacturers using CAN Bus are:-

(a)  Significant reduction in wiring leading to:-

(i) Significant reduction in manufacturing cost and hence retail cost.

(ii) Reduction in weight resulting in improved fuel consumption.

(b) Reduced number of interconnections hence improving reliability.

So considering that more and more modern cars are reliant uopn this system, it is useful to get the right HID canbus kit.
