Originally developed by Bosch in the 1980s, CAN (Control Area Network) is a robust system which enables high-speed communications and signals between different systems on a vehicle without the need for complex wiring. An increasing number of manufacturers utilise CAN Bus for managing systems such as lighting, heating, instrumentation, suspension, braking and engine control with separate ECUs which can be linked with a single pair of wires, thus drastically cutting down the total amount of wiring required within a vehicle.
