CAN bus

A Controller Area Network is a serial protocol for data transfer between electronic components in a car, without the intervention of a host computer. The CAN bus controls the power consumption in the car via data traffic. Data traffic is used, so that the priority between the subsystems connected to the CAN bus (eg engine management, temperature control systems, ABS and ESP) is controlled via a protocol. Thanks to CAN bus, the entire electronic control of all electricity to, for example, a door is controlled via two thin wires instead of a whole wiring harness.
