What is CAN and why is it important?


	Soft Interface

CAN stands for Controller Area Network. CAN is a new means of communicating with the car for diagnostics used by the latest generations of VW, Audi, SEAT, and Skoda vehicles. Unlike the older ISO9141 system, which used a single K-line for diagnostic communications, the new CAN-Bus system uses a twisted pair of wires with differential signaling. CAN is considerably faster than ISO-9141 (500 kpbs vs. 10.4 kbps). Both new hardware and new software are required in order to communicate with cars using CAN for diagnostics.
