What is CAN and
why is it important?
_____CAN stands for
Controller Area Network. CAN is a new means of communicating with
the car for diagnostics ed 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 ignaling.
CAN is considerably faster than ISO-9141 (500 kpbs vs. 10.4 kbps).
Both new hardware and new software are equired in order to communicate
with cars using CAN for diagnostics.
