What is CAN BUS?
CAN BUS (Controller Area Network) is a serial communications network that allows most of the
vehicle modules (ECU’s) to communicate with each other using data. On old vehicle’s the four
control switches for the electric windows in the drivers door would have at least 2 wires from each
switch going to each door window on the vehicle. On new vehicles with CAN bus only two wires are
required to come from the drivers door to control all the electric windows on the vehicle. This is
achieved by having small modules inside each door that interprets the CAN data on these two
wires. These modules not only control the electric windows they also control other equipment like,
central locking, interior/exterior lighting, electric mirrors, electric seats, etc. The Laserline 6 series
alarms are capable of reading some of the CAN bus data to interpret when doors are open/closed,
