Description
CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independently). In CAN communication, control units are connected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

Vehicle Dynamic Control (VDC) off switch
The vehicle should be driven with the VDC system
on for most driving conditions.
If the vehicle is stuck in mud or snow, the VDC
system reduces the engine output to reduce
wheel spin. The engine speed will be reduced
even if the accelerator is depressed to the floor. If
