CVT RE0F08B

U1010 CONTROL UNIT (CAN)

Description

Real time communication is performed between each control unit such as TCM, ECM, combination meter, or others. Information is shared and linked between other control units. Each system is optimally controlled according to driving conditions of the vehicle.
In CAN (Controller Area Network) communication, 2 control units are connected via 2 communication lines (CAN-H and CAN-L) allowing a high rate of information transmission via less wiring. Each control unit transmits/receives data but selectively reads required data only.
