U1000 CAN COMM CIRCUIT
U1000 CAN COMM CIRCUIT
Description
INFOID:0000000009948946
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 trans-
mits/receives data but selectively reads required data only.
