Components DescriptionAKS006YD
CAN CommunicationAKS00815
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tric control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). 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.
CAN COMMUNICATION UNIT
Refer to LAN-6, "CAN Communication Unit" .
Switch OperationAKS006YF
The system is operated by a master ON/OFF switch and four control switches, all mounted on the steering
wheel.

signals and CAN communication data, then controls vehicle distance.
ICC sensor××Irradiate laser beam, and receives reflected laser beam to measure dis-
tance from preceding vehicle.
ECM××Transmits throttle position signal and ICC steering switch signal to ICC unit.
ABS actuator and electric
unit (control unit)×××Transmits wheel speed signal to ICC unit.
Brake pressure sensor××Detects fluid pressure in master cylinder.
Brake booster××Adjusts brake fluid pressure, based on command from ICC unit.
