SYSTEM DESCRIPTION
Refer to LAN-5, "CAN COMMUNICATION" .
Switch OperationEKS00BLK
The system is operated by a master ON/OFF switch and four control switches, all mounted on the steering
wheel.
ComponentVehicle-to-vehicle
distance control
modeConventional
(fixed speed)
cruise control
modeBrake assist
(with preview
brake)Description
ICC unit×××Controls vehicle speed through ECM via CAN
communication.
ICC sensor××Irradiate laser beam, and receives reflected
laser beam to measure distance from preceding
vehicle.
ECM×××Transmits throttle position signal and ICC steer-
ing switch signal to ICC unit.
ABS actuator and electric
unit (control unit)×××Transmits wheel speed signal to ICC unit.
Operates brake booster based on CAN commu-
nication.
Brake pressure sensor××Detects fluid pressure in master cylinder.
Brake booster××Adjusts brake fluid pressure based on command
from ABS actuator and electric unit (control
unit).
BCM×Transmit front wiper request signal to ICC unit.
TCM××Transmits gear position signal and output shaft
revolution signal to ICC unit.
No. Switch name Description
1 ACCEL/RES switch Resumes set speed or increases speed incrementally.
2 COAST/SET switch Sets desired cruise speed, reduces speed incrementally.
3 ON/OFF switch Master switch to activate the system.

Removal and Installation of Front Wiper Arms, Adjustment of Wiper Arms Stop
Location
EKS00BE4
REMOVAL
1. Operate the wiper motor, and stop it at the auto stop position.
2. Remove the wiper arm mounting covers.
3. Remove the wiper arm mounting nuts, then remove the wiper arms.
INSTALLATION
1. Prior to wiper arm installation, turn on wiper switch to operate
wiper motor and then turn it "OFF" (Auto Stop).
2. Lift the blade up and then set it down onto glass surface to set
the blade center to clearance "L1" and "L2" immediately before
tightening nut.
3. Eject washer fluid. Turn on wiper switch to operate wiper motor
and then turn it "OFF".
4. Ensure that wiper blades stop within clearance "L1" and "L2".

Before reinstalling wiper arm, clean up the pivot area as illus-
trated. This will reduce possibility of wiper arm looseness.

Tighten wiper arm nuts to specified torque.
