Switch OperationEKS00BLK
The system is operated by a master ON/OFF switch and four control switches, all mounted on the steering
wheel.
Component Vehicle-to-vehicle
distance control mode Conventional
(fixed speed)
cruise control mode Brake 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.

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.

FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationEKS00BDS
System DescriptionEKS00BDT
Both front wiper relays are located in the IPDM E/R (intelligent power distribution module engine room).
The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input ter-
minals. Terminal combination status is read by the BCM when the wiper switch is turned ON.
BCM controls front wiper LO, HI, and INT (intermittent) operation.
IPDM E/R (intelligent power distribution module engine room) operates the wiper motor according to CAN
communication signals from the BCM.
Power is supplied at all times
through 50A fusible link (letter f , located in the fuse and fusible link box)
to BCM terminal 70, and
through 30A fuse (No. 39, located in the IPDM E/R)
to front wiper relay (located in the IPDM E/R).
With the ignition switch in ON or START position, power is supplied
through 10A fuse (No. 9, located in the fuse block J/B)
to combination switch terminal 14, and
through 10A fuse (No. 59 located in the fuse and relay box)
to BCM terminal 38.
Ground is supplied
