• Bypass connection is never allowed at the repaired area.
NOTE:
Bypass connection may cause ITS communication error. The
spliced wire becomes separated and the characteristics of twisted
line are lost.

CAUTION:
• Never look straight into the laser beam discharger when adjusting laser beam aiming.
• Turn the MAIN switch OFF in conditions similar to driving, such as free rollers or a chassis dyna-
mometer.
• Never use the ICC sensor removed from vehicle. Never disassemble or remodel.
• Erase DTC when replacing parts of ICC system, then check the operation of ICC system after adjust-
ing laser beam aiming if necessary.

ADAS control unit
×
×
×
×
• ADAS control unit calculates a target distance between vehicles
and a target speed, based on signals received from each sensor
and switch to transmit an engine torque command value to ECM
and a brake fluid pressure control signal to ABS actuator and
electric unit (control unit) via CAN communication
• ADAS control unit transmits buzzer output signal to combination
meter via CAN communication
ICC sensor
×
×
×
×
• ICC sensor detects light reflected from a vehicle ahead by irra-
diating laser forward and calculates a distance from the vehicle
ahead and a relative speed, based on the detected signal
• ICC sensor transmits the presence/absence of vehicle ahead
and the distance from the vehicle to ADAS control unit via ITS
communication
ECM
×
×
×
×
• ECM transmits the accelerator pedal position signal, ICC brake
switch signal, stop lamp switch signal, ICC steering switch sig-
nal, etc. to ADAS control unit via CAN communication
• ECM controls the electric throttle control actuator based on the
engine torque demand received from the ADAS control unit via
CAN communication
ABS actuator and electric unit
(control unit)
×
×
×
×
• ABS actuator and electric unit (control unit) transmits the vehicle
speed signal (wheel speed), stop lamp signal and VDC/TCS/
ABS system operation condition to ADAS control unit via CAN
communication
• ABS actuator and electric unit (control unit) controls the brake,
based on a brake fluid pressure control signal received from the
ADAS control unit via CAN communication
BCM
×
BCM transmits the front wiper request signal to ADAS control unit
via CAN communication
TCM
×
×
TCM transmits the signal related to A/T control to ADAS control
unit via CAN communication
