Component Function
ABS actuator and electric unit (control unit) ABS operation signal is rece
ived from ABS actuator and el ectric unit (control unit)
via CAN communication.
ADAS control unit Intelligent brake assistance operation signal is received from ADAS control unit
via CAN communication.
Air bag diagnosis sensor unit Detects a collision and supplies power supply for deployment to air bag module
and pre-tensioner seat belt.
Performs the deploy judgement of passenger air bag based on the information from Occupant Detection System control unit
BCM Ignition ON signal, sleep/wake up signal, and door switch signal are received
from BCM via CAN communication.
Brake pedal stroke sensor It changes voltage according to brake pedal depressed amount and sends the
signal to pre-crash seat belt control unit.
There are 2 signals (brake pedal stroke sensor 1 and 2) sent from the brake
pedal stroke sensor. Pre-crash seat belt control unit judges the stroke amount
and the speed of the brake pedal according to the voltage of the signal sent by
each side.
Combination meter Transmits vehicle speed signal to pre-crash seat belt control unit (driver side).
Turns the seat belt warning lamp ON when the seat belt is unfastened.
Occupant detection system control unit Judges the passenger seat condition based on the information from occupant de-
tection unit.

nal.
Driver seat belt retractor integrates pre-crash seat belt control unit (driver side), driver seat belt motor, and tension reducer.
Seat belt motor operates each operation of pull, return, and hold.
Pre-crush seat belt control unit (passenger side) Control of passenger pre-crash seat belt is operated according to transmit sig-
nal.
Passenger seat belt retractor integrates pre-crash seat belt control unit (driver seat), driver seat belt motor, and tension reducer.
Seat belt motor operates each operation of pull, return, and hold.
Seat belt buckle switch (driver side) Fastening or not fastening of seat belt is judged. This judgment is used for con-
trol of driver pre-crash seat belt system.
Seat belt warning lamp on combination meter turns ON when seat belt is not fastened while ignition switch is ON.
The seat belt buckle switch is installed in the seat belt buckle.
Seat belt buckle switch (passenger side) Fastening or not fastening of seat belt is judged. This judgment is used to con-
trol passenger pre-crash seat belt system.
