cylinder. Place a cloth (1) to prevent piston
from damage. It should be taken out
gradually with moderately compressed air.
Do not place your fingers in front of piston
when using compressed air.
2) Remove cylinder boot.

General Description
ABS DescriptionS7RS0B4501001
The ABS (Antilock Brake System) controls the fluid
pressure applied to the wheel cylinder of each brake
from the master cylinder so that each wheel is not locked
even when hard braking is applied.
This ABS has also the following function.
While braking is applied, but before ABS control
becomes effective, braking force is distributed between
the front and rear so as to prevent the rear wheels from
being locked too early for better stability of the vehicle.
The main component parts of this ABS include the
following parts in addition to those of the conventional
brake system.
• Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.
• ABS warning light which light s to inform abnormality
when system fails to operate properly.
• ABS hydraulic unit / cont rol module assembly is
incorporated ABS co ntrol module, ABS hydraulic unit
(actuator assembly), solenoid valve power supply
driver (transistor), solenoid valve driver (transistor),
pump motor driver (transistor).
– ABS control module which sends operation signal to ABS hydraulic unit to control fluid pressure
applied to each wheel cylinder based on signal
from each wheel speed sensor so as to prevent
wheel from locking.
– ABS hydraulic unit which operates according to signal from ABS control module to control fluid
pressure applied to wheel cylinder of each 4
wheels.
– Solenoid valve power supp ly driver (transistor)
which supplies power to solenoid valve in ABS
hydraulic unit.
– Solenoid valve driver (transistor) which controls each solenoid valves in ABS hydraulic unit.
– Pump motor driver (transistor) which supplies power to pump motor in ABS hydraulic unit.
This ABS is equipped with Electronic Brake force
Distribution (EBD) system that controls a fluid pressure
of rear wheels to best condition, which is the same
function as that of proportion ing valve, by the signal from
wheel sensor independently of change of load due to
load capacity and so on. An d if the EBD system fails to
operate properly, the brake warning light lights to inform
abnormality.
ABS Hydraulic Unit / Control Module Assembly
Description
S7RS0B4501002
ABS control module is a component of ABS hydraulic
unit / control module asse mbly and has the following
functions.
Self-Diagnosis Function
ABS control module diagnose s conditions of the system
component parts (whether or not there is any
abnormality) all the time and indicates the results
(warning of abnormality occurrence and DTC) through
the ABS warning light as described.
• When ignition switch is turned ON, ABS warning light lights for 2 seconds to check its circuit.
• When no abnormality has been detected (the system is in good condition), ABS warning light turns OFF
after 2 seconds.
• When an abnormality in th e system is detected, ABS
warning light lights and the area where that
abnormality lies is stored in the memory of EEPROM
in ABS control module.
