5E1-2 ANTILOCK BRAKE SYSTEM (ABS) (OPTIONAL)
GENERAL DESCRIPTION
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 is a 4-wheel type
which controls the fluid pressure applied to the wheel cylinder of each of the four brakes to prevent each wheel
from getting locked.
The component parts of this ABS includes 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.

In this ABS, ABS hydraulic unit (actuator assembly), ABS control module, pump motor relay and fail-safe relay
are combined as one component.

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 of 4 wheels.

Fail-safe (solenoid valve) relay which supplies power to solenoid valve in ABS hydraulic unit and pump motor
relay.

Pump motor relay which supplies power to pump motor in ABS hydraulic unit.

ªABSº warning lamp which lights to inform abnormality when system fails to operate properly.

G sensor which detects body deceleration speed. (For 4WD model only)
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 proportioning valve, by the signal from wheel sensor
independently of change of load due to load capacity and so on. And if the EBD system fails to operate properly,
the brake warning lamp lights to inform abnormality.
