REMOVAL
1) Raise, suitably support vehicle. Remove wheel if necessary.
2) Clean dirt and foreign material from both hose end or pipe end fittings. Remove brake hose and pipe.
INSTALLATION
1) Install brake hose and pipe by reversing removal procedure, noting the following points.
For installation, make sure that steering wheel is in straightforward position and hose has no twist or kink.
Check to make sure that hose doesn’t contact any part of suspension, both in extreme right and extreme left
turn conditions. If it does at any point, remove and correct. Fill and maintain brake fluid level in reservoir.
Bleed brake system.
2) Perform brake test and check installed part for fluid leakage.

General Description
The ABS (Antilock Brake System) is a system to prevent each wheel to lock during hard braking or braking on a
slippery road by controlling the fluid pressure from master cylinder to each brake (either brake caliper or wheel
cylinder).
The ABS of this vehicle monitors all four wheels (four sensors) and controls all four wheels when the system is
active.
The component parts of this ABS includes following parts in addition to those of the conventional brake system.
Wheel speed sensor senses revolution speed of each wheel and sends outputs to ABS control module.
In this ABS, ABS hydraulic unit (actuator assembly), ABS control module, pump motor transistor and fail-
safe transistor are combined as one component.
ABS control module 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 operates according to signal from ABS control module and controls fluid pressure applied
to wheel cylinder of each of 4 wheels.
Fail-safe transistor which supplies power to solenoid valve in ABS hydraulic unit.
Pump motor transistor supplies power to pump motor in ABS hydraulic unit.
“ABS” warning lamp lights to inform abnormality when system fails to operate properly.
G sensor which detects body deceleration speed.

FUEL TANK LEVEL (%)
This parameter indicates approximate fuel level in the fuel tank. As the detectable range of the fuel level sensor
is set as 0 to 100%, however, with some models whose fuel tank capacity is smaller, the indicated fuel level may
be only 70% even when the fuel tank is full.
PNP SIGNAL (PARK / NEUTRAL POSITION SIGNAL, P/N RANGE or D RANGE)
It is detected by signal from TCM.
D range : A/T is in “R”, “D”, “2” or “L” range.
P/N range : A/T is in “P” or “N” range or the above signal is not inputted from TCM.
EGR VALVE (%)
This parameter indicates opening rate of EGR valve which controls the amount of EGR flow.
PSP SW
The Power Steering Pressure switch parameter displays ON when steering wheel is turned all the way to the
right or left.
