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.

GENERAL DESCRIPTION
Seat belt with ELR
The seat belt with Emergency Locking Retractor (ELR) is designed so that it locks immediately (to prevent the web-
bing from being pulled out of the retractor any further) when any of the following items is detected as exceeding
each set value; speed at which the webbing is pulled out of the retractor, acceleration or deceleration of the vehicle
speed, and inclination.
Seat belt with A-ELR
The automatic and emergency locking retractor (A-ELR) works as an Emergency Locking Retractor (ELR) till its
webbing is pulled all the way out and then on as an Automatic Locking Retractor (ALR) till it is retracted fully.
ALR: Automatically locks when the webbing is pulled out from the retractor and allowed to retract even a little.
Then the webbing can not be pulled out any further, unless it is wound all the way back into the retractor, which
releases the lock and allows the webbing to be pulled out.
Driver and front passenger side air bags
The driver and front passenger side air bags are components of the air bag system. In occurrence of a front collision
with an impact larger than a certain set value, they are activated by the ignition signal from SDM to supplement
protection offered by the driver and front passenger seat belts.

the driver air bag (inflator) module is deployed from the center of the steering column

the passenger air bag (inflator) module from the top of the instrument panel in front of the front passenger seat

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were re-
moved. If a fastener needs to be replaced, use the correct part number fastener for that application. If
the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may
be used. Fasteners that are not reused, and those requiring thread-locking compound, will be called
out. The correct torque value must be used when installing fasteners that require it. If the above proce-
dures are not followed, parts or system damage could result.

ON-VEHICLE SERVICE
SERVICE PRECAUTIONS
WARNING:
If replacing seat belt is necessary, replace buckle and ELR (or webbing) together as a set. This is for
the reason of ensuring locking of tongue plate with buckle. If these parts are replaced individually, such
a locking condition may become unreliable. For this reason, SUZUKI will supply only the spare buckle
and ELR (or webbing) in a set part.
Before servicing or replacing seat belts, refer to following precautionary items.

Seat belts should be normal relative to strap retractor and buckle portions.

Keep sharp edges and damaging objects away from belts. Avoid bending or damaging any portion of belt buckle,
latch plate and ELR.

Do not bleach or dye belt webbing. (Use only mild soap and lukewarm water to clean it.)

When installing a seat belt anchor bolt, start bolt by hand to prevent cross-threading.

Use only the correct seat belt anchor bolts and screws and tighten to the correct torque value.

Do not attempt any repairs on retractor mechanisms or retractor covers. Replace defective assemblies with new
replacement parts.

Keep belts dry and clean at all times.

If there exist any parts in question, replace such parts.

Replace belts whose webbing is cut or otherwise damaged.

Do not put anything into trim panel opening which seat belt webbing passes through.
