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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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).
NOTE:
For the descriptions (items) not found in this section, refer to Section 5E1 of the Service Manual
mentioned in the FOREWORD of this manual.
All brake fasteners are important attaching parts in that they could affect the performance of vital
parts and systems, and/or could result in major repair expense. They must be replaced with one of
same part number or with an equivalent part if replacement becomes necessary. Do not use a
replacement part of lesser quality or substitute design. Torque values must be used as specified
during reassembly to assure proper retention of all parts. There is to be no welding as it may result
in extensive damage and weakening of the metal.

ANTILOCK BRAKE SYSTEM (ABS) 5E2-3
General Description
Components/Parts Location
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 sys-
tem.
Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.
ABS warning lamp which lights to inform abnormality when system fails to operate properly.
ABS hydraulic unit/control module assembly is incorporated ABS control module, ABS hydraulic unit (actua-
tor assembly), fail-safe relay and pump motor relay.
–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.
–Fail-safe relay (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.
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 sen-
sor independently of change of load due to load capacity and so on. And if the EBD system fails to operate prop-
erly, the brake warning lamp lights to inform abnormality.

4) Repeat disconnecting and reconnecting of service wire
between diagnosis and ground terminals 5 times or more at
about 1sec. interval within 10 seconds.
5) Turn ignition switch OFF and disconnect service wire from
monitor coupler.
6) Perform “DRIVING TEST” (Step 2 of “ABS DIAGNOSTIC
FLOW TABLE” in this section) and “DTC CHECK” and con-
firm that normal DTC (DTC 12) is displayed ; not malfunction
DTC.

DESCRIPTION
G sensor
While a vehicle is at stop or running, if the potential difference between the sensor signal terminal “E136-11” and
the sensor ground terminal “E136-13” is not within the specified voltage value, or if the signal voltage while at a
stop does not vary from that while running, this DTC is set.
Therefore, this DTC may be set when a vehicle is lifted up and its wheel(s) is turned. In such case, clear the
DTC and check again.
When G sensor is installed to 2WD vehicle, this DTC is set.
