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.

ABS Hydraulic Unit/control Module Assembly
ABS control module is a component of ABS hydraulic unit/control
module assembly and has the following functions.
Self-diagnosis function
ABS control module diagnoses conditions of the system compo-
nent 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 lamp as described below.
1) When ignition switch is turned ON, ABS warning lamp lights
for 2 seconds to check its bulb and circuit.
2) When no abnormality has been detected (the system is in
good condition), ABS warning lamp turns OFF after 2 sec-
onds.
3) When an abnormality in the system is detected, ABS warn-
ing lamp lights and the area where that abnormality lies is
stored in the memory of EEPROM in ABS control module.
4) When Diag. switch terminal (2) of diagnosis connector (1)
(monitor connector) is grounded, the abnormal area is output
as DTC. It is indicated by flashing of ABS warning lamp.
(Refer to the table below.)
5) For procedure to clear all DTC’s, refer to “DIAGNOSTIC
TROUBLE CODE CLEARANCE” in this section.
Also ABS control module turns ON EBD warning lamp (brake
warning lamp) depending on the trouble that detected by the
module and EBD warning lamp does not indicate DTC.
Fail-safe function
When an abnormality occurs (an abnormal DTC is detected),
ABS control module turns OFF the fail-safe relay which supplies
power to ABS hydraulic unit. Thus, with ABS not operating,
brakes function just like the brake system of the vehicle without
ABS.

Diagnosis
To ensure that the trouble diagnosis is done accurately and
smoothly, observe “PRECAUTIONS IN DIAGNOSING TROU-
BLES” and follow “ABS DIAGNOSTIC FLOW TABLE”.
Precautions in Diagnosing Troubles
If the vehicles was operated in any of the following ways,
ABS warning lamp may light momentarily but this does not
indicate anything abnormal in ABS.
–The vehicle was driven with parking brake pulled.
–The vehicle was driven with brake dragging.
–The vehicle was stuck in mud, sand, etc.
–Wheel spin occurred while driving.
–Wheel(s) was rotated while the vehicle was jacked up.
Be sure to read “PRECAUTIONS FOR ELECTRONIC CIR-
CUIT SERVICE” in Section 0A before inspection and
observe what is written there.
Be sure to use the trouble diagnosis procedure as described
in the flow table. Failure to follow the flow table may result in
incorrect diagnosis. (Some other diagnosis trouble code may
be stored by mistake in the memory of ABS control module
during inspection.)
When disconnecting ABS hydraulic unit/control module con-
nector (1), pull up lock (2) of connector.
When connecting, set the connector on ABS hydraulic unit/
control module assembly and push the lock (2) down.

Diagnostic Trouble Code (DTC) Check (Using
ABS Warning Lamp)
1) Perform ABS WARNING LAMP CHECK described above.
2) Using service wire (4), connect diagnosis switch terminal (2)
of monitor coupler (1) to ground (3).
3) Turn ignition switch ON.
4) Read flashing of ABS warning lamp which represents DTC
as shown in example below and write it down. When more
than 2 DTCs are stored in memory, flashing for each DTC is
repeated three times starting with the smallest DTC number
in increasing order.
For details of DTC, refer to “DTC TABLE”.
Example : When right-front wheel speed sensor circuit opens (DTC 21)
5) After completing the check, turn ignition switch off, discon-
nect service wire from monitor coupler.

ANTILOCK BRAKE SYSTEM (ABS) 5E2-11
Diagnostic Trouble Code (DTC) Check (Using
SUZUKI Scan Tool)
1) After setting cartridge for ABS to SUZUKI scan tool, connect
SUZUKI scan tool to data link connector.
Special tool
(A) : SUZUKI scan tool
2) Turn ignition switch ON.
3) Read DTC according to instructions displayed on SUZUKI
scan tool and print it or write it down. Refer to SUZUKI scan
tool operator’s manual for further details.
4) After completing the check, turn ignition switch off and dis-
connect SUZUKI scan tool from DLC.
Diagnostic Trouble Code (DTC) Clearance
After repair or replace malfunction part(s), clear all DTCs by per-
forming the following procedure.
1) Turn ignition switch OFF.
2) Using service wire (4), connect diagnosis switch terminal (2)
of diagnosis monitor coupler (1) to ground terminal (3).
3) With connection described in above Step 2) maintained, turn
ignition switch ON.
WARNING:
When performing a driving test, select a safe place where
there is neither any traffic nor any traffic accident possi-
bility and be very careful during testing to avoid occur-
rence of an accident.
