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).
NOTE:
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 hydrauli 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 ªABSº warning lamp as described below.
1) When ignition switch is turned ON, ªABSº 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), ªABSº warning lamp turns OFF after 2 seconds.
3) When the vehicle starts to move after the ignition switch is turned
ON (more than one wheel speed sensor signals are inputted),
solenoid valves and motor of ABS hydraulic unit operate once
one after another for electrical check.
During this check, motor operation sound may be heard but that
means nothing abnormal.
4) When an abnormality in the system is detected, ªABSº warning
lamp lights and the area where that abnormality lies is stored in
the memory of EEPROM in ABS control module.
5) When Diag. switch terminal of diagnosis connector (monitor
connector) is grounded, the abnormal area is output as DTC. It
is indicated by flashing of ªABSº warning lamp. (Refer to the
table below. )

For procedure to clear all DTC's, refer to the item ªDiagnostic
Trouble Code Clearanceº in this section.
Also ABS control module turns ON EBD warning lamp (brake warn-
ing lamp) depending on the trouble that detected by the module and
EBD warning lamp does not indicate DTC as well as ªABSº warning
lamp.
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 func-
tion just like the brake system of the vehicle not equipped with ABS.

DIAGNOSIS
To ensure that the trouble diagnosis is done accurately and smooth-
ly, observe ªPrecautions in Diagnosing Troublesº and follow ªABS
Diagnostic Flow Tableº.
PRECAUTION IN DIAGNOSING TROUBLES

If the vehicle was operated in any of the following ways, ªABSº
warning light may light momentarily but this does not indicate any-
thing 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 ªPrecautions for Electronic Circuit Serviceº in
ªGENERAL INFORMATIONº section before inspection and ob-
serve 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 incor-
rect diagnosis. (Some other diag. trouble code may be stored by
mistake in the memory of ABS control module during inspection.)

ABS DIAGNOSTIC FLOW TABLE
Refer to the following pages for the details of each step.
STEP
ACTIONYESNO
1Perform customer complaint analysis, problem
symptom confirmation and diagnostic trouble code
check record and clearance. Is there any trouble code?Go to step 2.Go to step 5.
2Perform driving test. Is trouble symptom identified?Go to step 3.Go to step 6.
3Check diagnostic trouble code. Is it malfunction
code?Go to step 4.Go to step 5.
4Inspect and repair referring to applicable diagnostic trouble
code table in this section. Then perform final confirmation
test after clearing diagnostic trouble code. Is trouble recur?Go to step 7.END.
5Inspect and repair referring to DIAGNOSIS in
ªBRAKESº section. Then perform final confirmation test
after clearing diagnostic trouble code. Is trouble recur?Go to step 7.END.
6Check for intermittent problems referring to
INTERMITTENT AND POOR CONNECTION in
ªGENERAL INFORMATIONº section and related circuit
of trouble code recorded in step 1. Then perform final
confirmation test after clearing diagnostic trouble code.
Is trouble recur?Go to step 7.END.
7Perform diagnostic trouble code check record

1-2. PROBLEM SYMPTOM CONFIRMATION
Check if what the customer claimed in CUSTOMER QUESTIONNAIRE is actually found in the vehicle and
if that symptom is found, whether it is identified as a failure. (This step should be shared with the customer
if possible.) When ªABSº warning lamp is not operated correctly, proceed to ªDiagnostic Flow Table-A, B or
Cº.
1-3. DIAGNOSTIC TROUBLE CODE (DTC) CHECK, RECORD AND CLEARANCE
Perform ªDiagnostic Trouble Code Checkº as shown below, record it and then clear it referring to ªDiagnostic
Trouble Code Clearanceº in this section.
If the malfunction DTC which was once displayed and then cleared cannot be detected (indicated) again when
the ignition switch is turned ON, attempt to diagnose the trouble based on the DTC recorded in this step may
mislead the diagnosis or make diagnosing difficult. Proceed to Step 2 to check ABS control module for proper
self-diagnosis function.
If the malfunction DTC which was once displayed and then cleared can be detected (indicated) again when
ignition switch is turned ON, proceed to Step 3.
2. DRIVING TEST
Test drive the vehicle at 40 km / h for more than a minute and check if any trouble symptom (such as abnormal
lighting of ªABSº warning lamp) exists.
If the malfunction DTC is confirmed again at ignition switch ON, driving test as described in above is not neces-
sary. Proceed to Step 3.
3. DIAGNOSTIC TROUBLE CODE CHECK
Recheck diagnostic trouble code referring to item ªDTC CHECKº as shown below.
4. DIAGNOSTIC TROUBLE CODE FLOW CHART
According to Diagnostic flow table for the diagnostic trouble code confirmed in Step 3, locate the cause of the
trouble, namely in a sensor, switch, wire harness, connector, actuator, ABS control module or other part and
repair or replace faulty parts.
5. ªDIAGNOSISº IN ªBRAKEº SECTION
Check the parts or system suspected as a possible cause referring to ªDiagnosisº in ªBRAKESº section and
based on symptoms appearing on the vehicle (symptoms obtained through Steps 1-1, 1-2 and 2 and repair or
replace faulty parts, if any.
6. CHECK FOR INTERMITTENT PROBLEM
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to IN-
TERMITTENT TROUBLE in ªGENERAL INFORMATIONº section and related circuit of trouble code recorded
in Step 1-3.
7. FINAL CONFIRMATION TEST
Confirm that the problem symptom has gone and the ABS is free from any abnormal conditions. If what has been
repaired is related to the malfunction DTC, clear the DTC once and perform test driving and confirm that a nor-
mal code is indicated.
