same part number or with an equivalent part if 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.

Diagnosis
To ensure that the trouble diagnosis is done accurately and smoothly, observe “Precautions in Diagnosing Trou-
bles” and follow “ABS Diagnostic Flow Table”.
Precaution 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 Circuit 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 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 for the details of each step.
Step Action Yes No
1 Perform customer complaint analysis, problem symptom confir-
mation and diagnostic trouble code check record and clear-
ance.
Is there any trouble code?Go to Step 2. Go to Step 5.
2 Perform driving test.
Is trouble symptom identified?Go to Step 3. Go to Step 6.
3 Check diagnostic trouble code.
Is it malfunction code?Go to Step 4. Go to Step 5.
4 Inspect 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.
5 Inspect and repair referring to “Diagnosis Table” in Section 5.
Then perform final confirmation test after clearing diagnostic
trouble code.
Is trouble recur?Go to Step 7. End.
6 Check for intermittent problems referring to “Intermittent and
Poor Connection” in Section 0A and related circuit of trouble
code recorded in Step 3. Then perform final confirmation test
after clearing diagnostic trouble code.
Is trouble recur?Go to Step 7. End.
7 Perform diagnostic trouble code check record and clearance.
Is there any trouble code?Go to Step 4. Go to Step 5.

“ABS” Warning Lamp Check
Turn ignition switch ON and check that “ABS” warning lamp
comes ON for about 2 seconds and then goes OFF. If any faulty
condition is found, advance to Diagnostic Flow Table-A, B or C.
Diagnostic Trouble Code (DTC) Check
1) Test drive vehicle at 40 km/h for more than a minute.
2) Stop vehicle and while IG switch OFF, connect diagnosis
switch terminal (3) and ground terminal (2) of monitor con-
nector (1) with service wire (4).
3) Turn IG switch ON, read the flashing “ABS” warning lamp
which represents DTC as shown in example below and write
it down. When more than 2 DTC’s 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)
4) After completing the check, turn ignition switch off, discon-
nect service wire from monitor connector.
NOTE:
“ABS” warning lamp indicates only following DTCs, DTC
12 which means that no malfunction DTC is stored and
history DTC which indicates history trouble area. When
there is current trouble, “ABS” warning lamp remains ON
and therefore DTC is not indicated.

DTC Check (Using SUZUKI Scan Tool)
1) Connect SUZUKI scan tool to data link connector after set-
ting cartridge for ABS to it.
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 DTC’s by pre-
forming the following procedure.
1) Turn ignition switch OFF.
2) Using service wire (4), connect diag. switch terminal (3) of
monitor connector (1) to ground terminal (2).
3) With connection described in above step 2) maintained, turn
ignition switch ON.
4) Repeat ON/OFF operation of service wire (4) at ground ter-
minal (2) at least 5 times within 10 seconds.
5) Turn ignition switch OFF and disconnect service wire (4)
from monitor connector (1).
6) Perform “DRIVING TEST” (Step 2 of “ABS Diagnostic Flow
Table”) and “DTC CHECK” and confirm that normal DTC
(DTC 12) is displayed.
WARNING:
When preforming 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.
NOTE:
Service wire ON time must be for 0.1 second and more.
NOTE:
It is also possible to clear DTC by using SUZUKI scan
tool. Refer to Cartridge Manual for procedure to clear
DTC.

On-Vehicle Service
Precaution
When connectors are connected to ABS hydraulic unit / control
module assembly, do not disconnect connectors of sensors, fuse
etc. and turn ignition switch ON. Then DTC will be set in ABS con-
trol module.
ABS Hydraulic Unit Operation Check
1) Check that basic brake system other than ABS is in good
condition.
2) Check that battery voltage is 11 V or higher.
3) With ABS warning lamp, check that no abnormality is
detected in ABS. Refer to “Diagnostic Trouble Code (DTC)
Check” in this section.
4) Lift up vehicle.
5) Set transmission to neutral and release parking brake.
6) Turn each wheel gradually by hand to check if brake drag-
ging occurs. If it does, correct.
7) With diag. switch terminal (3) of monitor connector (1) con-
nected to ground terminal (2) by using service wire (4), turn
ignition switch ON and check if ABS warning lamp indicates
DTC 12.
When other DTC’s appear on display, refer to “ABS Diagnos-
tic Flow Table” in this section.
8) Turn ignition switch OFF.
9) Perform following checks with help of another person.
Brake pedal (1) should be depressed and then ignition
switch (2) turned ON by one person and wheel (3) should be
turned by another person’s hand. At this time, check that:
Operation sound of solenoid is heard and wheel turns only
about 0.5 sec (Brake force is depressurized).
Operation sound of pump motor is heard and pulsation is felt
at brake pedal.
10) If all 4-wheels cannot be checked during one ignition cycle
(OFF → ON), repeat Steps 8) and 9) till all 4 wheels are
checked.
If a faulty condition is found in Steps 9) and 10), replace
hydraulic unit.
11) Turn ignition switch OFF.
12) Remove service wire from monitor connector.

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:
Whether the following systems (parts) are used in the particular vehicle or not depends on vehicle
specifications. Be sure to bear this in mind when performing service work.
EGR valve
Heated oxygen sensor(s) or CO adjusting resistor
Three-way catalytic converter (TWC) and warm up three-way catalytic converter (WU-TWC)
