WARNING:
Wheel spin should be limited to 35 mph (55 km/h) as indicated on speedometer.
This limit is necessary because speedometer only indicates one-half of actual wheel speed when one
drive wheel is spinning and the other drive wheel is stopped.
Unless care is taken in limiting drive wheel spin, spinning wheel can reach excessive speeds. This
can result in possible tire disintegration or differential failure, which could cause serious personal
injury or extensive vehicle damage.
CAUTION:
For vehicle equipped with ABS, using on-vehicle balancing method with ignition switch ON may set
malfunction diagnostic trouble code (DTC) of ABS even when system is in good condition.
Never turn ignition switch ON while spinning wheel.

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:
When inspecting and servicing vehicle equipped with ABS, be sure to refer to section 5E first.
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 Control Module
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 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 in ABS control module.
4) When Diag. switch terminal of monitor connector is
grounded, the abnormal area is output as DTC.
For procedure to clear all DTC’s, refer to the item “Diagnostic
Trouble Code (DTC) Clearance” in this section.
Fail-safe function
When an abnormality occurs (an abnormal DTC is detected),
ABS control module turns OFF the fail-safe transistor which sup-
plies power to ABS hydraulic unit. Thus, with ABS not operating,
brakes function just like the brake system of the vehicle without

1) MALFUNCTION ANALYSIS
a) Customer Complaint Analysis
Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such a questionnaire form as shown below will facilitate collecting information to
the point required for proper analysis and diagnosis.
CUSTOMER QUESTIONNAIRE (EXAMPLE)
b) Problem Symptom Confirmation
Check if what the customer claimed in “Customer Questionnaire” is actually found in the vehicle and if the
symptom is found, determine whether it is identified as a failure. (This step should be shared with the cus-
tomer if possible.) When “ABS” warning lamp is not operating correctly, proceed to “Diagnostic Flow Table-
A, B or C” in this section.
c) Diagnostic Trouble Code (DTC) Check, Record and Clearance
Perform “Diagnostic Trouble Code Check” procedure in this section, record it and then clear it referring to
“Diagnostic Trouble Code Clearance” 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 mod-
ule 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 abnor-
mal lighting of “ABS” warning lamp) exists.
If the malfunction DTC is confirmed again at ignition switch ON, driving test as described in above is not nec-
essary. Proceed to Step 3.
3) DIAGNOSTIC TROUBLE CODE CHECK
Recheck diagnostic trouble code referring to “DTC Check” in this section.
4) DIAGNOSTIC TROUBLE CODE FLOW TABLE
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)“DIAGNOSIS TABLE” IN SECTION 5
Check the parts or system suspected as a possible cause referring to “Diagnosis Table” in Section 5 and
based on symptoms appearing on the vehicle (symptoms obtained through Step 1)-a, 1)-b 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
Intermittent Trouble in Section 0A and related circuit of trouble code recorded in Step 1)-c.
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 normal code is indicated.

“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.

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.
