11) Disconnect horn connector (1) from instrument panel har-
ness.
12) If equipped with power steering (P/S) system, disconnect
connector (2) from P/S control module (1).
13) Remove steering joint cover.
14) Make alignment marks (1) on joint (2) of steering column and
steering lower shaft (3) for a guide during reinstallation.
15) Remove joint bolt (steering column side) (4).
16) Remove steering column mounting nuts (“A”, “B”).
17) Remove steering column assembly from vehicle.
18) If it is necessary to remove steering lock assembly (ignition
switch), remove it, referring to “STEERING LOCK ASSEM-
BLY (IGNITION SWITCH)” in this section.
CAUTION:
Don’t separate steering column assembly into steering
column and shaft. If column or shaft is defective, replace
as an assembly.

3F-4 WHEELS AND TIRES
Dynamic balance, as shown in left figure, is the equal distribution
of weight on each side of the wheel centerline so that when the
tire spins there is no tendency for the assembly to move from side
to side. Wheels that are dynamically unbalanced may cause
shimmy.
GENERAL BALANCE PROCEDURES
Deposits of mud, etc. must be cleaned from inside of rim.
Each tire should be inspected for any damage, then balanced according to equipment manufacturer’s recom-
mendation.
OFF-VEHICLE BALANCING
Most electronic off-vehicle balancers are more accurate than the on-vehicle spin balancers. They are easy to
use and give a dynamic (two plane) balance. Although they do not correct for drum or disc unbalance as does
on-vehicle spin balancing, this is overcome by their accuracy, usually to within 1/8 ounce.
ON-VEHICLE BALANCING
On-vehicle balancing methods vary with equipment and tool manufacturers. Be sure to follow each manufac-
turer’s instructions during balancing operation.
1. Heavy spot wheel shimmy [C] : Before correction
2. Balance weights addition point [D] : Corrective weights
3. C/L of spindle
WARNING:
Stones should be removed from the tread in order to avoid operator injury during spin balancing and
to obtain good balance.
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.

SPECIFICATIONS DIFFERENT FROM ABS
CONTROL MODULE SPECIFICATIONS .. 5E-22 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
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:
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 replace-
ment part of lesser quality or substitute design. Torque values must be used as specified during reas-
sembly 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 as well as
ABS 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 function just like the brake system of the vehicle without
ABS.

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 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 abnor-
mal lighting of ABS warning light) 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” as shown in the following page.
4) DIAGNOSTIC TROUBLE CODE FLOW TABLE
According to Diagnostic flow table for the diagnostic trouble code confirmation in Step 3), locate the cause of
the trouble, namely in a sensor, switch, wire harness, connector, actuator assembly or other part and repair
or replace faulty parts.
5)“DIAGNOSIS” IN “BRAKES” SECTION
Check the parts or system suspected as a possible cause referring to “DIAGNOSIS” in “BRAKES” section
and based on symptoms appearing on the vehicle (symptom obtained through Steps 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 “GENERAL INFORMATION” section 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 no DTC is indicated.
