3A-2 FRONT END ALIGNMENT
GENERAL DESCRIPTION
Front alignment refers to the angular relationship between the
front wheels, the front suspension attaching parts and the ground.
Generally, the only adjustment required for front alignment is toe
setting.
Camber and caster can’t be adjusted. Therefore, should camber
or caster be out of specification due to the damage caused by
hazardous road conditions or collision, whether the damage is in
body or in suspension should be determined. If the body is dam-
aged, it should be repaired and if suspension is damaged, it
should be replaced.
TOE SETTING
Toe is the turning in or out of the front wheels. The purpose of a
toe specification is to ensure parallel rolling of the front wheels
(Excessive toe-in or toe-out may increase tire wear).
Toe-in
“B”-“A” : 0 ± 1 mm (0 ± 0.039 in.)
For adjusting toe setting, refer to “TOE ADJUSTMENT” in this
section.
CAMBER
Camber is the tilting of the front wheels from the vertical, as
viewed from the front of the vehicle. When the wheels tilt outward
at the top, the camber is positive. When the wheels tilt inward at
the top, the camber is negative. The amount of tilt is measured in
degrees.

WARNING:
For vehicles equipped with a Air Bag System
Service on or around air bag system components or wiring must be performed only by an autho-
rized suzuki dealer. Please observe all WARNINGS and CAUTIONS in SECTION 10B and Precau-
tions, Air Bag System Components and Wiring Location view in Section 10B before performing
service on or around air bag system components or wiring. Failure to follow WARNINGS could
result in unintended 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 deployed by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
All steering gear 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 the 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 dur-
ing reassembly to assure proper retention of these parts.

GENERAL DESCRIPTION
SYSTEM COMPONENTS
This power steering (P/S) system consists of a P/S control module, a torque sensor, a motor and clutch installed
to the steering column.
In this system, the P/S control module determines the level and direction of the assist force for the steering
wheel according to the signals from the torque sensor and the vehicle speed, runs the motor so as to assist
operation of the steering wheel.
P/S control module diagnoses troubles which may occur in the area including the following components when
the ignition switch is ON and the engine is running. When P/S control module detects malfunction, it stops the
motor and clutch control.
Torque sensor
Vehicle speed sensor (VSS) circuit
Engine speed signal circuit

Clutch

NOTE:
The location of steering wheel/column and ECM to RH steering vehicle are opposite to those location
to LH steering vehicle.

3B1-4 ELECTRICAL POWER STEERING (P/S) SYSTEM
DIAGNOSIS
The P/S system in this vehicle is controlled by P/S control module. P/S control module has an on-board diagnos-
tic system which detects a malfunction in this system.
When diagnosing troubles, be sure to have full understanding of the outline of “ON-BOARD DIAGNOSTIC SYS-
TEM” and each item in “PRECAUTION IN DIAGNOSING TROUBLE” and execute diagnosis according to “SYS-
TEM CHECK FLOW TABLE”.
ON-BOARD DIAGNOSTIC SYSTEM
P/S control module performs on-board diagnosis (self-diagnosis)
on the system and operates “EPS” warning lamp (1) (malfunction
indicator lamp) as follows.
Malfunction indicator lamp (“EPS” warning lamp) lights when
the ignition switch is turned to ON position (but the engine at
stop) regardless of the condition of P/S control system. This
is only to check the malfunction indicator lamp (“EPS” warn-
ing lamp) bulb and its circuit.
If the areas monitored by P/S control module is free from any
trouble after the engine start (while engine is running), mal-
function indicator lamp (“EPS” warning lamp) turns OFF.
When P/S control module detects a trouble which has
occurred in the areas it monitors, malfunction indicator lamp
(“EPS” warning lamp) turns ON while the engine is running
to warn the driver of such occurrence of trouble and at the
same time it stores the exact trouble area in memory inside
of P/S control module.
PRECAUTIONS IN DIAGNOSING TROUBLES
Take a note of DTC indicated first.
Be sure to read “PRECAUTIONS FOR ELECTRONIC CIRCUIT SERVICE” in Section 0A before inspection
and observe what is written there.
When two or more troubles have occurred, their DTCs are indicated 3 times each starting with the smallest
code number and up.
DTC C1122 (DTC No.22) (engine speed signal failure) is indicated when ignition switch is ON position and
engine is not running but if indication changes to a normal one when engine is started, it means nothing
abnormal.
As DTC is stored in memory of P/S control module, be sure to clear memory after repair by performing the
procedure described in “DTC CLEARANCE”.
