General Description
Steering Wheel and Column ConstructionS7RS0B6201001
This double tube type steering column has the following three important features in addition to the steering function:
• The column is energy absorbing, desig ned to compress in a front-end collision.
• The ignition switch and lock are mounted conveniently on this column.
• With the column mounted lock, the ignition and steering op erations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important th at only the specified screws, bolts and nuts be used as
designated, and that they are tightened to the specified torque. When the column assembly is removed from the
vehicle, special care must be taken in handling it. Use of a steering wheel puller or a sharp blow on the end of the
steering shaft, leaning on the assembly, or dropping the a ssembly could shear the plastic shear pins which maintain
column length and position.
The driver air bag (inflator) module is one of the supplemental restraint (air bag) system components and is mounted
to the center of the steering wheel. During certain frontal crashes, the air bag system supplements the restraint of the
driver’s and passenger’s seat belts by deploying the air b ags. The air bag (inflator) module should be handled with
care to prevent accidental deployment. When servicing, be sure to observe “Precautions on Service and Diagnosis of
Air Bag System in Section 8B”.

Precautions
Steering System NoteS7RS0B6300001
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
during reassembly to assure proper retention of these parts.
Precautions in Diagnosing TroublesS7RS0B6300002
• Take a note of DTC indicated on the SUZUKI scan tool.
• Before inspection, be sure to read “Pre cautions for Electrical Circuit Service in Section 00” and understand what is
written there.
• DTC C1122 (engine speed signal failure) is indicated when ignition switch is at ON position and engine is not
running, but it means there is nothing abnormal if indica tion changes to a normal one when engine is started.
• As DTC is stored in memory of the P/S control module, be sure to clear memory after repair by performing the
procedure described in “DTC Clearance”.

General Description
P/S System DescriptionS7RS0B6301001
This power steering (P/S) system consists of a P/S control module (3), a torque sensor (4), a motor (5). In this system,
the P/S control module determines the level and direction of the assist force for the steering wheel (1) according to the
signals from the torque sensor and vehicle speed signal from ECM. The P/S control module runs the motor so as to
assist the operation of the steering wheel.
The 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 the P/S control module detects any malfunction, it stops the
motor operation.
• Torque sensor
• Vehicle speed signal
• Engine speed signal
• P/S motor
• P/S control module.

EPS Diagnosis General DescriptionS7RS0B6301002
The P/S system in this vehicle is controlled by the P/S control module. T he P/S control module has an on-board
diagnostic system which detects a malfunction in this system. When diagnosing troubles, be sure to have full
understanding of the outline of “On-Board Diagnostic Sy stem Description” and each item in “Precautions in
Diagnosing Troubles”, and then execute diagnosis according to “EPS System Check”.
On-Board Diagnostic System DescriptionS7RS0B6301003
The P/S control module performs the on -board diagnosis (self-diagnosis) on the system and operates the “EPS”
warning light (1) as follows.
• The “EPS” warning light lights when the ignition switch is turned to ON position (but the engine at stop) regardless
of the condition of the P/S co ntrol system. This is only to check if the “EPS” warning light is operated properly.
• If the areas monitored by the P/S control module is free from any trouble after the engine start (while engine is
running), the “EPS” warning light turns OFF.
• When the P/S control module detects a trouble which has occurred in th e monitored areas the “EPS” warning light
comes ON while the engine is running to warn the driver of such occurrence of the trouble and at the same time it
stores the exact trouble area in memory inside of the P/S control module.
Driving Cycle
A “Driving Cycle” consists of en gine startup and engine shutoff.
3 Driving Cycles Detection Logic
The malfunction detected in the first and second driving cycl e is stored in P/S control module memory (in the form of
pending DTC) but the “EPS” wa rning light does not light at these time. It lights up at t he third detection of same
malfunction also in the next driving cycle.
