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”.

Steering Column Removal and InstallationS7RS0B6206006
CAUTION!
Once the steering column is removed from
the vehicle, the column is extremely
susceptible to damage.
• Dropping the column assembly on its end could collapse the steering shaft or loosen
the plastic shear pins which maintain
column length.
• Leaning on the column assembly could cause it to bend or deform.
Any of the damage could impair the column’s
collapsible design.
Steering column mounting nuts should not
be loosened with steering shaft joint upper
side bolt tightened as this could cause
damage to shaft joint bearing.
NOTE
When servicing steering column or any
column-mounted component, remove
steering wheel. But when removing steering
column simply to gain access to instrument
panel components, leave steering wheel
installed on steering column.

Never rest a steering column assembly on
the steering wheel with the air bag (inflator)
module face down and column vertical.

CAUTION!
Never turn steering wheel while steering
lower shaft is removed.
Should it have been turned and contact coil
have got out of its centered position, it needs
to be centered again. Also, turning steering
wheel more than about two and a half turns
will break contact coil.

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”.

Step 1: Customer Complaint Analysis
Record details of the problem (failure, co mplaint) and how it occurred as described by the customer. For this purpose,
use of such an inspection form will fac ilitate collecting information to the point required for proper analysis and
diagnosis. Check if the problem described in “Customer ques tionnaire” occurs actually in the vehicle if necessary.
(This step should be performed with the customer if possible.) Customer problem inspection form (Example)
NOTE
This form is a standard sample. It should be modified according to conditions characteristic of each
market.

Hoist vehicle.
Inspect each boot for tear. A torn boot allows entry of
dust and water which can cause wear to steering rack
and pinion to produce noise as well as rust to result in
malfunction of steering system.
Even if boot tear is small, replace with new one.
Also, check each boot for dent. If there is a dent, keep
boot in most compressed st ate for some seconds to
correct dent.
Boots should be visually inspected for any damage, dent
and tear during every periodical inspection at specified
intervals and whenever vehicle is hoisted for any other
purpose.
Tie-Rod / Rack Boot Removal and InstallationS7RS0B6306008
Removal
1) Remove steering gear case assembly referring to
“Steering Gear Case Assembly Removal and
Installation”.
2) For ease of adjustment after installation, make marking (1) of tie-rod end lock nut position of tie-rod
thread.
3) Loosen tie-rod end lock nut and remove tie-rod end.
4) Remove boot band (2) and clip (1).
5) Remove boot from tie-rod.
