5) Check relief pressure.
a) Increase engine speed to about 1500 r/min (rpm). Close
gauge valve gradually while watching pressure increase
indicated by gauge and take reading of relief pressure
(maximum hydraulic pressure).
When it is higher than specified values, possible cause is
malfunction of relief valve.
When it is lower than specified values, possible cause is
either failure of P/S pump or settling of relief valve spring.
Relief pressure (when gauge valve is closed) :
7650 – 8350 kPa (76.5 – 83.5 kg/cm
2, 1088 – 1187 psi)
b) Next, open gauge valve fully and increase engine speed to
about 1500 r/min (rpm). Then turn steering wheel to the left
or right fully and take reading of relief pressure.
When it is higher than specified values, possible cause is
malfunction of relief valve.
When it is lower than specified values, possible cause is
failure in steering gear box. Replace gear box.
Relief pressure (when gauge valve is opened) :
7650– 8350 kPa (76.5 – 83.5 kg/cm
2, 1088 – 1187 psi) CAUTION:
Be sure not to close gauge valve for longer than 10 sec-
onds.

CAUTION:
Be sure not to hold steering wheel at fully turned position
for longer than 10 seconds.

WARNING:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Please observe all WARNINGS and “Service Precautions” under “On-
Vehicle Service” in air bag system section before performing service on or around the air bag sys-
tem 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.
The procedures in this section must be followed in the order listed to disable the air bag system
temporarily and prevent false diagnostic trouble codes from setting. Failure to follow procedures
could result in possible activation of the air bag system, personal injury or otherwise unneeded air
bag system repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were
removed. If a fastener needs to be replaced, use the correct part number fastener for that application.
If the correct part number fastener is not available, a fastener of equal size and strength (or stronger)
may be used. Fasteners that are not reused, and those requiring thread-locking compound, will be
called out. The correct torque value must be used when installing fasteners that require it. If the above
procedures are not followed, parts or system damage could result.
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual
mentioned in the FOREWORD of this manual.

3C1-2 AIR BAG STEERING WHEEL AND COLUMN
General Description
This double tube type steering column has the following three important features in addition to the steering func-
tion:
The column is energy absorbing, designed 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 operations can be locked to inhibit theft of the vehi-
cle.
To insure the energy absorbing action, it is important that 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 other than the one recom-
mended in this manual or a sharp blow on the end of the steering shaft, leaning on the assembly, or dropping
the assembly 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 bags. The air bag (inflator) module
should be handled with care to prevent accidental deployment. When servicing, be sure to observe all WARN-
INGS in this section. Refer to “SERVICE PRECAUTIONS” in Section 10B.

repairs described under “CHECKING STEERING COLUMN FOR ACCIDENT DAMAGE” in this section as well
as “REPAIRS AND INSPECTIONS REQUIRED AFTER ACCIDENT” in Section 10B.
On-Vehicle Service

For service precautions, refer to “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in Section 10B.
Diagnosis and servicing
For diagnosis and servicing, refer to “DIAGNOSIS AND SERVICING” under “SERVICE PRECAUTIONS” in
Section 10B.
Disabling air bag system
For disabling air bag system, refer to “DISABLING AIR BAG SYSTEM” under “SERVICE PRECAUTIONS” in
Section 10B.
Enabling air bag system
For enabling air bag system, refer to “ENABLING AIR BAG SYSTEM” under “SERVICE PRECAUTIONS” in
Section 10B.

3C1-4 AIR BAG STEERING WHEEL AND COLUMN
Steering Column
REMOVAL
1) Disconnect negative (–) cable at battery.
2) Disable air bag system. Refer to “DISABLING AIR BAG SYSTEM” under “SERVICE PRECAUTIONS” in
Section 10B.
3) Remove steering wheel and contact coil and combination switch assembly, if necessary. Refer to “STEER-
ING WHEEL” and “CONTACT COIL AND COMBINATION SWITCH ASSEMBLY” in this section.
Perform the following procedure if not removing steering wheel and/or combination switch.
a) Turn steering wheel so that vehicle’s front tires are at straight-ahead position.
b) Turn ignition switch to “LOCK” position and remove key.
4) Remove steering column hole cover (1).
5) Disconnect all connectors for the following parts.
Contact coil and combination switch
Ignition switch CAUTION:
Once the steering column is removed from the vehicle, the column is extremely susceptible to dam-
age.
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 above damage could impair the column’s collapsible design.
When loosening steering column mounting bolts and nuts, make sure that steering column assembly
and steering upper shaft assembly have been separated. Loosening them with steering column
assembly and steering upper shaft assembly assembled could cause damage to upper joint and
mounting bracket in steering upper shaft assembly.
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 steer-
ing wheel installed on steering column.
WARNING:
Never rest a steering column assembly on the steering wheel with air bag (inflator) module face down
and column vertical. Otherwise personal injury may result.
CAUTION:
Never turn steering wheel while steering column with steering wheel is removed. Turning steering
wheel more than about two and a half turns will break contact coil.
