5) Check relief pressure

Increase engine speed to about 1,500 r / min (rpm). Close
gauge valve gradually while watching pressure increase indi-
cated by gauge and take reading of relief pressure (maximum
hydraulic pressure).
Relief pressure:
6200 ± 7000 kPa
(62 ± 70 kg / cm
2, 882 ± 995 psi) G16 Type engine. . . . . . .
6700 ± 7500 kPa
(67 ± 75 kg / cm
2, 953 ± 1067 psi) J20 Type engine. . . . . . .
7050 ± 7850 kPa
(70.5 ± 78.5 kg / cm
2, 1003 ± 1116 psi) H25 Type engine. .

When it is higher than specified values, possible cause is mal-
function 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.
CAUTION:
Be sure not to close gauge valve for longer than 10 se-
conds.

Next, open gauge valve fully and increase engine speed to
about 1,500 r / min (rpm). Then turn steering wheel to the left
or right fully and take reading of relief pressure.
Relief pressure:
6200 ± 7000 kPa
(62 ± 70 kg / cm
2, 882 ± 995 psi) G16 Type engine. . . . . . .
6700 ± 7500 kPa
(67 ± 75 kg / cm
2, 953 ± 1067 psi) J20 Type engine. . . . . . .
7050 ± 7850 kPa
(70.5 ± 78.5 kg / cm
2, 1003 ± 1116 psi) H25 Type engine. .

When it is higher than specified values, possible cause is mal-
function of relief valve.

When it is lower than specified values, possible cause is failure
in steering gear box. Replace gear box.
CAUTION:
Be sure not to hold steering wheel at fully turned posi-
tion for longer than 10 seconds.
BOOT
STEERING RACK BOOT CHECK
Check boot for crack and damage which, if any, means possibility
of rusty gear, entry of dust or lack of grease. Also, check if any of
such faulty conditions exists.
Check steering rack boot for dent or breakage.
If there is a dent, keep boot in most compressed state for some se-
conds to correct dent.

SECTION 3C1
AIR BAG STEERING WHEEL AND COLUMN
WARNING:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Please observe all WARNINGS and ªService Precautionsº under ªOn-Vehicle
Serviceº in air bag system section before performing service on or around the air bag system compo-
nents 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 tem-
porarily 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 sys-
tem repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were re-
moved. 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 proce-
dures are not followed, parts or system damage could result.

CAUTION:
Removal of the steering wheel allows the contact coil to turn
freely but do not turn the contact coil (on the combination
switch) more than allowable number of turns (about two and
a half turns from the center position clockwise or counter-
clockwise respectively), or coil will break.
REMOVAL
1) Remove driver air bag (inflator) module from steering wheel re-
ferring to ªDRIVER AIR BAG (INFLATOR) MODULEº earlier in
this section.
2) Remove steering shaft nut.
3) Make alignment marks on steering wheel and shaft for a guide
during reinstallation.
4) Remove steering wheel with special tool.
Special Tool
(A): 09944-36011
CAUTION:
Do not hammer the end of the shaft. Hammering it will
loosen the plastic shear pins which maintain the column
length and impair the collapsible design of the column.
CENTERING CONTACT COIL
1) Check that vehicle's wheels (front tires) are set at straight-ahead
position.
2) Check that ignition switch is at ªLOCKº position.
3) Turn contact coil counterclockwise slowly with a light force till
contact coil will not turn any further.
NOTE:
Contact coil can turn about 5 turns at maximum, that is, if
it is at the center position, can turn about two and a half
turns both clockwise and counterclockwise.
4) From the position where contact coil became unable to turn any
further (it stopped), turn it back clockwise about two and a half
rotations and align center mark with alignment mark.

INSPECTION
Check contact coil and combination switch wire harness for any
signs of scorching, melting or other damage. If it is damaged, re-
place.
INSTALLATION
1) Check to make sure that vehicle's front tires are set at straight-
ahead position and then ignition switch is at ªLOCKº position.
2) Install contact coil and combination switch assembly to steering
column.
NOTE:
New contact coil and combination switch assembly is sup-
plied with contact coil set and held at its center position
with a lock pin and seal. Remove this lock pin after installing
contact coil and combination switch assembly to steering
column.

FRONT SUSPENSION
CAUTION:

All front suspension fasteners are an important attaching part in that it 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 this part.

Never attempt to heat, quench or straighten any front suspension part. Replace it with a new part or
damage to the part may result.

STABILIZER BAR AND BUSHING CHECK
BAR
Inspect for damage or deformation. If defective, replace.
BUSHING
Inspect for damage, wear or deterioration. If defective, replace.
STRUT DAMPER AND / OR COIL SPRING
CHECK
1) Inspect strut for oil leakage. If strut is found faulty, replace it as
an assembly unit, because it can not be disassembled.
2) Strut function check
Check and adjust tire pressures as specified.
Bounce body three or four times continuously by pushing front
end on the side with strut to be checked. Apply the same amount
of force at each push and note strut resistance both when
pushed and rebounding.
Also, note how many times vehicle body rebounds before com-
ing to stop after hands are off. Do the same for strut on the other
side.
Compare strut resistance and number of rebound on the right
with those on the left.
And they must be equal in both. With proper strut, body should
come to stop the moment hands are off or after only one or two
small rebounds. If struts are suspected, compare them with
known good vehicle or strut.
3) Inspect for damage or deformation.
4) Inspect strut boot for damage or crack.
5) Inspect for cracks or deformation in spring seat.
6) Inspect for deterioration of bump stopper.
7) Inspect strut mount for wear, cracks or deformation.
Replace any parts found defective in steps 2) ± 7).
SUSPENSION ARM / KNUCKLE CHECK
Inspect for cracks, deformation or damage.
