STEERING, SUSPENSION, WHEELS AND TIRES 3-7
RADIAL TIRE LEAD
“Lead” is the deviation of the vehicle from a straight path on a level rod even with no pressure on the steering
wheel.
Lead is usually caused by:
Incorrect alignment.
Uneven brake adjustment.
Tire construction.
The way in which a tire is built can produce lead in a vehicle. An example of this is placement of the belt. Off
center belts on radial tires can cause the tire to develop a side force while rolling straight down the road. If one
side of the tire has a little larger diameter than the other, the tire will tend to roll to one side. This will develop a
side force which can produce vehicle lead.
The procedure in above figure (Lead Diagnosis) should be used to make sure that front alignment is not mis-
taken for tire lead.
Part of the lead diagnosis procedure is different from the proper tire rotation pattern currently in the owner
and service manuals. If a medium to high mileage tire is moved to the other side of the vehicle, be sure to
check that ride roughness has not developed
Rear tires will not cause lead.
VIBRATION DIAGNOSIS
Wheel unbalance causes most of the highway speed vibration problems. If a vibration remains after dynamic
balancing, its possible causes are as follows.
Tire runout.
Wheel runout.
Tire stiffness variation.
Measuring tire and/or wheel free runout will uncover only part of the problem. All three causes, known as loaded
radial runout, must be checked by using a Tire Problem Detector (TPD). If TPD is not available, alternative
method of substituting known-good tire and wheel assemblies on the problem vehicle can be used, although it
takes a longer time.
[A] : Tire out of round 1. Smooth road
[B] : Tire stiffness variation 2. Suspension movement (loaded runout)
[C] : Rim bent or out of round

MANUAL RACK AND PINION 3B-9
INSTALLATION
1) Mount steering gear case (2) to body and tighten gear case
mount bolts (1) to specified torque.
Tightening torque
Gear case mount bolt (a) : 25 N·m (2.5 kg-m, 18.0 lb-ft)
2) Install exhaust No.1 pipe (3).
3) Install both tie rod ends (1) to knuckles (2). Tighten each
castle nut (3) until holes for split pin (4) align but within spec-
ified torque and then bend new split pin as shown.
Tightening torque
Castle nut (b) : 43 N·m (4.3 kg-m, 31.5 lb-ft)
4) Be sure that steering wheel and both brake discs are all
straight ahead driving state and then insert steering lower
joint into steering pinion shaft.
5) Tighten steering shaft joint bolts to specified torque (Lower
side (2) first and then upper side (1)).

DTC CHECK
USING SUZUKI SCAN TOOL
1) Turn ignition switch to OFF position.
2) After setting cartridge connect SUZUKI scan tool to data link
connector (DLC) (1) located on underside of instrument
panel at driver’s seat side.
Special tool
(A) : 09931-76011
(B) : Master storage cartridge
(C) : 09931-76030
3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on SUZUKI
scan tool and print it or write it down referring to SUZUKI
SCAN TOOL OPERATOR’S MANUAL for further details.
5) After completing the check, turn ignition switch to OFF posi-
tion and disconnect SUZUKI scan tool from DLC.
NOT USING SUZUKI SCAN TOOL
1) Remove glove box.
2) Apply chocks to wheels, set shift lever to neutral position and
pull parking brake fully.
3) Start engine.
4) Using jumper wire (4), short diagnosis switch terminal (1) to
ground terminal (2) of monitor coupler (3).
5) Read flashing of “EPS” warning lamp which represents DTC
and write it down. When more than 2 DTCs are stored in
memory, each DTC is repeated 3 times starting with the
smallest DTC number in increasing order.
For details and example of DTC, refer to “DTC TABLE”.
6) After completing the check, turn ignition switch to OFF posi-
tion and disconnect jumper wire (4) from monitor coupler. NOTE:
If Suzuki scan tool cannot display DTC, perform “SERIAL
DATA LINK CIRCUIT CHECK” described in this section.
(B)(A) (C)1
NOTE:
DTC No.22 is indicated when ignition switch is ON and
engine is not running but if DTC No.12 is indicated when
engine is started, it means nothing abnormal.

INSPECTION
Step Action Yes No
1 1) Set parking brake.
2) Note combination meter when ignition
switch is turned to ON position.
Does the “BRAKE” indicator (warning lamp)
come ON?Go to Step 2.“BLK/YEL”, “BLK/WHT”
wire circuit or “IG METER”
fuse open or short to
ground.
2 1) Ignition switch OFF.
2) Remove and inspect “P/S” fuse.
Is fuse in good condition?Go to Step 3. Check “BLK/RED” wire
circuit for short to ground.
If OK, replace “P/S” fuse.
3 1) With ignition switch OFF, reinstall fuse and
disconnect P/S control module connector
(“G24”).
2) Check proper connection to P/S control
module at “G24-1” terminal.
3) If OK, check voltage between “G24-1”
(“BLK/RED” wire) terminal and body ground
with ignition switch ON.
Is it 10 – 14 V?Go to Step 4.“BLK/RED” wire circuit
open or short to ground.
4 1) Check proper connection to P/S control
module at “G24-8” terminal.
2) If OK, check voltage between “G24-8”
(“BLK/WHT” wire) terminal and body ground
with ignition switch ON.
Is it 10 – 14 V?Go to Step 5.“BLK/WHT” wire circuit
open or short to ground.
5 1) Check proper connection to P/S control
module at “G24-5” terminal.
2) If OK, check voltage between “G24-5”
(“YEL” wire) terminal and body ground with
ignition switch ON.
Is it 10 – 14 V?Substitute a known-good
P/S control module and
recheck.Go to Step 6.
6 1) Remove combination meter. Refer to “COM-
BINATION METER” in Section 8.
2) Remove and inspect “EPS” light bulb.
Is bulb in good condition?“YEL”, “BLK/WHT” wire
circuit or inside of combi-
nation meter open or
short to other circuit.Check “YEL” wire circuit
for short to ground.
If OK, replace “EPS” light
bulb.
