Metric Lug Nuts and Wheel Studs
All models use metric lug nuts and wheel studs.
Metric lug nuts and wheel studs size
M12 x 1.25
If broken stud or nut are found, be sure to replace both
stud and nut with new one.
Irregular and/or Premature Wear DescriptionS7RS0B2401003
Irregular and premature wear has many causes. Some
of them are as follows: incorrect inflation pressures, lack
of tire rotation, driving habits, improper alignment.
If the following conditions are noted, tire rotation is
necessary:
• Front tire wear is different from rear’s.
• Uneven wear exists across tread of any tires.
• Both sides of front tire wears are not even.
• Both sides of rear tire wears are not even.
• There is cupping, flat spotting, etc.
A wheel alignment check is necessary if following
conditions are noted:
• Both sides of front tire wears are not even.
• Wear is uneven across the tread of any front tire.
• Front tire treads have scuffed appearance with “feather” edges on one side of tread ribs or blocks.
Wear Indicators DescriptionS7RS0B2401004
Original equipment tires have built-in tread wear
indicators (1) to show when they need replacement.
These indicators (1) will app ear as 12 mm (0.47 in) wide
bands when the tire tread depth becomes 1.6 mm (0.063
in).
When the indicators (1) appear in 3 or more grooves at 6
locations, tire replacement is recommended.
I2RH01240003-01
[A]: Hard Cornering, under inflation or lack of tire rotation
[B]: Incorrect wheel alignment, tire construction not uniform or wheel heavy acceleration

Repair Instructions
General Balance ProceduresS7RS0B2406001
Deposits of mud, etc. must be cleaned from inside of rim.
WARNING!
Stones should be removed from the tread in
order to avoid operator injury during spin
balancing and to obtain good balance.

Each tire should be inspected for any damage, then
balanced according to equipment manufacturer’s
recommendation.
Off-Vehicle Balancing
Most electronic off-vehicle balancers are more accurate
than the on-vehicle spin balancers. They are easy to use
and give a dynamic (two plane) balance. Although they
do not correct for drum or disc unbalance as does on-
vehicle spin balancing, this is overcome by their
accuracy, usually to within 1/8 ounce.
On-Vehicle Balancing
On-vehicle balancing methods vary with equipment and
tool manufacturers. Be sure to follow each
manufacturer’s instructions during balancing operation.
WARNING!
Wheel spin should be limited to 55 km/h (35
mph) as indicated on speedometer.
This limit is necessary because speedometer
only indicates one-half of actual wheel speed
when one drive wheel is spinning and the
other drive wheel is stopped.
Unless care is taken in limiting drive wheel
spin, spinning wheel can reach excessive
speeds. This can result in possible tire
disintegration or differential failure, which
could cause serious personal injury or
extensive vehicle damage.

CAUTION!
Using on-vehicle balancing method with
ignition switch ON may set malfunction
diagnostic trouble code (DTC) of ESP® and
ABS even when system is in good condition.
Never turn ignition swit ch ON while spinning
wheel.

Tire RotationS7RS0B2406002
To equalize wear, rotate tires according to figure. Radial
tires should be rotated periodi cally. Set tire pressure.
[A]: Rotation direction is not indicated.
[B]: Rotation direction is indicated.

Air Bleeding of Brake SystemS7RS0B4106006
CAUTION!
Brake fluid is extremely damaging to paint. If
fluid should accidentally touch painted
surface, immediately wipe fluid from paint
and clean painted surface.

Bleeding operation is necessary to remove air whenever
it entered hydraulic brake system.
Hydraulic lines of brake system are based on the
diagonal split system. When a brake pipe or hose was
disconnected at the wheel, bleeding operation must be
performed at both ends of the line of the removed pipe or
hose. When any joint part of the master cylinder of other
joint part between the master cylinder and each brake
(wheel) was removed, the hydraulic brake system must
be bled at all 4 wheel brakes.
NOTE
Perform bleeding operation starting with rear
brake caliper farthest from master cylinder
and then at front caliper of the same brake
line. Do the same on the other brake line.

1) Fill master cylinder rese rvoir with brake fluid and
keep at least one-half full of fluid during bleeding
operation.
Brake fluid
: Refer to reservoir cap (1) 2) Remove bleeder plug cap. Attach a vinyl tube (1) to
bleeder plug, and insert the other end into container
(2).
3) Depress brake pedal several times, and then while holding it depressed, loosen bleeder plug about one-
third to one-half turn.
4) When fluid pressure in cy linder is almost depleted,
retighten bleeder plug.
5) Repeat this operation until there are no more air bubbles in hydraulic line.
6) When bubbles stop, depress and hold brake pedal and tighten bleeder plug referring to “Front Disc
Brake Components in Section 4B” and “Rear Disc
Brake Components in Section 4C”.

Front Disc Brake Pad On-Vehicle InspectionS7RS0B4206002
Inspect pad linings (1) periodically according to
maintenance schedule whenever wheels are removed
(for tire rotation or other reason). Take a look through
each end (or hole) of caliper and check lining thickness
of outside and inside pads.
If lining is worn and its thic kness (“a” in figure) is less
than limit, all pads must be replaced at the same time.
Front brake pad thickness “a” (lining thickness)
Standard: 10 mm (0.40 in.)
Limit: 2 mm (0.08 in.)

Precautions
Precautions in Diagnosing TroublesS7RS0B4500001
To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow “ABS
Check”.
• Diagnostic information stored in ABS cont rol module
memory can be cleared as well as checked by using
SUZUKI scan tool. Before us ing scan tool, read its
Operator’s (Instruction) Manual carefully to have good
understanding as to what functions are available and
how to use it.
• If the vehicles was operated in any of the following ways, ABS warning light may light momentarily but
this does not indicate anything abnormal in ABS.
– The vehicle was driven with parking brake pulled.
– The vehicle was driven with brake dragging.
– The vehicle was stuck in mud, sand, etc.
– Wheel spin occurred while driving.
– Wheel(s) was rotated while the vehicle was jacked up.
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” befo re inspection and observe
what is written there.
• Be sure to use the trouble diagnosis procedure as described in “ABS Check”. Failure to follow it may
result in incorrect diagnosis. (Some other diagnosis
trouble code may be stored by mistake in the memory
of ABS control module during inspection.)
• When disconnecting ABS co ntrol module connector
(1), pull down lock lever (2) of connector.
When connecting, set the connector on ABS control
module assembly and pull up the lock lever (2) until it
locks. • Communication of ECM,
BCM, ABS control module,
keyless start control module (if equipped), and
combination meter is established by CAN (Controller
Area Network).
Therefore, be sure to read “Precautions for Installing
Mobile Communication Equipment in Section 00”
before inspection and handle CAN communication
line.
Precautions in On-Vehicle ServiceS7RS0B4500002

General Description
ABS DescriptionS7RS0B4501001
The ABS (Antilock Brake System) controls the fluid
pressure applied to the wheel cylinder of each brake
from the master cylinder so that each wheel is not locked
even when hard braking is applied.
This ABS has also the following function.
While braking is applied, but before ABS control
becomes effective, braking force is distributed between
the front and rear so as to prevent the rear wheels from
being locked too early for better stability of the vehicle.
The main component parts of this ABS include the
following parts in addition to those of the conventional
brake system.
• Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.
• ABS warning light which light s to inform abnormality
when system fails to operate properly.
• ABS hydraulic unit / cont rol module assembly is
incorporated ABS co ntrol module, ABS hydraulic unit
(actuator assembly), solenoid valve power supply
driver (transistor), solenoid valve driver (transistor),
pump motor driver (transistor).
– ABS control module which sends operation signal to ABS hydraulic unit to control fluid pressure
applied to each wheel cylinder based on signal
from each wheel speed sensor so as to prevent
wheel from locking.
– ABS hydraulic unit which operates according to signal from ABS control module to control fluid
pressure applied to wheel cylinder of each 4
wheels.
– Solenoid valve power supp ly driver (transistor)
which supplies power to solenoid valve in ABS
hydraulic unit.
– Solenoid valve driver (transistor) which controls each solenoid valves in ABS hydraulic unit.
– Pump motor driver (transistor) which supplies power to pump motor in ABS hydraulic unit.
This ABS is equipped with Electronic Brake force
Distribution (EBD) system that controls a fluid pressure
of rear wheels to best condition, which is the same
function as that of proportion ing valve, by the signal from
wheel sensor independently of change of load due to
load capacity and so on. An d if the EBD system fails to
operate properly, the brake warning light lights to inform
abnormality.
ABS Hydraulic Unit / Control Module Assembly
Description
S7RS0B4501002
ABS control module is a component of ABS hydraulic
unit / control module asse mbly and has the following
functions.
Self-Diagnosis Function

component parts (whether or not there is any
abnormality) all the time and indicates the results
(warning of abnormality occurrence and DTC) through
the ABS warning light as described.
• When ignition switch is turned ON, ABS warning light lights for 2 seconds to check its circuit.
• When no abnormality has been detected (the system is in good condition), ABS warning light turns OFF
after 2 seconds.
• When an abnormality in th e system is detected, ABS
warning light lights and the area where that
abnormality lies is stored in the memory of EEPROM
in ABS control module.

switch ON, driving test as described is not necessary.
Proceed to Step 3.
Step 3: DTC Check
Recheck DTC referring to “DTC Check”.
Step 4: ABS Check
According to ABS Check for the DTC confirmation in
Step 3, locate the cause of the trouble, namely in a
sensor, switch, wire harness, connector, actuator
assembly or other part and repair or replace faulty parts.
Step 5: Brakes Diagnosis
Check the parts or system suspected as a possible
cause referring to “Brakes Symptom Diagnosis in
Section 4A” and based on symptoms appearing on the
vehicle (symptom obtained through Steps 1 and 2 and
repair or replace faulty parts, if any).
Step 6: Check for Intermittent Problem
Check parts where an intermittent trouble is easy to
occur (e.g., wire harness, con nector, etc.), referring to
“Intermittent and Poor Connection Inspection in Section
00” and related circuit of trouble code recorded in Step 1
to 3.
Step 7: Final Confirmation Test
Confirm that the problem symptom has gone and the
ABS is free from any abnormal conditions. If what has
been repaired is related to the malfunction DTC, clear
the DTC once referring to “DTC Clearance” and perform
test driving and confirm that no DTC is indicated.ABS Warning Light CheckS7RS0B4504002
