Diagnostic Information and Procedures
Battery InspectionS7RS0B1A04001
Common Causes of Failure
A battery is not designed to last indefinitely; however, with proper care, it will provide many years of service. If the
battery performs satisfactorily during te st but fails to operate properly for no apparent reason, the following are some
factors that may point to the cause of trouble:
• Accessories left on overnight or for an extended period without the generator operating.
• Slow average driving speeds for short periods.
• Electrical load exceeding generator output partic ularly with addition of aftermarket equipment.
• Defects in charging system such as high resistance, s lipping drive belt, loose generator output terminal, faulty
generator or voltage regulator, Refer to “Generator Symptom Diagnosis”.
• Battery abuse, including failure to keep battery cable terminals clean and tight or loose battery hold down.
• Mechanical problems in electrical sys tem such as shorted or pinched wires.
Visual Inspection
Check for obvious damage, such as cracked or broken case or cover, that could permit loss of electrolyte. If obvious
damage is noted, replace battery. Determine cause of damage and correct as needed.
Generator Symptom DiagnosisS7RS0B1A04002
CAUTION!
• Do not mistake polarities of “IG” terminal and “L” terminal.
• Do not create short circuit between “IG” and “L” terminals. Always connect these terminals through a lamp.
• Do not connect any load between “L” and “E” terminals.
• When connecting charger or booster battery to vehicle battery, refer to “Jump Starting in Case of Emergency”.

Trouble in charging system will show up as one or more of the following conditions:
1) Faulty indicator lamp operation.
2) An undercharged battery as evidenced by slow cranking or indicator dark.
3) An overcharged battery as evidenced by ex cessive spewing of electrolyte from vents.
Condition Possible cause Correction / Reference Item

Downloaded from www.Manualslib.com manuals search engine Wheels and Tires: 2D-6
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.

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
When connector is connected to ABS control module
assembly, do not disconnect connectors of sensors with
ignition switch ON. Otherwise, DTC will be set in ABS
control module.
Precautions in Hydraulic Unit Operation CheckS7RS0B4500003
ABS hydraulic unit / control module assembly function is
checked by correct wheel lock / release condition when
brake pressure is pressurized / depressurized using
SUZUKI scan tool. The hydraulic unit operation check
referring to “ABS Hydraulic Unit Operation Check”
should be performed to confirm the correct brake pipe
connection in the following cases.
• ABS hydraulic unit / cont rol module assembly was
replaced.
• Brake pipe and/or hose ware replaced.

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
ABS control module diagnose s conditions of the system
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.
