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
Noisy generator Loose drive belt Adjust or replace drive belt.
Loose drive belt pulley Tighten by specified torque.
Loose mounting bolts Tighten by specified torque.
Worn or dirty bearings Replace.
Defective diode or stator Replace.
Charge light does not

Precautions
Precaution for Emergency Flat Tire Repair KitS7RS0B2400001
WARNING!
Flat tire repair sealant including in kit is
harmful. Be sure to observe the following.
Otherwise, your health may be ruined.
• If swallowed, get medical attention immediately.
• Keep out of reach of children.
• Select place where there is good ventilation for this work.
• If it enters eye or contacts skin, wash thoroughly with water. If anything
abnormal still rema ins, get medical
attention immediately.
• Do not discard tire containing sealant as it is. Make sure to remove sealant from tire,
referring to “Tire Repair for Emergency
Repaired-Tire with Sealant”.
• Dispose of sealant as waste oil.

CAUTION!
• When tire repaired with Emergency Flat Tire Repair Kit is brought in, remove flat
tire repair sealant from tire and repair flat
tire referring to “Tire Repair for Emergency
Repaired-Tire with Sealant”.
• Sealant expiration date is printed on bottle label. if it expires, sealant should be
replaced with a new one to ensure
emergency flat tire repair.

General Description
Tires DescriptionS7RS0B2401001
The tire is of tubeless type. The tire is designed to
operate satisfactorily with loads up to the full rated load
capacity when inflated to the recommended inflation
pressures.
Correct tire pressures and driving habits have an
important influence on tire life. Heavy cornering,
excessively rapid acceleration, and unnecessary sharp
braking increase tire wear.
Tire Placard
The “Tire Placard” is located on the left or right door lock
pillar and should be referred to tire information.
The placard lists the maximum load, tire size and cold
tire pressure where applicable.
NOTE
Whether rim size and/or maximum load are
listed or not depends on regulations of each
country.

Inflation of Tires
The pressure recommended for any model is carefully
calculated to give a satisfacto ry ride, stability, steering,
tread wear, tire life and resistance to bruises.
Tire pressure, with tires cold, (after vehicle has set for 3
hours or more, or driven less than one mile) should be
checked monthly or before any extended trip. Set to the
specifications on the “Tire Placard” located on the left
door lock pillar.
It is normal for tire pressure to increase when the tires
become hot during driving.
Do not bleed or reduce tire pressure after driving.
Bleeding reduces the “Cold Inflation Pressure”.
Higher than recommended pressure can cause:
• Hard ride
• Tire bruising or carcass damage
• Rapid tread wear at center of tire
Unequal pressure on same axle can cause:
• Uneven braking
• Steering lead
• Reduced handling
• Swerve on acceleration

DTC ClearanceS7RS0B4504006
WARNING!
When performing a driving test, select a safe
place where there is neither any traffic nor
any traffic accident possibility and be very
careful during testing to avoid occurrence of
an accident.

After repair or replace malfunction part(s), clear all DTCs
by performing the following procedure or using SUZUKI
scan tool.
1) Connect SUZUKI scan tool to data link connector in the same manner as when making this connection
for DTC check.
2) Turn ignition switch to ON position.
3) Erase DTC according to instructions displayed on scan tool. Refer to scan tool operator’s manual for
further derails.
NOTE
For DTC C 1021, C1022, C1025, C1026, C1031,
C1032, C1035, C1036 and C1061, confirm that
ABS warning light turns off after performing
Step 2 of “Test Driving” under “ABS Check”,
and then clear the DTCs.

4) After completing the clear ance, turn ignition switch
OFF and disconnect scan tool from data link
connector.
5) Perform “Driving Test” (S tep 2 of “ABS Check”) and
“DTC Check” and confirm that NO DTC is displayed
on scan tool.
Scan Tool DataS7RS0B4504007
The parameter data below are values measured with the
scan tool when the normally operating vehicle is under
the following conditions. When taking measurements for
comparison by using the scan tool, be sure to check that
the vehicle is under the following conditions.
• Apply parking brake and block wheels.
• Ignition switch ON.
• Turn OFF air conditioner (if equipped).
• Apply no load to power steering (if equipped). (Don’t turn it)
• Turn OFF all electric loads (except ignition).
• No DTC.
• ABS is not operated. (N ormal braking operation)
Scan Tool Data Definition
Battery Volt (V): Battery Voltage is an analog input
signal read by the ABS control module. Certain ABS
control module function s will be modified if the
battery voltage falls below or rises above
programmed thresholds.
Pump Motor Driver (V): This parameter indicates the
operational condition of the pump motor driver
(transistor).
RF Wheel Speed, LF Wheel Speed, RR Wheel Speed and LF Wheel Speed (km/h, MPH): Wheel speed
is an ABS control module inte rnal parameter. It is
computed by reference pulses from the wheel speed
sensor.
Brake Switch (ON, OFF): This switch signal informs
the ABS control modu le whether the brake is active
or not.
