Exhaust System
General Description
Exhaust System DescriptionS7RS0B1B01001
The exhaust system consists of an exhaust manifold, three-way catalytic converter (TWC) in catalyst case, exhaust
pipes, a muffler and seals, gasket and etc.
The three-way catalytic converter is an emission control device added to the exhaust system to lower the levels of
Hydrocarbon (HC), Carbon Monoxide (CO), and Oxides of Nitrogen (NOx) pollutants in the exhaust gas.
Diagnostic Information and Procedures
Exhaust System CheckS7RS0B1B04001
WARNING!
To avoid the danger of being burned, do not touch the exhaust system when the system is hot. Any
service on the exhaust system should be performed when the system is cool.

At every interval of periodic maintenance service, and when vehicle is raised for other service, check exhaust system
as follows:
• Check rubber mountings for damage, deterioration, and out of position.
• Check exhaust system for leakage, loose connection, dent and damage.
• If bolts or nuts are loosened, tighten them to specified torque referring to “Exhaust System Components”.
• Check nearby body areas damaged, missing, or mispositio ned part, open seam, hole connection or any other
defect which could permit exhaust fumes to seep into vehicle.
• Make sure that exhaust system components have enough clearance from underbody to avoid overheating and
possible damage to passenger compartment carpet.
• Any defect should be fixed at once.

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.

Diagnostic Information and Procedures
Brakes Diagnosis NoteS7RS0B4104001
Road Testing Brakes
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both light
and heavy pedal forces at vari ous speeds to determine if
the vehicle stops evenly and effectively. Also drive
vehicle to see if it leads to one side or the other without
brake application. If it does, check the tire pressure, front
wheel alignment and front suspension attachments for
looseness. See diagnosis table for other causes. Brake Fluid Leaks
Check the master cylinder fl
uid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low leve l indicates a leak in the
system. In such a case, chec k the entire brake system
for leakage. If even a slight ev idence of leakage is noted,
the cause should be corrected or defective parts should
be replaced.
Substandard or Contaminated Brake Fluid
Improper brake fluid, mineral oil or water in the fluid may
cause the brake fluid to boil or the rubber components in
the hydraulic system to deteriorate.

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.
[A]: Disconnect C: Pull down to disconnect
[B]: Connect D: Pull up to connect
