Fuel Pressure Relief ProcedureS7RS0B1706003
CAUTION!
This work must not be done when engine is
hot. If done so, it may cause adverse effect to
catalyst.
NOTE
If ECM detects DTC(s) after servicing, clear
DTC(s) referring to “DTC Clearance in
Section 1A”.
1) Make sure that engine is cold.
2) Shift transaxle gear shift lever in “Neutral” (shift select lever in “P” range for A/T model), set parking
brake and block drive wheels.
3) Remove relay / fuse box cover.
4) Disconnect fuel pump relay (1) from relay / fuse box (2).
5) Remove fuel filter cap in order to release fuel vapor pressure in fuel tank, and then reinstall it.
6) Start engine and run it until engine stops for lack of fuel. Repeat cranking engine 2 – 3 times for about 3
seconds each time in order to dissipate fuel pressure
in lines. Fuel connections are now safe for servicing.
7) After servicing, connect fuel pump relay (1) to relay / fuse box and install re lay / fuse box cover.
Fuel Leakage Check ProcedureS7RS0B1706004
After performing any service on fuel system, check to
make sure that there are no fuel leakages as follows.
1) Turn ON ignition switch for 3 seconds (to operate fuel pump) and then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply
fuel pressure to fuel line until fuel pressure is felt by
hand placed on fuel feed hose.
2) In this state, check to see that there are no fuel leakages from any part of fuel system.
Fuel Lines On-Vehicle InspectionS7RS0B1706005
CAUTION!
Due to the fact that fuel feed line (1) is under
high pressure, use special care when
servicing it.
Visually inspect fuel lines for evidence of fuel leakage,
hose crack and deterioration or damage.
Make sure all cl amps are secure.
Replace parts as needed.
Fuel Pipe Removal and InstallationS7RS0B1706006
WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk or fire
and personal injury.
Removal
1) Relieve fuel pressure in fuel feed line according to “Fuel Pressure Relief Procedure”.
2) Disconnect negative cable at battery.
3) Disconnect fuel pipe joint and fuel hose (3) from fuel pipe (2) at the front and rear of each fuel pipe
referring to “Fuel Hose Disconnecting and
Reconnecting”.
4) Mark the location of clamps (1) on fuel pipes (2), so that the clamps can be reinstalled to where they
were.
5) Remove pipes (2) with clamp (1) from vehicle.
6) Remove clamp (1) from pipes (2).

4) Install suitable vinyl tube onto injector nozzle to
prevent fuel from splashing out when injecting.
5) Put graduated cylinder under injector.
6) Operate fuel pump and apply fuel pressure to
injector as follows:
a) When using scan tool:
i) Connect scan tool to DLC with ignition switch OFF.
ii) Turn ignition switch ON, clear DTC and select “MISC TEST” mode on scan tool.
iii) Turn fuel pump ON by using scan tool.
Special tool
(A): SUZUKI scan tool
b) When not using scan tool: i) Remove fuel pump relay from connector.
ii) Connect two terminals of relay connector using service wire (1) as shown in figure.
CAUTION!
Check to make sure that connection is made
between correct terminals. Wrong
connection can cause damage to ECM, wire
harness, etc.
iii) Turn ignition switch ON. 7) Apply battery voltage to in
jector (1) for 15 seconds
and measure injected fuel volume with graduated
cylinder. Test each injector two or three times. If not
within specification, replace injector.
Injected fuel volume
43 – 47 cc/15 sec. (1.45/1.51 – 1.58/1.65 US/lmp
oz/15 sec.)
8) Check fuel leakage from injector nozzle. Do not operate injector for this check (but fuel pump should
be at work). If fuel leaks (1) more than the following
specifications, replace.
Fuel leakage
Less than 1 drop/min.
Fuel Filler Cap InspectionS7RS0B1706010
WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk or fire
and personal injury.
Remove cap (1), and che ck gasket for even filler neck
imprint, and deterioration or any damage. If gasket (2) is
in malcondition, replace cap.
NOTE
If cap requires replacement, only a cap with
the same features should be used. Failure to
use correct cap can result in fire and
personal injury.

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