Precautions in Servicing 4WD ModelS6RW0D0000014
CAUTION!
• Never perform any of the following [A], [B]
and [C] types of service work.
If it is performed while 4WD-auto mode or
4WD-lock mode is selected, front wheels
(or rear wheels) drive rear wheels (or front
wheels) and vehicle accident, drivetrain
damage and personal injury may result.
Also, if it is performed while 2WD mode is
selected, the coupling may be damaged
because of the difference in revolution
speed between front wheels and rear
wheels.
• When testing with 2-wheel chassis
dynamometer or speedometer tester, be
sure to select 4WD system to 4WD-auto
mode or 4WD-lock mode and use 2-wheel
free roller together or make the vehicle as
front wheel drive by removing propeller
shaft.• When testing with 2-wheel brake tester, be
sure to observe the following instructions.
Otherwise, drivetrain damage and personal
injury may result.
– Shift transaxle to N (Neutral) position.
– Select 4WD system to 2WD mode.
– Run engine at specified idle speed.
– Rotate wheels (tires) by brake tester at
vehicle speed below 5 km/h (3 mile/h).
– Do not rotate wheels (tires) for 1 min. or
more.
• When using On-vehicle type wheel
balancing equipment (1), be sure to select
4WD system to 4WD-auto mode or 4WD-
lock mode and jack up all four wheels, off
the ground completely and support vehicle
with safety stands (2).
Be careful of other wheels, which will
rotate at the same time.
Using it with 2WD mode may damage
coupling.
• This vehicle should be towed under one of
the following conditions:
– With all wheels on a flatbed truck.
– With all wheels on the ground.

Precautions for Catalytic ConverterS6RW0D0000004
For vehicles equipped with a catalytic converter, use
only unleaded gasoline and be careful not to let a large
amount of unburned gasoline enter the converter or it
can be damaged.
• Conduct a spark jump test only when necessary,
make it as short as possible, and do not open the
throttle.
• Conduct engine compression checks within the
shortest possible time.
• Avoid situations which can result in engine misfire
(e.g. starting the engine when the fuel tank is nearly
empty.)[A]: Testing with 2-wheel chassis dynamometer or speedometer tester.
[B]: Driving front wheels, which are jacked up.
[C]: Towing under the condition where either front or rear wheels can not
rotate.

Scan Tool DataS6RW0D1104007
As the data values are standard values estimated on the basis of values obtained from the normally operating vehicles
by using a scan tool, use them as reference values. Even when the vehicle is in good condition, there may be cases
where the checked value does not fall within each specified data range. Therefore, judgment as abnormal should not
be made by checking with these data alone.
Also, conditions that can be checked by the scan tool are those detected by ECM and output from ECM as commands
and there may be cases where the engine or actuator is not operating (in the condition) as indicated by the scan tool.
Be sure to use the timing light to check the ignition timing.
NOTE
• There are two types of OBD system depending on the vehicle specification.
For identification, refer to “Precaution on On-Board Diagnostic (OBD) System”.
• With the CAN communication generic scan tool, only star (*) marked data in the following table can
be read.
• When checking the data with the engine running at idle or racing, be sure to shift M/T gear to the
neutral position and A/T gear to the “Park” position and pull the parking brake fully. Also, if nothing
or “no load” is indicated, turn OFF A/C (if equipped with A/C), all electric loads, P/S and all the other
necessary switches.

Precautions
Precautions on Fuel System ServiceS6RW0D1700001
WARNING!
Before attempting service of any type on fuel system, the following should be always observed in
order to reduce the risk of fire and personal injury.
• Disconnect negative cable at battery.
• Do not smoke, and place no smoking signs near work area.
• Be sure to have CO
2 fire extinguisher handy.
• Be sure to perform work in a well-ventilated area and away from any open flames (such as gas hot
heater).
• Wear safety glasses.
• To relieve fuel vapor pressure in fuel tank, remove fuel filler cap from fuel filler neck and then
reinstall it.
• As fuel feed line is still under high fuel pressure even after stopping engine, loosening or
disconnecting fuel feed line directly may cause dangerous spout of fuel. Before loosening or
disconnecting fuel feed line, make sure to relieve fuel pressure referring to “Fuel Pressure Relief
Procedure”.
• A small amount of fuel may be released when the fuel line is disconnected. In order to reduce the
risk of personal injury, cover a shop cloth to the fitting to be disconnected. Be sure to put that cloth
in an approved container after disconnecting.
• Never run engine with fuel pump relay disconnected when engine and exhaust system are hot.
• Note that fuel hose connection varies with each type of pipe. Be sure to connect and clamp each
hose correctly referring to “Fuel Hose Disconnecting and Reconnecting”.
After connecting, make sure that it has no twist or kink.
• When installing injector or fuel feed pipe, lubricate its O-ring with gasoline.
• When servicing the fuel tank, it should be treated with respect, with no contact with sharp edges or
hot surfaces. In addition, the fuel tank should not be dropped since fuel tank, fuel pump and other
components can be damaged by the impact. If dropped, all components should be replaced because
there is a risk of damage.
• The fuel tank is made of resin.
Be sure not to allow solvent (chemical article such as grease and sealant) to attach to the fuel tank
as some chemical reaction may occur, causing the fuel tank to be swollen, hardened or distorted
leakage and resulting in fuel leakage from the fuel tank.

General Description
Fuel System DescriptionS6RW0D1701001
CAUTION!
This engine requires the unleaded fuel only.
The leaded and/or low lead fuel can result in
engine damage and reduce the effectiveness
of the emission control system.

The main components of the fuel system are fuel tank,
fuel pump assembly (with fuel filter, fuel level gauge, fuel
pressure regulator), fuel feed line and fuel vapor line.
For the details of fuel flow, refer to “Fuel Delivery System
Diagram”.
Fuel Delivery System DescriptionS6RW0D1701002
The fuel delivery system consists of the fuel tank, fuel
pump assembly (with built-in fuel filter and fuel pressure
regulator), delivery pipe, injectors and fuel feed line.
The fuel in the fuel tank is pumped up by the fuel pump,
sent into delivery pipe and injected by the injectors.
As the fuel pump assembly is equipped with built-in fuel
filter and fuel pressure regulator, the fuel is filtered and
its pressure is regulated before being sent to the feed
pipe.
The excess fuel at fuel pressure regulation process is
returned back into the fuel tank.
Also, fuel vapor generated in fuel tank is led through the
fuel vapor line into the EVAP canister.
For system diagram, refer to “Fuel Delivery System
Diagram”.
Fuel Pump DescriptionS6RW0D1701003
The fuel pump (1) is an in-tank type electric pump.
Incorporated in the pump assembly are;
a fuel filter (2), a fuel pressure regulator (3) and a fuel
level sensor (gauge) (4).

For Quick Joint
Disconnecting
1) Remove mud, dust and/or foreign material between
pipe (1) and quick joint (fuel pipe) (2) by blowing
compressed air.
2) Unlock joint lock by inserting special tool between
pipe and quick joint.
Special tool
(A): 09919–47020
3) Disconnect quick joint from pipe.
Reconnecting
Insert quick joint (fuel pipe) to fuel pipe until they lock
securely (a click is heard), and confirm that quick joint
(fuel pipe) is not disconnected by hand.
Fuel Pressure Relief ProcedureS6RW0D1706003
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 filler cap in order to release fuel vapor
pressure in fuel tank, and then reinstall it.
