Radiator Cooling Fan Assembly On-Vehicle
Inspection
S6RW0D1606009
1) Check continuity between terminals. If there is no
continuity, replace radiator fan assembly.
2) Connect battery to radiator fan motor coupler as
shown in figure, then check that the radiator fan
motor operates smoothly. If radiator fan motor does
not operate smoothly, replace radiator fan assembly.
Reference: Fan motor specified current at 12 V
: 5.7 – 7.7 A
Radiator Cooling Fan Relay InspectionS6RW0D1606010
1) Disconnect negative (–) cable from battery.
2) Remove radiator cooling fan relay (1) from main fuse
box.
3) Check that there is no continuity between terminal
“c” and “d”. If there is continuity, replace relay.
4) Connect battery positive (+) terminal to terminal “b”
of relay and battery negative (–) terminal to terminal
“a” of relay, and then check continuity between
terminal “c” and “d”. If there is no continuity, replace
relay.

Clamp other than around fuel tank
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.
[A]: With short pipe, fit hose as far as it reaches pipe joint as shown.
[B]: With the following type pipe, fit hose as far as its peripheral projection
as shown.
[C]: With bent pipe, fit hose as its bent part as shown or till depth “b”.
[D]: With straight pipe, fit hose till depth “b”.
[E]: With red marked pipe, fit hose end reaches red mark on pipe.
[F]: For fuel tank filler hose, insert it to spool or welding-bead.
“a”: Clamp securely at a position 3 – 7 mm (0.12 – 0.27 in.) from hose end.
“b”: 20 – 30 mm (0.79 – 1.18 in.)
“c”: 0 – 5 mm (0 – 0.19 in.)
“d”: 5 – 12 mm (0.2 – 0.47 in.)
“e”: 38 mm (1.50 in.)

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 relay / fuse box cover.
Fuel Leakage Check ProcedureS6RW0D1706004
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 InspectionS6RW0D1706005
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 clamps are secure.
Replace parts as needed.
Fuel Pipe Removal and InstallationS6RW0D1706006
WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk of 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 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 clamps (1) from vehicle body, fuel pipes and
brake pipes.
CAUTION!
Be careful not to bent and damage fuel pipes
and brake pipes when removing clamp.

6) Remove fuel pipe (2).
Installation
1) Install clamps to marked location on pipes. If clamp
is deformed, its claw is bent or broken, replace it with
new one.
2) Install pipes with pipe clamps to vehicle.
3) Connect fuel hoses and pipes to each pipe referring
to “Fuel Hose Disconnecting and Reconnecting”.
4) Connect negative cable at battery.
5) With engine OFF, turn ignition switch to ON position
and check for fuel leaks.
