D—Extensive idling
E—Driving in extremely adverse weather con-
ditions or in areas where ambient tempera-
tures are either extremely low or extremely
high
F—Driving in high humidity areas or in moun-
tainous areasG—Driving in areas using salt or other corrosive
materials
H—Driving on rough and/or muddy roads or in
the desert

Checking Front Heated Oxygen Sensor
(HO2S)
Checking procedure
INSPECTION START
Start engine and warm it up until water temperature indicator points to the
middle of gauge.
1. See“M/R F/C MNT”in“Data monitor”mode.
2. Run engine at about 2,000 rpm for about 2 minutes under no-
load.
3. Maintaining engine at 2,000 rpm under no-load (engine is
warmed up sufficiently.), check that the monitor fluctuates
between“LEAN”and“RICH”more than 5 times during 10 sec-
onds.
1 time RICH→LEAN→RICH
2 times RICH→LEAN→RICH→LEAN→RICH ...
OK NG
INSPECTION END
Check and adjustment should be made by
referring to IDLE SPEED/IGNITION TIMING/
IDLE MIXTURE RATIO INSPECTION (BASIC
SERVICE PROCEDURE) in EC section.

Pull the negative-pressure valve to open it. Check that it closes
completely when released.
CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system with cap tester to check for
leakage.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher pressure than the specified value may cause damage
to radiator.
Checking Fuel Lines
Inspect fuel lines and tank for improper attachment and for leaks,
cracks, damage, loose connections, chafing and deterioration.
If necessary, repair or replace faulty parts.
Checking and Replacing Fuel Filter and
Draining Water
CHECKING FUEL FILTER
Check fuel filter for fuel leakage, damage and other abnormal
signs.
REPLACING FUEL FILTER
1. Disconnect fuel filter sensor connector and drain fuel.

2. Remove fuel filter, using a suitable tool.
3. Wipe clean fuel filter mounting surface on fuel filter bracket
and smear a little fuel on rubber seal of fuel filter.
4. Screw fuel filter on until O-ring touches mounting surface,
then tighten an additional 2/3 turn. Follow instructions on fuel
filter.
5. Install fuel filter sensor to new fuel filter.
6. Bleed air from fuel line.
7. Start engine and check for leaks.
DRAINING WATER
1. Set a container under fuel filter.
2. Loosen drain cock and drain water.
Loosening drain cock 4 to 5 turns causes water to start
draining. Do not remove drain cock by loosening it exces-
sively.
If water does not drain properly, move the priming pump up and
down.
3. Bleed air.
FUEL SYSTEM AIR BLEEDING
1. Move priming pump up and down until there is suddenly
more resistance in the movement. Then stop this action and
start the engine.
2. If engine does not operate smoothly after being started, rev
it two or three times.
When refilling empty fuel tank, bleed air out of fuel system.
Changing Air Cleaner Filter
Unfasten clamps to change air cleaner filter.
The viscous paper type filter does not need cleaning.

2. Clean the oil filter mounting surface on cylinder block. Coat
the rubber seal of the new oil filter with engine oil.
3. Screw in the oil filter until a slight resistance is felt, then
tighten an additional 2/3 turn.
4. Add engine oil.
Refer to“Changing Engine Oil”, MA-45.
Clean excess oil from engine.
Checking Injection Nozzles
1. Remove injection delivery tubes and fuel spill tube.
2. Remove nozzle assembly with S.S.T. KV119E0030.
No. 1 cylinder nozzle assembly should not be disassembled
as it is provided with a needle lift sensor.
WARNING:
When using nozzle tester, be careful not to allow diesel fuel
sprayed from nozzle to come into contact with your hand or
body, and make sure that your eyes are properly protected.
3. Clean and check nozzles.
4. Install nozzle to injection nozzle tester and bleed air from
flare nut.

REMOVAL
CAUTION:
lBefore removing the rear wheel hub assembly, discon-
nect the ABS wheel sensor from the assembly. Then
move it away from the hub assembly. Failure to do so
may result in damage to the sensor wires and the sen-
sor becoming inoperative.
lWheel hub bearing does not require maintenance. If any
of the following symptoms are noted, replace wheel hub
bearing assembly.
lGrowling noise is emitted from wheel hub bearing during
operation.
lWheel hub bearing drags or turns roughly. This occurs when
turning hub by hand after bearing lock nut is tightened to
specified torque.
