30. CHECK FOR FUEL LEAKS
NOTICE:
Under ACTIVE TEST mode, fuel pressure increases. Take precautions to prevent fuel from spraying
on you or inside the engine compartment.
HINT:
During ACTIVE TEST mode, engine speed goes high and combustion noise bec\
omes loud.
(a) Check that there are no fuel leaks from any part of the fuel system at t\
he engine stops.
HINT:
If fuel leakage could be found on specific parts, replace them with new \
parts.
(b) While cranking or when starting the engine, check that there is no leaks from\
any part of the fuel sys-
tem.
HINT:
If fuel leakage could be found on specific parts, replace them with new pa\
rts.
(c) Disconnect the fuel hose from the common rail.
(d) While cranking the engine, check fuel leaks from the return pipe.
HINT:
If there is fuel leakage, replace the common rail.
(e) Connect the hand±held tester to the DLC3.
(f) Start the engine and push the hand±held tester main switch ON.
(g) Select the FUEL LEAK test of ACTIVE TEST mode on the hand±held tester\
.
(h) If you do not have the hand±held tester, depress the accelerator pedal quickly and fully to increase the engine speed at maximum and keep it for 2 seconds. Repeat this opera\
tion several times.
(i) Check that there are no leaks from any part of the fuel system.
NOTICE:
If the leakage from the return pipe is less than 10 cc (0.6 cu in.) in\
a minute, it is acceptable.
HINT:
If fuel leakage could be found on specific parts, replace them with new \
parts.
(j) Reconnect the fuel hose to the common rail.

the heated oxygen sensor again.
2. INSPECT FUEL CUT OFF RPM
(a) Increase the engine speed to at least 3,500 rpm.
(b) Use a sound scope to check for injector operating sounds.
(c) Check that the injector operating sounds stops momentarily and then resumes that when the throttle
lever is released.
3. INSPECT EVAPORATIVE EMISSION CONTROL SYS-
TEM
(a) After starting the engine, disconnect the vacuum hose
shown in the illustration.
(b) Check if vacuum occurs at the VSV port when choosing
ºACTIVE TESTº and ºPURGE VSVº according to the dis-
play on hand±held tester.
(c) Finish ºACTIVE TESTº, then reconnect the vacuum hose.
(d) After entering to ºECU DATA MONITORº on the hand±
held tester, choose ºPURGE VSVº to check the operation

TURBO CHARGER SYSTEM (1CD±FTV)
PRECAUTION
1. MAINTENANCE PRECAUTION
(a) Do not stop the engine immediately after pulling a trailer,
or after driving at a high speed, or uphill drive. Let the en-
gine Idle for 20 to 120 seconds before turn the ignition
switch OFF (According as the driving condition, the idling
time varies).
(b) Avoid quick acceleration or quickly accelerating the en-
gine RPM immediately after the starting a cold engine.
(c) If the turbocharger is found to be defective, it must be re-
placed. Also, inspect a source of the trouble including
conditions of the turbocharger that having been used. Re-
pair or replace the followings as necessary:
(1) Engine oil (Level and quality)
(2) Oil lines leading to the turbocharger
(d) Pay due attention when removing and reinstalling the
turbocharger assembly. Do not drop, or do not give shock,
or do not grasp easily±deformed assembly parts such as
the actuator or push rod in removal and reinstallation.
(e) Before removal, cover both the intake and exhaust ports
and the oil inlet to prevent dirt or foreign objects from be-
ing introduced.
(f) If replacing the turbocharger, check for deposits in the oil
pipe. If necessary, replace the oil pipe too.
(g) Thoroughly remove old gasket sticking to the lubrication
oil pipe flange and the turbocharger oil flange.
(h) If replacing the bolt(s) or nut(s), must use Toyota genuine
parts to prevent breakage or deformation.
(i) If replacing the turbocharger, put 20 cm
3 (1.2 cu in.) of
fresh oil into the turbocharger oil inlet hole and turn the tur-
bine wheel by hand to spread oil to the bearing.
(j) If overhauling or replacing the engine, cut the fuel supply
after reassembly and crank the engine for 30 seconds to
feed oil throughout the engine then run the engine at idle
for 60 seconds.

EGR SYSTEM (1CD±FTV)
ON±VEHICLE INSPECTION
HINT:
In a malfunction where the EGR system is always on, black smoke or white smoke may be emitted from the
exhaust pipe. If this occurs, inspect the EGR system as well.
1. INSPECT SEATING OF EGR VALVE
(a) Start the engine and check that it starts and runs at idle.
2. INSPECT HOT ENGINE CONDITION (WHEN USING HAND±HELD TESTER)
(a) Connect the hand±held tester to the DLC3.
(b) Start the engine and run it at idle.
(c) Select the ACTIVE TEST mode on the hand±held tester.
HINT:
Refer to the hand±held tester operator's manual for further details.
(d) Warm up the engine, the coolant temperature should be above 75
C (109
F) and bellow 90
C
(194
F).
(e) Check that the AFM reading is 5
ega
8 g/s with the engine idling.
(f) Operate the EGR valve with a hand±held tester. Regulate the valve opening angle to 0, and check that
the AFM reading is 11
ega
17 g/s..
If the AFM reading is out of range in either (e) or (f), replace the EGR valve.
If the AFM is out of range in both (e) and (f), replace the air flow meter (air cleaner) and check the EGR valve
operation again.
3. INSPECT HOT ENGINE CONDITION (WHEN NOT USING HAND±HELD TESTER)
(a) Install the vacuum gauge.
(1) Using a 3±way connector, connect a vacuum gauge to the hose between the intake manifold and
the turbo pressure sensor.
(b) Warm up the engine, the coolant temperature should be above 75
C (109
F) and bellow 90
C
(194
F).
(c) Check that the vacuum gauge indicates about more than 2.5 kPa (19 mmHg 0.7 in Hg).
(d) Stop the engine (IG OFF), remove the EGR valve connector, restart the engine, and check that load
under idling is less than 2.5 kPa (19 mmHg 0.7 in Hg).
If the load pressure exceeds the above value, replace the EGR valve.
