been removed from the vehicle, please refer to sepa
rate manuals covering the engine and the transmission.
ON-VEHICLE SERVICE
"On-vehicle Service" is procedures for performing
inspections and adjustments of particularly important
locations with regard to the construction and for
maintenance and servicing, but other inspection (for
looseness, play, cracking, damage, etc.) must also
be performed.
INSPECTION
Under this title are presented inspection and checking procedures to be performed by using special
tools and measuring instruments and by feeling, but,
for actual maintenance and servicing procedures,
visual inspections should always be performed as
well.
DEFINITION OF TERMS

adjustment procedures, and so they can be com
pleted in a shorter time).
DANGER, WARNING, AND CAUTION
DANGER, WARNING, and CAUTION call special
attention to a necessary action or to an action that
must be avoided. The differences among DANGER,
WARNING, and CAUTION are as follows:
• If a DANGER is not followed, the result is severe
-
bodily harm or even death.
• If a WARNING is not followed, the result could be
bodily injury.
• If a CAUTION is not followed, the result could be
damage to the vehicle, vehicle components or
service equipment.

CAUTION
During diagnosis, a diagnosis code associated
with other system may be set when the ignition
switch is turned on with connector(s) discon
nected. On completion, confirm all systems for
diagnosis code(s). If diagnosis code(s) are set,
erase them all.
WARNING
Since the radiator fan rotates during CAN
bus line diagnostics, make sure that no one
is servicing the engine compartment before
diagnosing the CAN bus line. Since the CAN
communication stops when diagnosing the
CAN bus line, the ETACS-ECU detects the
time-out of the engine-ECU, and activates
the radiator fan to prevent overheating as
fail-safe.
Troubleshooting of electronic control systems for
which the M.U.T.-III can be used follows the basic
outline described below. Even in systems for which
the M.U.T.-III cannot be used, some of these sys
tems still follow this outline.

A
Remove the blown fuse and measure the resistance
between the load side of the blown fuse and the
earth. Close the switches of all circuits which are
connected to this fuse. If the resistance is almost 0
Ω
at this time, there is a short somewhere between
these switches and the load. If the resistance is not 0
Ω, there is no short at the present time, but a
momentary short has probably caused the fuse to
blow.
The main causes of a short circuit are the following.
• Harness being clamped by the vehicle body
• Damage to the outer casing of the harness due to
wear or heat
• Water getting into the connector or circuitry
• Human error (mistakenly shorting a circuit, etc.)
AC300901
Intermittent malfunctions often occur under certain
conditions, and if these conditions can be ascer
tained, determining the cause becomes simple. In
order to ascertain the conditions under which an
intermittent malfunction occurs, first ask the cus
tomer for details about the driving conditions,
weather conditions, frequency of occurrence and
trouble symptoms, and then try to recreate the trou
ble symptoms. Next, ascertain whether the reason
why the trouble symptom occurred under these con
ditions is due to vibration, temperature or some other
factor. If vibration is thought to be the cause, carry
out the following checks with the connectors and
components to confirm whether the trouble symptom
occurs. The objects to be checked are connectors
and components which are indicated by inspection
procedures or given as probable causes (which gen
erates diagnosis codes or trouble symptoms).

HEALTH WARNING
Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi
tion, used engine oil contains potentially harmful contaminants which may cause skin cancer. Adequate
means of skin protection and washing facilities must
be provided.
RECOMMENDED PRECAUTIONS
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example by
using enclosed systems for handling used engine oil
and by degreasing components, where practicable,
before handling them.
Other precautions:
• Avoid prolonged and repeated contact with oils,
particularly used engine oils.
• Wash regularly with soap and water to ensure all
pants, with oil.
• Do not put oily rags in pockets, the use of overalls
without pockets will avoid this.
• Do not wear heavily soiled clothing and oilimpregnated foot-wear. Overalls must be cleaned
regularly and kept separately from personal cloth
ing.
• Do not use petrol, kerosine, diesel fuel, gas oil,

)
)
)
GENERAL
PRECAUTIONS BEFORE SERVICE
For this reason, when the injector or engine-ECU is
replaced, injector correction data must be registered
afterwards in the engine-ECU using the Multi Use
Tester III (M.U.T.-III).
Correction data is converted into an identification
code consisting of 30 alphanumeric characters and
printed on the injector connector.
REGISTRATION PROCEDURE
1. When replacing the engine-ECU, connect the
current engine-ECU to the body harness.
NOTE: This operation is purposed to read the injector identification code stored in the engine-ECU.
Reading the identification code in this way before
replacement can eliminate manual input of the identi
fication code after replacement.
2. After the ignition switch is in "LOCK" (OFF)
position, connect the M.U.T.-III to the diagnosis
connector.
3. Turn the ignition switch to "ON" position.
4. Select SPECIAL FUNCTION from the function
menu.
5. When the current engine-ECU is still mounted,
read and register the injector identification code
as follows:
(1) Select Read Injector ID Code (for engine-ECU
replacement) from the SPECIAL FUNCTION
menu.
(2) Select Write and Save Injector ID Code from
the menu to read data from the current engineECU and save the data if it could be read
normally.
(3) Mount the new engine-ECU on the vehicle.
(4) Select SPECIAL FUNCTION from the function
menu.
(5) Select Write Injector ID Code (for engine-ECU
replacement) from the SPECIAL FUNCTION
menu.
(6) Select SAVED INJECTOR ID WRITING from
the Write Injector ID Code menu to write the
data, which was saved previously, to the
engine-ECU.
6. If the injector has been replaced or data has not
been read from the current engine-ECU, register
the injector identification code as follows:
(1) Select Write Injector ID Code from the
SPECIAL FUNCTION menu.
(2) If the injector was replaced, specify whether to
write to every cylinder or a specific cylinder.

CAUTION
Even if the number of the cylinder to be registered does not match the actual injector mounting location, registration ends normally. Specify
the cylinder number correctly.
NOTE: The identification code is displayed in order
of the frame numbers when it is read.
7. Makes sure that the engine warning lamp that is
on changes to blinking, indicating the registration
is complete.
NOTE: When the injector is replaced, executing the
write operation also clears the values of small injec
tion quantity learning.
8. Execute small injection quantity learning.
Refer to P.00-45, the SMALL INJECTION
QUANTITY LEARNING PROCEDURE for the
learning procedure.
9. Confirm that the engine warning lamp is off.
Confirm also that the diagnosis code is not stored.

GENERAL
PRECAUTIONS BEFORE SERVICE
SMALL INJECTION QUANTITY LEARNING PROCEDURE
CAUTION
1. If small injection quantity learning has not
been executed, the engine warning lamp
blinks.
2. When the requirements for learning are satis-
fied by operation after replacement of the
engine-ECU, learning is automatically exe
cuted even if no instruction is given from the
M.U.T.-III. Accordingly, the malfunction indica
tor lamp goes off. However, the learning thus
executed is tentative and limited. Be sure to
complete leaning using the M.U.T.-III.
-
PURPOSE
To keep emission and noise level at adequate levels,
the engine-ECU must learn injector fuel injection in
idle mode.
During learning, the engine-ECU calculates actual
injection from each cylinder based on changes in
engine speeds and corrects pilot injection control. It
then keeps records of this amount of correction as a
learned value.
For this reason, after the engine-ECU or injector is
replaced, learning must be executed using the
M.U.T.-III.
NOTE: Engine friction changes or injector deterioration over time may cause fluctuation in pilot injection.
After use over time, it may prevent injection of an
accurate amount of fuel according to the indication
by the engine-ECU. This is why learning must be
executed again periodically.
For this reason, the engine-ECU periodically leans
injection according to the cumulative mileage.
Note that making the M.U.T.-III learn again resets the
cumulative mileage.
NOTE: The engine sound may change or idling
engine speeds may increase during injection learn
ing. These are not abnormalities.
LEARNING PROCEDURE
1. After the ignition switch is in "LOCK" (OFF)
position, connect the M.U.T.-III to the diagnosis
connector.
-
2. Put the vehicle in the following idling stable
conditions:
• Engine coolant temperature: 80 − 90°C
• Fuel temperature: 30 − 100°C
• Intake air temperature: −30 to 100°C
• Barometric pressure: 70 kPa or more
• Automatic transmission fluid temperature: 60°C
or higher
• Lamps, A/C condenser fan and all accessories:
OFF
• Transmission: Neutral <M/T>, "P" range <A/T>
• Power steering: Static state
3. Select SPECIAL FUNCTION from the function
menu.
4. Select LEARNING from the SPECIAL FUNCTION
menu.
5. Select Item No. 1 Small injection quantity learning
to execute learning.
CAUTION
If the vehicle conditions go out of the learning
conditions during idling, learning is interrupted.
To reexecute learning, the ignition switch
must once be turned off.
6. Continue idling for about 3 minutes before
learning is completed.
7. Confirm that the engine warning lamp is off. If it
still blinks, reexecute learning.

SUPPLY PUMP CORRECTION LEARNING PROCEDURE
PURPOSE
The engine-ECU learns the relation between the
suction control valve (linear solenoid valve) of the
supply pump drive current and the fuel injection vol
ume.
The learning value is calculated from the suction
control valve drive current and the rail pressure sen
sor output voltage.
When the supply pump is replaced, therefore, this
learning must be executed.
Re-learning is executed when the engine is idling
after the learning value in the engine-ECU has been
reset by the M.U.T.-III.
