PRECAUTIONS BEFORE SERVICE

GENERAL

NOTE:

•

: The setting can be changed by the option cod-

ing.

OPTION CODING

CAUTION

• If there is any item indicated by the option

coding after equipment change, set ETACS-
ECU so that the option coding data corre-
sponds with the equipment content. Pay
attention to that the concerned functions and
systems do not work normally if the setting
does not correspond with the equipment.

• With the ETACS functions being customised,

if any of the ETACS-ECU option coding items
are changed, the customised contents are
reset. In such case, the functions need to be
recustomised.

The engine-ECU <4A9, 4B1, 4J1> or ETACS-ECU
option coding data can be checked or changed by
operating M.U.T.-III.

• How to check option coding data

1. Connect the M.U.T.-III. Refer to .
2. Select "MPI/GDI/DIESEL" <4A9, 4B1, 4J1> or

"ETACS" on the system selection screen.

3. Select "Coding."

4. Select "Option Coding Information."
5. Check the displayed option coding informa-

tion.

• How to change option coding data

1. Connect the M.U.T.-III. Refer to .
2. Select "MPI/GDI/DIESEL" <4A9, 4B1, 4J1> or

"ETACS" on the system selection screen.

3. Select "Coding."
4. Select "Option Coding."
5. Change to correct option coding data.

PRECAUTIONS BEFORE SERVICE

GENERAL

PRE-INSPECTION CONDITION

M1001012100731

"Pre-inspection condition" refers to the condition that
the vehicle must be in before proper engine inspec-
tion can be carried out. If you see the words "Set the
vehicle to the pre-inspection condition". In this man-
ual, it means to set the vehicle to the following condi-
tion.

• Engine coolant temperature 80 to 90°C

• Lamps, electric cooling fan and all accessories:

OFF

• M/T: Neutral

• A/T: P range

• CVT: P range

• TC−SST: P range

ENGINE OILS

M1001011200230

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 con-
taminants 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.

• Wear protective clothing, including impervious

gloves where practicable.

• Avoid contaminating clothes, particularly under-

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 oil-

impregnated foot-wear. Overalls must be cleaned
regularly and kept separately from personal cloth-
ing.

• Where there is a risk of eye contact, eye protec-

tion should be worn, for example, chemical gog-
gles or face shields; in addition an eye wash
facility should be provided.

• Obtain first aid treatment immediately for open

cuts and wounds.

• Wash regularly with soap and water to ensure all

oil is removed, especially before meals (skin
cleansers and nail brushes will help). After clean-
ing, the application of preparations containing
lanolin to replace the natural skin oils is advised.

• Do not use petrol, kerosine, diesel fuel, gas oil,

thinners or solvents for cleaning skin.

• Use barrier creams, applying them before each

work period, to help the removal of oil from the
skin after work.

• If skin disorders develop, obtain medical advice

without delay.

INITIALISATION PROCEDURE FOR
LEARNING VALUE IN MPI ENGINE

M1001011701476

Initialise learning values in the MPI engine when one
of the following service operations is performed.

• At replacing engine assembly.

• At replacing and cleaning injector.

• At replacing and cleaning throttle body.

• At replacing detonation sensor.

• At replacing, installing and removing valve lift

sensor. <4J1>

• At replacing, installing and rocker arm and cam-

shaft assembly. <4J1>

NOTE: *: Initialise A/T or CVT related learning value.

CAUTION

To prevent damage to M.U.T.-III, always turn the
ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting M.U.T.-III.
1. After the ignition switch is in "LOCK" (OFF)

position, connect the M.U.T.-III to the diagnosis
connector.

2. Turn the ignition switch to the "ON" position.

3. Select "MPI/GDI/DIESEL" from System select

Screen of the M.U.T.-III.

4. Select "Special Function" from MPI/GDI/DIESEL

Screen.

5. Select "Learned value reset" from Special

Function Screen.

6. Select "All learned value" from Learned value

reset Screen

7. Initialise the learning value by pressing the "OK"

button.

8. After initialising the learning value, the learning

value of MPI engine idling is necessary. (refer to
Learning Procedure for Idling in MPI Engine

P.00-

LEARNING PROCEDURE FOR IDLING IN
MPI ENGINE

M1001011801417

PURPOSE

When the engine-ECU is replaced, or when the
learning value is initialised, the idling is not stabilized
because the learning value in MPI engine is not com-
pleted. In this case, carry out the learning method for
the idling through the following procedures.

LEARNING PROCEDURE

1. Start the engine and carry out the warm-up for the

engine coolant temperature to reach 80

°C or

more.
When the engine coolant temperature is 80

°C or

more, the warm-up is not needed if the ignition
switch is in "ON" position once.

2. Place the ignition switch in "LOCK" (OFF) position

and stop the engine.

3. After 10 seconds or more, start the engine again.
4. For 10 minutes, carry out the idling under the

condition shown below and then confirm the
engine has the normal idling.

• Transmission: Neutral <M/T> or "P" range <A/T,

CVT or TC-SST>

• Operation in lamps, fan and attachments: Not to

be operated

• Engine coolant temperature: 80°C or more

• CVT fluid temperature: 60°C or more <4J1>

NOTE: When the engine stalls during the idling,
check the dirtiness (on the throttle valve) of the
throttle body and then perform the service from
Procedure 1 again.

PRECAUTIONS BEFORE SERVICE

GENERAL

00-60

INITIALISATION PROCEDURE FOR
THROTTLE VALVE CONTROL SERVO

Disconnecting and reconnecting the battery cables
causes the throttle valve closed-position value
learned to be erased from the memory. This may
prevent the idle speed control from being executed
properly. When the battery cables have been discon-
nected and reconnected, initialise the throttle valve
control servo in the following manner.
1. Turn the ignition switch to "ON" and then to

"LOCK" (OFF).

2. Keep the ignition switch in "LOCK" (OFF) for at

least 10 seconds.

SERVICING COMMON RAIL ENGINE
<4N1>

M1001016400176

DANGER

•

The working near to a naked flame or
sparks must be avoided.

•

Attention during engine running:

Do not work on the high pressure fuel
circuit.

Always remain out of the way of possi-
ble fuel jet that may result in serious
injuries.

Do not place your hand near the high
pressure fuel circuit.

•

Attention before service:

After turning the ignition switch to the
"LOCK" (OFF) position, wait for 30 sec-
onds before starting any repair work.
This period of time is required so that
the high pressure fuel circuit pressure
can get back to the atmospheric pres-
sure.

WHAT THE COMMON RAIL ENGINE LEARNS <4N1>

M1001012500245

After fuel-related parts are replaced, the common rail
engine must register their identification codes with
the engine-ECU and execute learning.
The table below shows what should be registered
and learned after each type of operation.

NOTE: When the engine-ECU is replaced, collect in
advance the injector identification code from the cur-
rent engine-ECU. Doing it makes registration easy.
