LEARNING PROCEDURE FOR IDLING IN
MPI ENGINE

M1001011800492

PURPOSE

When the engine-ECU <M/T> or the
engine-CVT-ECU <A/T> 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.

2. 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.

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

and stop the engine.

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

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

• Transmission: Neutral (A/T: "P" range)

• Operation in ignition-related, fan and attach-

ments: Not to be operated

• Engine coolant temperature: 80°C or more

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.

SERVICING ELECTRICAL SYSTEM

M1001011900035

CAUTION

Before connecting or disconnecting the negative
(

−) cable, be sure to turn off the ignition switch

and the lighting switch (If this is not done, there
is the possibility of semiconductor parts being
damaged).

AC300693

Before replacing a component related to the electri-
cal system and before undertaking any repair proce-
dures involving the electrical system, be sure to first
disconnect the negative (

−) cable from the battery in

order to avoid damage caused by short-circuiting.

APPLICATION OF ANTI-CORROSION
AGENTS AND UNDERCOATS

M1001011000021

If oil or grease gets onto the oxygen sensor, it will
cause a drop in the performance of the sensor.
Cover the oxygen sensor with a protective cover
when applying anti-corrosion agents and undercoats.

VEHICLE WASHING

M1001012000035

AC300832AB

Approximately 40 cm

If high-pressure car-washing equipment or steam
car-washing equipment is used to wash the vehicle,
be sure to note the following information in order to
avoid damage to plastic components, etc.

• Spray nozzle distance: Approximately 40 cm or

more

• Spray pressure: 3,900 kPa or less

• Spray temperature: 82°C or less

• Time of concentrated spray to one point: within

30 sec.

PRE-INSPECTION CONDITION

M1001012100247

"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

MULTI USE TESTER (M.U.T.-III) SUB ASSEMBLY

M1001012400099

CAUTION

For vehicles with CAN communication, use M.U.T.-III main harness A to send simulated vehicle
speed. If you connect M.U.T.-III main harness B instead, the CAN communication does not function
correctly.

IN ORDER TO PREVENT VEHICLES
FROM FIRE

M1001011100170

"Improper installation of electrical or fuel related parts
could cause a fire. In order to retain the high quality
and safety of the vehicle, it is important that any
accessories that may be fitted or modifica-
tions/repairs that may be carried out which involve
the electrical or fuel systems, must be carried out in
accordance with MMC's Information/Instructions".

ENGINE OIL

M1001011200177

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 oil, 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 oil,

particularly used engine oil.

• 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 per-
sonal clothing.

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

tion should be worn, for example, chemical gog-
gles or face shield; 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 meal (skin
cleansers and nail brushes will help). After clean-
ing, the application of preparations containing
lanolin to replace the natural skin oil 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.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

GENERAL

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

M1001009800365

The Supplemental Restraint System (SRS) and seat
belt with pre-tensioner is designed to supplement the
driver's and passenger's (front) seat belts to help
reduce the risk or severity of injury to the driver and
front passenger by activating and deploying both
front air bags in certain frontal collisions.
The SRS consist of six air bag modules, SRS air bag
control unit (SRS-ECU), front impact sensors, side
impact sensors, SRS warning lamp, clock spring and
seat belt pre-tensioner. Front air bags are located in
the centre of the steering wheel and above the glove
box. Each air bag is made up of a folded air bag and
an inflator unit. Side-airbags are located inside the
front seatback assemblies. The curtain air bag mod-
ule consists of an air bag, an inflator, and the fixing
gear relating to those parts, and is installed in the
roof side sections (from the driver's and the passen-

ger's front pillars to the rear pillars). The SRS-ECU is
located behind the floor console and has a front air
bag safing G-sensor, front air bag analogue G-sen-
sor and a side (curtain) air bag safing G-sensor. The
front impact sensor is installed on front end module.
The side impact sensor is installed in the lower parts
of the centre pillars, and contains an analogue
G-sensor. The warning lamp on the instrument panel
indicates the operational status of the SRS. The
clock spring is installed in the steering column. The
seat belt pre-tensioner is built into the driver's and
passenger's (front) seat belt retractor.
Only authorized service personnel should do work on
or around the SRS components. Those service per-
sonnel should read this manual carefully before start-
ing any such work.
