PRECAUTIONS BEFORE SERVICE

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

CAUTION

Items to review when servicing SRS:

Be sure to read GROUP 52B - Supplemental Restraint System (SRS). For safe operation, please follow the directions and heed all warnings.

Wait at least 60 seconds after disconnecting the battery cable before doing any further work. The SRS system is designed to retain enough voltage to deploy the air bag even after the battery has been disconnected. Serious injury may result from unintended air bag deployment if work is done on the SRS system immediately after the battery cable is disconnected.

Warning labels must be heeded when servicing or handling SRS components. Warning labels can be found in the following locations.

Front impact sensor

Hood

Sun visor

Glove box

SRS-ECU

Steering wheel

Clock spring

Steering joint cover

Air bag module (Driver's or front passenger's)

Side air bag module (Driver's side or front passenger's side)

Side impact sensor

Seat belt pre-tensioner

Instrument panel

Always use the designated special tools and test equipment.

Store components removed from the SRS in a clean and dry place. The air bag module should be stored on a flat surface and placed so that the pad surface is facing upward. Do not place anything on top of it.

Never attempt to disassemble or repair the SRS components (SRS-ECU, air bag module and clock spring).

Whenever you finish servicing the SRS, check the SRS warning lamp operation to make sure that the system functions properly.

Be sure to deploy the air bag before disposing of the air bag module or disposing of a vehicle equipped with an air bag (Refer to GROUP 52B - Air Bag Module Disposal Procedures).

Observe the following when carrying out operations on places where SRS components are installed, including operations not directly related to the SRS air bag.

When removing or installing parts, do not allow any impact or shock to the SRS components.

If heat damage may occur during paint work, remove the SRS-ECU, the air bag module, clock spring, the front impact sensor, the side impact sensor, and the seat belt pre-tensioner.

SRS-ECU, air bag module, clock spring, front impact sensor, the side impact sensor: 93 °C or more

Seat belt pre-tensioner: 90 °C or more

INITIALIZATION PROCEDURE FOR LEARNING VALUE IN MPI ENGINE

INITIALIZATION PROCEDURE

After the ignition switch is in "LOCK" (OFF) position, connect MUT-II/III with the diagnosis connector.

Select the item on the screen of the initialization for learning, and perform the initialization.

Service	Item
At replacing engine assembly ^1, ²	All ranges
-*³	Misfire-related
At replacing injector and at cleaning *²	Learning value for air/fuel ratio
At replacing throttle body and at cleaning *²	Idle speed control-related
At replacing detonation sensor	Learning value for knocking

NOTE: *¹ : Initialize A/T-related learning value.

NOTE: *² : After initializing the learning value, the idling learning in MPI engine is required (Refer to LEARNING PROCEDURE FOR IDLING IN MPI ENGINE).

NOTE: *³ : The datum items on MUT-II/III display are shown, but do not use them.

SERVICING ELECTRICAL SYSTEM

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).

Before replacing a component related to the electrical system and before undertaking any repair procedures 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

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.

PRE-INSPECTION CONDITION

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

Engine coolant temperature 80 to 90°C

Lamps, electric cooling fan and all accessories: OFF

A/T: P range

VEHICLE WASHING

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: Approx. 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.

MUT-II/III

Refer to the "MUT-II REFERENCE MANUAL", "MUT-II OPERATING INSTRUCTIONS" or "MUT-III OPERATION MANUAL" for instructions on handling the MUT-II/III.

CAUTION

Turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting the MUT-II/III.

Connect the MUT-II/III to the diagnosis connector as shown in the illustration.

IN ORDER TO PREVENT VEHICLES FROM FIRE

"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 modifications/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 OILS

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 addition, 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.

Wear protective clothing, including impervious gloves where practicable.

Avoid contaminating clothes, particularly underpants, 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 clothing.

Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles 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 cleaning, 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.
