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:
DAvoid prolonged and repeated contact with oils, particularly used engine oils.
DWear protective clothing, including impervious gloves where practicable.
DAvoid contaminating clothes, particularly underpants, with oil.
DDo not put oily rags in pockets, the use of overalls without pockets will avoid this.
DDo not wear heavily soiled clothing and oil-impregnated foot-wear. Overalls must be cleaned regularly
and kept separately from personal clothing.
DWhere 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.
DObtain First Aid treatment immediately for open cuts and wounds.
DWash 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.
DDo not use petrol, kerosine, diesel fuel, gas oil, thinners or solvents for cleaning skin.
DUse barrier creams, applying them before each work period, to help the removal of oil from the skin
after work.
DIf skin disorders develop, obtain medical advice without delay.

GENERAL -Supplemental Restraint System (SRS)00-21
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
To improve safety, the SRS and seat belts with
pre-tensioner. These systems enhance collision
safety by restraining the front passengers in case
of an accident. The SRS works with the
pre-tensioner simultaneously when a collision is
detected.
The SRS consists of two air bag modules, SRS
air bag control unit (SRS-ECU), SRS warning lamp
and clock spring. The air bags are located in the
center of the steering wheel, above the glove box.
Each air bag has a folded air bag and an inflator
unit. The SRS-ECU under the floor console monitors
the system and has a safing G-sensor and an
analog G-sensor. The warning lamp on theinstrument 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 front seat belt retractor. Only authorized
service personnel should do work on or around
the SRS components and seat belt with
pre-tensioner. Those service personnel should read
this manual carefully before starting any such work.
Extreme care must be used when servicing the
SRS to avoid injury to the service personnel (by
inadvertent deployment of the air bags or
inadvertent operation of the seat belt with
pre-tensioner) or the driver (by rendering the SRS
or the seat belt with pre-tensioner inoperative).

6. Inspection of the SRS-ECU harness connector should be carried out by the following procedure.
Insert the special tool (probe, MB991222, in the harness set) into the connector from harness side
(rear side), and connect the tester to this probe. If any tool than specified is used, damage to the
harness and other components will result. Furthermore, measurement should not be carried out by
touching the probe directly against the terminals from the front of the connector. The terminals are
plated to increase their conductivity, so that if they are touched directly by the probe, the plating
may break, which will cause drops in reliability.

MPI -General Information13A-3
GENERAL INFORMATION
The Multipoint Fuel Injection System consists
of sensors which detect the engine conditions,
the engine-ECU which controls the system
based on signals from these sensors, and
actuators which operate under the control of
the engine-ECU. The engine-ECU carries outactivities such as fuel injection control, idle
speed control and ignition timing control. In
addition, the engine-ECU is equipped with
several diagnosis modes which simplify
troubleshooting when a problem develops.
FUEL INJECTION CONTROL
The injector drive times and injector timing are
controlled so that the optimum air/fuel mixture
is supplied to the engine to correspond to the
continually-changing engine operation condi-
tions.
A single injector is mounted at the intake port
of each cylinder. Fuel is sent under pressure
from the fuel tank by the fuel pump, with the
pressure being regulated by the fuel pressure
regulator. The fuel thus regulated is distributed
to each of the injectors.
Fuel injection is normally carried out once for
each cylinder for every two rotations of the
crankshaft. The firing order is 1-3-4-2. This iscalled sequential fuel injection. The
engine-ECU provides a richer air/fuel mixture
by carrying out “open-loop” control when the
engine is cold or operating under high load
conditions in order to maintain engine
performance. In addition, when the engine is
warm or operating under normal conditions,
the engine-ECU controls the air/fuel mixture
by using the oxygen sensor signal to carry out
“closed-loop” control in order to obtain the
theoretical air/fuel mixture ratio that provides
the maximum cleaning performance from the
three way catalyst.
IDLE AIR CONTROL
The idle speed is kept at the optimum speed
by controlling the amount of air that bypasses
the throttle valve in accordance with changes
in idling conditions and engine load during
idling. The engine-ECU drives the idle speed
control motor to keep the engine running at
the pre-set idle target speed in accordance
with the engine coolant temperature and airconditioner load. In addition, when the air
conditioner switch is turned off and on while
the engine is idling, the idle speed control motor
operates to adjust the throttle valve bypass
air amount in accordance with the engine load
conditions in order to avoid fluctuations in the
engine speed.
IGNITION TIMING CONTROL
The power transistor located in the ignition
primary circuit turns ON and OFF to control
the primary current flow to the ignition coil. This
controls the ignition timing in order to provide
the optimum ignition timing with respect to theengine operating conditions. The ignition timing
is determined by the engine-ECU from the
engine speed, intake air volume, engine coolant
temperature and barometric pressure.
SELF-DIAGNOSIS FUNCTION
DWhen an abnormality is detected in one
of the sensors or actuators related to
emission control, the engine warning lamp
(check engine lamp) illuminates as a
warning to the driver.
DWhen an abnormality is detected in one
of the sensors or actuators, a diagnosis
code corresponding to the abnormality is
output.DThe RAM data inside the engine-ECU that
is related to the sensors and actuators can
be read by means of the MUT-II. In addition,
the actuators can be force-driven under
certain circumstances.
