GENERAL -How to Use Troubleshooting/Inspection Service Points00-13
INSPECTION SERVICE POINTS FOR A BLOWN
FUSE
Remove the blown fuse and measure the resistance between
the load side of the blown fuse and the earth. Set the switches
of all circuits which are connected to this fuse to a condition
of continuity. If the resistance is almost 0Ωat this time,
there is a short somewhere between these switches and the
load. If the resistance is not 0Ω, 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.
DHarness being clamped by the vehicle body
DDamage to the outer casing of the harness due to wear
or heat
DWater getting into the connector or circuitry
DHuman error (mistakenly shorting a circuit, etc.)
POINTS TO NOTE FOR INTERMITTENT
MALFUNCTIONS
Intermittent malfunctions often occur under certain conditions,
and if these conditions can be ascertained, determining the
cause becomes simple. In order to ascertain the conditions
under which an intermittent malfunction occurs, first ask the
customer for details about the driving conditions, weather
conditions, frequency of occurrence and trouble symptoms,
and then try to recreate the trouble symptoms. Next, ascertain
whether the reason why the trouble symptom occurred under
these conditions 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 generates diagnosis codes or trouble
symptoms.)
DGently shake the connector up, down and to the left and
right.
DGently shake the wiring harness up, down and to the
left and right. Check the branch point of wiring harness
connector closely.
DGently rock each sensor and relay, etc. by hand.
DGently shake the wiring harness at suspensions and other
moving parts.
NOTE
If determining the cause is difficult, the flight recorder function
of the MUT-IIcan also be used.

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).

GENERAL -Supplemental Restraint System (SRS)00-22
SRS SERVICE PRECAUTIONS
1. In order to avoid injury to yourself or others
from accidental deployment of the air bag and
accidental operation of the seat belt with
pre-tensioner during servicing, read and
carefully follow all the precautions and
procedures described in this manual.
2. Do not use any electrical test equipment on
or near SRS components, except those
specified on P.52B-6.
3. Never Attempt to Repair the Following
Components:
DSRS air bag control unit (SRS-ECU)
DClock spring
DDriver’s and front passenger’s air bag
modules
DSeat belt with pre-tensionerNOTE
If any of these components are diagnosed as
faulty, they should only be replaced, in
accordance with the INDIVIDUAL COM-
PONENTS SERVICE procedures in this
manual. (Refer to P.52B-49.)
4. After disconnecting the negative (–) battery cable,
wait 60 seconds at least before any service and
insulate the disconnected cable with tape. The SRS
retain enough voltage to deploy the air bags for a
short time even after the disconnection of the battery.
So, serious injury may result by accidental air bag
deployment if a work is done on the SRS just after
the disconnection of the battery.
5. Do not attempt to repair the wiring harness connectors
of the SRS. If the connector(s) are diagnosed as defective,
replace the wiring harness(es). If the harness(es) are
diagnosed as faulty, replace or repair the wiring
harness(es) according to the table that follows.
