HOW TO USE THE INSPECTION PROCEDURES
The causes of a high frequency of problems occurring in electronic circuitry are generally the connectors,
components, the ECU and the harnesses between connectors, in that order. These inspection procedures
follow this order, and they first try to discover a problem with a connector or a defective component.

3. Detailed inspection procedures (methods)
such as component inspection and circuit
inspection are listed on a separate page, and
are given here for reference.
6. Confirm that there are trouble symptoms. If trouble symptoms have
disappeared, the connector may have been inserted incorrectly and the
trouble symptom may have disappeared during inspection.
If it seems that trouble symptoms still remain, proceed to the next page of
instructions.
7. If trouble symptoms still remain up to this stage, there is a possibility that there is an
open or short circuit in the harness between the connectors, so check the harness.
Alternatively, the cause may be a defective ECU, so try replacing the ECU and check
if the trouble symptom disappears.
HARNESS INSPECTION
Check for an open or short circuit in the harness between the terminals which were defective according
to the connector measurements. Carry out this inspection while referring to the electrical wiring manual.
Here, “Check harness between power supply and terminal xx” also includes checking for blown fuses.
For inspection service points when there is a blown fuse, refer to “Inspection Service Points for a Blown
Fuse.”
MEASURES TO TAKE AFTER REPLACING THE ECU
If the trouble symptoms have not disappeared even after replacing the ECU, repeat the inspection procedure
from the beginning.

IF INSPECTING WITH THE CONNECTOR CONNECTED
(WITH CIRCUIT IN A CONDITION OF CONTINUITY)
Waterproof Connectors
Be sure to use the special tool (harness connector). Never
insert a test bar from the harness side, because to do so
will reduce the waterproof performance and result in corrosion.
Ordinary (non-waterproof) Connectors
Check by inserting the test bar from the harness side. Note
that if the connector (control unit, etc.) is too small to permit
insertion of t h e test bar, it should not be forced; use a special
tool (the extra-thin probe in the harness set for checking
for this purpose.
IF INSPECTING WITH THE CONNECTOR DISCONNECTED
<When Inspecting a Female Pin>
Use the special tool (inspection harness for connector pin
contact pressure in the harness set for inspection).
The inspection harness for connector pin contact pressure
should be used. the test bar should never be forcibly inserted,
as it may cause a defective contact.
<When Inspecting a Male Pin>
Touch the pin directly with the test bar.
Caution
At this time, be careful not to short the connector pins
with the test bars. To do so may damage the circuits
inside the ECU.

CONNECTOR PIN INSPECTION
If the connector pin stopper is damaged, the terminal
connections (male and female pins) will not be perfect even
if the connector body is connected, and the pins may pull
out of the reverse side of th e connector. Therefore, gently
pull the harnesses one by one to make sure that no pins
pull out of th e connector.

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 a n d 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 t he 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 an d to the left and
right.
DGently shake the wiring harness up, down and to the
left and right.
DGently rock each sensor and relay, etc. by hand.
DGently shake the wiring harness at suspensions an d other
moving parts.
NOTE
If determining the cause is difficult, the flight recorder function
of the MUT-II can also be used.

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.
GENERAL -
Precautions Before Service
Other precautions:
DAvoidprolongedandrepeated contactwithoils,
particularly used engine oils.
DWear protective clothing, including impervious gloves
where practicable.
DAvoid contaminating clothes, particularly underpants, with
oil.
DDo n ot put oily rags in pockets, the use of overalls without
pockets will avoid this.
DDo not wear heavily soiled clothing a nd oil-impregnated
foot-wear. Overalls must be cleaned regularly an d 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 th e 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.

Supplemental Restraint System (SRS)
and Seat Belt with Pre-tensioner
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AND SEAT BELT
WITH PRE-TENSIONER
00100590073
To improve safety, the SRS and seat belts with
pre-tensioner are available as optional parts. 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 four air bag modules, SRS
air bag control unit (SRS-ECU), side impact sensor,
SRS warning lamp and clock spring. The air bags
are located in the centre of the steering wheel,
above the glove box, and built into the front seat
back assemblies. 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 side impact
sensor inside the center pillar monitors any shocks
coming from the side of the vehicle. The warning
lamp on the instrument panelindicates the
SRS warning lamp
operational status of the SRS. The clock spring
is installed in the steering column.
The SRS side air bag deploys if an impact received
at the side of the vehicle is stronger than a certain
set value, in order to protect the upper bodies of
front seat passengers in the event of a collision.
The seat belt pre-tensioner is built into the front
seatbeltretractor.Onlyauthorizedservice
personnel should do work on or around the SRS
components a nd 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).

Supplemental Restraint System (SRS)
and Seat Belt with Pre-tensioner
SEAT BELT WITH PRE-TENSIONER
The seat belts with pre-tensioners are installed on
both center pillars.
The pre-tensioner, which is controlled by the SRSECU, works simultaneously with the SRS air bag
in a head-on collision. When triggered, the SRSECU sends a squib igniting signal to the gas generator. Generated gas moves the rotor to take up seat
00-25
belt slack. This prevents a passenger from moving
forwards excessively. After this, the ELR works to
inhibit the seat belt.
Caution
Never disassemble or give an impact to the
seat belt with pre-tensioner.

4.Afterdisconnectingthe battery cable, wait60seconds
or more before proceeding with the following work.
The SRS system is designed to retain enough voltage
to deploy the air bag for a short time even after the
battery has been disconnected, so serious injury may
result from unintended air bag deployment if work is
done on the SRS system immediately after the battery
cables are disconnected.
5.Do not attempt to repair the wiring harness connectors
of the SRS. If any of the connectors are diagnosed as
faulty, replace the wiring harness. If the wires are
diagnosed as faulty, replace or repair the wiring harness
according to the following table.

6.Inspection of the SRS-ECU harness connector <vehicles with SRS side air bag> should be carried
out by the following procedure.
Insert the special tool (narrow probe in the harness set) into connector from harness side (rear side),
and connect the tester to this probe. If any to other than the special tool is used, it may cause
damage to the harness and other components. 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.
