INSPECTION SERVICE POINTS FOR A BLOWN
FUSE

Remove the fuse and measure the resistance between the
load side of the 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 0 

Ω

 at this time, there

is a short somewhere between these switches and the load.
If the resistance is not 0 

Ω

, 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.

D

Harness being clamped by the vehicle body

D

Damage to the outer casing of the harness due to wear
or heat

D

Water getting into the connector or circuitry

D

Human 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.)

D

Gently shake the connector up, down and to the left and
right.

D

Gently shake the wiring harness up, down and to the
left and right.

D

Gently rock each sensor and relay, etc. by hand.

D

Gently shake the wiring harness at suspensions and other
moving parts.

NOTE
If determining the cause is difficult, the flight recorder function
of the MUT-

II

 can also be used.

Precautions Before Service

PRECAUTIONS BEFORE SERVICE

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

1.

Items to follow when servicing SRS
(1) Be sure to read GROUP 52B – Supplemental Restraint System (SRS).

For safe operations, please follow the directions and heed all warnings.

(2) Always use the designated special tools and test equipment.
(3) 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.

(4) Never attempt to disassemble or repair the SRS components. (SRS air bag control unit, air bag

module and clock spring.) If faulty, replace it.

(5) Warnings labels must be needed when servicing and handling SRS components. Warning labels

are located in the following locations.

D

Sun visor

D

Glove box

D

SRS air bag control unit

D

Steering wheel

D

Steering gear and linkage

D

Air bag module

D

Clock spring

(6) 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 upwards.

(7) Be sure to deploy the air bag before disposing of air bag module or disposing of a vehicle equipped

with an air bag. (Refer to GROUP 52B – Air Bag Module Disposal Procedures.)

(8) Whenever you finish servicing the SRS, check the SRS warning lamp operation to make sure

that the system functions properly.

2.

Observe the following when carrying out operations on place where SRS components are installed,
including operations not directly related to the SRS air bag.
(1) When removing or installing parts do not allow any impact or shock to the SRS components.
(2) SRS components should not be subjected to heat over 93

_

C, so remove the SRS components

before drying or baking the vehicle after painting.
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.

Precautions Before Service

00-16

SERVICING THE ELECTRICAL SYSTEM

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.

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.)

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.
