0A-14 GENERAL INFORMATION

NOTES FOR ELECTRONIC CONTROL SYSTEM INSPECTION AND SERVICE

Scan Tool (External Diagnosis Device)

Use the specified scan tool in order to carry out fast and
correct inspection of parts.
Make sure to refer to detailed description in the repair
manual because the type and connection of a scan tool
to be used differ according to vehicles and devices.

Circuit Tester

When using a circuit tester, observe the procedure indi-
cated in the repair manual. If the procedure is not ob-
served, other relevant parts may be damaged. If a
specific type of circuit tester is specified, do not use any
circuit tester of other type. If a circuit tester, which is not
of the specified type, is used, other relevant parts may
be damaged, and measurement may not be done cor-
rectly.

Caution:
If any circuit tester, which is not of the specified type, is
used, the SRS and other electronic control system may
malfunction.

Failure due to Static Electricity Discharge

When static electricity is discharged, relevant parts are
charged with high voltage, and may be damaged. Ob-
serve the following items and take a proper action.

• Repair staff may be charged with static electricity

through work place and clothes. Touch any normal
grounding before inspecting and replacing relevant
parts.

• Do not directly touch the connector pins of relevant

parts. Do not rub them with other parts or cover.

• Connect the replacement parts to the normal

grounding without unwrapping them. And then,
take them out without letting them come into con-
tact with the connector pins.

Additional Electric Equipment

If the vehicle is equipped with additional electric parts in-
cluding lights, audio and radio devices, the electronic
control system may be adversely affected by electric
noises including radio wave emitted by those devices,
depending on the installing condition. Turn off the addi-
tional electric parts beforehand, or carry out removal in-
spection and service.

Notes for Welding

Take the following actions before carrying out welding
operation to protect the relevant parts.

• Remove the battery cable.
• Remove harnesses from all the control units.
• Turn all the switches to “OFF”.
• Install the grounding of the welding machine in a

place as close to the welding point as possible.

Repetition of Trouble

If the same trouble is generated repeatedly or momen-
tarily, or the trouble does not repeat whereas the trouble
display is indicated, check whether the trouble repeats
by taking following actions.

• Shake by hand the relevant parts, including control

units, sensors, relays and harnesses.
The trouble may repeat in case of connection fail-
ure.

• Heat the relevant parts using a dryer, or cool these

parts using a refrigerant. The trouble may repeat if
it is caused by temperature change.

Caution:
Do not heat the parts excessively to the level that cannot
be touched.

• Sprinkle the vehicle with water. The trouble may re-

peat if it is caused by humidity change.

Caution:
Do not sprinkle water directly on the electric parts.

GENERAL INFORMATION 0A-15

RECOMMENDED LIQUID GASKET AND LOCTITE

Liquid Gasket

• It is very important that the liquid gasket listed

above or their exact equivalent be used on the ve-
hicle.

• LOCTITE 515, LOCTITE 518 and FMD127 harden

upon contact with a metal surface. Do not apply
LOCTITE 515, LOCTITE 518 or FMD127 between
two metal surfaces having a clearance of greater
than 0.25 mm (0.001 in). Poor adhesion will result.

• Use a proper amount of the liquid gasket. Observe

the precautions for each product.

Application Procedure

1. Completely remove lubricant and moisture from

the connecting surfaces. The surfaces must be
perfectly dry.

2. Apply specified bead width 2 — 3 mm (0.08 — 0.12

in) of liquid gasket to one of the connecting surfac-
es. And the bead should be continuous.

0A-16 GENERAL INFORMATION

Notice:
When the application procedures are specified in this
workshop manual, follow them.

Recommended Loctite (Thread Locking
Agent)

Application Steps

1. Completely wipe all lubricant and moisture from the

bolts and bolt holes, and the female thread con-
necting surfaces. The surfaces must be perfectly
dry.

2. Apply LOCTITE to the 1/3 tip of the bolt’s threaded

area.

3. Tighten the bolts to the specified torque.

Important:
After tightening, be sure to keep the bolts free from vi-
bration and torque for at least an hour until LOCTITE
hardens.
