HANDLING OF AUTO WINDOW SEALER
Keep the sealant in a cool place, not exposed to the direct
rays of the sun. Do not place any heavy article on the sealant
nor press it, otherwise it will become deformed. Avoid storing
the sealant for more than 6 months, because it will lose its
sealing effect.
BODY PINCH-WELD FLANGE SERVICING.
Before servicing the body pinch-weld flange, remove old
adhesive completely. If the flange requires painting, bake
it after painting is completed.
WORKING PROCESS
Window glass installation procedure
Body side
Cleaning of adhesion surface
Cut off the residual adhesive until the
thickness is less than 2 mm. Clean the
adhesion surface with isopropyl alcohol,
and let dry for 3 minutes or more.
Attaching of spacer and dual lock
fastener
Attach the spacer and dual lock fastener
to set the positions for the glass to be
installed.
Application of primer
Apply to the adhesion surface of the
body and let dry for 3 minutes or more.
Window glass side
Reusing the glassReplacing the glass
Cleaning of adhesion surface
Competely cut off all of the residual
adhesive. Clean the adhesion surface
with isopropyl alcohol, and let dry for
3 minutes or more.Cleaning of adhesion surface
Clean off any dirt adhering to the adhe-
sion surface with isopropyl alcohol, and
let dry for 3 minutes or more.
Gluing window spacer and dual lock fastener
Glue the window spacer and dual lock fastener to the glass, following the standard position
all the way around the inside edge of the glass.
Application of primer
Apply sufficient primer evenly to the adhesion surface so that there is no patchiness. After
application, let dry for 3 to 30 minutes.
Application of adhesive
Within 30 minutes after applying the primer, apply the adhesive evenly all the way around
the inside edge of the glass.
Installing the glass
After applying the adhesive, lightly press the glass evenly so that it adheres
completely.
Cleaning
After removing any adhesive that is sticking out or adhering to the body or
glass with a spatula, ect., clean off with isopropyl alcohol.

A-4 Broadcasts can be heard but both AM and FM have a lot of noise.
(1)(2)
Noise occurs when the engine is stopped.
Ye s
Do the following measures eliminate the noise?

Tune to a station with a strong signal.

Extend the antenna completely.

Adjust the sound quality to suppress high tones.Ye s
OK
No
Is the radio body earth mounted securely?NoSecurely tighten the nuts for the body
earth.
Ye s
Is the antenna plug properly connected to the radio?NoCorrectly attach the antenna plug.
Ye s
Is the antenna itself in good condition or is it properly
mounted?NoClean the antenna plug and earth wire
mounting area. Mount the antenna se-
curely.
Ye s
If there is more noise than other radios, consult a service
centre.
Is the noise eliminated?
NoYe s
OK
Noise occurs when the engine in running.
Inspect the vehicle's noise suppressor. (Refer to A-6.)
NOTE
About noise encountered during FM reception only.
Due to differences in FM and AM systems, FM
is not as susceptible as AM to interference from
engines, power lines, lightning, etc. On the other
hand, there are cases due to the characteristicsof FM waves of noise or distortion generated by
typical noise interference (first fading and
multipath). (Refer to A-2.)
as mountainous regions, but this is not due to a
problem with the radio.>

A-5 There is more noise either on AM or on FM.
1. There is much noise only on AM.
Due to differences in AM and FM systems,
AM is more susceptible to noise interference.
Were conditions such as the following present when noise was
received?

Lightning was flashing. A motorcycle was passing.

A vehicle passed close by, but it appeared to be a vehicle
generating a particularly large amount of noise radiation.

Passed beneath a power line. Passed under a bridge.

Passed beneath a telephone line.

Passed close by a signal generator.

Passed close by some other source of electrical noise.
Ye s
No
Continue to check for static; when static is detected, check for
the conditions listed above.Ye sNoise prevention on the radio side is difficult. If the problem is
particularly worse than other radios, consult a service centre.
No
If the problem is particularly worse than other radios, consult a
service centre.
2. There is much noise only on FM.

from engines, power lines, lightning, etc. On
the other hand, there are cases due to the
characteristics of FM waves of noise ordistortion generated by typical noise

A-8 Noise sometimes appears on FM during travelling.
Does the problem clear up when retuned?Ye sOK
No
Does the problem appear only in certain locations and only with
certain stations?Ye sDue to electrical field conditions. (Multipath noise*, fading noise*).
Are connectors properly connected?NoCheck connector connections.
Ye s
Does noise appear when the radio switch is turned on while the
vehicle is stopped and the radio is struck while tuned away from
a station?NoStatic electricity noise:
Body static electric from the shock absorber rubber bushings used
to prevent vibration, tyres, etc. occurs because of separation from
the earth, causing a buzzing noise. Since no measures can be
taken on the radio side, other steps should be taken to discharge
the static electricity of the vehicle body.
Ye s
Is the radio body correctly earthed? (Is the mounting screw tightened
securely?)NoTighten the screw securely.
Ye s
Is the antenna correctly earthed? (If noise appears when the antenna
is moved, this means the earth is not securely connected.)NoIf rust is present at the antenna earth screw, clean and tighten
the earth securely.
Ye s
Repair or replace radio.
No
* About multipath noise and fading noise
Because the frequency of FM waves is
extremely high, it is highly susceptible to effects
from geological formations and buildings.
These effects disrupt the broadcast signal and
obstruct reception in several ways.

Multipath noise
This describes the echo that occurs when
the broadcast signal is reflected by a largeobstruction and enters the receiver with
a slight time delay relative to the direct
signal (repetitious buzzing).

Fading noise
This is a buzzing noise that occurs when
the broadcast beam is disrupted by
obstructing objects and the signal strength
fluctuates intricately within a narrow range.

STANDARD FLOW OF DIAGNOSTIC TROUBLESHOOTING
Refer to GROUP 00 – How to Use Troubleshooting/Inspection Service Points
NOTES WITH REGARD TO DIAGNOSIS
The Phenomena listed in the following table are not abnormal.
Phenomenon Explanation of phenomenon
System check sound When starting the engine, a thudding sound can sometimes be hear
coming from inside the engine compartment, but this is because the
system operation check is being performed, and is not an abnormality.
ABS operation sound 1.
Sound of the motor inside the ABS hydraulic unit operation (whine).
2.
Sound is generated along with vibration of the brake pedal
(scraping)
3.
When ABS operates, sound is generated from the vehicle chassis
due to repeated brake application and release.
(Thump: suspension: squeak: tyres)
ABS operation (Long braking
distance)For road surfaces suck as snow-covered roads an gravel roads, the
braking distance for vehicles with ABS can sometimes be longer than
that for other vehicles. Accordingly, advise the customer to drive safely
on suck roads by lowering the vehicle speed and not being to
overconfident.
Shock during system operation
checkShock may be felt when the brake pedal is depressed slightly at a low
driving speed. This occurs due to ABS operation check (initial check at
a vehicle speed of 8 km/h), and does not indicate any malfunction.
Diagnosis detection condition can vary depending on the diagnosis code.
Make sure that checking requirements listed in the “Comment” are satisfied when checking the trouble
symptom again.
DIAGNOSIS FUNCTION35201120108
DIAGNOSIS CODES CHECK
Read a diagnosis code by the MUT-II or ABS warning
lamp. (Refer to GROUP 00- How to Use
Troubleshooting/Inspection Service Points.)
