CHASSIS ELECTRICAL ± Radio and Tape Player54-65
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.>

CHASSIS ELECTRICAL ± Radio and Tape Player54-66
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.
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
characteristics of FM waves of noise ordistortion generated by typical noise
interference (first fading and multipath). (Refer
to A-2) areas such as mountainous regions, but this
is not due to a problem with the radio.>

Caution
Do not heat R-134a above 40
C
In most instances, moderate heat is required to
bring the pressure of the refrigerant in its container
above the pressure of the system when charging
or adding refrigerant.
A bucket or large pan of hot water not over 40
C
is all the heat required for this purpose. Do not
heat the refrigerant container with a blow torch
or any other means that would raise temperature
and pressure above this temperature. Do not weld
or steam clean on or near the system components
or refrigerant lines.
Caution
Keep R-134a containers upright when charging
the system.When metering R-134a into the refrigeration system
keep the supply tank or cans in an upright position.
If the refrigerant container is on its side or upside
down, liquid refrigerant will enter the system and
damage the compressor.
Caution
1. The leak detector for R-134a should be used
to check for refrigerant gas leaks.
2. Do not allow liquid refrigerant to touch bright
metal.
Refrigerant will tarnish bright metal and chrome
surfaces, and in combination with moisture can
severely corrode all metal surfaces.

STANDARD FOW 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 heard 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 Sound of the motor inside the ABS hydraulic unit operation.
(whine)
Sound is the generated along with vibration of the brak
pedal. (Scraping).
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 such as snow-covered roads and 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 suc
roads by lowering the vehicle speed and not being too
overconfident.
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 FUNCTION 35201120106
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.)
ERASING DIAGNOSIS CODES

DIAGNOSIS FUNCTION35201120351
DIAGNOSIS CODES CHECK
Read a diagnosis code by the MUT-II or ABS warning
lamp. (Refer to GROUP 00 - How to Use Trouble-
shooting/Inspection Service Points.)
ERASING DIAGNOSIS CODES
With the MUT-II
Refer to GROUP 00 – How to Use
Troubleshooting/Inspection Service Points

When diagnostic trouble codes (Nos. 21 to 24) (for vehicle wheel speed sensor system failures) occur,
normal MUT-II operation may not erase those codes. In that case, erase the diagnostic trouble codes
using the following procedures.
1.
Perform erasing of the diagnostic trouble codes by special operation of the brake pedal. (See erasing
procedure for the diagnostic trouble codes without use of the MUT-II.)
2.
Turn the ignition switch OFF.
3.
Perform erasing of the diagnostic trouble codes by use of the MUT-II.
