± DIAGNOSTICSAUDIO SYSTEM
AVENSIS REPAIR MANUAL (RM1018E)
(b) Multipath
Interference caused by reflection of radio waves against
obstructions is called ºMultipathº. Multipath occurs when
radio signals emitted from the broadcast transmitter an-
tenna are reflected against tall buildings or mountains
and interferes with other signals which are to be received
directly.
(c) Fade Out
Because FM frequency is higher than that of AM, FM ra-
dio wave tends to be reflected against obstructions such
as tall buildings or mountains. For this reason, FM signals
often seems to gradually disappear or fade away as the
vehicle goes behind those obstructions. This phenome-
non is called ºfade outº.
4. NOISE PROBLEMS
(a) It is very important for noise troubleshooting to understand a customer's claim clearly. Use the following
table to diagnose the phenomenon.
Radio waveCondition in which noise occursProbable cause
Noise occurs at a specific place.Strong possibility of foreign noise.
AM
Noise occurs when listening to faint broadcasting.The same program may be broadcasted from some local sta-
tions. If the program is the same, one of those may be tuned
in.
Noise occurs only at night.Strong possibility of beat from a distant broadcasting.
FMNoise occurs at a specific place while driving.Strong possibility of multipath noise and fading noise caused
by changes of FM frequency.
HINT:
If the condition where the noise occurs does not meet any of the above, find out the cause based on ºRecep-
tion Problemsº. Refer to the description about Multipath and Fading mentioned previously.
5. COMPACT DISC PLAYER
(a) Compact Disc (hereafter called ºCDº) Players use a laser beam pick±up to read the digital signals re-
corded on the CD and reproduce analog signals of the music, etc. 4.7 in. (12 cm) and 3.2 in. (8 cm)
discs are available for the CD player.
HINT:
Never attempt to disassemble or apply oil to any part of the player unit. Do not insert any object into the maga-
zine except for a disc.
NOTICE:
CD players use an invisible laser beam which could cause hazardous radiation exposure. Be sure
to operate the player correctly as instructed.

6. MAINTENANCE
Tape Player / Head Cleaning:
(a) Raise the slot cover with your finger.
Using a pencil or similar object, push in the guide.
(b) Using a cleaning pen or cotton applicator soaked in clean-
er, clean the head surface, pinch rollers and capstans.
7. MAINTENANCE
CD Player / Disc Cleaning:
If the disc gets dirty, clean the disc by wiping the surface from
the center to outside in the radial directions with a soft cloth.
NOTICE:
Do not use a conventional record cleaner or anti±static pre-
servative.
8. COMMUNICATION SYSTEM
(a) Components in the audio system communicate each other though AVC±LAN. (Radio receiver func-
tion)
(b) The master component of AVC±LAN is the radio receiver assy with a resistance (60 ± 80
), which
is necessary for communication.
(c) When short circuit or open circuit occurs in the AVC±LAN circuit, the audio system does not operate
normally due to the communication cutoff.
9. DIAGNOSIS FUNCTION
(a) The audio system has diagnosis function (The diagnosis result is displayed on the LCD of the radio
receiver assy). (Radio receiver function)
(b) The component code (physical address), or three±digit number (in hexadecimal) is set for each com-
ponent comprising AVC±LAN.
(c) The logical address, or two±digit number (in hexadecimal) is set for each function and component unit
in each component.
