± 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.

ADJUSTMENT
1. HEADLIGHT AIM ONLY
HINT:
Perform aiming adjustment with Low±beam.
Since the Low±beam light and the High±beam light is a
unit, if aiming on either side is connect, the other side
should also be connect.
However, check both beams just to make sure.
(a) Prepare vehicle in the following conditions.
Check that any damage or deformation does not exist on
the body around the headlights.
Fuel tank is full.
The tire inflation pressure is at the specified level.
Vehicle is parked at a level surface.
A person having an average weight sits in the driver's
seat.
Vehicle is bounced up and down to stabilize the suspen-
sion to the normal position.
(b) Prepare a thick white paper (Draw base lines).
HINT:
Stand the paper perpendicular as against a wall.
The base lines differ for ºLow±beam inspectionº and
ºHigh±beam inspectionº.
(1) V line (Vehicle Center position)
Draw a vertical line down the center of the paper in
order to align it with the center of the vehicle.
(2) H line (Headlight height)
Draw horizontal line across the paper at the same
height from the ground as the center mark for the
Low±beam lights.
(3) V LH line, V RH line (Center mark position of right
and left headlights)
Draw vertical lines, for left & right, at the same posi-
tion as the center mark for the Low±beam lights.
HINT:
Follow the same procedures when adjusting the High±beam
lights.

(c) Check the headlight aiming.
(1) Align the paper with the center of the vehicle.
Make a distance of 3 m ( 9.84 ft) between the head-
lights and the paper, and put the paper against a
wall with the H line being at the same height as the
center mark.
Align the center of the vehicle with the V line on the
paper, and ensure that the paper is at a 90 angle
in accordance to the V line.
(2) Start the engine.
(3) Turn on the headlights and check that the aim is with
in the specified valves shown in the illustration.
NOTICE:
When covering the headlights, finish it within 3 mi-
nuites.
The headlight lens is made of synthetic resin, so it is
easily.
HINT:
When checking the aiming of the High±beam, shut off the Low±
beam or disconnect the Low±beam headlight connector.
(d) Adjust the aim in the vertical direction:
Using a screwdriver, adjust the headlight aim within the
specified range by turning the aiming screw A.
NOTICE:
Adjust the headlight aim by turning the screw in the
tightening direction.
When the screw is tightened excessively, loosen it
once and re±tighten it to adjust the headlight aim.
HINT:
The optical axis aim moves downward when turning the screw-
driver clockwise, and it moves upward when turning the screw-
driver counterclockwise.
(e) Adjust the aim in the horizontal direction:
Using a screwdriver, adjust the headlight aim within the
specified range by turning the aiming screw B.
NOTICE:
Adjust the headlight aim by turning the screw in the
tightening direction.
When the screw is tightened excessively, loosen it
once and re±tighten it to adjust the headlight aim.
