9. Door Lock Signal:
INSPECT DOOR LOCK CONTROL RELAY
HINT:
When the relay circuit is as specified, inspect the door lock sig-
nal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 1 and the negative (−) lead to terminal 6.
(c) Set the door lock control switch to UNLOCK, check that
the voltage rises from 0 V to battery positive voltage for
approximately 0.2 seconds.

If operation is not as specified, replace the relay.
10. Key−off Power Window Signal:
INSPECT DOOR LOCK CONTROL RELAY

AUDIO SYSTEM
DESCRIPTION
1. RADIO WAVE BAND
2. SERVICE AREA
There are great differences in the size of the service area for AM
and FM monaural. Sometimes FM stereo broadcasts cannot be
received even though AM comes in very clearly at the same
location.
Not only does FM stereo have the smallest service area, but it
also picks up static and other types of interference (”noise”)
easily if the vehicle is moving in a fringe area.
3. RECEPTION PROBLEMS
Besides the problem by static, there are also the problems
called ”fading”, ”multipath” and ”fade out”. These problems are
caused not by electrical noise but by the nature of the radio
waves propagations.

Fading
Besides electrical interference, AM broadcasts are
also susceptible to other types of interference, es-
pecially at night. This is because AM radio waves
bounce off the ionosphere at night.
These radio waves then interfere with the signals
from the same transmitter that reach the vehicle’s
antenna directly. This type of interference is called
”fading”, because the reflected indirect signal
(which is off−phase in relation to the direct wave)
sporadically strengthen or weaken the resultant sig-
nal at reception point.
Multipath
One type of interference caused by bouncing of ra-
dio waves off of obstructions is called ”multipath”.
Multipath occurs when a signal from the broadcast
transmitter antenna bounces off buildings, moun-
tains and interference with the signal that is re-
ceived directly.
Fade Out
Because FM radio waves are of higher frequencies
than those of AM, they bounce off buildings, moun-
tains, and other obstructions. For this reason, FM
signals often seem to gradually disappear or fade
away as the vehicle goes behind a building or other
obstruction. This is called ”fade out”.
4. Tape player / Tape head cleaning:
MAINTENANCE OF TAPE PLAYER
Using a moist−type cleaning tape, clean the head surface,
pinch rollers and capstans (Never use ”abrasive” type cas-
sette−shaped cleaner.).

5. ANTI−THEFT SYSTEM
HINT:
The words ”ANTI−THEFT SYSTEM” are displayed on the cas-
sette tape slot cover.
For operation instructions for the anti−theft system, please con-
sult the audio system section in the Owner’s Manual (hereafter
called O/M).
(a) Setting system
The system is in operation once the customer has pushed
the required buttons and entered the customer−selected
3−digit ID number.
(Refer to the O/M section, ”Setting the anti−theft system”)
HINT:
When the audio system is shipped the ID number has not
been input, so the anti−theft system is not in operation.
If the ID number has not been input, the audio system re-
mains the same as a normal audio system.
(b) Anti−theft system operation
If the normal electrical power source (connector or battery
terminal) is cut off, the audio system becomes inoperable,
even if the power supply resumes.
(c) Canceling system
The ID number chosen by the customer is input to cancel
the anti−theft system.
(Refer to the O/M section, ”If the system is activated”)
HINT: To change or cancel the ID number, please refer to
the O/M section ”Canceling the system”.
