R.H. and L.H. doors can be locked and unlocked
by the transmitter but the dome light and footlight do not blink or come on. (Interlocked
lighting of the dome light and foot light by means
of the dome light switch or door opening and
closing is normal).

does not operate.1) Check the cryptographic code registering
method. (Refer to GROUP
42-Keyless
Entry System.)
2)Check the keyless entry control unit terminalvoltage. (Refer to GROUP

the ground wire for connection.
l Only R.H. or L.H. door can be locked or
unlocked.
1)Check the door lock power relay 1 (for front
passenger’s door) or door lock power relay2 (for driver’s door). (Refer to GROUP

A-2Noise appears at certain places when traveling (FM).Do the following measures eliminate the noise?
YeslChange to a different station with a strong signal to boost resistance to interference.l Suppress high tones to reduce noise.+3cll Extend antenna completely. (Whip antenna)
No
tIf there is more noise than other radios, find out the noise conditions and the name and frequency
of the receiving stations from the user, and consult with the service center.
NOTE
About FM waves:
FM waves have the same properties as light, and
can be deflected and blocked. Wave reception isnot possible in the shadow of obstructions such
as buildings or mountains.
1.The signal becomes weak as the distance from
the station’s transmission antenna increases.
Although this may vary according to the signal
strength of the transmitting station and interven-ing geographical formations or buildings, the
area of good reception is approx.
20-25 km
(12-l 6 miles) for stereo reception, and 30-40km (19-25 miles) for monaural reception.
2. The signal becomes weak. when an area of
shadow from the transmitting antenna (places
where there are obstructions such as mountains
3.
4.
or buildings between the antenna and.the car),
and noise will appear. <This is called first fading,
and gives a steady buzzing noise.>
If a direct signal hits the antenna at the same
time as a signal reflected by obstructions such
as mountains or buildings, interference of the
two signals will generate noise. During traveling,
noise will appear each time the vehicle’s anten-
na passes through this kind of obstructed area.The strength and interval of the noise varies
according to the signal strength and the condi-tions of deflection.
<This is called multipath
noise, and is a repetitious buzzing.>Since FM stereo transmission and reception
has a weaker field than monaural, it is often
accompanied by a hissing noise.FM Broadcast Good Reception Areas
