Noise InspectionAKS005TC
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.
TYPE OF NOISE AND POSSIBLE CAUSE
Occurrence condition Possible cause
Occurs only when
engine is ON. A continuous growling noise occurs. The speed of the
noise varies with changes in the engine speed.

Ignition condenser
A whistling noise occurs while the engine speed is
high. A booming noise occurs while the engine is run-
ning and the lighting switch is ON.

Alternator
The occurrence of the noise is linked with the operation of the fuel pump.

Fuel pump condenser
Noise only occurs
when various elec-
trical components
are operating. A cracking or snapping sound occurs with the opera-
tion of various switches.

Relay malfunction, radio malfunction
The noise occurs when various motors are operating.

Motor case ground

Motor
The noise occurs constantly, not just under certain conditions.

Rear window defogger coil malfunction

Open circuit in printed heater

Poor ground of antenna amplifier or antenna feeder
line

Mirror type film is attached on the rear window glass

After-market TV antenna and/or electrical accessories
such as radio are attached on the rear window glass.
A cracking or snapping sound occurs while the vehicle is being driven,
especially when it is vibrating excessively.

Poor ground of audio parts

Poor ground due to incorrect installation of parts

Poor wiring connections or a short circuit

Trouble Diagnosis" .
2. CHECK HARNESS
1. Turn the ignition switch OFF.
2. Disconnect audio unit connector and unified meter and A/C amp. connector.
3. Check continuity between audio unit harness connector M60 ter- minal 22 (W/L) and unified meter and A/C amp. harness connec-
tor M56 terminal 34 (W/L).
4. Check continuity between audio unit harness connector M60 ter- minal 22 (W/L) and ground.

3. CHECK VEHICLE SPEED SIGNAL
1. Connect unified meter and A/C amp. connector.
2. Start engine and drive vehicle at more than 40 km/h (25MPH).
3. Check the signal between audio unit harness connector M60 terminal 22 (W/L) and ground with CON- SULT-ll or oscilloscope.

OK >> INSPECTION END (System is OK.)
NG >> Replace unified meter and A/C amp.
Locking CD Auto-Changer MechanismAKS007GD
CAUTION:

Prior to removing a malfunctioning CD auto-changer unit that will be shipped for repair, the
changer mechanism MUST BE LOCKED to prevent the mechanism from being damaged during
shipping.

If a CD is jammed or unable to be removed from the unit, do NOT lock the changer mechanism. If
the unit is to be shipped for repair, carefully package the unit to prevent vibration and shock.
DAMPER LOCK PROCEDURE
1. Eject and remove any CDs from the audio unit.
2. Turn ignition switch OFF. Wait until audio unit display is off and mechanism stops moving (mechanism sound stops).
3. Press any one of the disc selection buttons once. When a display shows on the audio unit, press the same disc selection button again within 5 seconds.

The changer mechanism will lock itself within 10 seconds.
4. After mechanism stops moving (mechanism sound stops), open the driver and passenger window, and then disconnect negative battery cable.
NOTE:
After installing a new or remanufactured audio unit, switching the audio unit ON will automatically unlock the
mechanism. A special unlocking procedure is not required.
