Trouble Diagnoses
SYMPTOM: Headlamp aiming does not operate.
POWER SUPPLY CIRCUIT CHECK
(For aiming switch)
IDisconnect headlamp aiming switch
connector.
ITurn lighting switch to 1st. position.
Check if voltage between headlamp aim-
ing switch connector terminalq
3and body
ground.
OK
ENG

CD AUTOCHANGER
Symptom Possible cause Repair order
No play of the CD after CD play
button is pushed.1. Radio
(The radio is not working.)
2. Harness connection
(Magazine does not eject.)
3. Discs
4. Magazine does not eject or a
disc remains in CD player.
5. Changer1. Remove the radio for repair.
2. Check harness connection.
3. Inspect disc.
(Refer to testing magazines and discs.)
4. Reset the changer.
(Disconnect harness connector at the changer and
reconnect after 30 sec.)
5. Remove the changer for repair.
CD skipping. 1. Rough road driving
2. Discs
3. Bracket
4. Changer1. System is not malfunctioning.
2. Inspect discs.
(Refer to testing magazines and discs.)
3. Check and repair bracket and installation of
changer.
4. Remove the changer for repair.
Error code [NO DISC] is shown on
the radio after CD play button is
pressed.1. Magazine setting
2. Magazine
3. Changer1. Confirm the magazine is pushed completely.
2. Inspect magazine.
(Refer to testing magazines and discs.)
3. Remove the changer for repair.
Testing magazines and discs
1. Confirm discs are installed correctly into the magazine (not upside down).
2. Visually inspect/compare the customer's discs with each other and other discs.
Identify any of the following conditions:
IDiscs with a large outside diameter. [Normal size is 120 mm (4.72 in).]
IDiscs with rough or lipped edges.
IDiscs with excessive thickness [Normal size is 1.2 mm (0.047 in).]
IDiscs with scratches, abrasions, or pits on the surface.
IDiscs with grease/oil, fingerprints, foreign material.
IDiscs are warped due to excessive heat exposure.
3. Slide/place the discs in and out of the various magazine positions.
Identify any discs and/or positions that require additional force for placement/ejection. If interference
(sticking, excessive tensions) is found, replace the magazine or the discs.
Note:
IDiscs which are marginally out of specification (ex. dirty, scratched and so on) may play correctly
on a home stereo.
However, when used in the automative environment skipping may occur due to the added vehicle
movement and/or vibration due to road conditions. Autochangers should not be replaced when
discs are at fault.
IUse a soft damp cloth to wipe the discs starting from the center outward in radial direction. Never
use chemical cleaning solutions to clean the discs.
