SYSTEM DESCRIPTION
1. DISC PLAYER OUTLINE
(a) A CD player uses a laser pickup to read digital
signals recorded on CDs. By converting the digital
signals to analog, music and other content can be
played.
CAUTION:
Do not look directly at the laser pickup because
the CD player uses an invisible laser beam. Be
sure to operate the player only as instructed.
NOTICE:
• Do not disassemble any part of the CD player.
• Do not apply oil to the CD player.
• Do not insert anything but a CD into the CD
player.
(b) Usable discs
(1) The CD player can only play audio CDs, CD-Rs
(CD-Recordable), and CD-RWs (CD-
ReWritable) that have any of the following
marks:
(c) Precautions for use of discs
NOTICE:
• Copy-protected CDs cannot be played.
• CD-Rs and CD-RWs may not be played
depending on the recording conditions or
characteristics of the discs, or due to
damage, dirt, or deterioration caused by
leaving the discs in the cabin for a long time.
• Unfinalized CD-Rs and CD-RWs cannot be
played.
• Keep the discs away from dirt. Be careful not
to damage the discs or leave your
fingerprints on them.
• Hold discs by the outer edge and center hole
with the label side up.
• Leaving the disc exposed halfway out of the
slot for a long time after pressing the disc
eject button may cause deformation of the
disc, making the disc unusable.
• If discs have adhesive tape, stickers, CDR
labels, or any traces of such labels attached,
the discs may not be ejected or player
malfunctions may result.

(b) Images are difficult to discern even in normal
conditions if:
(1) Camera screen is frosted over (the image
immediately after turning the ignition switch to
the on position may be blurred or darker than
normal).
(2) A strong beam of light, such as a sunbeam or
headlight, hits the camera.
(3) It is too dark around the camera (at night, etc.).
(4) The ambient temperature around the camera is
either too high or too low.
HINT:
When a strong light, such as a sunbeam
reflected off the vehicle's body, hits the camera,
the image may be blurred. This is called the
"SMEAR" phenomenon, peculiar to the CCD
camera.

(b) Check that the belt fits properly in the ribbed
grooves.
HINT:
Check with your hand to confirm that the belt has
not slipped out of the groove on the bottom of the
pulley.
If it has slipped out, replace the V-ribbed belt. Install
a new V-ribbed belt correctly.
7. INSPECT GENERATOR WIRING
(a) Visually check the generator wiring.
(1) Check that the wiring is in good condition.
8. CHECK FOR ABNORMAL NOISES
(a) Listen for abnormal noises from the generator.
(1) Check that no abnormal noises are heard from
the generator while the engine is running.
9. CHECK CHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch to the ON position. Check
that the charge warning light comes on.
(b) Start the engine and check that the light goes off.
If the light does not operate as specified,
troubleshoot the charge warning light circuit.
10. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) Connect a voltmeter and ammeter to the charging
circuit as follows.

generator, then connect it to the negative (-)
lead of an ammeter.
(2) Connect the positive (+) lead of the ammeter to
terminal B of the generator.
(3) Connect the positive (+) lead of a voltmeter to
positive (+) terminal of the battery.
(4) Ground the negative (-) lead of the voltmeter.
(b) Check the charging circuit.
(1) Keep the engine speed at 2000 rpm and check
the reading on the ammeter and voltmeter.
Standard amperage:
10 A or less
Standard voltage:
13.2 to 14.8 V
If the result is not as specified, replace the
generator.
HINT:
If the battery is not fully charged, the ammeter
reading will sometimes be more than the
standard amperage.
11. INSPECT CHARGING CIRCUIT WITH LOAD
(a) Keep the engine speed at 2000 rpm, turn on the
high beam headlights, and turn the heater blower
switch to the "HI" position.
