(b) Matters that require attention when checking:
Noise coming into the radio usually has no harm for
daily use as the noise protection is taken, and it is
very rate for an extremely loud noise to come in.
When extremely loud noise comes into the radio,
check if the grounding is normal where the antenna
is installed.
Check if all the regular noise prevention parts are
properly installed, and if there is any installation of
non-authorized parts and non-authorized wiring.
If you leave the radio under out of tune (not turning),
it is easy to diagnose the phenomenon as noise oc-
curs frequently.
(c) Antenna and noise:
Electronic signal received by the antenna will reach to the
radio transmitting through the core wire of the coaxial
cable. Any noise wave other than radio wave is mixed into
this core wire, that naturally causes noise in the radio and
poor sound quality. In order to prevent the noise from
coming into radio, the core wire inside the coaxial cable
is covered with a mesh wire called shield wire which trans-
mits the noise to the ground.
5. COMPACT DISC PLAYER
Compact Disc Players use a laser beam pick-up to read the dig-
ital signals recorded on the CD and reproduce analog signals
of the music, etc.
HINT:
Never attempt to disassemble or oil any part of the player unit.
Do not insert any object other than a disc into the magazine.
NOTICE:
CD players use an invisible laser beam which could cause
hazardous radiation exposure. Be sure to operate the play-
er correctly as instructed.
6. Tape player/head cleaning:
MAINTENANCE
(a) Raise the cassette door with your finger.
Next, using a pencil or similar object, push in the guide.
(b) Using a cleaning pen or cotton applicator soaked in clean-
er, clean the head surface, pinch rollers and capstans.

5. INSPECT DRIVE BELT
HINT:
A belt tensioner is used, so checking the belt tension is not nec-
essary.
(a) Visually check the drive belt for excessive wear, frayed
cords etc.
If necessary, replace the drive belt.
HINT:
Cracks on the rib side of a drive belt are considered ac-
ceptable. If the drive belt has chunks missing from the
ribs, it should be replaced.
The drive belt tension can be released by turning the belt
tensioner counterclockwise. The pulley bolt for the belt
tensioner has a left-hand thread.
(b) Check the belt tensioner operation.
Check that the belt tensioner moves downward
when the drive belt is pressed down at the points in-
dicated in the illustration with approx. 98 N (10 kgf,
22.0 lbf) of force.
Check the alignment of the belt tensioner pulley to
make sure the drive belt has not slipped off the
pulley.
If necessary, replace the belt tensioner.
Check that the arrow mark on the belt tensioner falls
within area A of the scale.
If it is outside area A, replace the drive belt.
HINT:
When a new belt is installed, it should lie within area B. If
not, the drive belt is not correct.
After installing a belt, check that it fits properly in the
ribbed grooves.
Check by hand to confirm that the belt has not slipped out
of the groove on the bottom of the pulley.
6. REMOVE ENGINE UNDER COVER NO.1
7. VISUALLY CHECK GENERATOR WIRING AND LIS-
TEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.

ABS Warning Light Circuit
CIRCUIT DESCRIPTION
If the ECU detects trouble, it lights the ABS warning light while at the same time prohibiting ABS control. At
this time, the ECU records a DTC in memory.
Connect terminals Tc and E
1 of the DLC1 or Tc and CG of DLC3 to make the ABS warning light blink and
output the DTC.
