Trouble Diagnoses
Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspec-
tion Table.
+Before starting, inspect the fusible link.
+Use fully charged battery.

Note:
+If the inspection result is OK even though the charging system is malfunctioning, check the B ter-
minal connection. (Check the tightening torque.)
+When ®eld circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary,
replace faulty parts with new ones.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate ``CHARGE'' warning lamp, if any of the following
symptoms occur while alternator is operating:
+Excessive voltage is produced.
+No voltage is produced.

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine com-
partment side without removing the headlamp body.
+Grasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Turn the bulb retaining ring counterclockwise until it is free from
the headlamp re¯ector, and then remove it.
3. Disconnect the harness connector from the back side of the
bulb.
4. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
5. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp re¯ector without bulb for a long period
of time. Dust, moisture, smoke, etc. entering headlamp body
may affect the performance of the headlamp. Remove head-
lamp bulb from the headlamp re¯ector just before a replace-
ment bulb is installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. Aimers should be
in good repair, calibrated and operated in accordance with respec-
tive operation manuals.
If any aimer is not available, aiming adjustment can be done as
follows:
For details, refer to the regulations in your own country.
a. Keep all tires in¯ated to correct pressures.
b. Place vehicle and tester on one and same ¯at surface.
c. See that there is no-load in vehicle (coolant, engine oil
®lled up to correct level and full fuel tank) other than the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ``0'' when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.

FUEL WARNING LAMP SENSOR CHECK
+It will take a short time for the bulb to light.
NOTE: Inspection for sub fuel warning lamp sensor is the
same as for fuel warning lamp sensor.
OIL PRESSURE SWITCH CHECK

Engine stopLess than 10 - 20
(0.10 - 0.20, 0.1 - 0.2,1-3)YES
Check the continuity between the terminals of oil pressure switch
and body ground.
DIODE CHECK
+Check continuity using an ohmmeter.
+Diode is functioning properly if test results are as shown in the
®gure at left.
NOTE: Speci®cation may vary depending on the type of tester.
Before performing this inspection, be sure to refer to
the instruction manual for the tester to be used.
+Diodes for warning lamps are built into the combination meter
printed circuit.

Filament Check
1. Attach probe circuit tester (in volt range) to middle portion of
each ®lament.
+When measuring voltage, wrap tin foil around the top of
the negative probe. Then press the foil against the wire
with your ®nger.
2. To locate burned out point, move probe to left and right along
®lament. Test needle will swing abruptly when probe passes the
point.
+If a ®lament is burned out, circuit tester registers 0 or 12
volts.

(Refer to testing magazines and discs.)
3. Remove the changer for repair.
Testing magazines and discs
1. Con®rm 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:
+Discs with a large outside diameter. [Normal size is 120 mm (4.72 in).]
+Discs with rough or lipped edges.
+Discs with excessive thickness [Normal size is 1.2 mm (0.047 in).]
+Discs with scratches, abrasions, or pits on the surface.
+Discs with grease/oil, ®ngerprints, foreign material.
+Discs 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:
+Discs which are marginally out of speci®cation (ex. dirty, scratched and so on) may play correctly
on a home stereo.
However, when used in the automotive 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.
+Use 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.
