SERVICE
HEADLIGHT AIMING
PRE-AIMING INSTRUCTIONS
(Up to 1993 models)
1. Test dimmer switch operation.
2. Observe operation of high beam light mounted in instru-
ment cluster.3. Inspect for badly rusted or faulty headlight assemblies.
These conditions must be corrected before a satisfactory
adjustment can be made.4. Place vehicle on a level floor.
5. Bounce front suspension through three (3) oscillations
by applying body weight to hood or bumper.6. Inspect tire inflation.
7.Rock vehicle sideways to allow vehicle to assume its nor-
mal position.
8.If fuel tank is not full, place a weight in trunk of vehicle
9.
to simulate weight of a full tank [3 kg (6.5 Ibs.) per gallon].
There should be no other load in the vehicle other than
driver or substituted weight of approximately 70 kg (150
Ibs.) placed in driver’s position.
10. Thoroughly clean headlight lenses.
11. Adjust headlights following the instructions of the headlight
tester manufacturer.
(From 1994 models)1. Inspect for badly rusted or faulty headlight assemblies.
These conditions must be corrected before a satisfactory
adjustment can be made.2. Place vehicle on a level floor.
3. Bounce front suspension through three (3) oscillations
by applying body weight to hood or bumper.
4. Inspect tire inflation.
5.Rock vehicle sideways to allow vehicle to assume it.snor-
mal position.
6.If fuel tank is not full, place a weight in trunk of vehicle
7.
to simulate weight of a full tank [3 kg (6.5 Ibs.) per gallon].
There should be no other load in the vehicle other than
driver or substituted weight of approximately 70 kg (150
Ibs.) placed in driver’s position.8. Thoroughly clean headlight lenses.
9. When performing the visual headlight adjustment on ve-
hicles with resin lens headlights, be sure to observe the
following precautions.
CautionWhen adjusting one headlight, the other headlight
should be turned off if possible. If this is not possible,
do not cover the other headlight for more than threeminutes while it is turned on. Otherwise, heat from
the bulb may warp the headlight lens.
NOTE
If the visual headlight adjustment at low beam is made,
the adjustment at high beam is not necessary.

Broadcasts can be heard but both AM and FM have a lot of noise.
(1)Noise occurs when the engine is stopped.
YesJ
(2)Noise occurs when the engine in running.
Do the following measures eliminate the noise?
@ Tune to a station with a strong signal.
l Extend the antenna completely. (Whip antenna)
l Adjust the sound quality to suppress high tones.
NoIs the radio body ground mounted securely?
Yes
Securely tighten the nuts for the bodyground.
Yes
YesClean the antenna plug and ground
wire mounting area. Mount the anten-
na securely. On a vehicle with a motor
antenna, check the antenna itself. (Re-fer to E-1, 2.)
If there is more noise than other radios, consult a servicecenter
NOTE
About noise encountered during FM reception only.
Due to differences in FM and AM systems, FM is
noise interference (first fading and multipath). (Refer
to A-2.)

Repair or replace electricalcomponents.
Return parts or wiring to
their proper position.
Caution
1.Connecting a high tension cable to the noise
filter may destroy the noise filter and shouldnever be done.
2.Check that there is no external noise. Since
failure to do this may result in misdiagnosis
due to inability to identify the noise source,
this operation must be performed.3. Noise prevention should be performed by
suppressing strong sources of noise step
by step.
NOTE
1. Condenser
The condenser does not pass D.C. current, butas the number of waves increases when it
passes A.C. current, impedance (resistanceagainst A.C.) decreases, and current flow is
facilitated. A noise suppressing condenser
which takes advantage of this property is in-
serted between the power line for the noise
source and the ground. This suppresses noiseby grounding the noise component (A.C. or
pulse signal) to the body of the vehicle.
2. Coil
The coil passes D.C. current, but impedance
rises as the number of waves increases relativeto the A.C. current. A noise suppressing coil
which takes advantage of this property is in-
serted into the power line for the noise source,
and works by preventing the noise componentfrom flowing or radiating out of the line.

Ground parts by bonding.
Cases where the problem
is not eliminated by a single
response to one area are
common, due to several
bodypartsbeing
imperfectly grounded.

About multipath noise and fading noise
Because the frequency of FM waves is extreme-
ly high, it is highly susceptible to effects from
geological formations and buildings. These ef-
fects disrupt the broadcast signal and obstruct
‘reception in several ways.l Multipath noise
This describes the echo that occurs when the
broadcast signal is reflected by a large obstruc-
tion and enters the receiver with a slight time
delay relative to the direct signal (repetitious
buzzing).l Fading noise
This is a buzzing noise that occurs when the
broadcast beam is disrupted by obstructing ob-
jects and the signal strength fluctuates intricately
within a narrow range.

Raise and remove the seat cushion with the lever pulled.
INSTALLATION SERVICE POINT
.AqREAR SEAT CUSHION INSTALLATION
(1) Securely fit the attachment wire of the seat cushion
under the seatback.
(2) Pass the inner seat belt buckles through the cushion.
(3) Securely fit the lock plates of the seat cushion into
the holes in the floor.
INSPECTION
ANTENNA MOTOR INSPECTION
Disconnect the motor antenna control unit connector, connect
the positive terminal of the power supply to terminal (1) and
connect the negative terminal to terminal (4) to check that
the antenna goes up, and that when the connections are re-
versed, the antenna goes down.
MOTOR ANTENNA CONTROL UNIT INSPECTION
(1) Connect the harness connector to the motor antenna.
(Body harness)
(2) Disconnect the antenna motor connector.
(3) With the ignition switch in the ACC or ON position, operate
the radio switch and check the voltage between the termi-
nals during the period when the antenna is going up or
going down.
