26 Noise NOISE OCCURS
No
Ye s
NG
OK Does the noise occur only in the radio?
Does the noise occur in a particular place?
Is there any additional installation part
around the glass imprinted antenna?
(Sun shade film, telephone antenna etc.)
Does the noise occur even pulling out the
antenna cord from the radio?
Does the noise occur even after pulling out the
antenna terminal on the glass surface?
Isn't there any adhesive (Butyl rubber)
stuck on the bases of the antenna
terminal, defogger terminal and bus bar?
Check the grounding of the antenna,
antenna cord, coke coil, and noise filter.
(See page BE-126) Does the noise occur even after pulling out
the defogger terminal?
Does the condition get better by replacing
the antenna cord.
Noise rediates directly to the antenna from the
generation source. Does the condition get better by replacing
the choke coil?
Replace the antenna cord. Replace the choke coil. Interfering noise from the defogger line
and choke coil.
Grounding failure. Failure of glass installation.
Must plane the butyl rubber. Noise mixing into the antenna cable. Check the radio. Influence of the film or the noise radiation
of the additional installation part. Does the noise stop by removing it? An electric environment.Refer to No.27. (It occurs in the cassette and CD.)

Measure the resistance between terminals with fixing pointer to
the stopper.
Tester connectionResistance (W)
A - B250
C - D250
If resistance value is not as specified, replace the meter.
9. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the main sender gauge.
(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.
(c) Connect terminals 2 and 3 on the wire harness side con-
nector through a 3.4 W test bulb.
(d) Turn the ignition switch ON, check that the bulb lights up
and receiver gauge needle moves toward the full side.
HINT:
Because of the silicon oil in the gauge, it will take a short time
for needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.

ER GAUGE RESISTANCE
Connect the wire harness as shown in the illustration, and ad-
just the ammeter pointer to indicate º0º using the slide rheostat,
then read the rheostat indication.

120 (248.0)17.1 - 21.2
If resistance value is not as specified, replace the engine cool-
ant sender gauge.
16. INSPECT LOW OIL PRESSURE WARNING LIGHT
(a) Disconnect the connector from the warning switch and
ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON, check that the warning light
lights up.
If the warning light does not light up, test the bulb or inspect wire
harness.
17. INSPECT LOW OIL PRESSURE WARNING SWITCH
OPERATION
(a) Check that continuity exists between the terminal and
ground with the engine stopped.
(b) Check that no continuity exists between the terminal and
ground with the engine running.
HINT:
Oil pressure should be over 29 kPa (0.35 kgf/cm
2, 4.3 psi)
If operation is not as specified, replace the switch.
18. INSPECT BRAKE WARNING LIGHT
(a) Disconnect the connector from the brake fluid warning
switch.
(b) Release the parking brake pedal.
(c) Connect the terminals on the wire harness side of the lev-
el warning switch connector.
(d) Start the engine, check that the warning light lights up.
If the warning light does not light up, test the bulb or wire har-
ness.

6. Stopping at stop position:
INSPECT WIPER MOTOR OPERATION
(a) Operate the motor at low speed and stop the motor opera-
tion anywhere except at the stop position by disconnect-
ing positive (+) lead from terminal 3.
(b) Connect terminals 1 and 5.
(c) Connect the positive (+) lead from the battery to terminal
2 and the negative (-) lead from the battery to the motor
body or terminal 4, and check that the motor stops run-
ning at the stop position after the motor operates again.
If operation is not as specified, replace the motor.
7. INSPECT WASHER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 2 and
the negative (-) lead to terminal 1, check that the motor oper-
ates.
NOTICE:
These tests must be performed quickly (within 20 seconds)
to prevent the coil from burning out.
