26. INSPECT INTEGRATION RELAY OPERATION
(a) Connect the positive (+) lead from the battery to terminals
1 and 7.
(b) Connect the positive (+) lead from the battery to terminal
9 through a 3.4 W test bulb.
(c) Check that the test bulb lights up and buzzer sounds for
4 - 8 seconds when the negative (-) lead from the battery
is connected to terminal 10.
(d) Check that the buzzer sounding in (c) stops when the
negative (-) lead from the battery is connected to terminl
8.
If operation is not as specified, replace the integration relay.
27. INSPECT RELAY CIRCUIT
Remove the relay from the junction block No. 1 and inspect the
connectors on the junction block side.

INSPECTION
1. INSPECT DEFOGGER SWITCH OPERATION
(a) Connect the positive (+) lead from the voltmeter to termi-
nal 7 of connector B and the negative (-) lead from volt-
meter to terminal 10 of connector B.
(b) When the switch is off, the voltage should be approx. 12
V.
(c) When the switch is on, check that the indicator light lights
up and that the voltage is less than 1 V.
(d) After 15 minutes, check that the switch is off and the volt-
age is approx. 12 V.
2. INSPECT A/C AMPLIFIER

If continuity is not as specified, replace the relay.
4. INSPECT DEFOGGER WIRE
NOTICE:

When cleaning the glass, use a soft, dry cloth, and
wipe the glass in the direction of the wire. Take care
not to damage the wires.

Do not use detergents or glass cleaners with abrasive
ingredients.

When measuring voltage, wind a piece of tin foil
around the top of the negative probe and press the foil
against the wire with your finger, as shown.

8. Driver 's Door:
INSPECT PTC OPERATION
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the battery to terminal
9 and the negative (-) lead to terminal 10 on the wire har-
ness side connector and raise the window to the fully
closed position.
(c) Continue to apply voltage, and check that there is a PTC
operation noise within approximately 4 to 90 seconds.
(d) Reverse the polarity, and check that the window begins
to descend within approximately 60 seconds.
If operation is not as specified, replace the motor.
9. Passenger 's Door:
INSPECT PTC OPERATION
(a) Disconnect the connector from the power window switch.
(b) Connect the positive (+) lead from the battery to terminal
2 and the negative (-) lead to terminal 5 on the wire har-
ness side connector, and raise the window to the fully
closed position.
(c) Continue to apply voltage, and check that there is a PTC
operation noise within approximately 4 to 90 seconds.
(d) Reverse the polarity, and check that the window begins
to descend within approximately 60 seconds.
If operation is not as specified, replace the motor.

26 AntennaANTENNA DOES NOT FULLY EXTEND OR FULLY
RETRACT
Can you see any problem with the exterior of
the removed antenna eg. deformation, cracks?
When you extend or retract the antenna by
hand, do you feel any irregularity in its move-
ment? Remove the antenna cap. Can you remove
the antenna rod as discribed in the antenna
rod removal and replacement procedure?
Replace the antenna rod with the supplied parts
according to the antenna rod removal and re-
placement procedure.
Reinstall the removed antenna according to the antenna
rod removal and replacement procedure.
Then again check antenna rod operation using the radio
switch.
Replace fuses.
