(d) As the window goes down, check that the current in-
creases to approximately 7.0 A.
(e) Check that the current increases to approximately 14.5 A
or more when the window stops going down.
HINT:
The circuit breaker opens some 4 − 40 seconds after the win-
dow stops going down, so that the check must be made before
the circuit breaker operates.
If the operation is as specified, replace the master switch.
6. Using an ammeter with a current−measuring probe:
INSPECT ONE TOUCH POWER WINDOW
(a) Remove the master switch with connector connected.
(b) Attach a current−measuring probe to terminal 3 of the
wire harness.
(c) Turn the ignition switch ON and set the power window
switch in the down position.
(d) As the window goes down, check that the current in-
creases to approximately 7.0 A.
(e) Check that the current increases to approximately 14.5 A
or more when the window stops going down.
HINT:
The circuit breaker opens some 4 − 40 seconds after the win-
dow stops going down, so that the check must be made before
the circuit breaker operates.
If operation is as specified, replace master switch.
7. INSPECT CIRCUIT BREAKER OPERATION
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the battery to terminal
3 and the negative (−) lead to terminal 4 on the wire har-
ness side connector, and raise the window to full closed
position.
(c) Continue to apply voltage, check that there is a circuit
breaker operation noise within approximately 4 − 40 se-
conds.
(d) Reverse the polarity, check that the window begins to de-
scend within approximately 60 seconds.
If operation is not as specified, replace the motor.

If circuit is as specified, inspect the door lock signal and key−off
power window signal.
9. Door Lock Signal:
INSPECT DOOR LOCK CONTROL RELAY
HINT:
When the relay circuit is as specified, inspect the door lock sig-
nal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 1 and the negative (−) lead to terminal 6.
(c) Set the door lock control switch to UNLOCK, check that
the voltage rises from 0 V to battery positive voltage for
approximately 0.2 seconds.

(d) Reverse the polarity of the voltmeter leads.
(e) Set the door lock control switch to LOCK, check that the
voltage rises from 0 V to battery positive voltage for
approximately 0.2 seconds.
If operation is not as specified, replace the relay.
10. Key−off Power Window Signal:
INSPECT DOOR LOCK CONTROL RELAY
HINT:
When the relay circuit is as specified, inspect the key−off power
window signal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 5 and the negative (−) lead to terminal 11.
(c) Close the door with ignition switch turned to LOCK or
ACC, check that the meter needle indicates battery posi-
tive voltage.
(d) Open the door, check that the meter needle indicates 0 V.
(e) Turn the ignition switch ON, check that the meter needle
indicate battery positive voltage again.
If operation is not as specified, replace the relay.

INSPECTION
1. INSPECT ANTENNA MOTOR
(a) Connect the positive (+) lead from the battery to terminal
1 and the negative (−) lead to terminal 2.
(b) Check that the motor turns (moves upward).
NOTICE:
These tests must be done quickly (within 3 − 5 seconds) to
prevent the coil from burning out.
(c) Then, reverse the polarity, check that the motor turns the
opposite way (moves downward).
NOTICE:
These tests must be done quickly (within 3 − 5 seconds) to
prevent the coil from burning out.
2. INSPECT ANTENNA MOTOR CONTROL RELAY CIR-
CUIT
Disconnect the connector from the relay and inspect the con-
nector on wire harness side, as shown in the chart below.

REPLACEMENT
1. REMOVE ANTENNA ROD
HINT:
Perform this operation with negative (−) cable connected to the
battery terminal.
(a) Turn the ignition switch to ”LOCK” position.
(b) Remove the antenna nut.
(c) Press the ”AM” buttons on the radio receiver, and simulta-
neously turn the ignition switch to ”ACC” position.
HINT:
The rod will extend fully and be released from the motor
antenna.
After removing the antenna rod, leave the ignition switch
as ”ACC”.
NOTICE:
To prevent body damage when the antenna rod is released,
hold the rod while it comes out.
2. INSTALL ANTENNA ROD
(a) Insert the cable of the rod until it reaches the bottom.
HINT:
When inserting the cable, the teeth on the cable must face to-
ward the front of the vehicle.
(b) Wind the cable to retract the rod by turning the ignition
switch to ”LOCK” position.
HINT:
If the ignition switch is already in ”LOCK” position, perform
step 1 (c) first, then turn the ignition switch to ”ACC” posi-
tion.
In case the cable is not wound, twist it as shown in the il-
lustration.
Even if the rod has not retracted fully, install the antenna
nut and inspect the antenna rod operation. It will finally re-
tract fully.
(c) Inspect the antenna rod operation by pushing the radio
wave band select buttons.
