3. Using an ammeter:
INSPECT ONE TOUCH POWER WINDOW SYSTEM/
CURRENT OF CIRCUIT
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the ammeter to termi-
nal 9 on the wire harness side connector and the negative
(-) lead to negative terminal of the battery.
(c) Connect the positive (+) lead from the battery to terminal
10 on the wire harness side connector.
(d) As the window goes down, check that the current flow is
approximately 7 A.
(e) Check that the current increases up to approximately
14.5 A or more when the window stops going down.
HINT:
The circuit breaker opens some 4 - 90 seconds after the win-
dow stops going down, so that check must be made before the
circuit breaker operates.
If the operation is as specified, replace the master switch.
4. Using an ammeter with a current-measuring probe:
INSPECT ONE TOUCH POWER WINDOW SYSTEM
CURRENT OF CIRCUIT
(a) Remove the master switch with connector connected.
(b) Attach a current-measuring probe to terminal 4 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 flow is
approximately 7 A.
(e) Check that the current increases up to approximately
14.5 A or more when the window stops going down.
HINT:
The circuit breaker opens some 9 - 90 seconds after the win-
dow stops going down, so that check must be made before the
circuit breaker operates.
If operation is as specified, replace the master switch.

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

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.
