INSPECT REAR RH DOOR PTC THERMISTOR OP-
ERATION
(a) Connect the positive (+) lead from the battery to terminal
3 and the negative (-) lead to terminal 4.
(b) Attach a current-measuring probe to either the positive
(+) lead or the negative (-) lead, and check that the cur-
rent changes from approximately 3.2 A to less than 0.5 A
within 20 to 70 seconds.

INSPECTION
1. 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 1 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
14 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 PTC opens some 4 - 90 seconds after the window stops
going down, so that check must be made before the PTC oper-
ates.
If the operation is as specified, replace the driver door ECU.
2. Using an ammeter with a current-measuring probe:
INSPECT ONE TOUCH POWER WINDOW SYSTEM/
CURRENT OF CIRCUIT
(a) Remove the driver door ECU with connectors connected.
(b) Attach a current-measuring probe to terminal 25 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 PTC opens some 4 - 90 seconds after the window stops
going down, so that check must be made before the PTC oper-
ates.
If operation is as specified, replace the driver door ECU.

7. Rear Left Side Door:
INSPECT POWER WINDOW MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (-) lead to terminal 1, and check that
the motor turns clockwise.
(b) Reverse the polarity, check that the motor turns counter-
clockwise.
If operation is not as specified, replace the motor.
8. Rear Right Side Door:
INSPECT POWER WINDOW MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and the negative (-) lead to terminal 2, and check that
the motor turns clockwise.
(b) Reverse the polarity, check that the motor turns counter-
clockwise.
If operation is not as specified, replace the motor.
9. Driver 's door:
INSPECT POWER WINDOW MOTOR PTC THERM-
ISTOR OPERATION
(a) Disconnect the connector from the power window motor.
(b) Connect the positive (+) lead from the ammeter to termi-
nal 2 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
1 on the wire harness side connector, and raise the win-
dow to the fully position.

NOTICE:
Never, ever be caught any part of your body when check-
ing.
HINT:

after repeating up and down of the glass with automatic opera-
tion.
(a) Confirmation of AUTO up operation:
Confirm that the window will be fully close with AUTO up
operation.
(b) Checking of the operation of the jam protection function:
(1) Move up the window with AUTO up operation and
check that the window will go down when it touches
the handle of the hammer stetted.
(2) Confirm that the window will then stop going down
