Passenger's switch (Window lock):

SWITCH POSITION AND TESTER CONNECTION SPECIFICATION PASSENGER'S SWITCH (WINDOW LOCK)

Switch Position	Tester Connection	Specified Condition
UP	8 - 9	Continuity
OFF	8 - 10	Continuity
DOWN	9 - 10	Continuity

If the continuity is not as specified, replace the switch.

Using an ammeter:
INSPECT ONE-TOUCH POWER WINDOW SYSTEM/ CURRENT OF CIRCUIT
1. Disconnect the connector from the master switch.
2. Connect the positive (+) lead from the ammeter to terminal 3 on the wire harness side connector and the negative (-) lead to the negative (-) terminal of the battery.
3. Connect the positive (+) lead from the battery to terminal 4 on the wire harness side connector.

4. When the window moves down, check that the current is approximately 7 A.
5. Check that the current increases to approximately 14.5 A or more when the window stops moving down.
HINT:

Since the PTC opens in 4 to 90 seconds after the window stops moving down, the check must be performed before the PTC starts operating.

If the result is not as specified, replace the switch.

Using an ammeter with a current-measuring probe:
INSPECT ONE TOUCH POWER WINDOW SYSTEM/ CURRENT OF CIRCUIT
1. Remove the master switch with the connector connected.
2. Attach a current-measuring probe to terminal 9 of the wire harness side connector.
3. Turn the ignition switch ON and set the power window switch in the down position.

4. When the window moves down, check that the current is approximately 7 A.
5. Check that the current increases to approximately 14.5 A or more when the window stops moving down.
HINT:

Since the circuit breaker opens in 4 to 90 seconds after the window stops moving down, the check must be performed before the PTC starts operating.

If the result is not as specified, replace the master switch.

Driver side door:
INSPECT POWER WINDOW MOTOR OPERATION
1. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the motor turns counterclockwise.
2. Reverse the polarity, and check that the motor turns clockwise.
If operation is not as specified, replace the motor.
