Power Window Motor: Testing and Inspection

Left 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, check that the motor turns clockwise.




b. Reverse the polarity, check that the motor turns counterclockwise.
If operation is not as specified, replace the motor.

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, check that the motor turns clockwise.




b. Reverse the polarity, check that the motor turns counterclockwise.
If operation is not as specified, replace the motor.

Driver's Door:

INSPECT CIRCUIT BREAKER 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 harness side connector raise the window to the fully closed position.
c. Continuity to apply voltage, check that there is a circuit breaker operation noise within approximately 4 to 40 seconds.




d. Reverse the polarity, check that the window begins to descend within approximately 60 seconds.

If operation is not as specified, replace the motor.

Passenger's Door:

INSPECT CIRCUIT BREAKER 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 harness side connector, and raise the window to the fully close position.
c. Continue to apply voltage, check that there is a circuit breaker operation noise within approximately 4 to 40 seconds.




d. Reverse the polarity, check that the window begins to descend within approximately 60 seconds.
If operation is not as specified, replace the motor.

Rear Door:

INSPECT CIRCUIT BREAKER OPERATION

INSPECT POWER WINDOW MOTOR CIRCUIT
a. Disconnect the connector from the motor.
b. Connect the connector to the master switch and power window switch.
c. Inspect the connector on the wire harness side.

If circuit is not as specified, inspect the circuits connected to other parts.

INSPECT THEFT DETERRENT AND DOOR LOCK CONTROL ECU CIRCUIT
a. Inspect ECU Power Source Circuit.
b. Inspect Actuator Power Source Circuit.
c. Inspect ignition Switch Circuit.
d. Inspect Door Open Detection Switch Circuit.
If circuit is as specified, inspect ECU operation.




INSPECT THEFT DETERRENT AND DOOR LOCK CONTROL ECU OPERATION
a. With the connectors connected, shut all doors.
b. Check that there is 10 V - 14 V between terminal B8 and ground when the ignition switch is turned ON.
c. After turning the ignition switch OFF, check within 60 seconds that there is battery positive voltage between terminal B8 and ground.
d. Turn the ignition switch ON then OFF, and check that there is 10 V - 14 V between terminal B8 and ground when the ignition is switched OFF.
e. Open the front door within 60 seconds of turning the ignition off and check that there is no voltage between terminal B8 and ground.
f. Close all the doors and turn the ignition switch ON.
g. When a front door is opened, check that there is battery positive voltage between terminal B8 and ground.
h. Check that there is no voltage between terminal B8 and ground when the ignition switch is turned to OFF.
If operation is not as specified, replace the ECU.
