Component Tests and General Diagnostics

INSPECTION







1. Driver's side
INSPECT POWER WINDOW CONTROL SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







2. Passenger's side
INSPECT POWER WINDOW CONTROL SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







3. Only for passenger's power window
INSPECT POWER WINDOW LOCK SWITCH CONTINUITY
If continuity is not as specified, replace the switch.

4. Driver's 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.

5. Passenger's 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.

6. Driver's door
INSPECT POWER WINDOW MOTOR PTC OPERATION




a. Disconnect the B6 connector from the body ECU.
b. Connect the positive (+) lead from the battery to terminal 5 and the negative (-) lead to terminal 4 on the wire harness side connector, and raise the window to fully closed position.




c. Continue to apply voltage, check that a circuit breaker operation noise is heard within approximately 4 to 90 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.

7. Passenger's door
INSPECT POWER WINDOW MOTOR PTC OPERATION




a. Disconnect the connector from the power window switch.
b. Connect the positive (+) lead from the battery to terminal 3 and the negative (-) lead to terminal 1 on the wire harness side connector, and raise the window to fully closed position.




c. Continue to apply voltage, check that circuit breaker operation noise is heard within approximately 4 to 90 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.
