Component Tests and General Diagnostics

INSPECTION




1. INSPECT POWER WINDOW MASTER SWITCH CONTINUITY




Front driver's switch (Window unlock and lock)




Front passenger's switch (Window unlock)




Front passenger's switch (Window lock)




Rear left switch (Window unlock)




Rear left switch (Window lock)




Rear right switch (Window unlock)




Rear right switch (Window lock)

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




2. INSPECT POWER WINDOW MASTER SWITCH ILLUMINATION
Connect the positive (+) lead from the battery to terminal 11 and the negative (-) lead to terminal 4, and check that all the illuminations light up.
If operation is not as specified, replace the master switch.







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 terminal 5 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.
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 - 40 seconds after the window 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 5 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 4 - 40 seconds after the window stops going down, so that check must be made before the circuit breaker operates.

If operation is as specified, replace the master switch.







5. INSPECT PASSENGER'S POWER WINDOW SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







6. INSPECT REAR DOOR POWER WINDOW SWITCH CONTINUITY
If continuity is not as specified, replace the switch.

7. 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, 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. 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 counterclockwise.
If operation is not as specified, replace the motor.

9. Driver's door: INSPECT POWER WINDOW MOTOR CIRCUIT BREAKER OPERATION




a. Disconnect the connector from the master switch.
b. Connect the positive (+) lead from the battery to terminal 5 and the negative (-) lead to terminal 1 on the wire harness side connector and raise the window to full closed 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.

10. Front passenger's door: INSPECT POWER WINDOW MOTOR CIRCUIT BREAKER 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 full closed 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.

11. Rear left side door: INSPECT POWER WINDOW MOTOR CIRCUIT BREAKER OPERATION
See step of Front Passenger Door Motor.

12. Rear right side door: INSPECT POWER WINDOW MOTOR CIRCUIT BREAKER OPERATION
See step of Front Passenger Door Motor.







13. INSPECT POWER MAIN RELAY CONTINUITY
If continuity is not as specified, replace the relay.

14. Key-Off power window signal: INSPECT INTEGRATION RELAY OPERATION

HINT: When the relay circuit is as specified, inspect the key-off power window signal.




a. Connect the positive (+) lead from the voltmeter to terminal 14 and the negative (-) lead to body ground.
b. Close the door with ignition switch turned to LOCK or ACC, and check that the meter needle indicates battery positive voltage.
c. Open the door and check that the meter needle indicates 0 V.




d. Turn the ignition switch ON and check that the meter needle indicates battery positive voltage again.
If operation is not as specified, replace the relay.
