If continuity is not as specified, replace the switch.
2. INSPECT POWER WINDOW SWITCH CONTINUITY
If continuity is not as specified, replace the switch.
3. Driver's Side: INSPECT POWER WINDOW MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 1 and 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.
4. Passenger's Side: INSPECT POWER WINDOW MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2. Check that the motor turns counterclockwise.
b. Reverse the polarity, check that the motor turns clockwise.
If operation is not as specified, replace the motor.
5. Using an ammeter: INSPECT ONE TOUCH POWER WINDOW SYSTEM
a. Disconnect the connector of the master switch.
b. Connect the positive (+) lead from the ammeter to terminal 4 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 9 on the wire harness side connector.
d. As the window goes down, check that the current increases to approximately 7.0 A.
e. Check that the current increases to approximately 14.5 A or more when the window stops going down.
HINT: The circuit breaker opens for some 4 - 40 seconds after the window stops going down, so that the check must be done before the circuit breaker operates.
If the operation is as specified, replace the master switch.
6. Using an ammeter with a current - measuring probe: INSPECT ONE TOUCH POWER WINDOW SYSTEM
a. Remove the master switch with the connector connected.
b. Attach a current-measuring probe to terminal 3 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 increases to approximately 7.0 A.
e. Check that the current increases to approximately 14.5 A or more when the window stops going down.
HINT: The circuit breaker opens for some 4 - 40 seconds after the window stops going down, so that the check must be done before the circuit breaker operates.
If operation is as specified, replace the master switch.
7. INSPECT CIRCUIT BREAKER OPERATION
a. Disconnect the connector from the master switch.
b. Connect the positive (+) lead from the battery to terminal 3 and the negative (-) lead to terminal 4 on the wire harness side connector, and raise the window to full closed position.
c. Continue to apply voltage and check that there is a circuit breaker operation noise within approximately 4 - 40 seconds.
d. Reverse the polarity and check that the window begins to descend within approximately 60 seconds.
If operation is not as specified, replace the motor.
8. INSPECT POWER MAIN RELAY CONTINUITY
If continuity is not as specified, replace the relay.
9. INSPECT DOOR LOCK RELAY
