Component Inspection

INSPECTION




1. INSPECT POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY

a. Using an electrical tester, check if the diodes are functioning normally.




Standard: Power window lock switch




b. Using an electrical tester, check if the diodes are functioning normally.

HINT:
- As the switch has diodes, a resistance inspection cannot be performed. Use the tester's diodes check function to check the diodes.
- Connect the tester's leads as shown in the table. If the leads are not connected correctly, the readings will not be accurate. Connect the tester's positive (+) lead to the diode's positive (+) side, and the negative (-) lead to the diode's negative (-) side.

1. Set the function selector switch to diode check function mode, and check that the diodes are functioning normally.














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




c. Check the window lock switch.

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

2. INSPECT POWER WINDOW REGULATOR SWITCH ASSEMBLY




a. Remove the switch.
b. Measure the resistance of the switch when the switch is operated.




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

3. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (DRIVER SIDE)




a. Check operation of the regulator motor.
1. Remove the motor.
2. Apply battery voltage to the motor terminals.

NOTE: Do not apply voltage to the terminals except 4 and 5.




3. Check that the motor operates smoothly.




b. Check the PTC operation inside the regulator motor.

NOTE: The work must be performed with the power window regulator and door glass installed in the vehicle.

1. Disconnect the driver side power window regulator motor connector.
2. Connect the ammeter's positive (+) lead to terminal 5 (D) of the wire harness side connector and the negative (-) lead to the battery's negative terminal.
3. Connect the battery's positive (+) lead to terminal 4 (U) of the wire harness side connector, and raise the window to the fully closed position.
4. Continue to apply voltage, and check that the current changes to less than 1 A within 4 to 90 seconds.
5. Disconnect the leads from the terminals.
6. Approximately 60 seconds later, connect the battery's positive (+) lead to terminal 5 (D) and the negative (-) lead to terminal 4 (U). Check that the window begins to descend.
If the result is not as specified, replace the motor assembly.

4. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (PASSENGER SIDE)




a. Check operation of the regulator motor.
1. Remove the motor.
2. Apply battery voltage to the motor terminals.

NOTE: Do not apply voltage to the terminals except 4 and 5.




3. Check that the motor operates smoothly.




b. Check the PTC operation inside the regulator motor.

NOTE: The work must be performed with the power window regulator and door glass installed in the vehicle.

1. Disconnect the driver side power window regulator motor connector.
2. Connect the ammeter's positive (+) lead to terminal 4 (U) of the wire harness side connector and the negative (-) lead to the battery's negative terminal.
3. Connect the battery's positive (+) lead to terminal 5 (D) of the wire harness side connector, and raise the window to the fully closed position.
4. Continue to apply voltage, and check that the current changes to less than 1 A within 4 to 90 seconds.
5. Disconnect the leads from the terminals.
6. Approximately 60 seconds later, connect the battery's positive (+) lead to terminal 4 (U) and the negative (-) lead to terminal 5 (D). Check that the window begins to descend.
If the result is not as specified, replace the motor assembly.

5. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (REAR LH)




a. Check operation of the regulator motor.
1. Remove the motor.
2. Apply battery voltage to the motor terminals.

NOTE: Do not apply voltage to the terminals except 4 and 5.




3. Check that the motor operates smoothly.




b. Check the PTC operation inside the regulator motor.

NOTE: The work must be performed with the power window regulator and door glass installed in the vehicle.

1. Disconnect the driver side power window regulator motor connector.
2. Connect the ammeter's positive (+) lead to terminal 1 (D) of the wire harness side connector and the negative (-) lead to the battery's negative terminal.
