Motor Test

Scheme 4

Scheme 5

1. Remove the door panel (see «FRONT DOOR PANEL REMOVAL/INSTALLATION»(ref-348568-S32747857942009112400000) ).
2. Disconnect the 6P connector (A) from the power window motor.
3. Test the motor in each direction by connecting battery power and ground according to the table. When the motor stops running, disconnect one lead immediately.
4. If the motor does not run or fails to run smoothly, replace it. Hall IC (Pulser) Test
5. Measure the voltage between the terminals. Common There should be battery voltage between the terminals No. 6 (No. 1)* (+) and No. 5 (No. 2)* (-) when the ignition switch is turned to ON (II). * : Front passenger's and left rear power window motor Driver's power window motor Connect an analog voltmeter between the terminals No. 2 (PLSA) (+) and No. 5 (SGND) (-), and between terminals No. 3 (PLSB) (+) and No. 5 (SGND) (-), then run the power window motor down or up. The voltmeter needle should move back and forth alternately (a digital voltmeter should show the average voltage between 0-5 V). Front passenger's power window motor/Left rear power window motor Connect an analog voltmeter between the terminals No. 5 (PLSA) (+) and No. 2 (SGND) (-), and between terminals No. 4 (PLSB) (+) and No. 2 (SGND) (-), then run the power window motor down or up. The voltmeter needle should move back and forth alternately (a digital voltmeter should show the average voltage between 0-5 V). Right rear power window motor Connect an analog voltmeter between the terminals No. 2 (PLSA) (+) and No. 5 (SGND) (-), and between terminals No. 3 (PLSB) (+) and No. 5 (SGND) (-), then run the power window motor down or up. The voltmeter needle should move back and forth alternately (a digital voltmeter should show the average voltage between 0-5 V).
6. If the voltage is not as specified, do these input tests: Driver's MPCS unit input test (see «DRIVER'S MPCS UNIT INPUT TEST»(ref-348569-S00474579182009112400000) ). Front passenger's MPCS unit input test (see «FRONT PASSENGER'S MPCS UNIT INPUT TEST»(ref-348569-S39758684502009112400000) ). Left power window switch input test (see «LEFT REAR POWER WINDOW SWITCH INPUT TEST»(ref-348569-S27922457822009112400000) ). Right power window switch input test (see «RIGHT REAR POWER WINDOW SWITCH INPUT TEST»(ref-348569-S17559205012009112400000) ).
7. If the input tests are OK, replace the power window motor.
8. Reset the power window control unit (see «RESETTING THE POWER WINDOW CONTROL UNIT»(ref-348569-S17462322062009112400000) ).

Scheme 6

1. Remove the driver's door armrest (see «FRONT DOOR PANEL REMOVAL/INSTALLATION»(ref-348568-S32747857942009112400000) ).
2. Disconnect the 6P connector (A) from the power window master switch (B).
3. Remove the four screws and the switch.
4. Install the switch in the reverse order of removal.
5. After replacement, reset the power window control unit (see «RESETTING THE POWER WINDOW CONTROL UNIT»(ref-348569-S17462322062009112400000) ).

Scheme 8

1. Remove the passenger's door armrest (see «FRONT DOOR PANEL REMOVAL/INSTALLATION»(ref-348568-S32747857942009112400000) ).
2. Disconnect the 10P (or 14P)* connector (A) from the passenger's power window switch (B). * : Rear power window switch Front Passenger's Rear
3. Remove the three screws and the switch.
4. Swap the power window switch with another known-good switch and test. If the original window switch is faulty; replace it.
5. Install the switch in the reverse order of removal.
6. After replacement, reset the power window control unit (see «RESETTING THE POWER WINDOW CONTROL UNIT»(ref-348569-S17462322062009112400000) ).
