Power Window Motor Test

Motor Test 

1. Remove the door panel (see FRONT DOOR PANEL REMOVAL/INSTALLATION ).
2. Disconnect the 6P connector (A) from the power window motor.

3. Test the motor in each direction by connecting battery power and ground as shown (see Fig 2). When the motor stops running, disconnect one lead immediately.

4. If the motor does not run or fails to run smoothly, replace it.

   Pulser Test 

5. Measure the voltage between the terminals.

   Common

   There should be battery voltage between the No. 6 (No. 1)* (+) and No. 5 (No. 2)* (-(terminals when the ignition switch is ON (II).

   * : Front passenger's and left rear power window motor

   Driver's power window motor

   Connect an analog voltmeter between the No. 2 (PLSA) (+) and No. 5 (SGND) (-) terminals, and between No. 3 (PLSB) (+) and No. 5 (SGND) (-) terminals, 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 No. 5 (PLSA) (+) and No. 2 (SGND) (-) terminals, and between No. 4 (PLSB) (+) and No. 2 (SGND) (-) terminals, 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 No. 2 (PLSA) (+) and No. 5 (SGND) (-) terminals, and between No. 3 (PLSB) (+) and No. 5 (SGND) (-) terminals, 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  ).
   • Front passenger's MPCS unit input test (see FRONT PASSENGER'S MPCS UNIT INPUT TEST  ).
   • Left power window switch input test (see LEFT REAR POWER WINDOW SWITCH INPUT TEST  ).
   • Right power window switch input test (see RIGHT REAR POWER WINDOW SWITCH INPUT TEST  ).
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  ).
