Pulser Test

  1. Reconnect the 6P connector to the window motor, and reconnect the 20P connector to the power window master switch.
  2. Check for voltage between the terminals.
    • There should be battery voltage between the No. 6 (+) and No. 4 (-) terminals when the ignition switch is turned ON (II).
    • Connect an analog voltmeter between the No. 5 (+) and No. 4 (-) terminals, and run the window motor down or up. The voltmeter needle should move back and forth alternately between 0 V and about 5 V (a digital voltmeter should show about 2.5 V).
    • Connect an analog voltmeter between the No. 3 (+) and No. 4 (-) terminals, and run the window motor down or up. The voltmeter needle should move back and forth alternately between 0 V and about 5 V (a digital voltmeter should show about 2.5 V).
  3. If the voltage is not as specified, replace the driver's power window motor.
