Pulser Test
- Reconnect the 6P connector to the window motor, and reconnect the 20P connector to the power window master switch.
- Turn the ignition switch to ON(ll).
- Measure voltage between the terminals at the driver's power window motor.
- 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).
- If the voltage is not as specified, do the power window master switch input test at the appropriate terminals: No. 5, 6, 8, and 13. Refer to Power Window Master Switch Input Test
- If the switch is OK, replace the power window moter.
- Reset the power window control unit. Refer to Resetting the Power Window Control Unit
