Test No. 3: Power Window Relay Activation Circuit
When the ignition switch is switched to the ON position, and also for a period of 30 seconds after the ignition switch is switched to the OFF position, the transistor of the electronic control unit is switched ON, and battery voltage is supplied from the battery (through sub fusible link No. 2) to the power-window relay. In addition, voltage is supplied (through sub-fusible link No. 2) to the power window switch and motor as a result of the switch ON of the power window relay. See Fig 1 and Fig 2 .
