Even after the ignition is switched off, the ETACS-ECU keeps the power window relay activated for approximately 30 seconds, enabling raising or lowering of the power windows by using the power window switches (timer function). After approximately 30 seconds, the power window relay is deactivated.

During this timer operation, if the driver's or front passenger's door is opened, the power window relay is deactivated from that moment.
