Key-off Operation Function Operates even if Operating Conditions are not Satisfied

DESCRIPTION
- When the driver door has not been opened and closed, each door power window regulator motor can control its power window operation for approximately 45 seconds after the ignition switch is turned from ON to off (the key is removed) by receiving operation permission signals from the main body ECU. However, when approximately 45 seconds have elapsed, or the driver door or front passenger side door is opened within approximately 45 seconds of the ignition switch being turned off (the key is removed), the power window regulator motor stops operating.
