Abstract: An automotive vehicle has at least one access cover movable between first and second positions and a variable position ajar sensor that senses a position of the access cover. An electronic control unit has a normal mode and a learn mode. In the normal mode, the electronic control unit is responsive to a position of the access cover sensed by the variable position ajar sensor and determines that the access cover is closed when the sensed position matches a stored closed position stored in memory of the electronic control unit and that the access cover is ajar when the sensed position does not match the stored position. In the learn mode, the electronic control unit is responsive to a position of the access cover sensed by the variable position ajar sensor and stores that position in the memory of the electronic control unit as the stored closed position.

Abstract: An electronic drive system using a plurality of drive circuits for enabling greater plurality of functions by selectively placing drive signals on the driver outputs at one of two possible polarities. At least one of the enabled functions taking a substantially shorter time for enablement, thereby allowing at least two of the plurality of functions to share a common driver output enabling signal.
