Abstract

A power latch assembly for a vehicle door and method of construction thereof is provided. The power latch assembly includes a pawl configured for movement between a ratchet holding position whereat the pawl maintains a ratchet in a striker capture position and a ratchet releasing position whereat the pawl releases the ratchet to a striker release position. A pawl release lever moves the pawl between the ratchet holding position and the ratchet releasing position. A powered actuator is energizable to control movement of the pawl release lever, wherein upon the pawl reaching the ratchet releasing position, the powered actuator is automatically de-energized without a hard stop feature.
