Abstract

An electrical latch for a closure system of a motor vehicle and method of operating are provided. The electrical latch includes a latching mechanism having a pawl and ratchet, a cinching mechanism having a cinching lever, and an electric actuator mechanism for actuating at least the cinching lever. The electrical latch further includes a control unit powered by a main power source and having a control circuit controlling operation of the actuator mechanism to affect the position of the cinch lever, and a backup energy source providing power to the control circuit and the actuator mechanism in the event a fault condition is experienced by the main power source. The electrical latch is configured to return the cinching lever to a home uncinched position in response to switching of power from the main power source to the backup energy source.
