1. A vehicle side door latch, comprising:
a remote cinching actuator;
a cinching motor located within the remote cinching actuator; and
a two-stage gear train system located within the remote cinching actuator and for performing a cinching function of the vehicle side door latch, wherein rotation of the cinching motor drives a driver gear and a driven gear, the driven gear is coupled to a cable lever mechanically attached by a cable, to a cinching lever within the vehicle side door latch, the cinching lever when moved by the cable will move a cinch drive link which is in turn attached to a bearing, that will move along with the cinch drive link, and the bearing will travel through a canal of a cinch override lever, which maintains a cinching travel course of the cinch drive link and allows an engagement of the cinch drive link with a claw of the vehicle side door latch in order to rotate the claw on its axis from a secondary position to a primary position;
a release motor embedded within the side door latch, wherein rotation of the release motor will drive a power release gear, and consequently, through a cam on the power release gear, a power release lever will be driven which will when driven will cause movement of a pawl release lever that will contact a pawl lifter, coupled to a pawl, thereby permitting the claw to rotate freely to its open position; and
a cinch override clutch link, for ceasing of the cinching function of the vehicle side door latch at any time during the cinching function;
a cinch override clutch lever that interacts with the cinch override lever, the cinch override clutch lever is coupled to the cinch override clutch link at one end of the cinch override clutch link, and the cinch override clutch link is also joined to the pawl release lever at an opposite end of the cinch override clutch link, wherein movement of the cinch override clutch link by the pawl release lever causes disengagement of the cinch drive link from the claw; and
an inside manual release lever and an outside manual release lever each operably coupled to the pawl release lever, which allows for overriding of the cinching function whether the vehicle side door latch is cinching or not.
