1. A drive mechanism in combination with a closure latch assembly including a latch mechanism for use in a motor vehicle having a closure member that is moveable between a fully-open position and a fully-closed position, the drive mechanism in combination with the closure latch assembly including the latch mechanism comprising:
a drive wheel including a body segment;
and a coupling lever having a first end pivotally mounted to the body segment, the coupling lever having a second end including a coupler feature adapted to engage a first portion of the closure latch assembly, an actuation cam adapted to engage a second portion of the closure latch assembly, and a follower cam adapted to engage the body segment,
wherein a driven rotation of the drive wheel in a first direction causes the follower cam to engage the body segment to move the actuation cam to tangentially engage the second portion of the closure latch assembly, and wherein a driven rotation of the drive wheel in a second direction causes the follower cam to disengage from the body segment to move the coupler feature to radially engage the first portion of the closure latch assembly;
wherein the drive mechanism is driven by a power actuator;
wherein the power actuator and the drive mechanism are configured to provide driven rotation of the drive wheel in the first direction at a first time to power actuate the latch mechanism from a primary striker capture position to a secondary striker capture position, and at a second time to power actuate the latch mechanism from the secondary striker capture position to a striker release position.
