1. A latch system for a closure panel of a vehicle, the latch system comprising:
a power actuator;
a ratchet configured for pivoting movement between at least one closed position and an open position, wherein the ratchet is biased toward the open position;
at least one pawl configured in operable communication with the power actuator via a mechanically actuatable first cable and being configured for pivoting movement between at least one locking position relative to the ratchet and at least one unlocking position relative to the ratchet in response to movement of the first cable via selective powered actuation of the power actuator; and
a cinch lever configured for operable communication with the power actuator via a second cable and being configured for pivoting movement between a released, uncinched position and an actuated, cinched position in response to movement of the second cable via selective actuation of the power actuator, the cinch lever being biased toward the released, uncinched position;
wherein the first cable and the second cable are operably coupled to a common gear, the common gear having a home position and being rotatable from the home position in a first direction whereupon the at least one pawl is caused to pivot between the at least one locking position and the at least one unlocking position, and the common gear being rotatable from the home position in a second direction opposite the first direction, whereupon the cinch lever is caused to pivot between the released, uncinched position and the actuated, cinched position; and
wherein the at least one pawl includes a primary pawl having a primary locking position and a primary unlocking position, included in the at least one locking position and the at least one unlocking position, respectively, and a secondary pawl having a secondary locking position and a secondary unlocking position included in the at least one locking position and the at least one unlocking position, respectively, wherein the primary pawl moves from the primary locking position to the primary unlocking position via the first cable upon a first actuation of the power actuator causing a first rotation of the common gear from the home position in the first direction and wherein the secondary pawl moves from the secondary locking position to the secondary unlocking position via the first cable upon a second actuation of the power actuator causing a second rotation of the common gear from the home position in the first direction.
