5 . The vehicle latch ( 1 ) as in claim 4 , wherein the control lever ( 19 ) has a feature ( 19 a ) that limits rotation of the control lever ( 19 ) with respect to the actuator housing ( 17 ) as the control lever ( 19 ) rotates with respect to the actuator housing ( 17 ) and the feature ( 19 a ) contacts a feature ( 17 a ) of the actuator housing ( 17 ).

6 . The vehicle latch ( 1 ) as in claim 5 , wherein the control lever ( 19 ) has a feature ( 19 b ) that contacts a feature ( 10 d ) of the actuator gear ( 10 ) when the actuator gear ( 10 ) rotates with respect to the control lever ( 19 ).

7 . The vehicle latch ( 1 ) as in claim 4 , wherein one end of the actuator return spring ( 18 ) is retained by a feature ( 17 a ) of the actuator housing ( 17 ) and another end is retained by a feature ( 10 c ) of the actuator gear ( 10 ).

8 . The vehicle latch ( 1 ) as in claim 4 , wherein rotation of the actuator gear ( 10 ) in first direction does not apply a force to the actuator return spring ( 18 ) and rotation of the actuator gear ( 10 ) in the second direction to the second position from the home position applies a force to the actuator return spring that causes the actuator spring ( 18 ) to spring bias the actuator gear ( 10 ) into the home position from the second position.

9 . The vehicle latch ( 1 ) as in claim 4 , wherein the lock clutch lever ( 11 ) has a leg ( 11 a ) that is positioned between feature ( 10 b ) of the actuator gear ( 10 ) and feature ( 19 b ) of the control lever ( 19 ) when the actuator gear ( 10 ) is in the home position and the control lever ( 19 ) is in the second position.

10 . The vehicle latch ( 1 ) as in claim 9 , wherein the feature ( 10 b ) contacts the leg ( 11 a ) and rotates the lock clutch lever ( 11 ) when the actuator gear ( 10 ) is rotated from the home position in the second direction and the control lever is in the second position.

11 . The vehicle latch ( 1 ) as in claim 10 , wherein rotation of the lock clutch lever ( 11 ) by feature ( 10 b ) when the actuator gear ( 10 ) is rotated from the home position in the second direction and the control lever ( 19 ) is in the second position causes rotation of the lock lever ( 13 ) operably coupled to the lock clutch lever ( 11 ) which causes rotation of a bypass lever ( 23 ) rotatably mounted to the release lever ( 14 ), a position of the bypass lever ( 23 ) determines whether rotational movement of the outside release lever ( 25 ) will cause the vehicle latch ( 1 ) to be opened.

12 . The vehicle latch ( 1 ) as in claim 1 , wherein the actuator gear ( 10 ) includes a cam face ( 10 a ) integrally formed with the actuator ( 10 ) for contacting a release lever ( 14 ) when the actuator gear ( 10 ) is rotated into the release position and the single motor ( 50 ) drives a worm ( 52 ) that meshingly engages teeth ( 54 ) of the actuator gear ( 10 ).

13 . The vehicle latch ( 1 ) as in claim 12 , wherein a control lever ( 19 ) is rotatably secured to an actuator housing ( 17 ) and the control lever ( 19 ) has a feature ( 19 a ) that limits rotation of the control lever ( 19 ) with respect to the actuator housing ( 17 ) as the control lever ( 19 ) rotates with respect to the actuator housing ( 17 ) and the feature ( 19 a ) contacts a feature ( 17 a ) of the actuator housing ( 17 ).

14 . The vehicle latch ( 1 ) as in claim 13 , wherein the control lever ( 19 ) has a feature ( 19 b ) that contacts a feature ( 10 d ) of the actuator gear ( 10 ) when the actuator gear ( 10 ) rotates with respect to the control lever ( 19 ), the feature ( 19 b ) being on one side of the control lever ( 19 ) and the feature ( 19 a ) is located on an opposite side of the control lever ( 19 ).

15 . The vehicle latch ( 1 ) as in claim 1 , further comprising:

a lock control system ( 45 ) that is placed into an unlock condition when the actuator gear ( 10 ) is rotated only the home position to the second position.

16 . The vehicle latch ( 1 ) as in claim 1 , wherein the actuator gear ( 10 ) is spring biased into the home position from the second position.

17 . The vehicle latch ( 1 ) as in claim 1 , wherein after the actuator gear ( 10 ) is rotated into the release position, the actuator gear ( 10 ) is then rotated into the second position by the single motor wherein movement of the actuator gear ( 10 ) directly from the release position to the second position does not unlock the vehicle latch such that operation of the outside release lever will not open the vehicle latch ( 1 ).

18 . The vehicle latch ( 1 ) as in claim 1 , wherein the actuator gear ( 10 ) includes a cam face ( 10 a ) integrally formed with the actuator ( 10 ) for contacting and rotating a release lever ( 14 ) when the actuator gear ( 10 ) is rotated into the release position, wherein the release lever ( 14 ) is configured to be rotated by an outside release lever when a locking mechanism ( 45 ) of the vehicle latch is in an unlocked state.

19 . The vehicle latch ( 1 ) as in claim 18 , wherein the locking mechanism ( 45 ) further comprises a bypass lever ( 23 ) rotatably mounted to the release lever ( 14 ), the bypass lever ( 23 ) operably coupling an outside release lever ( 25 ) to the release lever ( 14 ).

20 . A method for power opening and power unlocking a vehicle latch ( 1 ) with a single motor ( 50 ), comprising:

rotating an actuator gear ( 10 ) with the single motor ( 50 ) about an axis in a first direction from a home position to a release position and a second direction opposite to the first direction from either the release position or only from the home position to a second position, wherein rotation of the actuator gear ( 10 ) to the release position opens the vehicle latch ( 1 ) and rotation of the actuator gear ( 10 ) from only the home position to the second position unlocks the vehicle latch such that operation of an outside release lever will open the vehicle latch ( 1 ).
