A latch system for a door of a vehicle including a latch assembly having a catch and a pawl, an actuatable inside handle, and an actuator engaged with the pawl and being configured to be activated by actuation of the inside handle. The catch is configured to be moved to an open position by activating the actuator to thereby move the pawl to stop the pawl from maintaining the catch in the closed position. The catch is also configured to be moved to the open position after actuation of the inside handle or a toggle lever to stop the pawl from maintaining the catch in the closed position to when the vehicle does not have power.

1. A latch system for a door of a vehicle, said latch system comprising: a latch assembly for maintaining the door in a closed location, the latch assembly including a catch and a pawl, the pawl being movable between engaged and disengaged positions the catch having a closed position wherein the catch is configured to grasp a portion of the vehicle to maintain the door in the closed location and an open position wherein the catch is configured to release the portion of the vehicle to allow the door to move to an open location, the pawl being configured to maintain the catch in the closed position when the pawl is in the engaged position, the pawl being configured to permit movement of the catch to its open position;an actuatable inside handle not mechanically connected to the pawl by movable mechanical linkage capable of moving the pawl to its disengaged position;an actuator engaged with the latch assembly, the actuator being configured to be activated by actuation of the inside handle;an inside release switch activated by actuation of the inside handle, the inside release switch sending a signal to the actuator to move the pawl;a door module electronically connected between the inside release switch and the actuator, the door module selectively activating the actuator;an emergency release lever being movable between an on position and an off position, the emergency release lever being configured to be engaged with the latch assembly;wherein the catch is configured to be moved to the open position after actuation of the inside handle by activating the actuator to thereby move the pawl to stop the pawl from maintaining the catch in the closed position when the vehicle has power;wherein the catch is configured to be moved to the open position by moving the emergency release lever to the on position to thereby move the pawl to stop the pawl from maintaining the catch in the closed position when the vehicle has power and when the vehicle does not have power; andwherein the door module only activates the actuator to move the pawl after the inside handle has been actuated twice within a predetermined time period. 2. The latch system for a door of a vehicle as claimed in claim 1, wherein: the latch assembly has a locked condition wherein the pawl is prevented from releasing the catch; andif the latch assembly is in the locked condition, the actuator prevents actuation of the inside handle from actuating the pawl to stop the pawl from maintaining the catch in the closed position. 3. The latch system for a door of a vehicle as claimed in claim 1, further including: a key unlatch cylinder configured to be accessible from an exterior of the vehicle, the key unlatch cylinder being configured to be actuated after engagement with a key, the key unlatch cylinder being engaged with the pawl; andwherein the catch is configured to be moved to the open position after actuation of the key unlock cylinder to thereby move the pawl to stop the pawl from maintaining the catch in the closed position. 4. The latch system for a door of a vehicle as claimed in claim 1, wherein: the actuator is configured to be able to maintain the pawl in a stationary position whereby the pawl maintains the catch in the closed position. 5. The latch system for a door of a vehicle as claimed in claim 1, further including: an actuatable outside handle;wherein the latch assembly has a locked condition wherein the pawl is prevented from releasing the catch; andwherein the catch is configured to be moved to the open position after actuation of the outside handle by activating the actuator to thereby move the pawl to stop the pawl from maintaining the catch in the closed position when the vehicle has power and when the latch assembly is in the locked condition. 6. A method of controlling a location of a door of a vehicle comprising: providing a latch assembly for maintaining the door in a closed location, the latch assembly including a catch and a pawl, the catch having a closed position wherein the catch is configured to grasp a portion of the vehicle to maintain the door in the closed location and an open position wherein the catch is configured to release the portion of the vehicle to allow the door to move to an open location, the pawl being configured to maintain the catch in the closed position;providing an actuatable inside handle, with the actuatable inside handle not being mechanically connected to the pawl by linkage capable of causing the pawl to move;providing an actuator;engaging the actuator with the latch assembly;providing an emergency release lever being movable between an on position and an off position, the emergency release lever being configured to be engaged with the latch assembly;moving the catch to the open position by actuating the inside handle by activating the actuator to thereby move the pawl to stop the pawl from maintaining the catch in the closed position, wherein the actuator moves the pawl to stop the pawl from maintaining the catch in the closed position only if the inside handle has been actuated at least two times within a predetermined time period when the vehicle has power; andmoving the clutch to the open position by moving the emergency release lever to the on position and thereby move the pawl to stop the pawl from maintaining the catch in the closed position when the vehicle has power and when the vehicle does not have power. 7. The method of controlling a location of a door of a vehicle as claimed in claim 6, wherein: the latch assembly has a locked condition wherein the pawl is prevented from releasing the catch; andif the latch assembly is in the locked condition, the actuator prevents actuation of the inside handle from actuating the pawl to stop the pawl from maintaining the catch in the closed position. 8.
