A vehicle latch including a ratchet (18), a first pawl (20), a cam (22), a second pawl (24) and a drive mechanism (50,52,54,56,58). The ratchet is movable between a striker (12) release position wherein the ratchet is positioned to receive a striker, and a striker holding position wherein the ratchet is positioned to retain the striker. The ratchet is biased to the striker release position. The first pawl is movable between a ratchet locking position wherein the first pawl is positioned to hold the ratchet in the striker holding position, and a ratchet release position wherein the first pawl permits the movement of the ratchet out of the striker holding position. The first pawl is biased towards the ratchet locking position. The cam is operatively connected to the first pawl, wherein the cam is movable between an first pawl enabling position in which the first pawl is enabled to move to the ratchet locking position, and a first pawl disabling position in which the cam positions the first pawl in the ratchet release position. The cam is biased towards the first pawl disabling position. The second pawl is movable between a cam locking position in which the second pawl is positioned to hold the cam in the first pawl enabling position, and a cam release position wherein the second pawl is positioned to permit the movement of the cam to the first pawl disabling position. The second pawl is biased towards the cam locking position. The drive mechanism is configured for moving the second pawl into the cam release position.
