1. A closure latch system for a vehicle door, comprising:
a closure latch assembly having a latch mechanism including a ratchet and a pawl, the ratchet being moveable between a striker capture position and a striker release position, the pawl being moveable between a ratchet holding position whereat the pawl holds the ratchet in its striker capture position and a ratchet releasing position whereat the pawl permits the ratchet to move to its striker release position;
a power release mechanism moveable by an actuator between a home position, whereat the pawl can be moved from the ratchet holding position to the ratchet releasing position upon a single actuation of the power release mechanism, and at least one of a double pull lock position and child lock position, whereat the pawl cannot be moved from the ratchet holding position to the ratchet releasing position upon a single actuation of the power release mechanism or upon a single actuation of an inside release member; and
an emergency backup mechanism configured in mechanically coupled communication with the latch mechanism, wherein actuation of the emergency backup mechanism from a non-deployed position to a deployed position causes the pawl to move from the ratchet holding position to the ratchet releasing position regardless of the position of the power release mechanism, wherein the emergency backup mechanism has a preload bias imparted thereon to prevent rattling noise while in the non-deployed position, wherein the emergency backup mechanism has a cable assembly mechanically coupled to a release lever of the latch mechanism, wherein the bias is imparted on the cable assembly, and wherein the cable assembly includes an outer tubular cable conduit and a central cable extending along a cable axis through the outer tubular cable conduit, the bias being imparted on the central cable.
