If there is no transfer case lever in the floor of the truck, the t-case is fully electronic and disengagement should be immediate. Backing up about 10-15 feet might help but typically this is done more to disengage the so-called "automatic" front hubs (junk). The control module for the electronic t-case is behind the passenger side kick panel near the floor. With the electronic cases though, the most common failure point is a jammed shift motor. they often get stuck "between" shift points. When this happens, the control module "knows" it and will not send electricity to the shift motor to keep it from damaging the t-case. The only way to fix it is to either remove the shift motor, lubricate the mechanism and re-install it with the armature rotated to the 2WD position.
