A system and method are disclosed for back up control of a towed-vehicle. The system may include a back up detector, at least one misalignment sensor, a controller, and a misalignment responder. The misalignment responder turns the steering wheel of a towed-vehicle. The system may further include a wireless transmitter to communicate signals between a towing-vehicle and the towed-vehicle. A misalignment signal may be produced by the misalignment sensor when a relative angle between the towing-vehicle and the towed-vehicle exceeds a relative angle threshold. The system may further include a monitoring device in the towing-vehicle to provide an indication of jackknifing and that a towed-vehicle's battery power is low.
