A control system incorporated with a power running board assembly. In particular, incorporating a radio frequency control system for a retractable power running board assembly to move the assembly between a stowed or retracted position and a deployed or extended position. The present invention uses a transmit/acknowledge scheme of door transceivers and receivers to reduce transmissions necessary to monitor door status changes and operation of the retraction and deployment of the running board, which significantly reduces the number of transmissions and wear on the door transceivers battery to extend battery lifetime.
