Abstract
A system and method for coordinating movement of a powered sliding door module and an access ramp for a vehicle. A system control board communicates with a current detector that can detect current on the power wires for the sliding door's motor. The current detector signals the system control board when it detects current and the system control board determines whether the ramp is stowed or deployed. If the ramp is deployed, the system control board stops and reverses the door so that the door remains open. The system control board then stows the ramp and closes the door. If the ramp is stowed, the system control board waits for the current in the door motor to return to zero and then determines if the door is completely open. If the door is not completely open the system control board does nothing. If the door is completely open, the system control board deploys the ramp.
