A system includes a controller and a sensor. The controller transmits a
panel control signal to a motor for the motor to move a movable panel of
a vehicle along a path between opened and closed positions while the
motor receives power from a power source. The motor receives power from
the power source upon receiving the panel control signal. The sensor
detects objects in the path without monitoring the motor. The sensor
generates an object signal indicative of an object being detected in the
path of the panel. When the panel is moving in a closing direction, the
controller transmits a panel control signal to the motor to reverse
movement of the panel to an opening direction upon receiving the object
signal in order to prevent the panel from entrapping an object. The
controller communicates with vehicle modules over an in-vehicle local
area network (LAN).
