a motor;
a reduction drive operably connected to the motor;
a slippable clutch operably connected to the reduction drive;
a screw operably connected to the clutch, the clutch being structured to transmit torque between the reduction drive and the screw;
a processor; and
a memory communicably coupled to the processor and storing a tailgate control module including instructions that when executed by the processor cause the processor to:
responsive to an input, operate the motor to attempt to raise the tailgate from a fully open position to a fully closed position;
if the tailgate is in the fully closed position, discontinue operating the motor;
determine a difference between a number of motor rotation edges expected to occur during operation of the motor to raise of the tailgate from the fully open position to the fully closed position, and a number of motor rotation edges that actually occurred during raising the tailgate; and
if the difference is greater than or equal to a predetermined tolerance value,
generate an alert indicating a need for manual reset of the tailgate.
