It means you have gone faster than surfgate is designed for and is bringing the gate back to stowed position. Usually happens when people forget to turn surfgate off when done surfing, then throttle to normal speeds
Incorrect Dave Diaz. This is not the error you get when exceeding the max speed. Max current draw error is likely caused as Aric suggested by a Ram that will need to be replaced. The Lenco worm drive rams do occasionally leak and once water is in the ram its only a matter of time till it fails.
