The ECU is running quick diagnostics during this short period, just a few secs. If the surf tab toggle is switched to one side during this cycle it will cause errors. In my case it would cause the trim plate to be stuck in the down position and kill my wave.
Just turn off ignition. Make sure toggle is in center, restart and allow it to cycle before messing with anything.
