Master warning light comes on with hard acceleration.

[Fomer_FJ_owner805]

My 16 trail gets the master warning light and beeps on fast accelerations from a stand still and sometimes on a large dip, all on flat surfaces. All doors checked, fluids fine, code scanner didn't show any errors. It flashes different amount of times and the turn indicators also flash, buts one to five seconds.

Might be the hill start assist. Mine will come on sometimes on flat surfaces, but with wet pavement.
