pull the dash and take out the warning lights

 

@cappedup first of ignore @disco96sd hiding lights is not even a good ha ha suggestion a lot of buyers have been screwed over by that crap

If you look behind each tire you will see a yellow connector that is the ABS speed sensor connection, pull it apart make sure the connection are tight and clean then put it back together. You could add a BIT of electrical conductivity grease just to the lower 3rd of each of the metal pins.
While you are at jack the tire up and check your wheel hub, you will have to look it up but there it just requires moving the tire around and feeling for "looseness"
Finally visually inspect your brake pads for damage other issues

Some code readers can display the data but rough road is generally a loose connector/Frayed wire/failing sensor in the hub
