Ive put my suspension back on and my Traction control light and my ABS light is lit, could this be just because the fluid is slightly low (wasnt on before) or could there be a sensor fault on from the 2x sensors on the steerig nuckles.

I havent started it yet as Im having to drll and re-tapp the holes on the upper zorst header (studs refused to come out )

Would this possibly clear once the engine has been started?
