I have a 2003 G 5AT. The slip and vdc light are both on with no check engine light or abs . I have checked brake fluid, brakes but they remain on. I don’t have loss of power or anything and the car rides just like normal. Any ideas?

 

Dealership for a diagnostic to see what chassis code is being thrown that your OBD2 scanner isn't picking up.

EDIT: Usually it's something like a bad ABS sensor on one of the wheels.
