Hi, welcome to the site.
Do you remember what code it was?
If both the ABS light and the brake light are on it could be corroded ground wires, as both the ABS module and the brake fluid level sensor use the same ground (G110) located on the passenger side chassis rail. If the wires are corroded the fix is cutting off the eyelet, stripping the wires back to good metal and adding a new eyelet.
