Step one is to retrieve the fault codes using a scan tool. An Abs light can come from about 30 different codes from module or control unit issues or speed sensor issues or base brake concerns. Since you have both lights coming on the first thing I would look at is the brake fluid level switch, try unplugging it and jumping the 2 wires together to bypass the switch assuming the fluid level is not low which would be the cause.
