What is the part number for an ABS module for this car and when the ABS light

What is your question?

comes on and stays on, besides the sensor being bad or the module and the wiring is good, what else could cause that light to stay on and would the regular brake light stay on as well even though brakes are fine and it is just the ABS system? Please reply back ASAP, this is for my electric wheelchair converted minivan in the shop now. Thank you so much. Lesa Foster
