ABS light not working.

I have a 1993 toyota celica 2.2L GT whenever I sit in my car, put the key in and turn it to the on position all my lights come on. My battery, oil, brake for the e-brake. Check engine light, air bag light, seat belt light, and if my doors open the lil open door sign comes on. But my abs lights does not illuminate at all. Did this car not come with it or is it disconnected? How do I look. I can see where its says ABS but it doesnt light up like all the others. When I start the car all the lights go out except for the airbag that stays on until I shut the car off. I think its messed up but I was just wonderin why aint my ABS light workin. Any advice
