ABS light remains on in driver's dash on 1992 Acura Vigor

Upon start up and their is no ABS when I apply a hard brake stop application. I have already checked fuses and relays for ABS module. Does anyone have any other suggestions.

Thanks In Advance

Try cleaning the wheel speed sensors and the sensor rings.

this is a early warning the brake pads need to be replaced.
Could also be a brake light; mine had corrosion in the socket that prevented a consistent connection; you can test by slightly moving each of the bulbs while looking through the rear glass to see if the abs light goes out
