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.
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
this is a early warning the brake pads need to be replaced.
