This is likely an electrical/electronic issue; that the ABS controller has seen something that it knows or thinks cannot be. Which in-turn, shuts off the ABS system and turns the warning lights on. You’ll have to have the codes read to begin the diagnostic procedure.

You can get flash codes from this one. Here is the procedure.
Trouble codes can be accessed by connecting a TECH 1 scan tool or by manually grounding the ALDL connector. To manually ground the ALDL connector, connect a jumper wire between terminals A and H and observe the flashes of the brake warning lamp. Note the following when performing the Diagnostic Circuit Check to access trouble codes.
- When the terminals are jumped, count the number of short flashes starting from the initial long flash and including the long flash in the count.
- The count sequence will repeat as long as the ALDL connector terminals are jumped with the ignition on.
- Sometimes the first count sequence will be short. However, subsequent counts will be accurate.
- If more than one failure has occurred, only the first recognized failure code will be stored and flashed by the ECU.
- After determining the stored failure code, perform steps indicated by the diagnostic circuit check and follow the indicated failure code chart. After performing all indicated repairs, road test vehicle to check system operation, then recheck system for stored trouble codes.

Easy or hard, there is only one way and that is to resolve the issue that put the light on.
