If it has the huge ABS unit on top of the LH fenderwell, complete with it's own electric motor the size of a heater fan motor, it has 4-wheel ABS.

If rear-wheel only ABS, there is a smaller, simpler, ABS unit connected into the brake lines, hanging beneath the master cylinder.

I had a 1992 Sub with similar problem, it turned out the brake light switch (which has other contacts, also) was worn out, and was confusing the ABS computer.

I'm sure a bad wheel sensor is a likely culprit, too. You need to pull the ABS trouble codes, and see where that leads.
