ABS,Service vehicle, trac off lights on on 2001 Pontiac Grand Am

ABS keep coming on at random times not just at braking, have had 3 wheel bearings replaced now the repair place said something is causing them to go out and thats why the lights are on but when they check to see why the lights are on it shuts the tester down

How long are the new wheel bearing/sensor lasting before the lights come back on? Are they setting fault code(s) for a wheel speed sensor? The same on every time?

I am still having this problem now at about 6 or 7 wheel bearings and 3 from a second repair place which keeps telling me it is becasue of how they are made and where they are located on the 2001 grand am, I talked to someone and they thought maybe the wiring could be the problem and its not the bearings themselves? They have been back on for about 3 months again now when backing out and put it in drive low trac comes on and its like its trying to stall but then goes off once I get going.

I own a 99 Pontiac Grand Am SE. When I pull out the low trac light will sometimes, not always, come on. Then when I am driving down the road the ABS and the trac off lights come on at the same time...
I change the wheel hub bearing but still make too much rumble noise.
