ABS light--Brake light

[hjewell2]

ok here it is, I have a 2001 chevy blazer I have just changed the front hub assemblies about 6 months ago. fluid is up to level,a little black looking but filled. my problem is sometime the brake lights stay on and the ABS light stays on. when I drive it the red warning brake light comes on and off. ABS light will go out when turning left then come back on when going straight. stays the same when turning right. The harness is all new with the hub assemblies. could it have been a bad harness with a broken wire, possible bad connecton at plug in point Please help. I can work on my 70 1/2ton but this new fangled stuff has got me by the arse.

I believe there is a GM service bulletin about this. Bad ground on ABS module.

I know this is almost 2 months old but do you or anyone have a copy of that service bulletin?
I too swapped out front hubs on my 01 and when I hit a bump they both come on.
Any help would be appreciated.
