My antilock brakes stoped working a few weeks ago. happened all of a sudden and it was during a rainstorm and the "ABS INOP" message came on. It was never intermittent or anything so i think that it is something electrical. Anybody have any ideas about this? anything would be helpfull. 1998 trans am six speed incase it matters.

 

A dealership can read the code and tell you what's failing. There's probably close to 40 codes.
