It may be referred to as the EBCM. Here's a link to it:
CHEAP ABS Module Repair for Pontiac Grand Prix
I have the factory manuals, but I stopped reading when it said I needed a special scanner. I read the boards here and read how to ohm-out the wheel sensors. Then I stopped at AAMCO to get the ABS codes read.
Since I had no codes, the ABS/Trac light, and the wheel sensors appeared to work, I was told it was probably the module.
I sent the module out to cheapabs.com and got it back and it's been running 2 days so far (fingers crossed)
