ABS scanner, where to go?

My ABS Light comes on whenever I turn the wheel more than 180 degrees, I replaced both a few months back for the same issue (well, one had a bad bearing… one had a bad sensor).

99 Grand Am.
Need the ABS Scanned to figure out which side it is.
Called around and most places want $72-79.
:\

Since both hubs are under warranty I’d be better off just replacing both than pay that -.-’

Anyone able to?

edit;
I also need the ignition timing set properly, from when I installed a new PCM.

$75 if you can do both.
ASAP preferably.

How is ignition timing off with just a pcm swap??

meh, i meant the ckp variable learn.
