Dunno what the JY is asking. I recommend sending it to Matt at http://www.cheapabs.com/about.html for an $85 repair. ($100 w/active braking)
He rebuilt mine. Probably send it in before you go and buy all 4 new hubs, see which are really bad.
General directions are on Matt's site. The hardest part is there's a plug on the bottom. I wedged a screwdriver in between the ABS aluminum body and the black steel mounting bracket to get the last screw.
I had trouble getting ahold of Matt through his site. This is him on ebay - http://www.ebay.com/itm/ABS-module-r...R7Sni28c76r1pg, this item is the Active Brake service http://www.ebay.com/itm/Pontiac-Gran...R7Sni28c76r1pg
Or, shoot him a text during business hours. (434) 298-4150
Cheapest shipping method is a 6x6x6 box (walmart/office store) paid with regular postage. Less than a flat rate box.
Good luck. Don't pay any shop to "reprogram" the ABS. It's plug n play.![]()
