Having some issues with the GXP Like the title says I'm having some issues with the GXP. For the past couple days my DIC has been flashing service vehicle soon, service ABS, service brake system, TC system off, stability system off, and the steering assist off. I think thats all of them. lol. I've scanned it and there's no engine or ABS codes in the car, and all the fuses are good. it has to be something easy, just not sure where to go next. Could there be a wheel bearing going out, or maybe a broken wire down by the wheel. Any help would be great, Thanks

Check the wiring from the ABS sensor connector to the hub itself. If they rub the axle it can wear down to the insulation and cause a short. If you see no wiring fault it is likely to be the hub but you need to have a shop pull the ABS code for you. They should be able to view the history stored code.
Normal trouble code scanners will not pull the ABS codes from these IIRC....I had to use Snap on MODUS to read my ABS codes on my 2005.

While the previous poster has a point regarding vacuum, any leak bad enough to fire those messages i8n the DIC would also manifest themselves as drivability issues and would also set a PCM code that you would have seen when you scanned it.
I'd look at the hubs and see if it's a wheel bearing or sensor wire problem.
The only other common thing that causes is this a K&N filter that's been freshly re-charged with a bit too much oil. It blows off the filter and into the MAF, which causes those messages to appear, despite no PCM codes.

do you have C.A.I system installed or any other aftermarket cold air intake system other than factory?

Think I finally got it narrowed down to the cause. It appears to be my ABS module, its getting the right volts going in but its only putting out like .9 volts. Is this common, if not that would explain why one is expensive.
My car shuts off everything too every now and then. I scanned my bcm with a tech2 and came up with two codes that were irrelevant. There is a tsb on this matter, and pontiac said to reset the tire pressure monitor in the dic (information button) I reset everything and no dice. If you have a bad sensor then the bcm will tell the tech2 which one it is. If it can't figure out which sensor it is, then the bcm will throw a seperate code. In this case, the abs module will need inspected, and all related wiring. (especially grounds) the steering wheel position sensor can also be to blame.
My car acts up when cold and is fine when hot. Something is expanding and creating continuity.
I have had this car up on the rack and inspected everything related.
I have used scanners, and am still stumped. I am in school for this ****, and nobody has answers other then "just strat replacing stuff"
