My buddy says he thinks this could be a grounding problem. There are no warning lights for faults on the dash. This is what HP Tuners reported on my car this morning. What do you guys think?

Did you clear the codes? If so, keep an eye and see if any of them come back.

Dan,
Yes he cleared them and they bounced right back up.

Don

That'* very odd. I think the first thing I would check is the plug on the PCM. Make sure it'* clean.

Edit, has this car been in a flood?

Dan,
Not been a flood that I know of. I am going to check the PCM plug tomorrow. Can I just spray it out good with wire dry?

Don

As long as it'* some kind of electro contact cleaner you should be fine.

do you have stability system errors?

No there are no fault lights at all. There are no warnings or anything.

Don

ok because all of the brake codes are indicative of a Stability System fault. these are history codes from what i can tell.

I have alot of the class 2 comm. errors, its something that is standard with the 00+ cars

I am not familiar with HP tuners, but that is what my friend used to scan this. He cleared the codes, but they popped right back up. I would have thought that with that many active errors there would be a fault on the dash. I believe the stablitrack is working because the low traction light came on the other day. I was trying to get it to come on to check the system. The owner'* manual states that if the Low Trac light comes on, stabilitrak is active.
