dead PCM?

So i was driving down the road and all the sudden it was like the engine just cut out, it was actually still running but the traction control f'd up... immidiately after i got a check engine light, traction off light, and now the messages service suspension, service traction control, and service stibilitrak are on... any ideas? should i just bring it to the junk yard now or later? 07 denali with 58k on it so its probably about ready for the junk yard anyways, lol WTF!!!!

Hope you have an extended warranty

I doubt its much of an issue, that once happened to me, except it went away after 2miles, I was already on my way to the dealer haha.
Also when I serviced the trucks intake, I forgot to replug the MAF harness tot he sensor and I was having the exact same issues, but figured it out after I drove around the block once.
Lastly, check to make sure all you ARS sensor plus are intact and plugged in behing each wheel/tire.

Dude. I got two of those messages- albeit intermittently on a 05 yukon slt- i got one of those code clearers and traded it in and still got near 16k for it with 100k miles- i also bought a 10 denali which i love- i would try the same thing just abort!!!!

lol, back to normal (kinda) now... i went to a touch free car wash right before that happened so mabey the high pressure water got into something? However, now i still have the check engine light on, not sure if there is still an issure or if its staying on because of all the codes that were pulled earlier. Can i clear the light myself? or do i have to take it to a stealership?

I had a freaky occurrence with a drive thru wash in an 03 Denali... the speedometer went haywire and went all the way around and got stuck in between drive and neutral
