Threw code p0688 - Shutdown @ 70mph
 
ASD Relay or whatever... I found the description on various forums:
http://bit.ly/wkO4GA

I was was driving on the hwy up a hill, kicked it down a gear to 4th and about halfway up the hill my Jeep shut off. No power, oil light came on followed by the traction control light.

I was able to pull over and turn the Jeep off. It started back up and I drove home and the problem hasn't come up since.

My CONCERN here is that I've been receiving some feedback in my radio after I replaced the amp. The static will come and go and it's pretty unpredictable. My QUESTION is: "Is the static and the shutdown related?"

I recently had new spark plugs installed and the throttle body serviced. I'll definitely report back if there are any more problems but if anyone knows why or how the radio could be potentially related, I would appreciate the input.

Thank you, JG,
Ryan

electrical problems couldve caused that. Maybe a little surge or loss of signal somewhere

After searching JG, I also want to point out that I had the EGR replaced as well (finally).

Had this happen once too, Ryan. Still no clue why. Hard to bring it in w no codes on it from detuning. Haha

Did it happen more than once?

I don't go to the dealer anymore because I'm out of warranty.

Just once. On the fwy at 70mph. Luckily I'm a damn good driver and got over from the fast lane to the emergency lane. Turned the key off and she started right back up. Weird

I'm gonna tune back to stock after Vegas this weekend and wait for it to stall and then take her in n see. Weeeeee lol

I was obviously going the same speed, up and over a hill, off the freeway into a parking lot. I took power steering for granted up until that point.

Are you still under warranty?
