I have a 2010 Silverado Z71 - This problem has me quite concerned that I'm getting into a pricey Easter egg hunt for an electrical issue. I hope somebody can help get me pointed into the right direction.

When I started my truck today, the entire thing glitched out. Instrument panel needles were waiving erratically, I had an 3x error ("service Stabilitrak", "Service Traction Control", and "service AWD"), and as I drove, the transmission was stuck in 1st gear - with the speedometer & tachometer bouncing around wildly. I read the errors, and had all of the following: U0100, P069E, P0700, U0073, U0101, U0102, U0109. I turned the truck off and back on and the errors remained - I erased the codes with the ODB reader and everything worked fine. I had to get to an appt, so I left hoping it was all over. I looked up all the codes and noted that basically 5 or more of the computers under the hood are not talking with each other.

Next time I start my truck, all of the same things happened. This time, two (minor?) differences. First, the instrument cluster all stayed in the "dead" position - no waving. Second, when I try to read the codes, my ODB reader says "No Link". I turned off and back on the truck several times, and every time I got the "No Link" and was unable to reset the codes. I unplugged the battery for 30 seconds to reset the warnings. Once reset, the truck operated properly again to get me home.

Any ideas where I need to start? I work an hour away from home and don't want to get stranded there (or half way there).

Thanks for the help!

i have the same issues and codes, I don’t want to start replacing things if it won’t fix the main issue. Have you ever found out what it is? I’ve been looking in a bunch of different forums and I still can’t find an answer. Let me know if you found anything out, thank you.

 

[QUOTE=Nocigar;459041]Check your battery out throughy. Do not depend on the auto parts stores to do so. If it's OK, or you buy a new one and still have these issues, then post back here.
