The other day I was sitting in line at Taco Bell. My V started beeping, and saying stabilitrac off, and service stabilitrac. The gauges were bouncing up and down, then the check engine light came on.
Codes P0700 and U0073
The car went into limp mode and would not shift gears. The engine still ran smooth.
I spoke with a friend who suggested it may be a bad ground somewhere. I looked around at what I could find, mad sure connections on the ECM were seated properly, checked to make sure the main ground line was tight. Everything looked of.

Is my computer gone?
Is there possibly some other issue?
Anyone else experienced this?
