Good day,

I haven't had my car on the road for very long, so excuse me if this sounds crazy... Did you happen to swap out the rear diff for a different gear ratio? Generally, that would tell the stability control the RPM's and speed don't match, but I would also think that would throw a code...

The only other thing I can think of is you have a tone ring on one of the wheels starting to go... It doesn't stay faulted long enough to throw a code, but will disable the cruise when it blips... Again, I'm not completely positive the cruise system uses the tone rings to stay active...

Good luck!!

Cheers!!

 

I'm not sure why, but it's working again. After all the connections and grounds I took apart and cleaned I may have actually fixed it, or maybe it's just on the working phase of the intermittent cycle.
Anyway, I think it's time to close this thread. Thanks for all the help.
