Yesterday and today I noticed that every once in a while my Check Gauges light would flash on for just 1/4 of a second and go back off again. My truck has never done this before. Anyone have any idea what might be causing it?

 

I think there is a TSB on that. I had mine reflashed early last year for it and it has not happened since. It is just a glich in the software.

 

Yep same here nothin to worry about I think the TSb had only to do with the trucks with the infinity stereo.

 

I had a positive battery cable that wasn't tightened down enough cause the check gauge light to come on periodically.

 

I'll check my battery cables, but if it's just a glitch and doesn't mean anything then I'll live with it. My truck has been perfect since the day I got it. I have no intention of letting the dealership mess it up.
