Hey all, you have all been able to help me in the past and I'm calling on you once more. Twice in the past month the wife has called to report that after starting her truck in the morning the Brake Light VSC OFF VSC Trac ABS light are all on (no CEL) with a high pitched buzzing. It all stays on for a few miles then they ALL go off. Doesn't happen every morning either. While the lights are on and buzzing wife reports that the truck runs fine. Breaks work, no engine power issues. I've driven it a few times to and from work and have not been able to get it to do it for me.

I've read a few things on it here already and most folks seem to have the lights stay on, or are just interested in bypassing the VSC all together so I havent found anything that is the same as what she is experiencing. Anyone have any ideas on what I should check first?

I already told her to make sure he gas cap is tight next time she gets in it this afternoon, and i'm going to have her check the Center Diff Locking Button to make sure its not engaged. Thanks all.

Update, I was able to pull an ABS code by jumping the E1 to Tc on the "DIAGNOSTICS" connector that's on the drivers side of the engine. It blinked 5 times then two times then long pause..so 52...have not been able to figure out what that means yet, any help would be appreciated. Thanks again.
