P0702 code and blown DTCM fuse

[DLGonzo]

Correcting my post from before since I mis identified the fuse. Stuck in limp mode and have yet to find any damaged electrical components

Was pulling a small trailer when abs and traction lights come on along with check engine. Goes into limp mode. All I can find is a blown DTCM fuse and blows every other fuse I put in when ignition on.

That fuse also feeds the front axle disconnect and the xfer
case control module. Would be worth disconnecting those and see which blows the fuse when plugged back in.

Yup. Unplugged the disconnect and the fuse doesn’t blow and limp mode’s gone. Got 3 months left on warranty so hope it’s covered.

Yay! Glad you found it!
