Does anyone know anything about this code? 16188051 pcm $EE

Tunerpro $EE-16188051-V3.2 xdf lists it as system voltage high.
The section here for this PCM doesn't even show a code 76
Google search comes up with Digital EGR solenoid #2 circuit error

I have checked voltage and it's under 14 at the battery as well as the fuse box. I don't have a clue what to do if it's something with the egr.

Also, this is a transplant into a 87 Truck with a painless harness. I have turned off a bunch of error codes in the tune but there is not one for 76(unless I missed it).
