Caterpillar GC40K:
Fault Code DTC 1111

I am working on a CAT GC40KS1 that keeps throwing a fault code and I am having trouble identifying it. DTC 1111 (According to my PSI Display) or DTC 1512 (Listed in some SRMs) The fault code description is "AUX analog pull-up 1 low Voltage".
I am trying to find any information that anyone may have regarding this fault. I have a basic idea of what an "analog pull-up" does but I can not find any corresponding information as to what analog sensors this particular fault is related to.
Thanks
