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

The black box flight recorder was invented by Australian scientist David Warren in the mid-1950s. While initially met with indifference in Australia, his invention gained international recognition, particularly in the UK, and is now a mandatory piece of safety equipment on all commercial aircraft.
