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

"Akeem in Guyana needed help with a steering sensor which isn't functioning properly. 'What can I check?' he asks. Martin from Quebec has provided the wiring diagram and suggests this is where the problem lies."

Fact of the week
In March 2002, identical twins in Finland died on the same day in similar accidents within hours of each other. A 70-year-old man was killed by a truck while cycling; hours later, his twin brother was killed by a truck on the same road, about a mile away, before the family had been informed of the first accident.
