4wd service codes
We're traveling and have been having some odd issues with 4wd indicators. Truck is described in the signature line and has the electric transfer case (3 button) panel. I've been seeing intermittent "service 4wd" on the dic now for a few weeks. Later I noticed the 4x4 neutral indicator and service 4wd on. Codes were p1172, p1637 generator-L-terminal circuit, p0266, p0267, p0268, nd099, nd024, cleared codes, next morning 4x4 low indicator on with check engine light, codes p0500 speed sensor malf, p0700 tcm malf, drove 60 mi to yuma, cleared codes and all looked normal. next morning service 4wd indicator came on, no active codes but "not run codes" were p0540 and p0543, p1172, p1637, p0266, p0267, p0268, nd099. I was thinking about pulling the tcm fuse just in case but don't know what it is called in the fuse panel.
Don't want to get stuck on the road home as the are long lonely roads and it will still be really cold through Canada.
Any suggestions as to what part may be failing based on the codes I've listed?
What does the "codes not ran" on the Predator diagnostic screen mean?
Thanks
