So I was driving home yesterday with the ol cruise set and the truck kinds felt like it lost power then resumed. Then it did it again and the cruise control shut off and I got the ol 5 blink then the cruise could not be turned on. It will turn on only after the truck has been shut off. I pulled up the code here is a video:



To me this looks like error code 12 which my FSM says is overcurrent (short) in magnet clutch circuit or open in magnet clutch circuit for 0.8 sec.
Now I have no idea what that means or where to start troubleshooting the issue. I did lube up the cruise control module and moved it back and forth with my hand. I disconnected the electrical connector and cleaned the contacts. I also removed the speed sensor on the transfer case and cleaned it and the contacts\connector.. Looked for any frayed wires and could not see anything. Do any of you have any suggestions on what to focus on? Is the ABS light supposed to be blinking when checking for error codes? When I took it for a test drive the cruise worked at around 35mph . i then canceled it and tried again at around 45 mph and it failed.. I don't use it much but I hate it when things don't work like they should on my ol friend.. Thanks for any tips..
 
I have the same issue but have yet to solve (though have not tested currents and frankly that's beyond my capabilities as the currently stand!)
 
So I have had some success here.. I went and looked at the slack in the CC cable and there was quite a bit. I was able to adjust it out to make the cable tighter. I also disconnected the cable from the cc actuator and cycled the top and bottom levers by hand several times. So far my cc is now working.. I think it is the slack in the cable that caused the problems. How does your slack look?
