Hey guys! First post, new here, I have a 2012 F150 extended cab long bed and have been having some issues with codes and such and havent been able to find much on it. Lately, my service advancetrak note comes up on my dash along with the light and leaves me with no turn signals unless I hold the turn signal switch down in the direction I want to turn, it comes on and it might stay on for 5 minutes or an hour or so and then it shuts off and wont give me fits for a couple weeks to a couple months. and everything goes back to normal, same thing is happening with tire sensor monitor. getting a fault code for that one too but also comes on and goes away. everytime im on my way to get the code read at the dealer it seems to shut off and they cant tell me anything, ironic right? Thanks Guys, hope I posted this in the right place.

 

Already a big long thread on it:
