I have a 2013 XLT. I enabled remote start with Forscan and a few other mods. The range of the remote start sucks but works, or should I say worked. Long story short. Got out of my truck after a short drive and the audio from Sirius and Bluetooth worked fine. Got back in the truck and noticed no audio from any source. Turned off truck and cranked it again, nothing. Searched google and saw someone with same issue, his solution was after he locked the truck and started the truck with remote start, audio was back. So I gave it a try, but remote start isn't working either. I can lock the truck with the fob and then hit the remote start button twice and it sounds like the doors lock again, the turn signal on the side mirrors blink twice and then after about 5 seconds the horn honks. Engine never starts. I am new to the forum and have tried to search this issue but have't found anything yet. Thanks for any help y'all can provide.

 

Hook up FORScan and see if you have and faults with the BCM. I had an issue where I lost all key fob functions with both keys and my Ford phone app wouldn't work either. I could manually open and start my truck. My fault was with Key Synchronization. I know it's not the same as your's but my point is the fault did not turn on the CEL.

here are the DTC’s I get from the Bodycm. When I run a self test for the bcm it says everything is fine though. Thanks

 

The first thing to check with that code is whether something is interfering with your key right on your keychain.

Maybe just reprogram your keys.

 

thanks. I cleared the DTC codes and ran it again and I don’t get the bcm codes anymore. Now just get a battery voltage warning. also, only have the key/fob and no other keys on a keychain
