TPMS & Radio gremlins

My 2013 F350 CC Lariat with 16,500 miles has developed a TPMS problem. Tire pressures are at factory specs, checked regularly and rotated at 5000 miles. I have not had any issues until now. The alarm went off a few weeks back as I was driving. I checked the TPs and they were good. The truck sat over night and in the morning I went to work no TPMS alarm. Went like that for a few days then an alarm. TPs still good. It has been going off intermittently now and it seems like when it is cool it won't go off. I tried the learning procedure by the owners manual and I can't get past the first tire. I bought a Ford TPMS training device and that won't work either. I went to work Yesterday morning no alarm I was driving along and turned on my radio and the horn beeped and a message came up LEARNING PROCEDURE FAILED TRY AGAIN, now my radio won't work. GPS, Climate, and Phone all work on the touch screen, no radio. Anybody have this happen?

The TPMS tool is of no use for the SD's. Maybe you can sell it to someone. The TPMS is probably not related to the radio issue. There have been cases of the TPMS acting strangely due to cellphone chargers or some other device that might have a harmonic of the TPMS frequency. Try removing any chargers that use 12v and go get a cheap 120vac charger from wal mart for like $8.00.

The radio issue is strange for sure. Are you saying the radio does not turn on or it is on but no sound? By change have you tried disconnecting the battery cable for a few minutes?
Just saying what has been reported that the cellphone chargers have been known to interfere with the TPMS and give false warnings. Do a search on the net about it. Or on this and other 6.7 websites.
