Went out of town this past week and had the truck set off the alarm with no one around. Then the driver's door handle decided not to unlock when you grabbed it, but the passenger side still worked. Truck ran great and did not notice anything else not working. Got home and plugged in Forscan and had a bunch of DTC. Reset them all and still had this one that would not go away. Never had it before. If I turn off the truck and go away for a bit and then come back and check Forscan, I get DTC in TCU and HCM. But if I reset the DTC, the one in the HCM will go away. VCU one stays. Going to wait a few days and see if anything else pops up again. Any idea on what is causing it and/or how to fix?
