It seems like no one ever resolves these threads. My 2016 1500 5.7 recently threw the P1DCA-00 code. At first there were no symptoms. The past couple of days it has also caused a battery drain. Dies after a day or over night. Originally the first issue I noticed was one day I started the truck and the tire pressure light would just randomly go on and off also chiming as well. I have a tire machine, autel ts508, sensors are less than 2 years old. It's not the sensors. There was also no TPMS related code. So I went in alfaobd and disabled the tpms system to try and narrow it down. This stopped the flashing and chiming. Second time driving it threw the P1DCA park sense circuit open code which it continues to throw(however it does say intermittent). I don't have parking sensors on this express package so I'm assuming it's something related to the rf hub not communicating to the TCM that it's in park? Not parking sensor related? Alternator puts out mid 14V's charging and the battery tests good before you ask. I'm going to test for a draw on all the fuses in the TIPM after work today to try and narrow it down. I have another 10k miles on a drivetrain warranty on the truck but I'm sure the dealer will claim this is not covered if I drop it off so I'm doing my best to figure it out. Not currently but I did also have a P1DDE-00 code pop up. Truck did have an aftermarket remote start which is tied into the canbus which I temporarily removed to also eliminate that as the issue.
