Have a 2012 Silverado Z71 with 28k on it. Everything was working fine until yesterday and I noticed my remote entry fob no longer worked. I tried my secondary fob and same thing. Batteries are good in both fobs. I manually unlocked the doors and got it but once I started the truck I notices the TPS was not working either. The warning light was on but tire pressures were registering with proper tire pressures so no reason for it to be on. Later that night I checked the fobs again and still not working and TPS was on but this time did not register tire pressures. Got in the truck later and the TPS was off and when I got home the fobs would lock and unlock the door. Now today it is back to not working. The only thing that I have changed was I activated XM/Sirius radio the night before but would not figure that would cause an issue.


Update...
I cycled the ignition switch from off to on 3 times and the TPS alert went off and the key fobs are working again. Very odd to say the least.

 

I've had this happen on my Grandparents 2015 Equinox and on a 2013 Grand Caravan recently.

Idk what it is

 

An issue with the body control module or RCDLR
