I have a 2021 Silverado 3500 HD Diesel LTZ and the trailering app won't turn on after the truck had to be jumpstarted. All other apps and functionality of the Infotainment System seems to work ok. Any ideas/suggestions? Thanks!

The batteries on my 2021 Silverado 3500 Diesel LTZ DRW were inadvertently drained fully down because I left a wireless camera monitor plugged into the cigarette lighter for two months while in storage. After jumping and recharging the batteries there are two electronic issues that have occurred: the Trailering App will not turn on in the Infotainment Screen, with or without the trailer connected, and 5 of the 6 tires on the truck are not reading pressure correctly on the dash screen. Everything else seems to be ok. How do I fix this? Thanks!

The batteries died on my 2021 Silverado 3500 LTZ because I left a wireless camera monitor plugged into the cigarette lighter while the vehicle was in storage for two months. After jumping and recharging the batteries I have a problem with two electronic functions: the Trailering App will not turn on (with or without the trailer connected) and the tire pressures on the truck are not reading correctly on the dash display for 5 of the 6 tires. Help?
