This message appeared today while driving without a trailer or camper being towed. Any suggestions on possible problems to check before taking to dealer? 2012 Chevy Duramaz 2500 Thanks,

Truck was covered with snow and ice for a few days so hope that is the cause. Has warmed up and sunny today with another round of snow and ice tonight! Spraying with wd40 hurt anything? Don't want a problem when need to tow in a couple of months Thanks
