2015 PW TPMS light followed by every malfunction light in the book

[Hawk6815]

Hello all,

I’ve got a 2015 2500 SCREW Cab that while driving down the highway it tripped the TPMS caution with a chime then every othe malfunction light right after including an error message on the Uconnect about reprogram phone.

After an ignition cycle, all faults but the MIL light and traction control light were gone. Another short drive and even those were gone. Pulling the codes shows just about every module in the truck stopped talking to one another.

Any ideas or experience with this?

Try disconnecting the battery, both wires, touch the wires together, reconnect the battery negative last.

My 15 that I got last December has some pretty strange electrical Gremlins. I've had it reset itself like the battery was disconnected several times. I know because certain settings will default back. I've also had the truck just completely shut down while sitting in it. Not a single light anywhere. With all that I did eventually find that the positive terminal was loose enough I could pull it off so I'm hoping that was the issue as I haven't had an occurrence since, about 3 weeks. I'd check all your grounds also and even disconnect each and clean up the contract area. I think these trucks r very sensitive to voltage drops. Do ur headlights ever dim slightly?
