Installed the mopar power running board kit on my 21 Laramie this morning and everything went as planned and the boards functioned as anticipated UNTIL I started driving down the road both side would extend and retract about every 10 seconds. Is that Normal behavior if you haven’t had the sales code flashed to the u connect?

I haven’t heard of that before. Sounds like you may have a wire shorting to ground intermittently.

I put mine in a 21 Big Horn two days ago and mine have not done that.

It’s really weird. Only does it above 15 mph and when the speed drops below 15 mph it stops and the steps will immediately retract and not extend if below 15mph

My guess is you should re-check your wiring. Recall something in a way earlier thread similar what you are seeing and either a connection wasn't seated right or misplaced wiring. If you are sure you have it right, it may be a bad module.

I’m at a loss. Checked all the wiring 3 times, moved the ground and changed where it plugs into the white board in the truck. Only thing left is the control board.

May not be a bad idea to bring it in to a trusted dealer service center and have them flash the sales code in your uconnect so you can get full functionality. At the same time they can take a look at your wiring to see if anything looks off.

Took it to the dealer and they flashed the system and work fine now.
