Switching light electric to heavy electric setting

[labren]

2014 Ram 3500 6.7 Cummins. So far I am unable to get the controller to stay in the heavy electric setting, it quickly jumps back to the light electric setting. I wonder if any of you have experienced that or have any ideas what it could be?

Here is another good video explaining the brake controller and also the two different modes for the exhaust brake. Watch it to the end. The do better camera work towards the end actually showing how to change settings.

I'm assuming you are going through all the steps but if not watch this to check yourself.

Last winter I was in the shop, and they upgraded a lot of software, including the trailer brake controller.

Perhaps that would help?

Since I reluctantly migrated from a '97 12V CTD to an '07 24V CTD a couple of years ago, I have no idea what you're talking about, but hope to read more about this, what this is, and a solution to your question.
