Cruise control

[Runaround]

I’ve got a 2018 Cummins powered truck. My cruise will not turn on. This happened about a month ago but after a day or two it started working again but this time it hasn’t worked in about a week. The fuse is good. Any ideas?

Check for DTCs with a good scanner.

AFAIK, any outstanding DTCs will disable cc. Does your remote start still work OK?

Pretty common topic on this era truck. I have the same problem on my '16 as the cruise on/off switch on the steering wheel won't always turn on the cruise. Very erratic and smacking the back of the steering wheel does seem to help. It's either a bad switch, loose connections, or possibly the clock spring (swivel connection that lets all the wires go through the turning steering wheel). In any case, pretty sure it's something within the steering wheel area where the switch is. I need to pull mine apart and look at it.

I have seen a post or video somewhere where someone found a broken wire on the small yellow clockspring connector. It has 8 or 10 positions, if I'm not mistaken.




They were able to repair it by extracting the crimp lug from the connector housing and soldering the broken wire back on where it came from.

AFAIK, that yellow connector interfaces all of the steering wheel buttons.

I would start by checking for DTCs before disassembling the steering wheel but, there are lots of great videos on YouTube for changing or repairing the Ram clocksprings.

My remote start still works.
I’m pretty sure the problem is the switch itself. Someone on another forum told me to push and hold the on button and the resume button at the same time and then it came on.
Now I have to find out how to change the switch.

There was a recall for the '16's for the clockspring. Mine was done under the recall. Was yours done?

When I bought mine last year I was told that there was no open recalls.

When I bought my truck last year I was told that there was no open recalls on it. I don’t know which ones if any have been done though.

Try holding the up and down buttons for the cruise control for about 30 seconds. It resets something in the computer.

'16 Tradesman here. Mine does this every once in a while, moreso in colder weather. Not pushing any buttons, just the left and right rib in the center, I push into the steering wheel with both thumbs. Evidently the switch will come unseated a bit? This has worked every time I've done it. Not worth a new switch to me, first vehicle I've had with cruise in over 20 years.

My '14 , and many others have a simple issue with the cruise. Its the contacts on the switch. Rarely happens, but when it does seems a good slap on top of the steering wheel over the switch, and viola! OR, tear apart your steering column, and get to the switch. Clean the contacts, push the plug back on firmly, and start putting your interior back together.

I went through this. In the end I replaced the steer wheel buttons, brake switch, clock spring.. same issue still. Mine turned out to me the steering wheel harness that goes from the clock spring to the buttons, the white connector that plugs into the clock spring (or as Mopar calls it steering angle sensor) there's a little plastic piece that crimps onto the wire, mine broke between the crimp thingy and the pin crimps...

I'd check that harness first, it's 3 clips to get the airbag off, then you have access. Here in Canada it's $200 dealer part, I got one from a wrong year Caliber and spliced in the heated steering wheel wiring and **** $10 fix for what had cost me $800 in other parts that didn't fix it.

Dirty switch is my guess but I was a Ford mechanic. Get compressed air to possibly blow it out.

I was able to get it working by pushing the on button and the set buttons at the same time. This was for my 2019 classic.

While pushing the buttons in a certain sequence, or a certain combination of buttons, often makes it work it is not "resetting" the computer or anything like that. Whatever they are doing, including smacking the back of the steering wheel, is all basically doing the same thing. That is jostling the switch or wires so whatever is loose or worn out is now making contact again.
