How to: Add Adaptive Cruise Control, Lane assist, FCW & Auto Hi-beam to Ram 1500

[xJudge21x]

Success adding the Lane Keep and Pedestrian Braking (although haven't tested that out yet..maybe a job to the 17 year old!! Have him walk in front of me..lol..just a joke!)

Ordered the ACC Switch HCU and ABS Module, so once they get here I'll start working that project! Thanks so much to this whole community. @vincentw56, @MayhemMOORE, @tdb0021, and most recently @gmenarvino for all your trial and errors on this. And @Jimmy07 for all the expert advice on all things parts and Alpha and everything!!!

Just changed screen for the three buttons one, all is working perfect, I will work on Park assist in August when I'm back from a big trip.

Thank you all!

Ps: @Jimmy07 about the new upcoming feature for keeping the car in the center (coming in Gran cherokee) once fca update the firmware (in the future) will this option be available for us?

Are you talking about lanesense? Did you activate that in the computer? Mine works by nudging me back over when I get close to the lines.

Yes, the lanesense "center line" is a new feature not yet released, what you and me have is exactly what you described but, keep center will be same/similar as the basic tesla autopilot , keeping the car/truck always in the middle itself.
If you activate that now I believe it won't work.

I’m assuming you’re talking about active driver assist with lane centering on the grand Cherokee L? Retrofitting that into a DT isn’t going to happen. It’s using night vision camera modules, and more importantly, it’s running on a faster canbus- FD.

Yes, I was referring to active driver assist.
Thank you

You can use Comma.AI to get that.

Yes I will also look at that...

Great information! I am curious about one thing. I have a new 2021 RAM 1500 Bighorn with the Level 1 Safety Group, which gives me the DASM already, and has pedestrian emergency braking, advanced brake assist, full speed forward collision warning plus, and lane keep assist.

Since I have the DASM already, with lane keep, emergency braking, etc. would I need the ABS module and HCU in order to get ACC working? Or would it just be the steering wheel button and AlphaODB/hardware?

I believe that would be all you need and then enable it with AlfaODB. You could try it since it would cost about $100. If it doesn't, then you'd probably need the HCU and Abs.

Easiest way to find out is to have a dealer look up the parts installed on your truck via your VIN. Even with the DASM and FCW+ with AEB, my Laramie still doesn’t have the required abs/HCU for ACC to work.

Ditto here. As @MayhemMOORE has found, most of us with 2021s have to get the HCU and ABS, so far the only one that was able to do the switch only was @gmenarvino and he has a TRX, so I'm guessing that had something to do with it, maybe TRXs are just built that way...

Also can confirm that only the switch swap + enabling in the BCM is necessary on TRX. Forgot to post update on this from a while back.

How difficult is the ABS/HCU install for someone who isn’t super experienced working on cars? Too much for a first mod?

when you read the step by step pdf provided by @tdb0021 how you feel about it? The PDF is the post number one of this thread.

Removing and installing is not too bad. Because you are removing brakes lines, you will need to bleed the brakes. So it really depends on how comfortable you are with that. None of it is super difficult.

The ABS module is just 3 screws and a connector. It’s the HCU that some people may not feel comfortable messing with, since as others have said, it involves bleeding the brakes.

I have a question. I have a 2021 Rebel with a DASM and the FCW. Is adding Auto High Beams a simple AlphaOBD change?
