The following is to be used as a guide on how to install ACC, FCW, Lane Assist, Auto High Beam headlights and rain-sensitive wipers in your 5th Gen Ram 1500, also known as the Advanced Safety Group. I’ve also included a guide at the end of this document on how to install blind spot monitoring. Obviously, I cannot guarantee this will work on your truck, but I am confident it will. I was able to install all these features on my 2019 Ram Lonestar which originally came with an 8.4" Non-Nav Unit with Dual Climate control. I believe this can be activated on any 5th Gen, but I’m literally the first person to have done this (that I am aware of) so it’s possible there are unknown variables that will prevent activation. This install is for those that have experience with AlphaOBD and assumes you are familiar with basic terms and procedures. It is not advised to do this as your first project, but you are free to do as you want. I believe this to be a mostly complete guide, but I wrote this from memory after 8 months working on this project so some things might have slipped through the cracks. Big thanks to all those involved along the way.

The purpose of this thread is not to debate "if it's worth it" or to discourage others from spending their money how they want. Everyone has different opinions on this. I took this project on as a personal challenge to see if it was even possible and with a larger goal in mind than just these stock features.

If your truck came factory equipped with FCW but not ACC, you need the following: (see attached file for additional information).

HCU: 68415320AA ACC w/Stop and Go - $265.55

ABS Module: 68436462AJ Adaptive Cruise Control w/Stop and Go], [Adaptive Cruise Control w/Stop and Go] After 06/06/2018 - $200.64

ACC Button - 68309592AD SWITCH. Speed Control. Right. = $57.05



Lane Keep for 2021 RAM

Requires:

Center Stack 68312620AG – $468.60

We can't thank you enough for getting this done and operational plus providing us with step-by-step instructions! I just ordered everything to make the swap from 8.4" to 12.1" uconnect and this will be the next thing on my list. Moreover, once, I fully upgrade my stereo in my truck I don't think I will be trading it in or selling it anytime soon! This options basically gives me most of the things I was missing from my JGC. Thus, makes my Big Horn worth keeping for a long time! Thanks again for all your hard work!

Holy moly. That is one slightly involved mod. Kudos to you for figuring this out and taking the plunge. Great write up!

Outstanding work on all of this. My truck is factory equipped with FCW and auto high beams using the DASM, so based on what I have gathered I should be able to just add the remaining parts and save a good bit not having to purchase a new DASM.

If that's the case you should be able to activate very easily... Interesting that they would activate the FCW from the factory but not the ACC or lanesense.

Based on my parts research, and conversation with Jimmy07, I’ll need the parts for the braking system as they are different based on their purpose. I’m guessing they are designed differently to modulate brakes smoothly vs full application with just the full speed collision system. The switches will be simple to swap in.

Typical of companies saving a few bucks here and there to get you to jump to the next trim level for certain features.

That would make sense. Probably the same system that stops the car with the reverse parking sensors is the same as the FCW. Either way, those are the cheapest components in the whole setup so you'll get a really nice upgrade for very little cost. Nice!

I am curious about your setup. Looks like we have the same truck options. does your truck have the camera that is in my picture?
I was told that this is not DASM that is needed for other advanced safety functions --- it is just for high beam.

You are correct on the camera. That is not the DASM. You would need to replace it.

As mentioned already, that’s not the DASM, it’s just the camera for the high beams. My truck is equipped with the full speed forward collision warning with emergency braking, but not the more advanced features. It utilizes the DASM for that system, along with the auto high beam function, and apparently it controls my standard cruise control as well.

To get the ACC and lane keep, I should in theory be able to utilize my current DASM and just add the HCU and ABS module along with the buttons. Since they are listed as different part numbers, one can guess that they are designed for either full brake application, as in my truck’s case, or the ability to modulate them smoothly for the ACC.

Now I am wondering if adding the radio bezel with the lane keep assist button and activating that feature in the BCM would enable that feature independent of the ACC, or if they are tied together in some way. Time for more reading.

interesting, so it looks like that for 2021 RAM includes DASM even though it does not have other safety features like ACC and such

This might be accurate - i think one of the new standard safety features (maybe starting in 2021) is Automatic Emergency Braking (AEB). If that's the case it would require the DASM.

I believe you can activate these separate of each other. When I was experimenting with Alpha on this project I tried enabling these separate. What happened is the menu on the dash would change from "ACC and Lanesense off" to "Lanesense off" or "ACC off" depending on what i had deactivated. I'd say attempt to activate the lanesense options in alpha obd and see what happens. It shouldn't have any other effect on your truck in theory.

It is listed as a standard feature on my window sticker, so I think you are correct that it is included now, at least on the Laramie.

Full–Speed Forward–Collision Warning Plus
Advanced Brake–Assist

I am trying to source a good part number for the center stack that includes lane assist now, but without a photo of the part along with the description it's a little tricky and I don't want to gamble on a $500+ part. Hoping I will have some luck searching dealers and find a truck with it and I can use the VIN to source the correct part number. I may mess with alfaobd and see what happens if I enable it.

That's my issue too on the center stack. Just trying to find the right one is a pain.

Do you know what part number abs module your truck currently has (use AlfaOBD to read the system status if needed)? If you have FCW+, I would think you already have the correct ABS and HCU, since they need to be able to interpret data from the DASM to automatically activate the brakes, which the standard abs module isn’t capable of.

Here is a vin of a Laramie with the 12" screen and the advanced safety group. Also has the tech package if anyone wanted to see how much the dash with the HUD opening is. 1C6RREJT4MN628940
