Adding adaptive cruise

[wbama387]

I purchased a used DASM 04672894AB. Plugged it in but I guess I need to take it to the dealer to get my vin programmed in it. Does anyone know if using Alphaobd and turning on the LKA options brings up the LKA light on the dash without having the correct hardware installed yet? Before I go get this DASM programmed I want to make sure I am on the right path as I would expect to have the LKA light on the dash at this point.

Well new DASM 04672894AB did not get LKA working. I was able to get it into plant mode to recognize my truck and then calibrate it with no issues. I know it’s working as ACC is working. By any chance does anyone have LKA functioning and could send me a backup file of their truck with alphaobd so I can see if maybe something in my BCM is not set correctly? Thanks.

Have the issues toward the end of this thread been solved? I'm looking to do ACC, LKA and a DRVM in my '22 2500 Limited Longhorn diesel and want to make sure I have better than a 50% chance of success before I end up with $2600 worth of paperweights.

its been a minute since I’ve been on, someone messaged me direct which recalled my attention to the thread. I just spent the last hour reading up and I’m feeling bad for all you guys towards the end here! It has been a bit since I completed mine but I was completely successful and I use the Comma.ai on my truck all the time. It was certainly worth my effort and $. Here is what I had and where I went:

2022 Laramie Hemi
Steering overlay was factory

I replaced:
- the entire 12” display to add the LKA button.
-Windshield
-DASM (new 2022 model specific)
-rear view mirror (had auto beams from factory and wouldn’t fit new windshield)
-wiring harness
-steering wheel controls
-The o ly Alph settings I made were those identified by Jimmy07 prior to my post saying it worked…somewhere in the 20s range I think.
-I did not involve a dealer at any point. I bought the tools and a WiTech subscription. I had errors on the dash prior to Cali but no idea what they were. The calibration was straight forward in WiTech, once completed everything worked as expected.

Appreciate the update, same year and almost the same trim gives me some confidence to make this upgrade to my own machine. Which tools did you need to buy to complete the upgrade yourself? FCA dealers in my area still give me nightmares after the issues I had with them on my wrangler.
