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

[mahnkal]

The two main settings you need to change for ACC are disabling cruise control, and changing the type of ACC to ACC with stop and go. Neither of those settings are present in adaptations in JScan.
The developer does frequent updates, so message him and tell him to add “VehConfig 2: Cruise Control Present”, and “VehConfig 7: Type of adaptive Cruise Control (ACC) system present” for the Ram trucks. He’ll know what these mean because he uses the same software that alfaobd uses to develop their apps. He should either give you a test version that includes those settings, or release an update that includes them.

Awesome information! I messaged him, so we will see what happens! thank you!!

I have the parking sensors that slam on the brakes if too close - any chance that my ABS/HCU are the correct parts? I do NOT have the DASM. 2021 Ram Bighorn eTorque Hemi.

No, not at all. That's a completely different system.

I have DASM and everything minus the ACC, and to my knowledge I still need the ABS and HCU modules to get ACC. 2021 big horn eco diesel.

Don't know if this helps or just confuses...

Here is what I have for the parts for a 2021 RAM that already has DASM and FCW+ are below:

so if you only want lane keep assist and no acc do you still need the hcu and abs module

Don't know. No one has tried it yet. Let us know how it turns out.

I did lane keep assist first, then ACC with hcu and abs.

 

[bwade1]

so its not needed for lane assist to work

This is unbelievable 57 pages already, same questions over and over again! Why not to use search button, You will find all replies on Your questions. Post #125

This post doesn’t answer the question. Can you add lane assist without adding acc and if so are the abs parts still needed. I was looking at adding only lane assist at this time. I see nothing mentioned about only adding this function

I bought my BH with lane keep assist and no ACC from the dealer. So, I think it's possible.
I wanted ACC and had to add the different ABS PARTS.LKA doesn't require them.

thank you . do you know what changes would need to be made with jscan do do this

I dont have the answer other than I have found searching in JScan for similar language from AlfaODB has worked well for me. If you do use JSCAN to program this can you post up on the JScan thread? Trying to get that to be a good resource for those of us who use it.

I have a 2024 Bighorn with level one safety, so DASM, FCW, lane keep assist, etc.

Anyways, today I installed the HCU and ABS controller, manual brake bleed, Alfa obd brake bleed, cleared codes etc.

I went in to the body computer setting and changed all of them according to the pdf guide however I am still getting three lights on dash, the acc/cruise service req, parking brake and fcw off. Anyways, I’ve triple checked the setting and reset the ECU.

A few months ago I installed the ACC button on the steering wheel and got ACC to show up and work up to the point where it needed to slow down, then it errored out because of the wrong HCU.

But this time I cannot get it to clear the errors. Do you think because the parking break error light is on, it’s causing the others to not work. I’ve tried clearing the parking brake light with no success.

Any suggestions are appreciated!

Trip to the dealer to initialize the ABS. At least that's why others have had to do.

 

[cwatts10]

Yeah I may end up taking it to the dealer. I just wonder what to tell them? I guess just ask if they can clear these lights?

I’ve attached a pic of what I’m getting on my dash now.

I have the same setup, is this going to be mandatory for all of these installs, and can just the dealer do it or will my mechanic be able to?

Some people have been able to do it fine. But what I found out, is when you can't the dealer can. Also, not 100% sure if your mechanic can or not. Just depends if they have the correct equipment. I worked with someone on it who's mechanic couldn't, but his dealer could.

Just tell him you replace the HCU and ABS unit and you need to have it initialized. You don't really need to tell them much more than that.

Going to the dealer tomorrow to see what they can do. Hopefully they don’t ask too many questions…
