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

[DailyDriven]

I want to thank you all for all this accumulation of knowledge.

I do not own a Ram but a Gladiator. Yesterday, I was able to complete the installation of ACC on my Gladiator using some information from this thread.

One thing I wanted to add to this is that I learned during my installation process, I found that AlfaOBD could not "initialize" my used ABS unit or perform any of the sensor calibrations.

One thing it was able to do is, it deleted the old VIN. I do not know how it happened but it did.


I used Witech2.0 with J2534 cable to initialize the used ABS module and trained the DASM using my laptop and now I finally have a working ACC.



I ended up training it twice and each session took about 5 min. Used hotspot from the vehicle for the laptop to keep connection for Witech2.0.

Once the DASM calibration was done, it still had some codes including C2227 from DASM that I was able to clear by re-initializing the ABS module.



Thank you all for the inspiration and willingness to help!

I have both JScan and AlphaOBD. I could not get Alpha to initialize the new part. It turns out that it was in plant-mode and had to be disabled first - prior to initialization. In JScan that was easier to fix than Alpha. I also was able to do the FULL initialization using JScan over Alpha. it walked me through all three steps - static initialize - G (whatever) lat. Calibration - and clear Rolls info. No need to fuss with hacking Alpha to get to the Lat acceleration calibration.

When done, the vin was assigned. Cool.

BUT, like others, I have the EPB error and it hasn't gone away with cycling, etc.

I also have LKA and FCW errors, now, after installing the new steering wheel module and editing all settings. FUN.

I drove over 30 miles and am letting the truck sit with battery disconnected as others have mentioned doing for some miraculous, non-logical, fingers-crossed fix. Maybe it's some special voodoo and I'll be lucky.

I'll post back as it progresses or digresses.

Congrats @DailyDriven, that is awesome. I feel like I need a better software tool myself - especially one to initialize a new RF Hub.

Here is the update: after letting it sit overnight with the battery disconnected. I plugged it back in, started up. The only error left was the Electronic Parking Brake not being initialized (which is BS). I guess the Voodoo really does work - for the most part. (I can't believe the memory cache can survive as long as it did. Must be some hell-a long-life capacitors in there.)

I took it for a drive and got to experience ACC for the first time in my life. That was so friggin cool!!!

Now, If I can just get rid of the Parking brake light, I'll be golden.

Computers are weird, that's for sure. Who knows why the whole "letting it stew" method seems to be working, all we know is that it does.

As far as the parking brake one, did you try cycling it a few times? If I'm not mistaken I had to run it on and off I couple times for it to adjust itself and it worked fine with no errors. I feel like there might be a button for it in Alfa but I'm not positive and would have to drag my laptop out to the truck to figure that out for sure. I don't really want to do that as it's my main computer and is a bit of a pain to deal with the multitude of cables I have plugged into it.

One thing with the ACC I've noticed, it's a bit rough on the brakes when people are slowing down significantly, like SoCal traffic I have to deal with. It's also pretty rough in slow moving traffic, really wants to get up and go, and when it figures out it can't it hits the brakes pretty hard. It's not nearly as smooth as I was hoping it would be, but for dealing with regular traffic flow it's pretty darn good. Better than my Tacoma was, at least. At any rate, be cognizant of that until you start learning all the quirks, doesn't take long to get used to it and train yourself how to best use the system.

Can anyone clarify what parts I need if I have the Full Speed Forward Collision Warning Plus and Auto High Beam features?

It's all in the first and second posts. Mainly the 2nd one.

I can now confirm that a used DASM can be used for this project. I successfully calibrated 2 used ones in my truck this weekend.
When you have the dealership do the calibration, tell the tech to perform the following on the DASM:
1) Perform the enter plant mode routine
2) Clear all DTCs. This will get rid of the vehicle configuration mismatch, and allow the calibration to be run.

Then they can run the calibration like they normally would:

How many steps does the ACC take am having problems with it getting past 40 and it takes almost 20 minutes to even get there just driving in town and highway. 2022 ram 1500 with a lift kit and after market tyres ride height is about 1015mm

What do you mean by steps? Are you saying that you can't set ACC past 40 MPH? Can you add more detail like what are you doing from start to finish?

 

[Kenmbithi]

Thanks for reply, am trying to calibrate the DASM, the forward facing camera is getting to 100% easy but the adaptive cruise control step its taking very long to calibrate. And the radar adjustment is done as per witech2 instructions.

So I have been kicking around the idea of adding ACC, what are the ramifications of using an HCU and ABS Module from a salvage yard? Are there additional steps needs since it is a used part married to another vehicle?

I just did one with a used abs/hcu a couple days ago, it’s no different than going with new parts.

I am struggling in a major way to do the Alpha OBD changes/set up. I have a 2022 Rebel and the only items I needed to add were ABS,HCU and the steering wheel button. Which I have done all of these. I have gotten the ACC option to pop up but it says (ACC Unavailable Service Required). Other dash lights/messages include AEB Unavailable Service Required, Service Antilock Brake System, Service Electronic Stability Control, Service Trailer Brake.


Has anyone done the Alpha changes using the Windows version not the Android app? I have been trying to follow the original instruction plus some of the additional write ups and run into multiple issues. The only fault code I get in Alpha is C2206 (Vehicle Configuration Mismatch). I have Reset Vin Values and get ????? in the VIN location when I run the System ID. If I then do a Static ECU Initialization it will run successfully but then if I go check the VIN in the System ID it is back to showing my VIN. If I run all of the steps after this as described in the write up, I can never get the Longitudinal Acceleration Sensor Calibration to work. (If I try connecting to the 2013+ PowerNet as others have mentioned doing, it always reconnects me to the 2019+ version).

I am obviously doing something wrong and would greatly appreciate any help. Main questions at the moment are, 1) Is there more to the process if using the PC version of Alpha vs the Android version? 2)How do I get rid of the C2206 fault?

Did you get the ABS initialization? That's probably were you are failing. You shouldn't have an issue between versions of AlfaOBD.

Thanks for replying. I have attempted to run a ABS Initialization but run into problems. The steps say to do the following
-Run Static ECU Initialization - I can successfully complete.
-Longitudinal Acceleration Sensor Calibration - It Fails
-If the car is equipped with ESC: clear stored DTC, cycle ignition. - I have done this and also tried skipping it.
-Run Clearing Rolls Information - I can successfully complete.

After doing this I am still getting all of the same messages. Is there a next step I am supposed to take following the Run Clearing Rolls?


Thanks again for your help!

If you can't successfully initialize it, then that is your issue. If you can't do it, you need to find someone (dealer) to do it.

When you go through all the ABS initialization steps are you supposed to have a "Start" button at the bottom to click? That is always unhighlighted grey where you can't click it at any point.

Is there any other steps that can be taken to clear some of the lights on the dash prior to taking it to a dealer?

 

[Zekster33]

I've been able to run all of the procedures successfully but still am getting two error codes C2206 and C10D0. I let the truck sit over night with the battery unhooked and tried running the test again today. The VIN is now repopulated in the ID but I no linger have the C2206 code which doesn't make any sense. The C10D0 is still coming up and I don't know how to clear it.

I can only get the ABS Initialization to have a filled in Start button randomly and usually it's when I crank the truck but if I click the start button nothing happens. Any ideas why that might be?

For the C10D0 fault, you’ll need to run the EPB assembly check routine in the abs module.

 

[Zekster33]

Thank you, I found the instruction on that routine and was able to clear the code. So now I have no codes showing but even when I run through the ABS Initialization procedure after Clearing Rolls Information and I go back to the ABS Int and the start button is active, I can click it but nothing happens. What could cause this?

Also when I do the Clearing Rolls Information are the messages supposed to be as followed?
Test Status:
-In-Plant Mode Status - No
-VIN Learning Flag - Yes
-Tire Size Programmed - Yes
Session Still Running - No

The actual abs initialization page is not a procedure that you press start on. It is just a page that gives you a list of what procedures need to be performed.
Clearing rolls information is last step of the initialization, and once that passed, you’re done.

Please tell me if I got this right...
All I need is the ACC Switch if I have a 2021 RAM with factory installed DASM and 12" screen? See quote below.
My VIN WBAGV2C02LCD73566


"Lane assist, ACC, Parking assist, Pedestrian Emergency Brake for 2021 Laramie with 12”
screen and FCW (DASM factory installed), this list can be used for most 5th Gen
RAM1500 with DASM factory installed, except TRX ( NEED ONLY 68309592AD for ACC)"

I'm not sure where that quote comes from. You quoted the post that tells you want you need. Second post in this thread. And why did you post twice about it? You started another thread and also posted in here. I'd suggest deleting the other one.

But I have no idea what trim you have done you didn't post that.
