I spend the last few weeks or so working with member Iggy F-150 on different parts & firmware flashing and I'm sad to report that a normal (non-ACC) ABS & non-ACC IPMA cannot be firmware flashed to the ACC version and function correctly for purposes of this stop & go ACC mod.
I sent Iggy F-150 three different IPMAs & a 2018 & 2019 ABS module for these experiments and he spent the better part of all weekend working with FORScan, IDS, and swapping parts onto his truck so everyone owes him a lot of gratitude for that
I can get only 2019 ABS & 2019 IPMA (both ACC versions) from my cluster supplier but FORScan cannot calibrate the 2019 IPMA yet apparently but I'll talk with the FORScan developer about that and hopefully get that added in a future release. IDS is definitely needed for any new ABS module but the jury is still out on whether a used 2018 ABS (ACC version) would work without IDS if anyone can find one from a salvage yard/eBay. Also, IDS will not run a PMI (programmable module installation) on a 2019 ABS installed into a 2018 truck.
Don't have an F150 yet but looking to get one with the newer ACC system.
I'm new to the forums and may be missing it but can somebody clarify if it's already possible to add the 2018 version of ACC (w/ stop & go) to a pre 2018 model F150?
What are my used truck purchasing options if i want this eventually? (because 2018 lariats with stop and go ACC already installed are super hard to find)
Just wanted to give the group an update on the ABS ECU situation on the 2018 ACC with Stop and Go. I've gotten mixed part numbers in reference to P5SVO's post. I've been informed that part JL3Z-2C215-D has been replaced by JL3Z-2C215-F. Then I had another Ford parts place tell me that based off part JL3Z-2C215-Dthe replacement ECU "only"could be purchased separately.The ECU alone part# I was given: JL3Z-2C219-C. We will see as I purchased just the ECU alone vs the whole assembly which includes the HCU. Based off my build date I found another KIng Ranch built a month later than mine with factory ACC and based off its Vin it was confirmed thru Ford parts having JL3Z-2C219-C for the ECU. I should know mid day Saturday after the dealer installs it and sets it up using IDS. The part lists for a little over $500 but if you order online you can get it for around $335. I was in a crunch to wrap this up by next week due to having to go out of town for a family Summer Vacation. I will repost late Saturday or Sunday hopefully having 100% ACC W/Stop and Go. If any one has thoughts I'd appreciate it being I've come this far and so close to completing this project.
ECU for build dates after 2/26/18.
Just wanted to give a short update on this project. I left for summer vacation but before I did my local dealer would not swap the ABS ECU as they told me they would so I had to look for a shop that would once I returned from vacation. I'm back on this project and dropped my truck off this morning for them to swap my ABS ECU and program it using IDS and preform the PMI & IVD procedure as called for. When I got the truck back I had 3 cluster messages that Livnitup help me get rid of.
1. Park brake limited function service required
2. Normal cruise active adaptive braking off
3. Pre-Collision assist not available
I had to run the ABS Apply & Release Calibration via Forscan to clear these messages. Then I took the truck for a road test. At first the engine was running high as if braking was being applied holding it back. It did slow down when I got close to the vehicle in front of me. After that it would not stay in adaptive cruise mode. In other words if you set adaptive cruise it will only work until it has to slow down. After it brakes and slows that's it. If you hit resume a cluster message appears adaptive cruise not available and will not slow down or speed up until you cycle the ignition again? I reported this to Livnitup and hopefully he can help find a solution to this problem. I will post again as we know more. Thought I would share for others who are adding ACC as well.

Make sure you have your IPMA wheel well measurements correct. Have you checked for codes? Have you rechecked your settings? When it stops working do you come to a stop?
Yes the wheel measurements are correct. I used the same number as my old IPMA. The truck will slow down but it made me nervous when it was about to make a complete stop because the vehicle in front of me was almost stopped and I was going almost 35! Little nervous so when I got closer I applied the brake but I believe it would have stopped. After that one time you have to cycle the ignition if you want to use adaptive cruise again or you get a cluster message adaptive cruise not avaliable.
Got bad news for you, that part number is for the HCU only, not the ABS module that you actually need. The ABS module alone is NOT available separately. If you can find one separately please let me, and everyone else, know.

So here's what I found with the ACC. It works great if you are following someone already and are coming up to a stop sign/red light, but if it hasn't locked on before that it'll stop you but it'll be an abrupt stop. As for the wheel well measurements, it wouldn't hurt to check them against the values that are currently entered, but it'll only help accuracy and shouldn't have anything to do with the issue you're having which is really odd. Perhaps something isn't flashed correctly? Just fishing.
So you mean to tell me that you ordered that part number from Ford and only got the ABS controller and not the HCU?
YES. I Used the part number P5SVO listed for my build date and Ford informed me that that part number was being re categorized. Read back a few pages where I mention that. Perhaps that could be the issue?

So I road tested again and perhaps I have the wrong ABS module? The truck will slow down
but as it slows down for the vehicle in front it triggers the cluster message Adaptive cruise not available. After it slows it will not regain set speed. Cycle the ignition and same results each time. I still need to double check the values but am almost certain they are correct. I Hit a wall? I bounced this issue off Livnitup as well. Being I did not swap the ABS ECU not sure how it was flashed but the shop told me they transferred my as built and did the PMI and IVD procedure. Seems to have worked well for P5SVO. So close yet so far! I pretty much have the same truck P5SVO but the 3.0 L diesel? I wouldn't think engines would matter though?
