Pro Trailer Hitch Assist via OTA update for MY22?

[KingStraasha]

So...for my 2023 Lariat ER, I have for ABS: 760-03-01 is CCDA 11. We are focusing on the 3rd number, xxXx.

So, by looking at the hex to binary conversion, @Firn has a 9, which translates to 1001. I have a D, which translates to 1101. The order goes: AFS (AFS) • CTA (CTA) • PIB (PIB) • AutoHitch (AH).

If I assume that @Firn 2023 Pro does not have cross traffic assist (CTA) while a 2023 Lariat does, then D is correct. Thoughts from the team?

I am not making any changes and will attempt to connect to my travel trailer when it is not in a storage garage. When I tried it before, it was in the garage and did not work.

That seems correct to me too. Make sure any DTCs are cleared for the reverse brake assist, before trying also.

I made changes last night and it didn’t work, so I changed things back. Then my reverse brake assist didn’t work until I cleared the DTCs. I’m wondering if I had cleared them, then tried the hitch assist if it would have worked correctly.

I will try again tonight.

Fwiw I have BLIS and cross traffic alert/assist.

@Ford Motor Company are there any plans in the pipeline to bring this feature to 2022 & 2023 Lightnings?

Let me find out what I can.

In this post @RickLightning says he got Pro Trailer Hitch Assist (aka Auto Hitch) on his 2022 after an update.

I just checked my 2022 and when I press the ProTrailer button, I get asked if a trailer is connected and when I answer no, it seems as if Pro Trailer HItch Assist wants to start. It was dark so I got a message it was too dark for the feature to work. I'll try again in the daylight.

Regarding the FORScan values shown above be careful; since they are for an Ice truck. Here are the values for my 2022. You need TowTech for this feature to work I believe:

706-01-01 xxxx-xx*x-xx - was originally a 1 but an update changed it to 5 late last year.
7D0-01-03 xxxx-xx*x-xx trucks w/o TowTech have A, with TT have B
760-03-01 xx*x-xx trucks w/o TowTech have 9, with TT have D

The values above also apply to 23-24 MY Lightnings that have the feature. I imagine you might also need an IPMA and ABS update from the original stock.

So I changed my 706-01–01 xxxx-xx1x-xx from a 1 to a 5. Everything else matched.

All updates except the latest BCM I completed in August.

When I press the pro trailer button I get asked if a trailer is connected, I say no, and it says Pro Trailer Hitch Assist is not available. With an orange bar across the lower part of the camera.

Any time you write to the IPMa you have to drive straight for a few for it to relearn center. SO the likely hood of errors and RBA not available is high. Its best to drive it after anything is writen to IPMA to relearn center then try it

There is also a PCM change needed to make it fully functional.

Thank you! I’ll give this a try

May need to update the PCM also. I had figured out an issue a long while back with a PCM OTA ford was sending out. It was causing a wrench Icon to show up.

It was due them enabling the Auto hitch in the reconfigure of the OTA on trucks that didnt have it enabled.

So some PCM strategies for earlier trucks MAY not have it. So there could be a scenario that you need to update the PCM strategy to make it fully work.

I did ALL the updates available back in August. (Only missing BCM with WAL)

I made the above edit to PCM, rebooted it, and drove about 10 hwy miles. Lane centering and ACC all working fine. No RBA errors. Still coming up with same screen on hitch assist.

Will just leave it for a few days and try again.

So mine seems to work now that I have tried it in the daylight. I press ProTrailer button, say No to trailer attached and I get an Initializing message:

I don't have a hitch nor a trailer so I get an error:

I haven't made any FORScan changes. My value for 7E0-163-04 is 01, not 02. I see that 2022's have 01 and 2023's with TT have 02.

I may put my hitch ball on and go visit our Scout trailer to see what happens. Curious what other 22 owners with TowTech see if they press the button.

One other thought is to do a module reboot with FORScan.

After making the change you posted, mine seemed to work. I said no trailer, then it popped up a target that you had to aim the truck at the trailer you want to hook up and I guess once it recognizes it, it takes over. I dont have a trailer at my house or I would have tried, but I assume it was working as intended.

 

[theaustinite]

Still says not available for me….

 

[KingStraasha]

After matching the changes, Mine still says not available as well.

Odd that the two of you with 2023's don't have it. I thought it was a new feature for 2023's. Were you early builds? @theaustinite says he did not get the BCM or WAL update. Did you?
