DIY: Installing Passive Entry To A 2022 F-150 Lightning XLT

[grantmethepower]

Just a second piece of advice. Please do allow yourself to get familiar with FORScan and configuration changes and using the dashboard any just poking around, checking DTC, etc. before doing "MFU (Module Firmware Update)" I think FORScan goes a little bit overboard on the warnings and liability BS, but it's understandable because some people would just jump right in and try wild things. If you're on this forum following good advice you're probably OK, but still it helps to be familiar with FORScan and start slow, it's not the most easy piece of software to understand.

Ok, I was able to get everything up and running and I went ahead and saved each module's AB and labeled each with todays date and identifier for which it was before changes.

I then did two small changes-I turned off the panic button on my key fob and the reverse brake detection thing off. Both seemed to work just fine. I get the hang of the way it works for those basic changes.

Where I'm at now though is to do the module update. From what I read it sounds like what you're saying is that the firmware needs to be updated to tell the truck that the physical hardware is there before I should make the changes to BCM numbers. Is that right? How do I do that exactly? I read the FORScan forum and its a lot of warnings but I dont see exactly how.

I saw this you posted but I dont see where these are exactly. None of the tutorials I could find talked about the MCU process. Sorry to bug you again. Hopefully this is it!

Another issue. I disconnected FORScan after playing around and plugged it back in. I suddenly got a bunch of errors. All of the modules in fact showed DTCs.

I disconnected and reconnected and when I did I did not select my first vehicle save, instead letting it rescan everything. This time, there were not DTCs everywhere-just three of them.

It says BdyCM B1587:13-48 Driver Door Unlock Output, BdyCM B1616:04-08 Code B1616 - Electrical System High Key Off Load, IPMA U2101:00-2F Code U2101 Control Module Configuration Incompatible.

Did I mess things up? Here are a couple screenshots. I'm going to stop until I hear back. Maybe I got too adventurous in testing it. Note-I did open the Module Firmware Update configuration to play by clicking download and test, but I never clicked program. I dont know if that messed some of this up or if it was my earlier changes or what.

Thanks.

Just incase anyone else is looking to do the passenger side, according to Varsity Ford the correct part number is NL3Z-14630-G. I'm going to order it and I'll let everyone know when it arrives.

I can confim that this is the correct wiring harness for the passenger side, and also the Bronco handles previously stated work perfectly for the driver and passenger side (just the covers, not the internals)

Not sure on all the errors, but the firmware files are ones that you would actually get from ZSC100. You really can't screw them up, but they're loaded one by one into the system. It's not like the other forscan changes that you'd make.

Ok, I'll wait on the firmware files from him. I just did a test drive in the mean time-the vehicle seemed to run just find EXCEPT it said "pre-collision assist unavailable" and the driver display did not show the driving assist.

Is it possible I messed something up with the wiring for that?

 

[grantmethepower]

Ok it's getting weirder (and worse). I didn't want to mess with Forscan any more until I heard back but I did a search for "precollisin assist unavailable" and one tip was to disconnect the 12v. I've done this before to change my steering wheel. no prob.

I disconnected it, reconnected it, physically closed the frunk as required, started the car-precollison assist unavailable was still showing. So I didn't fix anything.

BUT what is now wrong is the frunk button doesn't work any longer. I press the button and it doesn't lift. I used the button instead the cabin and it worked opening and closing it, but it wont open or close using the button on the hood.

I dont understand what could possibly have started all of this. All I did was replace the wire harness in the door and change two numerals in FORScan: 1. for the kayfob panic button (changed from 2 to 0) and one for the brake assist (changed from 5 to 4).

I could try changing those two back but feel like I should wait for more direction here first.

Can you post exactly what you changed? Like what lines they were and everything?

 

[grantmethepower]

Can you post exactly what you changed? Like what lines they were and everything?

Yup!

Change 1 was:
BdyCM 726-62-01 FROM: 0201 0050 00E3 TO: 0001 0050 00E3

Change 2 was:
IPMA 706-01-01 FROM 0E00 8015 0ABC TO: 0E00 8014 0ABC

That's all I did in FORScan with the "write" function.

In addition, in the BCM Module Firmware Update all I did there was click the "download" button and then the "Test Run" button. I never clicked "program"

Unlock your doors and try the frunk button again

Unlock your doors and try the frunk button again

HAHAHHAHA.....that worked! I'm laughing my ass off.

It was weird because the door WAS unlocked, so it didn't occur to me. I've also disconnected and reconnected the battery a number of times before and never had this issue so I assumed I had messed something up.

Still having the problem of the precollision assist unavailable but at least the really weird and dumb problem is fixed lol. Thank you!

Final Update for today and hopefully last time I need your guys' help with this project lol. I have not felt like such a novice at anything in quite a while and can't express my gratitude enough to all you that have been helping.

First-I still have the Precollison Assist Unavailble warning on the dash, no drivers assistance and the DTC still shows up. No idea what thats about but it was not there before the project. I cleared the other DTCs from the BdyCM and they did not come back. I’m guessing that since it is in the IPSM module and I only changed one integer there for the annoying rear back up alert warning everytime that it must be related to that. Is it best to just change that number back to what it was or to reload the saved file completely?

Now, I have updated all of the BCM files from Zach's post here:

There were two I did not update-the final two. These were already in my Forscan as the green versions for some reason (2023 Pro)

I was then able to load the two modules (lk lf lk tch and ul) and test them in the dash board. They "worked" in that if I touched the button one would say yes, then if I waited a few seconds and touched again, the other would say yes. They did not respond if I held or touched over and over (which makes sense I suppose)

I then decided to see if I could figure out HOW to do the firmware upgrade without actually doing it. I got to this point and wanted to make sure that I am supposed to have it look like this and then press "program". Is that right? Is there anything else I am supposed to do first or after? Is that it? Here is what it looks like. I did not click any other buttons, just hit stop after selecting the files to make the screenshot.

Finally, after doing all of the above I checked for DTCs again and lo and behold not only do I have the precollison one there but a new one now popped up for some sort of trailer thing. Would this have been related to a flag or integer I changed? What's weird is that it is in the TRM module and I did not do anything in the TRM module BUT it says "lost communication with body control module"

So, where I'm at:

1. Need verification that all I do for the firmware is select the files in the manner I have above and then hit "program" and that my dashboard indicates the hardware is correct.
2. Assistance with the precollison issues
3. Assistance with the TRM issue-must have been something I did from the list of forscan changes for the door sensor, right?
4. To redo my handle so it’s prettier hahaha.

Thank you guys a ton. Super appreciate it all.

1. Yup, that's all you need to do. Just make sure you're using a wired connection to your computer (at least that is what is recommended) and you have sufficient power on your laptop and truck. It's pretty much foolproof, you can't even select a wrong file. Forscan defaults to the one that you need to install.
2. I would revert back any changes that you made. If you know what your values were originally, just switch them back. If you saved your asbuilt values you can just reload those.
3. You'll get various errors and dtcs just from unplugging items. I'd just clear everything out once you're done and see if anything comes back. I get DTC's from time to time anyway, I'm assuming that anyone can (mine seem to come from the adaptive cruise control not being able to read speed limit signs every once in a while).
4. You can always buy one of the bronco handles and use them, that's what I did! My handle wasn't that bad but I couldn't deal with the slight imperfection and just bought the bronco ones for the driver and passenger sides. I'm just going to resell them with the primed handles that I got with the lightning passive entry handles, so should be able to recoup some of the cost.

 

[jdmackes]

So now that we've figured out the driver and passenger sides, does anyone know if it's possible to do the tailgate? Does the tailgate on the XLT even have passive entry?

thanks a bunch for the reply. Thought about this all night haha. I’ll try to first fix the ipma issue, then do the firmware, then update you.

Also, good call on the bronco handle. Looks like it’s about $40 more. As much as I feel confident I could do a better job, I’d still need to buy another dremel bit because that was a limiting factor and even “better” isn’t factory perfect.

again-I really appreciate your help

the frunk would be super cool!
