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

[jdmackes]

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 Bronco handles are M2DZ7822405CB and M2DZ7822404CB if you are doing both sides. You can just pull the cover off and then put on your primed ones from the F-150 handles and resell them, that's what I'm doing.

thanks! I found your comment confirming those earlier in the thread. Just reached out to see if I can cancel the order I placed late last night for the f150 handle lol.

You'll still need the f-150 handle internals, the bronco passive entry hardware isn't the same as ours (unless you're referring to a different f-150 handle cover)

right copy that. I already purchased the primed f150 handle and installed and verified with dashboard. This is just for the aesthetics of the cover because I scratched up the handle a bit with the collect on the dremel. Oops lol.

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?

You're probably totally fine on the errors and such,, I've had weird things happen a few times like that after plugging/replugging and through power cycles. Just turn off the truck completely, close FORScan completely and start again, that usually fixes any issues. And don't be shy about clearing all DTC's. I always have a few DTCs set in a few modules after just a day of not hooking up. These trucks are just very sensitive about "non MIL light DTCs" I bet you there isn't a lightning out there in the world without at least one DTC if it hasn't been cleared in the past 24hrs.

I finally updated the very first post with a link to the firmware so I wouldn't have to send so many times,, and FORScan team has them too, but they respond slow sometimes and it's touch to ask for the exact right thing.

So, one last thing, Firmware and Configuration are two separated things intentionally. You can go ahead and make every single passive entry mod config change before you do the firmware update (MFU). In fact I suggest you do the config changes then test the passive button with the dashboard feature,, you can see the sensing of your hand real time, then you know the wiring is all correct before you do the MFU.

Thanks for the reply. I did use the dashboard feature and I did see the change from “no” to “yes” on both features one at a time.

one question on forscan (I’ve seen different recommendations on my day of ‘learning’ yesterday)- should I select my same truck’s profile each time or should I have it run a full scan each time?

thanks again for everything

I don't have a real good understanding of EVERYTHING that happens with the profile save, but judging by looking at the raw text file of the profile I think it's main purpose is "module discovery" to tell FORScan what to make available to you in the GUI. So, if you have not added or removed any modules from your vehicle, go ahead and save then select your profile every time.

The door handle is not a module (in the sense of FORScan) so, no worries there

For instance after I added the CCM (radar module) during the ACC mod, I deleted my profile and let it scan and discover the CCM, once I saw it in the discovery and module list I saved a new profile and have been using that sense.

Great question, it's questions like this that tell me you are paying attention to details and curious about how things work.

that makes a ton of sense! So that profile isn’t saving any of the configurations or firmware, just the structure of the build. I appreciate it!

is there a best practices approach to backing up the firmware before updating or is it just that if it gets bricked to try again? I saw there was a factory setting but I’m not sure if that is something to trust or not.

So, the way FORScan works with MFU is that it knows what the factory firmware should be on your vehicle based on the VIN and its knowledge of FDRS somehow. There is a "FORScan firmware server" that I'm still not sure anyone can actually access other than asking via email, but at the bottom of the MFU section in the program there is a "download" button. If you select the dropdown in the firmware section to revert to factory firmware and push that download button, apparently FORScan knows how to download your factory firmware in the background and load it, then all you have to do is hit GO. I did use this once when I was trying other firmware on my BCM and it worked as described.

that’s sort of what I guessed just looking at it but it’s the magic of knowing and finding it behind the scenes that I did not understand lol. Thanks for explaining!

Guys, you are not going to believe this....it is done and working! AND NO DTCs!

First, I undid the change that I made for the IPMA. This was a "practice" change and was from Livnitup's common changes to remove the rear brake assist warning. I only changed the one integer he said, but it caused the driver assist and pre collision system to fail. Changing it back makes it all work (but I get the back up warning again). Oh well. A different problem for a different thread.

Then I cleared all of the DTCs. Made sure everything looked good and worked right. Did one last dashboard check to verify in real time that the sensors were being read and went ahead and loaded the firmware files. Hit program and held by breath for 2 minutes.

Boom. Car started right up when it was done. Hit disconnect. Tested. Magic.

MASSIVE thank you to @ZSC100 for figuring this out and providing so much help as well as to @jdmackes for their help as well.

Now for a sigh of relief, figure out how to stop that brake warning, and decide if I can tackle the ACC project lol. I really want it but it looks even harder!

ACC isn't all that bad, especially if you have the tow tech package on your truck (or maybe it's the max towing?). That way you wouldn't have to run the 4 extra wires from the bumper to inside the cab and it becomes a project that only takes a few hours!

I read that whole other thread...and its the wires that worries me haha. I have a base base 2023 pro. No options at all, no tow tech or max tow or pro power.

I'll go check the wires and take pics and switch to the other thread. I need to get a firmer understanding on the options if I don't have the wires. If, somehow, I do, then it's a no brainer! I really want it but getting those wires routed through the firewall and keeping it all looking nice and clean is a little intimidating.

Thanks again!

Does anyone know if the XLT has passive entry on the frunk and the tailgate? I'm going to see if varsity ford can tell me what the part numbers are but I don't know 100% if the XLT even works like that.

Got everything working on my 23 Pro. Installed everything a couple weeks ago then got distracted. Turned it on with forscan this morning. Worked great. I did a terrible job with the Dremel and couldn’t live with it. Ended up grabbing the bronco handle cover and it looks perfect. Here’s my install video if anyone is interested. Thanks again guys.
