I never got the message but my FordPass app (iOS) is really pretty gimped now. On the "Vehicle" tab it just shows the "Vehicle Status" and "Scheduled Start" buttons underneath the battery and fuel gauge, and then a "Status" section with "Tire Pressure Monitoring" and "Oil Life". That's it. Prior to this update, I used to get a blue bar across the screen whenever the car was plugged in, which was helpful at a glance so I could double-check that I had remembered to plug it in. That's gone now, and the only way I can see if it's plugged in is to look below the battery gauge on the Vehicle tab for the lightning bolt icon. There's no more estimated charge completion time (which, to be fair wasn't very accurate anyway, but still). This is Ford throwing in the towel, I guess. They couldn't make any of the extra stuff work reliably so they just gave up and removed it. What's left is very bare bones, but at least I can still keep an eye on the battery charge progress and lock/unlock/remote start. Still, it's pretty disappointing after the MFM experience, which was fantastic overall. Not sure if this was a server-side change or if it was an app update. Are android users seeing the same thing?

Oh wow, I definitely don't check this site often enough. Sounds like Ford decided to throw in the towel rather than spend any more $$ trying to shoehorn these older vehicles into FordPass. I don't believe that I have (yet) gotten that message for my 2017 C-Max Energi in my FordPass app (iOS, in case that matters). For those of you who got the message, did it pop up automatically when launching the app? Or did you have to go into the "Message Center" to see it? I suppose it's possible it was there and I somehow closed/missed it, but I don't think so. That said, I expect we are all affected whether we get the notice or not. And I guess I shouldn't be terribly surprised, since those features hardly worked to begin with. The only one that does seem fully functional for me is the charge log, but I very rarely look at it. Preferred charge times sort of works, but back when I messed with it I found it quite buggy. I never use Departure Times so can't comment on that. The trip log has never worked--not even once. I am of course disappointed that Ford is removing these features. But if I'm being honest I'm not going to really miss them. I only charge away from home in extremely rare circumstances. I try not to charge at level 2 anyway since it puts additional stress on the battery. I use a simple Smart WiFi plug to turn on my level 1 charger overnight when temps are coolest. I park in an insulated garage so I've got no real use for pre-heating/air conditioning the cabin. Actually, the feature I miss the most from MFM was the status of the door locks and windows. I'm slightly absentminded at times, so it was re-assuring to be able to pull up the app after I'd left the car to verify that I remembered to lock it and roll up the windows. That was never promised to be carried over to FordPass, and this latest update from Ford makes it sound like there's even less chance now. Oh well, I'm still glad I did the update. I do somewhat regularly use it to check on the charge level of the HVB, and it's reassuring to know that I can remotely lock/unlock/start if the need should arise. Guess this just reinforces the notion that car companies are basically incapable of retrofitting. All of their effective engineering is done prior to a model's release. Things they try to do after a car rolls off the assembly line don't seem to have a very good track record. @Cellivar- Late last year myself and many others got their FordPass accounts disabled by Ford due to using third-party apps to interface with our vehicles. In my case it was a HomeBridge plugin, but I know people using the HomeAssistant plugin as well as other 3rd party solutions were also affected. Getting the account re-enabled required several calls to FordPass and basically promising to not use any 3rd-party apps with my FordPass credentials (they said if it happened again my account would be permanently disabled). I'm unsure if anything has changed in that regard, but at least as of then it sounded like Ford was not on-board with 3rd party apps accessing their data.

Sorry for the late reply--haven't been in the habit of checking this forum since all the frenzy around the 3G shutdown and TCU swaps subsided. My 2017 Titanium (with Sync 3 stock) did *not* have the climate domain and temp/fan repeaters enabled by default. I enabled them via Forscan after updating to Sync 3.4 and both work. I vaguely remember there being a small issue with the on-screen AC button indicating the reverse of what the physical button does. Can't remember if that is still the case but will try to remember to test it next time I'm in the car. To be honest I almost never use the climate screen on Sync3 because I have CarPlay active 99% of the time I'm in the car. I do really like the repeater though as it's much easier to see the temp and fan setting on the bigger screen than on the small LED readout by the physical climate controls.

You need to talk to a dealership. Tell them CSP # 21B09 - that should have all of the relevant part numbers and info. If you've struck out with your nearest dealership then maybe try calling a different one in your area or a nearby city. That said, installations on the C-Max have been "paused", supposedly until Q4 2022, which has elapsed. I'm not sure if the delay has been extended or if they're doing swaps in the C-Max again. Ford dealers get regular communications from the Ford mothership so they should be able to look up the most recent info/instructions using that CSP number.

I assume you still have the 3G (or even 2G?) modem installed. There are two possibilities--either the modem is locked up or it's dead. With the car off, pull fuse 67 out and reinsert after a couple minutes. If the modem was locked up that procedure should reboot it. If that doesn't work then the TCU may have gone belly up. In that case, the TCU would have to be replaced. If you've never messed with fuses before, they're in the passenger side footwell. Sort of a pain in the ass to access but doable.

OK, then it must be a misprint in the cyanlabs database. I will let @f150chief know so he can correct it. As you've seen, the problem with changing more than one as-built value at a time is that it doesn't help you figure out which value caused which change in behavior. So you might want to revert everything back to the working configuration you started with and then change only one value and wait a couple of days to see if there are any effects. Then change one more value, etc. I know that is easier said than done, but given how little documentation there is about how these TCUs operate we are basically left to reverse engineer everything by observing cause and effect. The antenna DTC is completely normal as you said. If you are getting lots of other DTCs with the as-built changes you made that is a very strong sign that one or more of them are not configured properly. So that's another reason to change just one value at a time. If that triggers a bunch of DTCs (that return if you clear them) then you know that particular change is incorrect for your particular vehicle and you should either revert it back or try a different value (if there are multiple to choose from). The 754-03-xx are mainly all data collection parameters, and have recently been documented in the cyanlabs database. According to f150chief, setting to 7D enables data collection for that particular parameter and 7C disables data collection. We have been operating under the assumption that there is no harm to enable all of them (and indeed this is how Ford configures the TCU when doing the 4G TCU swap at a dealership), but who knows... maybe it's possible that some of that data should not be collected and causes problems when it is--I don't know. But again, if you're going to test that you may want to only disable one parameter at a time and test to see if any changes in FordPass.

With the K->J TCU I also had the Horn/Lights button but it did not function at all for me. Although again that may be due to the C-Max being on the older C1MCA architecture vs. the Fusion which is CGEA 1.3. According to the cyanlabs TCU database, 754-03-06 corresponds to "HEV Data Monitoring Alert Publishing Frequency", where 0078 = 120 minutes and 00E1 = 30 minutes. Not sure why it would result in anything disappearing from the app, but then again according to your screenshot you still have a "Charge Settings" button. What shows up when you tap on it? It's possible that the change in FordPass is unrelated to the modification you made to the as-built. I guess the true test is if you set 754-03-06 back to 0078, does everything switch back? Edit: Just noticed that you said you changed 754-03-06 to 001E. The database says that the 30 minute value is 00E1. I am not sure which of those is correct, but you might double-check which one you set it to. If it's supposed to be 00E1 and you set to 001E then maybe that is causing the problem you are seeing.

Pretty sure that L TCUs won't work at all because they are HS4CAN only. Their hardware is different so they cannot be flashed to J calibration. Remember that K TCUs only work in our HS3CAN/ICAN vehicles because they can be flashed backwards to J-level firmware. Thanks for the extra screenshots. Your experience is similar to when I had a K->J TCU installed in my C-Max Energi. Most of the functions worked but Departure times nor Preferred Charge Times did not work. Tire Pressure Monitoring also did not work, but I think that is because the C-Max is on the older C1MCA architecture vs the Fusion which is CGEA 1.3. As you say, maybe a firmware upgrade for the J TCU will be released some day to allow the charging settings to work the Fusion. But even if not, the functions that do work are still better than no TCU at all! Cheers.

Glad you're having some success. Your screenshot of the TCU PIDs in Forscan shows "Unprovisioned Mode". Did you take that screenshot prior to authorizing the TCU in FordPass, or is that what it says even after you authorized it? Can you post a screenshot of what your "Charge Settings" screen shows? Also, are you getting any data in the "My EV driving" section? What about "Tire Pressure Monitoring"?

For anyone who hasn't had the swap done yet, found out from a tech at Ford that all C-Max Energi installations are still on hold pending new software, which is not expected to be available until the 4th quarter of this year (so September at the very earliest). Obviously that stinks for people who are still stuck with a nonfunctional 3G modem, but the (potential) good news for all of us is that it sounds like Ford is trying to fix at least some of the broken FordPass features.

Yes, I asked @f150chief about this a couple months ago and he said the 754-01-01 xx6x values map the same as 754-01-01 xx3x values. So what they have in 754-01-01 should be correct/fine for their Fusion Energi. I'm still curious/skeptical that they have properly-functioning value charging profiles and go times, because the screenshot that was provided looks exactly the same as mine looked when I had a J TCU installed (and those functions did not work). Not saying it can't be made to work (and indeed I hope it can) but what I have seen so far doesn't seem to show it. Please keep us updated on your progress, @JoSS!

Wait, Kuga Energi? If I google "Ford Kuga Energi" I get three results, two pointing to a press release back in 2017 where Ford trademarked that name and the third result is this post of yours. Can you clarify what vehicle you're talking about? Also, the screenshot posted is exactly how my FordPass app looked when I had the K (flashed to J) TCU connected in my 2017 C-Max. There was always a "Charge Settings" button in the Charging section of the app, but the options inside it did not function. Here's a screenshot I saved of the "Charge Settings" screen. I think that is intended for newer EVs like the MachE: With the H TCU, the "Charge Settings" button shows a screen that looks like this: Furthermore, in the Charging section there are other buttons for "Charge Level Notification", "Charge Logs" and "My EV driving": Maybe Ford has/will make changes to allow a J (or K->J) TCU work fully with the Energis, but the screenshot you posted doesn't look any different from when I tried this back in March.

Interesting. My understanding is that all European C-Maxes had petrol or Diesel engines. Not doubting you, but maybe the guy in the Netherlands got a prototype or some sort of special modification? Anyway, if you can find more information about European C-Max Hybrid/Energi models I would like to read them. Unfortunately, it's not just a matter of HS3/HS4. The "J" TCUs all communicate via HS3 and they will not show the PHEV charging settings in FordPass. I really hope you guys can figure out a solution! BTW: I think the guy you mentioned in Poland with the Fusion Energi is the same guy I was talking about in this post.

It's an interesting idea. You might try to get in touch with this guy as I remembered back in March he was attempting to get HS4CAN in his Fusion Energi. Maybe it would be easier to contact him over at the Fusion forum. I'm not sure if he ever followed through and got it working, but you can search for his prior posts and maybe he can update you on any progress he has made since then. There will likely be some differences since his car is a Fusion (CGEA 1.3) vs. your C-Max (C1MCA), but maybe the overall process/parts are the same. In any case, please update the thread if you are able to do that. Like you said, if there is no H TCU for the European market then I am not sure that any other easy option exists. Ford may not have considered it since the Energi models were only sold in (and intended for) the NA market. I wish you good luck! Edit: The only other idea I can think of would be if it was possible to obtain an H TCU from the USA and see if it's possible to transplant the cellular modem (which I assume uses an ESIM) from the K TCU to the H. I'm guessing that would require some precision soldering, and it may not even work. But it is an idea to consider maybe.

Check out the posts right above yours. I tested a K->J modem extensively back in March and found no way whatsoever to get the PHEV/BEV-specific features working. It still mostly worked fine for locking/unlocking the doors and reporting other info (odometer, battery level, location, oil life) but Go Times and charge scheduling (the stuff that Ford specifically added for the Energis) does not work with a J or K->J TCU. You need an "H" TCU. Once you get one, those features will show up straight away.
