Several Mach-E Service Actions [Resumed] - Powertrain Software Issue

[Mach-Lee]

They did the update now my vehicle won’t charge. If I can’t charge then I can’t drive it.

If it's that bad, 23B50 isn't going to fix it. The software will only fix the situation where your car will charge for several hours and then stop because of overheating. If it only charges a couple minutes or not at all, then you have other issues that are going to require hardware replacement (new charge port or charger module). I would talk to your BEV case manager about this so the issue can get properly diagnosed.

Strange that it won’t charge. All 23B50 states is that the BECM needs to be updated (new transfer function for overheat protection).

FYI it's the SOBDM, not BECM. The charge port thermistor transfer function is part of the SOBDM software only.

why only vehicles updated from 4/26 will have to have the new software? My Mach E was updated in the week of 4/8 and I had the problem with 1PD.

Hmm...good question.

so.... are there specific version numbers of specific modules that need to be re-flashed (via dealer, FDRS, or OTA) such that it is possible to tell if you are 'done' and fixed ?

The version numbers are all different for each model year, battery, drive type, etc, so it would be an extremely difficult chore to assemble all those part numbers. The easiest way is to say if you have the 1PD issue, then you need the software updated in FDRS. If you don't have the 1PD issue, then don't worry about it.

You’re right, I just looked at the bulletin again. They mention BECM as not having the transfer function but then they say to update the SOBDM. Well in any case, doing SOBDM would also trigger the BECM and all other PT modules to update as well.

The hold has been lifted and the service programs may now resume. The new software is available that fixes the 1PD issue. Vehicles updated between 4/26 and 5/5 will need the software reflashed.

Just to be sure.

I had Programs 23S56 and 22S41 programs applied to my car between 4/22 and 4/23. I haven't had 1PD issue so far. Thus, should I consider myself to be safe or do I need to look for a dealership to have this software reflashed?

Thanks!

As of now, no.

Reminder to all - Dealers can only do what's currently authorized. They cannot just update the software because you're concerned about something that MIGHT happen. If it DOES happen, then you can go back and make a case.

I think I will still wait a week or two for Mike’s shake-down of his car. ??

Did those updates solve the drive mode switching issue too, or just the 1PD issue? ??

My car works fine now.

No drive mode switching anymore. I would get these updates.

Go for it!

Hmmm… I might be buying a weekend ticket to FordPass Land on Friday evening. ??

So, my dealership just called and said they're authorized to resume recall work on the HVBJB and we set up an appointment the 16th.

Was kind of surprised to hear about it from them before reading about it here on the forum (or maybe I missed it a few pages back?).

Sounds like the recall on the recall, has been recalled?

Edit: yup, I missed the announcement a page or so back on this thread. A couple questions though: What are PTS alerts and SSMs?

At some point, the outcome is bad enough (potential crashes & negative passenger outcomes ), and widespread enough (more than a few percent?), that updates would be not only authorized but mandated, right - like HVBJB was originally on failure then become everyone?

And we have*not yet* gotten to the point where the update has been recommended for all effected cars?

Unlike HVBJB, this is a case where the customer *could* do a "little white lie" and say it happened when it didn't, in order to get a known safety problem addressed with a known fix. While accidents seem rare with this one, I wouldn't want to be patient zero.....

Great to hear the issue was resolved quickly and updates are resuming.

This FDRS, are these the same handheld tuners they use on ICE vehicles or is it specific to an EV?

Neither. FDRS is a Ford computer program. It runs in the windows OS. It requires certain additional equipment including a power source for the 12v battery, an interface for the OBD2 port, and an internet connection. None of these are dependent upon the car’s motive power source.

Just got my vehicle back and it was indeed simply the 23B50 CSP needing to be performed again.

There were a couple of new powertrain updates issued through FDRS last week. The hold is still officially on, however. It is unknown whether the powertrain updates issued last week solve either the 1PD or the drive mode issues. ?‍?

@Mike G applied these updates to his car and I am waiting until he shakes his car down before I even consider popping them into mine. ??

I applied them on day one and no more 1 pedal fault or drive mode changes.. and PAKK is still working lol!

 

[digink]

I... was one of the (un)lucky few who had their HVBJB recall serviced during the week of Apr 15. And I started having the 1PD fault since then.

I spoke with my deler earlier today asking them whether they can update, but the person seems to have no clue and insisted I bring my car in a few week later, and said it would take at least 3 days to diagnose and fix.

Is there any chance the 'fix' can be included in an future over the air update? I really don't like the idea of taking two half days off work just for this...

(Edit) I think I read my answer to my own question on another thread - answer is 'wait'. https://www.macheforum.com/site/thr...ge-p0c2f-92-stored-in-the-sobdmc.35392/page-4

No, because the features like auto lane change will not be enabled. Using FDRS you get newer software but it will have the same functionality as now. Going further requires custom editing of configuration files which is for advanced users only and is not recommended unless you really know what you're doing.

Advanced users, as in Forscan Asbuilt editing?
Haven't folks been editing Asbuilt values with Forscan for many years now?

I'm not saying it's for everyone. Neither is FDRS, for that matter.
But if succeed at fully updating your vehicle with FDRS, the Forscan portion doesn't seem like the difficult portion of the accomplishment.

At least not to me.

As for the recent release of the Powertrain ensemble of updates in FDRS, they went pretty smoothly once I get the necessary files to successfully download.

Uploading changes with FORScan is easy. Knowing what as-built config to upload is the hard part. Somebody had to figure out first. There no "enable BlueCruise 1.3" routine in FORScan or FDRS if you have 1.0. It's manual editing of hex values. If you do know how, good for you because you're in the small minority of advanced users that can figure that out.

I just had an oil pump failure and had it replaced. They also replaced the HVJB and did software updates. After getting it back I have had at least 5 1Pd failures in a week of driving. Turning off and on it recovers. This is a software problem.
Ford? Are you going to get this fixed?

They've already got a solution. Turn off 1pd.
