CSP-23B57 for High Voltage Battery Notice

[Monkey]

Have this CSP showing now for me. I wonder if this has anything to do with why my truck can’t install updates?

Highly unlikely.

There is a battery health "tool" routine in FDRS that evaluates your battery pack. The reason I said that those in the listed build window would have to have their packs dropped is the inference that Ford thinks vehicles built during that specific timeframe time may have some issue with one or more cells due to some analysis they've done on failure rates they've seen during certain build dates. Trucks that are outside of those build windows will likely only get the powertrain modules updated (the BECM is in that group, but it is scripted to update with all other powertrain modules at the same time) and that's it.

I haven't seen the instructions to the tech yet so I don't know for sure, but if I had to guess I'd say the tech will be instructed to run the battery health analysis, and if it passes then just program the powertrain updates and job's done. If the health analysis turns up one or more bad cells then the pack has to come down for replacement of the bad cell(s), and then the powertrain modules will get updated after that's finished.

The mobile tech applied the updates and it ran a bunch of different screens.
he showed me the modules it updated but didn’t mention a battery health test
Everything was GREEN when he was done.
pretty impressive how the whole process was set up for him to run.

I encourage everyone who experiences reduced power to file a NHTSA complaint. It's certainly looking like the Lightning has a design defect with the batteries. These module failures have been happening for a year now. Our 80k and up trucks are going to be worthless if Ford doesn't take care of us. There are nine battery modules in the ER and no guarantee that all nine won't have a problem at some point.

I predict a huge lawsuit between Ford and SKS not to mention the inevitable class action.

I agree completely regarding the NHTSA complaints. Ford notified me on June 26 that my Lightning had a bad cell and required ONE battery module to be replaced. After 5 weeks waiting for the appointment, plus 2 days shy of 7 weeks at the dealership for ONE module replacement, I was advised yesterday when I finally got my Lightning back that TWO modules were replaced.

I believe the battery issue is much larger than what we are being lead to believe by Ford. My Lightning was the third one at my dealership for battery module replacement. I don't know how many more are in line behind mine. But, even 3 at one dealership does not equate to 1464 (4% of 36,611) in total. Per Inside EV's article on 12/6/2022 there were 1920 Ford Model e certified dealers.

I don’t think you’ll get a letter stating parts are available.
Ford used to do this years ago - I got one for the brake light switch recall on my 2000 F150, but no longer. The Mach-E/Lightning headlight switch is a good example.

I won’t be surprised. I think the service tech writer is just looking for a way not to have to write it up.

I keep checking the VIN on the recall site and trust me as soon as it says the parts are available, I’ll be on them again.

The CSP bulletin states “some vehicles may be in the process of being repaired at the plant.” Curious if anyone knows if the BECM software update associated with this CSP assists in the detection of the unstable voltage defect in vehicles that may have previously gone undetected before they shipped to dealerships?

So with a little help from a major Mach-E contributor (I don't have a PTS subscription at the minute), here are the tech bits for your reading pleasure and consideration. And apparently the techs will be running the Battery Health tool as part of the overall process, as I suspected.

So you'll see in there that the tech is supposed to select the BECM for updating from the list in FDRS....a little further down is where it lists the other modules that will be updated along with the BECM because they are all part of the coordinated set of powertrain updates.

Highly unlikely.

And yet the truck has been in service three times now, 12v battery replaced, truck has not had a successful update since early May. Not just OTA, It won’t accept an update directly either, they all fail. Codes point to a power reporting/ module issue. Service techs can’t get any info from Ford other than it’s being reviewed. Battery health scanners and other diagnostic all say the trick is fine. Truck drives fine, no errors or issues (knock wood), other than the inability to accept updates.

Sorry, I have no information about this recall other than I just checked Oasis and my truck is included.
I also do not have ANY information about the BMS as I have not deep dived into the data we collected on our test vehicle.

I will tell you about the danger of mismatched voltages...let's say you have a string that is sitting 0.5 V above the others. As you charge up to 100% (4.2 V using CC/CV) that string is now being overcharged and is more likely to go into thermal runaway. A cell 0.5V below others can be damaged if going down to 0% SOC, but the dramatic effects are not near as great.

When we are charging a module up to 100% SOC without an active BMS for a safety test (all the things manufacturers tell you not to do ), I require an engineer to sit there and constantly monitor all the string voltages.

Now for the big takeaway...am I worried about my pack being included? NOT AT ALL. Do you remember what I've always said to charge to unless you REALLY need to go above it?

80 or 90% if I recall correctly.

I have no doubt there is very likely a problem with your truck that’s preventing you from getting updates. I just don’t think the modules being updated for this battery issue will fix it.

You’re probably right. I’m just hoping for a direct resolution.

85% of usable

85% of usable

Which is the SOC figure our trucks tell us on the dash, the app and the electric charging station (if equipped), right? Just trying to make sure we don’t have to do higher math.

Yes - because 85% displayed is approximately 80% of total capacity which is what you’re shooting for.

85% of usable

Should we shoot for that even if we don't need it? My day to day driving is minimal, I almost never charge higher than 80% of usable so I was actually thinking about dropping my normal charge down to 70% or so, or would that be worse for the battery?
