CSP-23B57 for High Voltage Battery Notice

[LUXMAN]

We all know that Dealer service centers don't know their asses from their elbows when it comes to the Lightning. The mobile service guys, on the other hand, seem to actually understand things, or at least are better at explaining them in ways that make sens.e

As per my mobile tech guy: 23B57 stays active because of the "and/or" part. Primary action for it is the BECM update. This is what most of us got out of this CSP, but this alone will not clear the CSP because the "and/or" of "HVB module replacement". The BECM update needs to be in place for awhile before they can rule out your need of a HVB Module needing to be replaced, so they have to leave the CSP open else if the module did need to be replaced it's a much bigger paperwork PITA.

Not sure of the accuracy of this, but the logic seems right, and the mobile tech actually seemed capable, so I'm choosing to believe it.

They did my wife’s XLT at the same time and it cleared quickly.
it was done right after the CSP came out. What? Like December maybe.

I'll have mine checked out on the next tire rotation visit, assuming my HVB is stable with no additional concerns they can clear it then, also need to have them certify my self repair of the LVB sensor.

Did a check on my app, and it has cleared. Used the same dealer as @LUXMAN.

Yep, I used the same dealer as @LUXMAN also.
CSP 23B57 (BECM software) was done Dec 8th and is still there.
CSP 23B70 (BMS replaced) was done Jan 10th and finally cleared last week (and I got a service satisfaction survey today).

Dealer did state they like to keep 23B57 open for a few months in case a bad module develops which the new software is better at catching.

I'm in the same boat. Same exact dashboard indicators, same red lights when I tried to charge.

Right now, the truck is at the dealer for the 2nd week. My dealer has a bad reputation for not communicating with customers, so I have no idea what my status is. Thankfully I have a loaner (an Explorer).

I see a lot of mixed outcomes in the forums... some just took a few days, others had whole battery or module swaps and took longer, and some even ended up being complete loss with a Ford buy back.

Mine has only been in since Tuesday. And yes, minimal communication -just that they are talking to Ford. Some things I did behind their back so to speak:

Sent VIN to one of the PTS/FDRS guys on this forum and they were able to show that the dealer did the Battery Health test and its results (not good).
I also track location occasionally, always been in the parking lot.
Finally got a FordPass alert yesterday that the Powertrain had malfunctioned. My guess is they reset the DTC and it came back.

I keep checking the location too... two ways. The FordPass App tells me it's still in the parking lot, and I can tell the location of the keys from my Apple AirTag. I figured out from a previous repair of my old ICE F-150 when the key is in the office vs the garage itself.

I've also been keeping an eye on the charge level and odometer. I assume they will road test it at some point, but one thing I know is that the odometer has been identical since I dropped it off, which means they didn't drive it before starting the repairs. I assume they will need to test it after doing the repairs, so if I see it change, I know they're getting closer to wrapping up.

An update on my truck - it is at the same dealer as @bmwhitetx. Mine has been in now for almost 2 weeks. The dealer did their due diligence and truly the battery module was in range for the FDRS test, but it was right on the edge. Ford engineering weighed in and I'm getting a module replaced too. It has been ordered, but they didn't have / couldn't give me an ETA. I'm hopeful it will be there by Monday and hope to have the truck back mid-next week.

I'm very grateful they were able to get me in a Mach-E loaner.

 

[IdeaOfTheDayCom]

I'm still waiting, and yes... there has been NO communication, as always.

Anyone made progress?

Sorry you got this error. I like to have your opinion on something. I have had close to zero fast charging so far but a quick test charge in a supercharger seemed to drop my SOH by 0.05%. My voltage variations seem normal. I got my Tesla adapter but I am a bit afraid to take a road trip before doing CSP 23B57. What is your understanding of how much of a difference it makes. Is the main purpose of software update is to allow to crawl instead of stopping when stuff hits the fan? Or it actually protects the battery during fast charging in some way? I thought I would have gotten the update over the air by now but no dice. Trying to wait until I hit 10K so I can take care of everything with one visit. Did you guys have the update when yours failed?

I had the dealer do this update via Mobile Tech on 12/8/23. Got the Powertrain malfunction 3/29/24. Like you, I'm not sure whether the update makes the truck more sensitive or, when the error occurs, allows us to still drive with reduced power.

I have been tracking certain battery characteristics for a year using Car Scanner. You can see it was a relatively sudden occurrence, everything was within spec back in January (but % variation had been creeping up).

Date	Odometer	HVB SOH	HVB Age (months)	HVB Module Var. (V)	HVB Module Var. (%)
3/25/2023	2144	99.5%	5.95	0.01	0.25%
8/20/2023	4765	99.5%	11.01	0.01	0.33%
10/19/2023	5365	99.5%	12.98	0.01	0.26%
12/13/2023	6436	99.0%	14.78	0.01	0.40%
1/10/2024	6675	99.0%	15.7	0.00	0.44%
3/29/2024	7500	99.0%	18.3	0.09	4.56%

I had Mike G pull the Battery Health test the dealer performed on 4/3 and it shows the voltage deviation on cell 62 is 0.134 V from average. That's in Module 6 which the dealer is in the process of replacing.

I was hoping to add a little bit of predictability to it but your module 6 problem makes me think it is more like playing an exciting game.

 

[bmwhitetx]

Yep, seems to be unpredictable.

I am sure this 1 year old video is posted somewhere on the forum. If it is on this thread, let me know and I will delete it. It was new to me and interesting to watch. I am thinking my SR pack does not have the top three modules. Made me wonder how much this would cost out of warranty.

 

[IdeaOfTheDayCom]

My dealer told me they were waiting for some sort of tool to complete the repair, and from after looking at the video, it could be the thermal paste gun.

Anyhow, still waiting for them to get whatever tool it was and finish the job. They don't work weekends, so it looks like I won't hear anything until next week at the earliest.
