Powertrain Malfunction - P0B24 Error codes - Need a New Battery

[gapsd]

So I just got the dreaded Powertrain Malfunction code on the dash.
I had just taken my 2022 truck in to get the recall software updates done, and while driving off the lot the wrench appeared. Luckily I was still on the dealer lot and could just stop and go back into the service center.

Now the dealer is telling me that I need a brand new battery.
I have questions about the process from anyone who has gone through it, or knows about it.

• I am being told the battery is one back order. Should I expect a 2022 OEM battery or a new OEM part?
• Is end of Feb a realistic expected completion date?

I have many more questions but still in a bit of shock. I am sure as I read through the threads i will have more. Any advice or info is appreciated.

Thanks

Hopefully you find all the questions in the thread Dean has referred you to, but 45 days to get your truck back is a bit long, I don't know the particulars of the dealer service workload ahead of you and the logistics feeding them the required module(s) to repair your battery pack, hopefully it's just a single module swap (one of nine gone bad in the pack), it's very rare to swap an entire pack one for another.

It is quite a coincidence getting the wrench right after dealer visit. May I ask which software update it was?

If your truck requires a battery MODULE replacement you can escalate the part with Ford. It only takes a couple of days to replace a module but the parts will have to get there first.

Unless aftermarket modules are now on the market (which they're not), you will of course get an OEM one.

As @Maxx inquired, if you just had the software update for the hvb system it may have detected an out of tolerance cell with the new limits.

This!

That update also instructed the dealer to run a module test before applying the update & replace module(s) if necessary. We had at least one other person on here whose dealer only applied the update and he got the HVB error soon after. Sounds familiar.

After looking through the threads the most common theme was the @Ford Motor Company reaching out to the OP.

Also looks like a new module, not a whole new battery like I was originally told.

With Part number NL3Z 10D672E being replaced.

Thanks, I will keep reading.

see my google spreadsheet in my signature, 2022 models in particular have a higher rate of failure. @Adventureboy has a thread comment somewhere about a way to allow the cells to rebalance by charging to 100% periodically and some other steps. I wonder if that would help avoid a battery cell getting out of whack?

Balancing certainly can't hurt, but it should not be necessary to keep cells from failing. I think the early HVB management software didn't keep as close of a watch on individual cells as it should have. I'm hoping OTA/CSP updates have corrected that by now.

Probably the most challenging thing for individual cells is deep discharge cycles taking HVB SOC into single digits - This is pretty hard on the cells, especially if they aren't balanced periodically. Try to keep it above 15% SOC whenever possible and try pretty hard to keep it out of single digits.

CSP 23B57 was issued to update the BECM which hopefully also improved HVB management. In some cases, when the BECM was updated, it flagged battery modules that were already out of spec and some folks had to have battery modules replaced when the CSP was applied. It affected all 2022s and 2023s.

Awesome tracking sheet. Is this info from the Forum here or is it other sources as well?
Thanks for doing this.
