CSP-23B70 Certain 2022-23 F-150 Lightnings - BMS Sensor Replacement

[RickLightning]

Has anyone had the sensor replaced and noticed a change in behavior with software updates/prior failures to install? I'm getting mine replaced next week, and wondering if there will be any miraculous updates that I finally receive (I'm on 6.4, but a few weeks ago I got the release of 6.2, and still waiting for 6.8 or 6.13).

No updates for anyone in weeks.

My last update was 6.8.0 before the end of year / holiday hold.
Nothing has tried to download since.

Mobile tech replaced mine today in less than 5 minutes. Just a quick parts swap. No other resets were performed.

How does one get a dealer to agree to do it via mobile service?

Your dealer needs to provide that level of service, not all do.

Had mine done this morning via mobile service. Not sure if they reset the system? Nothing had changed with the truck. I was expecting to have lost settings if they did that?

I lost Radio presets since negative was disconnected. And Brake Coach turned back on.
No need to reset the system. The sensor itself stores the values, so when old sensor gone, old values gone.
FYI, it does mean your PCM thinks you have a new battery - whether that is material or not I don't know.

At this rate I might as well wait till I rack up 10 CSP actions and get them all done at once

This is what I did...fortunately they sent a mobile tech to do all...but...one (heated steering).
Then while doing heated steering later, the frunk module eFd up, so now I get to do that...when...the...part...arrives....

Mail Call [/Klinger]

Tasca mailed out my order from Cranston RI yesterday morning, USPS delivered my order today!

Checked the Software updates to make sure there was no background downloading in process, shut down the truck, checked FORD.COM to see what the LVB SOC was before making the change, it was at 56%.

New BMS was manufactured 10/10/2023

Removed the old BMS, cleaned the battery post and negative battery lead to ensure a good contact, reassembled and tightened down the fasteners. Within a couple minutes I heard the HVB contactor engage and heard a coolant circulator fire up, likely the DC/DC converter was active and beginning This is what it shows a couple minutes afterward, being under 40% proves out the need for immediate recharging and why the systems autonomously began to replenish the LVB.

The SOC has risen to 49%+ since then and I am idling [RUN] mode with lights off, break set, doors locked until 1300 hrs

I'll update this post later in the afternoon once our errands are done.

Which part number did you use at Tasca?
I searched ML3T-10C652-B and ML3T-10C652-BA but nothing was found.

Thanks. Interesting that the part number on the photos show "ML3T" versus "ML3Z" to order.

Got mine done at the dealer today.

They did a couple of other software updates too.

Maybe it will keep 12v battery at a higher charge %?

Maybe I will get some OTA updates since I got knocked back to 6.3.X.

Right.... This is the shipping box labels for the part I received.

According to this website, that 4th character in the prefix is the Design Responsibility Code:
T Heavy Truck Engineering
Z Ford Customer Service Division (Ford), Product Analysis and Publications

Edit: It is interesting that the basic part number (the piece in the middle) says 10C659 on the box but 10C652 on the part. I only glanced at the box my mobile tech had and just saw the -B. Didn't notice the other bits. But it is a later revision as evidenced by the suffix and the SW version.
