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

[Mike G]

Am I going crazy? This CSP appeared yesterday in Ford Pass. And today it is missing? My truck was plugged in and charging over night, wonder if that alleviated the triggering condition for the CSP?

Have you tried here?

Ah nevermind I don't see it in there...but there's a lot of other stuff....

And that CSP is still active for me in my owner site (along with the rear light bar).

Many dealerships have two at most. Putting them on the road means they aren't working on an EV.

What the dealers could do is put a junior tech out on the road, to do the simple tasks, ie. like the grease monkeys (Oil Change Tech) give them entry level training to do these basic services.

Mines still listed on the Fordpass app and by the web-page https://www.ford.com/support/recalls-details/

Thanks. I have to bookmark this. The CSP appears here with my VIN, but it's still missing from my phone app.

Hopefully, it will fix this, too ... but this is more likely to be a software issue ...

Nope, but you can see more accurate information about the LVB SOC and the trucks estimated range here https://www.ford.com/myaccount/account-dashboard

Well guess I can stop trying to get updates everyday

Just so I understand, this part - if defective - would stop updates from installing due to the misreporting of the 12 volt battery charge level. As in during that actual installation of the update. However, for those of us that have never received an update yet, this is for future proofing when we eventually do?

If you have this part, you should get it replaced as it will cause difficulty in getting OTA in the future, that is correct

To be more specific, there are two things here that are constantly confused:
1) Ford sends you an OTA update and usually alerts you if one has been downloaded and that it will install at your next scheduled time (or you can choose to install now)
2) Either at the next scheduled time (or Install now), the updates fails with a message that the update was interrupted by another process. But folks can look up the actual failure message for you and it's almost always related to the 12V battery.

This part WILL NOT fix number 1. If you aren't getting updates sent to you it's because your vehicle is not in the queue for the update. Appears to a lot of 2023's. It's not due to this part.

If you are getting updates sent to you but they fail because it was interrupted, then the part may fix that. TBD.

OTA's have not started being pushed to late build 23MY trucks yet. It's not due to this part or any part.

Correct. Won't help you get the update sent to you. But once it is sent, may give it a better chance to install.

I would think that you don't need to be EV-certified to replace a dashmat or lightbar or even do a FDRS update. I didn't ask the mobile tech that was here if he was EV-certified but will ask next time. Could be dealer specific within certain guidelines by Ford.

Hey if you buy the part yourself would you send me the old one instead of throwing it away? I love looking inside these things. The 14thGen forum has a BMS thread over 50 pages long (they are having a different set of 12V issues). Looks like the sensor might have a Hall Effect sensor or shunt along with a thermistor for temp. Appears to send this info to the BCM via the LIN bus. What I haven't found out is if sends the raw values (voltage, current, and temp) and the BCM calculates SOC, or if the BMS itself calculates the SOC. It must be the latter if they think the SOC issue is fixed with a new BMS. Supposedly it has a small microcontroller inside and that's what I want to look at. But the answer may also be in the 59 pages of that thread (I am only on page 3 )

EDIT: I am going to ask to keep the part when they come replace it but I know they typically aren't allowed to do that for warranty work.

FWIW, I have the defect part and only failed during one of the updates. The rest went through flawlessly.

Those that bemoan the lack of mobile service for EVs don't get the shortage of EV techs. My dealership has ONE. Many dealerships have two at most. Putting them on the road means they aren't working on an EV.

Yes! Absolutely! The dealerships can offer alternatives that make customers' lives easier. They can offer Lyft rides from and back to dealerships. They can also offer to pick-up your vehicle. Mine does both.
