I’m not sure why the truck still starts. Possible LVB issue?

[Biologyinsight]

I received a warning message that a front sensor was not working and may need service. Message never reappeared and truck operates normally. Read on the forums that a low charge on the 12 volt can causes strange error message so I pulled out my multimeter to take a look. Could not get a steady reading from the meter(meter works fine it’s a Fluke). It would jump between 7, 8 and zero volts. AGM is new to me. Should I look onto having the battery replaced? It’s a 2024 Flash. Three months old.

How were you taking the measurement? Even a bad battery won’t jump around like that.

Sounds like the issue is with whatever is holding the meter.

Or bad connection, bad leads, etc.

Yes, it turns out the issues was with the meter, and the one holding it Hooked up to my wife's 12V battery in the VW when she got home. Same strange results. Today I'll try with again with a different meter. Maybe the battery is dying in the Meter? Always something. Thank you all for your help.

Maybe you were on the wrong scale or mode. Make sure the meter is set to read DC volts instead of AC.

I also have a 2024 Flash and have a front sensor that chooses to intermittently have a blocked sensor warning. I also had a LVB issue on a cold day in January where it wouldn't even unlock the doors and I had to use the key for entry and manually open the frunk to jumpstart. I charged the LVB and have had no more issues with the LVB but front parking sensor intermittently shows blocked. Took it into Ford Service and they couldn't find any error codes on the sensors and showed 80% charge on battery but did not indicate actual battery health status. Not very happy with results so I took my truck home and now trolling forum for answers. The saga continues, but I'm still Happy with my Flash and continuing to learn the EV nuances.

I bought this off Amazon. I like to monitor cab temps and see 12V charging status.
