Remotely Accessing LV Battery Voltage from Ford.com with Chrome

Given that Ford removed access to LVB voltage I thought it might be useful to write this up for Chrome. Thanks to Lars/Holy Driver for giving this procedure in Firefox. I don't have Firefox but the procedure is probably pretty similar: https://www.macheforum.com/site/thr...de-the-car-dead-12v-battery.41505/post-893115 .

See Mach-Lee's 12V FAQ https://www.macheforum.com/site/threads/12v-battery-faq.32744/ for all the caveats around randomly reading the voltage of the LVB. Unless Ford changes the software for the LVB charging regime I highly recommend preemptively putting in a new LVB around 3 years.

This gives you the voltage when last connected to the Ford server. If the car is on or is charging it will show the 15V or so charge voltage. I found that an unlock/lock in the FordPass app will refresh the voltage state. Note that some systems in the car will be active when reading the state so the voltage level will be under a slight load and won’t be the same as an open circuit reading. My new battery reads 12.1V to 13.4V depending on the load and charge state. I don’t know if the LV battery health is available. Perhaps that’s what the entry Oil Health means ? ?

In Chrome:

1. Go to https://www.ford.com/
2. Type the F12 Key to open developer toolbox
3. Select Network and Fetch/XHR (might have to poke around for these but they will stay selected next time toolbox is opened)
4. On ford.com login at the upper right corner person icon
5. Again in the upper right person icon select your_user_name account
6. On ford.com under your VIN select Go To Vehicle
7. In the developer toolbox select the Name heading so the list will sort alphabetically.
8. Scroll down to S’ and select status?countryCode=us
9. You might have to select Preview
10. Open up vehiclestatus
11. Open up battery
12. Magically you get: batteryStatusActual: {value: "12.4375", status: null, timestamp: "2025-01-11 15:22:21Z"}

Timestamp is in Zulu or GMT. Let me know if I made any errors in the procedure.

Edit: The FordPass unlock/lock status refresh can be done anytime before selecting Go To Vehicle but you might have to wait for the server to update. To get another refresh you may need to go back to the login step because of cache effects.

I’m new to the Mach-e world (used 2021 Sel SR AWD job 2, iconic silver) and want to thank everyone on the forum for all the helpful posts. I installed the Torklift EchoHitch and wiring harness. Also added 2.5” hole plugs over the LVB jump points. The 2.5” (-) hole also has room to access the HVB cutoff. I preemptively replaced the LVB at 3 years because the car sat on the dealer lot for 4 or 5 months and the LVB was also likely chronically under-charged by the previous owner’s low usage.

Oops, guess I should have posted in Charging, Battery, 12v, Electrical category. Anyone know how to move a thread?

As a previous long ago mod, (far far away) mods do have that ability if you request.

nice write up

On safari, you can access this in Develop > Show Web Inspector (you might need to turn on the developer menu in the safari preferences though). after following the steps to get to the car's page on ford, com, you can se the battery status in a similar place; select the network tab, sort by the Name field, find and click "status" and then scroll or search (command-F) for batteryStatusActual.

I tried it and it works. One tip that helps is to refresh the vehicle status in FP before doing the stuff in Chrome. I found that if I did it afterwards and then refreshed the Chrome page to get the latest, only a tiny subset of records show up in the developer panel. (This could 100% be operator error - I am very far from an expert.)

It would be great if someone could find a way to extract this info without need to get into the developer panel!

Yes, thanks, do the FordPass refresh before selecting Go To Vehicle. Because of cache effects you might have to start over at login if you want an update. I'm sure there is someone out there that can write a script to grab the status.

Great resource. Does it work with Firefox?

 

[Stanmckinney]

I don’t understand all this stuff and probably couldn’t do it if I did. Why can’t Ford just provide a simple way to monitor the battery?

i'm sure it does, the instructions are probably pretty similar to chrome. as mentioned i was able to find it using safari, so it's not a chrome-specific thing.

I wonder the same thing too. They just want to keep us all in the dark as much as they can.

my guess is that they think it will cause more confusion and concern than it's worth. also the battery voltage alone isn't really enough to go on, you probably also want the SOC and that doesn't seem to be available on the backend (but that doesn't mean the car doesn't send it to the server). not sure if the 12V has a SOH in OBD2 but i'd think that's what you'd really want to see.

I went to my car's page on the Ford website and pulled up my vehicle dashboard. Even after doing so, I could not find the "status" field under "Name". Am I missing something?

There has been other threads where some users just never had that show up in their developer tab and never found any reason for that.

Also Ford occasionally hides this data or makes a change where it won't show up occasionally but it has always come back eventually.

Hmm, if after selecting Go To Vehicle the page was somehow refreshed again the status will disappear? It's only loaded once after Go To Vehicle. Close the page and try starting from the beginning following the steps in order. Not sure otherwise. I did try it on two computers.
