What is this on screen Notice?

[SuperDave150]

I track all vehicle stats provided by FordPass via third party software for my smart home and its common to see the Bronco drop down to about ~12v when sitting for a while, but the truck will start disabling "always on" sensors and systems to drop battery usage drastically once you get to the point of seeing the error message in question.

You have to translate percentages to voltage to understand my chart.. This is from Dec 1 to 31st. My smart home automatically does the translation for me but it doesn't show up in the graph.

100% is ~14v, about 75% is the sweet spot (12.25V). I do not drive the Bronco much as it is a second vehicle and you can see that in the chart.

FYI, the really high readings are from FordPass reporting the voltage coming off the alternator while running. Normal range is about 13.8v to 11.9v before my Bronco will go into long term sleep mode..

This is where it's sitting today after not driving it since last weekend.. You can see the voltage does drop over time.

I hope this data helps some how. Just thought I'd share what I've collected.

@Theherofails Could that app (or any other) be used to monitor voltage in real time while flat towing?

Other options could, yes. Not the implementation I have as FordPass does not operate in real time - it gets triggered by certain events such as engine on, engine off, doors opening etc. I use an automation to trigger fresh statistics once a day since I drive it so rarely and it'll go into deep sleep mode and stop reporting.

You'll want to use a third party device hooked to the battery past the battery sensor device.

You'll want to do due diligence before ordering, but you're looking for a device like this that can report voltage in real time and allow you to set alarms.

Superb. Thank you @Theherofails !

Now if we could just figure out a way to independently verify & monitor which mode the transfer case is in (2H/4A/4H/4L/Neutral).

For those viewing this thread in the future facing the same issue. Drive it to charge it up, If the screen continues to display this message when you turn the bronco off even after a long drive. Try resetting the battery management system by turning accessory mode on (engine off), then Flashing the high beams 5 times, then pressing the break pedal 3 times. Wait a few seconds to a minute and you will see the red battery icon flash on your dash which indicates you have successfully reset the system. After this, it shouldn’t continue to display that message when you power off.

This worked for me! Thanks. My interior lights weren’t turning on when opening door with engine off. Then I saw the battery save message. The above worked in fixing it.
