"System Off to Save Battery" message

[LocStar320]

Wow, called the local dealer to setup an appointment to get the truck looked at......

11/30/22 8:00am 2.5 months out

Look for a Ford Express service location near you. We have a couple in the Orlando area. No appointment and they take care of routine mnx stuff.

With all the electronics in these new trucks there is a lot more drain on the battery. Maybe Ford should go with a small start battery and a deep cell marine battery for everything else. My boats have ran this type of system for years.

Plenty of room for a much larger battery, once out of warranty, when I need a battery I will find the largest one that will fit.

May be worth resetting the BMS after charging the battery completely.

Not sure how to do that reset.

KEY ON - ENGINE OFF
FLASH HIGH BEAMS 5 TIMES
PRESS AND RELEASE BRAKE PEDAL 3 TIMES
(IF DONE PROPERLY, THE BATTERY ICON WILL FLASH 3 TIMES)

So if I were to keep my truck on a battery tender would it mess with the bms?

No. I would just reset it after your battery is fully charged.

First time my truck has been in the -0 temps. Would this affect the low power mode as well? I drive it everyday and have not had any problems starting it.

I know I got PowerUp 3.5.3 sent to me on Tuesday but it hasn't installed yet and folks who have PTS can't tell me why. This thread goes over my troubleshooting so far. Today I disconnected the battery completely (but left it in the truck) and charged the battery completely until the Noco Genius 10 said fully charged. I then reconnected the battery and performed the BMS reset procedure mentioned earlier in this thread. Now I'm getting the "System Off to save battery" message and the lights shut off immediately and proximity lighting isn't working. I just drove around for 45 minutes and monitored the voltage in Forscan at 15-15.1 volts for pretty much the whole drive, then as soon as I shut if off measured voltage with a multimeter at 12.7 volts. During my drive around town I swung by an O'Reily's and had them test my battery with their tester deal and they said "your battery is good". I was expecting them to say the opposite.

I've been suspicious of my battery being the reason my 3.5.3 OTA hasn't gone through this week and then the readings/behavior of the battery and BMS today thinking the same.

I had never once seen the "system off" message before today.

Any ideas why the system off message/behavior or what I did wrong?

21 have bad batteries.. THey test good but if you Auto Start stop doesn't work most the time your battery is toast. That would cause the Update to stall.. Im surprised no battery warning in oasis.

I don't have Auto Start Stop so don't have any other signs to go off of... would you mind checking my VIN to confirm no battery warning? 1FTFX1E8XMKE93061
