Low battery warning message received in app!

[TedTX]

Well the truck going to get some gas with my freshly charged jump pack in the back seat. Left on the street away from the house so Ford can tow the piece of crap Truck after Christmas to at least replace the always badish battery.

Utter disaster! The freshly charged battery yesterday and now showing 11.7v battery protection mode activated so can’t even flash my highbeems to begin the BMS reset process.
That is such a stupid design. The battery is toast, BMS is confused and can’t be reset. Truck is on its death throws and a massive deep cold blast should finish 12v battery off. Merry frick’n Christmas thanks Ford for the gift that keeps taking my time and efforts.

My truck is presently in 'protection mode', no interior lights when opening doors. 11.9VDC across underhood pins.

Only my Low beam lights will come on / flash when stalk pulled w/o key in.

Inserting key, turning to 'run', pulling stalk will flash high beam lights. Consistant with page 311 of manual

good luck...

I know the feeling, thank you Ford!

Yes but you can’t trigger the battery reset toggle in that mode you only in accessary mode.
I wasn’t trying to activate the highbeems for that reason. But to reset BMS. Not possible in protected mode.

Well, good news 10yo Prius on its second 12v battery was only 12.3v low and taking the charge like a champ. Tires were low so got to try my air compressor in the handy 12v jump pack I got for the Maverick. Worked much better than it should for a old designed jump pack. Turns out it was built in Vietnam and not China, that was a surprise.

Family says it’s snowing in Dallas area. Front has yet reached us. In my Ford Maverick T-Shirt and feeling some what hot.

I ordered my XL (Hybrid) in June, 2021, took delivery in March, 2022. I started having the Deep Sleep Mode alerts about November, 2022. One dealer could not find any issues. Another dealer took the time, made the effort, and found the solution - at least for my truck's problem. For my truck, the Telematics Control Unit failed. The dealer discovered this by first checking with Ford engineers, then trying to flash an update to the TCU - which failed. They replaced the TCU, reprogrammed it, and, so far, all is working properly - with no Deep Sleep Mode alerts.

I, and many other owners, have had similar issues with the hybrids, and even some have reported the issues with the 2.0. See my thread entitled My Experience With Deep Sleep Mode Messages. So far, I have not been provided a solution and I haven't read that anyone else has. Some think that we are experiencing the early symptoms of a wiring harness complete failure, at which time Ford will apparently deal with the issue. I will add that the "longer drive solution" has not worked for me as I have often received the message shortly after taking a 20 mile drive.

I too received the same FordPass message REMOTE FEATURES DISABLED TO PRESERVE BATTERY on my 2022 XL ECOBOOST with 29K miles. This was after driving 35 mile to work so it was not from not being driven. It also reset my check engine light that had been on for at least 2 months waiting for a replacement fuel tank pressure sensor. Odd that was the morning before my service appointment to replace the sensor and now no CEL is displayed. The current PO496 and PO451 are still stored but no light. Did my truck lose power and reset?

I drive often enough and yesterday I drove for over an hour. 3 hours after I got back my Ford App had warning notification my maverick went into Deep Sleep mode. Weird. This Hybrid is only 1 1/2 years old and has 18,000 miles on it. Absolutely no reason for it to do that. Truck is garage kept and never had any long term exposure to very cold conditions. Is there anywhere inside the truck menu systems I can verify this message or check the battery voltage? Thank you.

No system check - multimeter under the seat in the morning after opening door, prep the area the night before to do it fast.

Since it's garaged - does it get locked overnight?

That DSM engagement is based on 3 things, one being the calculated SOC%.

After a 1 hr drive it obviously got charged up like normal. (is that 2x daily 1 hr drive?)
But unless it was the night that it was going to do a BMS Relearn, that SOC% value isn't going to be updated.
So it may think it's still low.

And if you don't lock the truck for 9 hrs - it'll never do a BMS Relearn.

So do a morning voltage check.
And yes, it can be very common for many of us to have a battery not making it 2 years - should check out the forum posts - they are multiple and frequent.

If that checks out well below 12.0 V, you may have had a singular incident of a parasitic drain.
Something didn't turn off either during the 75 min going to sleep time, or still didn't turn off in sleep mode time after, and voltage kept dropping so low (below 9.5V) that the DSM was kicked on to help preserve the battery.

So you won't know exactly - but you can get an idea.
The inaccurate SOC% because of not locking doors at night, that's an easy one and your battery likely has no true problem except age, and the fact they seem to be undercharged anyway for many of us.

If the voltage is really low - it may have been an actual drain that happened, maybe just during the 75 min, and then sleep mode turned off whatever (light?) was on, and battery recovered a bit.
Happen to have the AC on when you stopped on this trip - compared to not used so much this year yet?

Either way, 2 yr old battery in the hybrid - don't be expecting 6 years from it.
Wouldn't be unusual to be near end of life - especially if it did get a drain event. Not good on an old battery.

Thank you. I will get something (volt meter) to check the battery. I have not been in AC mode for quite a while. I never lock the truck in my garage. I will tonight and start checking the volts on the battery Thanks again...Tony

i got the same message last week. I was also concerned that it might be the battery harness issue. i drove for about 5 minutes and the message went away. i took it to the dealer on a thursday evening. they couldn't get to my truck until monday. it's monday now they weren't able to find anything wrong. they reported it on the TSB. a few takeaways that i've gathered from my own experience:

--seeing as the truck sat on their lot from thursday evening to monday, the battery was fine. so that's a good sign for me i suppose....

--one member pointed out, when the key fob is near the truck, there's a lot or relays that get activated and you hear all sorts of clicking going on. when you got the battery message, did you notice if you were getting in and out of the vehicle a lot? where do you store your FOB? would it be near the truck and just close enough in range that activates the truck with all that clicking that it does? i'm not saying that this is the cause but just another point of view or perspective to wonder about.

i will continue to monitor to see if it occurs again.

Maybe the sale team drove your Maverick to lunch everyday they had it - check for fries in between the front seats?

My Tremor does this ALL the time. Stealer blames me without and specific explaination or remedy.

Good day

This is in addition to all the good info @HeyBales already passed on.

If you do a Battery relearn procedure, you first need to get a smart battery charger that provides at least 4-5 amps (as well as a decent multimeter to do all your testing) that can charge whatever battery you have installed in your truck (probably a wet cell, if I am guessing) to it's maximum capability.

So this is what I do every month or two.
-I have a garage, so I park inside and pop the hood. -We have battery attachment points in our engine bays, so I use them. Much easier access but you can certainly access the battery under the seat if you wish.
-I charge the battery till it is fully charged. Charge time varies according to the batteries discharge level and also it's health...(a good smart charger can possibly recondition/put some life back into it but they aren't miracle workers.)
-once the battery is confirmed to be good and fully charged (and after making sure all electrical loads are removed, such as dash cam, digital readout, or USB flashlights for example), disconnect the charger, close the engine bonnet, make sure all doors are closed as well and then lock up the truck and leave it for 9 or 10 hours.

Keep all your keys/truck fobs stored away from the truck and don't touch them, (and don't go back in the truck...if you do then you need to restart the process).

This is where you now leave the truck completely alone...for 9 or 10 hours.

This time is required for the truck to relearn what a fully charged battery looks like and so that it will charge it to this new level from this point forward.

This sounds like a lot of work, but it really isn't once you do it once or twice.

Depending on your battery health a new battery may be required. I would suggest an H4 AGM battery which is what your trucks charging system thinks it has.

Good luck,

Andy
