Deep Sleep (4 questions)

Deep Sleep (4 questions)

Ford.com says deep sleep is enacted by one of the following
-vehicle inactivity for 14 consecutive days
-voltage drops below 9.5
-extremely cold/hot weather conditions

Question #1
If you turn off connectivity via the center console screen or pull the fuse, does the trucklette go into a deep sleep?
(interior lights, 3rd light reverse, or light in bed of truck -- not working safety hazard)

=====
Question #2
Is there a way thru ForScan to change the temp setting for extreme cold/hot temp conditions enacting deep sleep??

=====
Question #3
The FordPass App and manual say to drive the trucklette after going into deep sleep mode, what truly happens when you drive??
-----
-->does driving in sport mode (keeping engine on often - not electric) or using the "L" button to deep charge in green on the odometer help charge the 12v battery faster??
OR
-->is it just required to drive in any mode for many minutes with high voltage battery/circuitry like trickle charging the 12v ??

=====
Question #4
How do you manually remove the trucklette from deep sleep mode ?? (I wish there was a deep sleep button like drive mode)
Battery Sensor Reset -- only way ??
1.Switch ignition "On" (leave engine off)
2. Flash high beam 5x (ending on with high beams off)
3. Brake pedal 3x
(step 2 & 3 within 10 seconds)

3 and 4 are related.

you start and drive the truck at least 20 minutes of moving time. since it's a hybrid, you can't manually control autostop/start and if you're sitting for 15 min in traffic or a parking lot, obviously that's not driving. the gas engine has to run to charge the HV battery, which then charges the 12V battery. you can force the gas engine to run by selecting max heat. you can encourage it to run more often by choosing sport drive mode.

since you have a hybrid you might want to buy a battery tender and/or replace the factory battery with an AGM. there are tons of threads about both, and there is actually a Ford/Motorcraft AGM hybrid battery now, if you want oem for some reason.

I have no idea what you're trying to ask in #2 or why you think that would make a difference.

#1 there is an open recall on hybrid parasitic drain and there is no remedy available but apparently it will be a software fix (reflash) when available. people have tried pulling the telematics fuse and they still have battery drain issues.

Deep sleep is when the modem is disabled - hence getting a final warning that it is occurring and no remote features available.
Add below 50% SOC also. But I'm sensing this is for a period of time, because I've remote started with 48% SOC which didn't remain there for long.

Battery saver functions is the other stuff occurring at various levels of annoyance.
That has it's own set of Volts where things start shortening their time on, until reaching a point they don't stay on. Several have reported what those values are in Forscan - can't recall anyone changing them.

#1 - So it's not really possible to go into deep sleep if you already disabled it, by the fuse - you beat it to the punch.
Now, fuse left but you getting Fordpass app disabled and unlinked doesn't stop truck from reporting up info to Ford, which is usually after you park or after startup, not like constantly thru 14 days of sitting there unused, if there is no ability to remote start it, no need to remain connected. I'm sure at some point it'll report up to Ford that it's disabling the modem if needed, so they have it known they won't be able to reach the truck either if they are asked to check on something like location.

#2 - There was a recall that pointed out the 4 requirements for deep sleep - temps wasn't one of them. But obviously temp can effect Volt reading and SOC%, so probably in that way it matters. So no setting to change that any have found. Never heard of someone attempting to adjust the other parameters for battery saver functions.
If raised higher so sooner deep sleep or battery saver, that would protect the battery more. If lowered so push deep sleep off, might mean not enough battery to start when you finally attempt to.

#3 - For hybrid - you can frankly just sit in driveway with truck started. Engine will come on when required to charge the HVB back up to 40%, which feeds the 12VB when the engine is not running (down to 30%).
But sadly you only get decent Amps for maybe mere minutes, then it's down to 3-4 Amps for mere minutes more, than down to trickle charge 1 or below Amps.
Actually driving changes nothing regarding that, except giving a lot of time for a trickle charge. If you have ever charged a battery with a trickle-only charger - you know how long that might take to bring it up to decent voltage.
That's part of issue - BMS charging logic. And poor quality batteries that suffer more from it.
External charger much better idea.
I've not tested what is the minimal time required to turn off truck, do an errand, come back and start up and get decent Amps for some minutes again. I know sitting in driveway and going off/on within a couple minutes doesn't fool the BMS system (it goes right back to 1 or less Amps), but doing a bunch of short errands with maybe 10-15 min stops does work.

#4 - do NOT do a BS reset, except for when the manual says to do it - with a new fully charged battery. Otherwise you are just forcing a problem to be worse to crash sooner.
If a truck function is trying to preserve the battery so it can be manually started next time and then be charged up - why would you want to remove that function and have the issue it's trying to protect you from?
Not only might remote start not work anyway if battery ends up too drained, but then you can't manually start it either. Obviously in theory there is some gap in time where it would still work, but in practice you won't really know.

Now that you created this thread - the 5 similar threads shown below will provide plenty of reading on it, incase you've missed the fun of all the other reporting.

If you are getting the deep sleep warning almost immediately on parking - your battery may indeed not be able to keep a charge.
Time to go get it fully tested at dealer - do request a full test.
Which is a load test at minimum.
Many have found that is when their battery is discovered to have a bad cell or just so poorly performing they do get a warranty replacement.
But if not - just wait with aggravation - it'll get there.

Oh - since there is an SSM for service department regarding complete battery drain issues (yours isn't that) - don't let them tell you a software fix is coming and do nothing.
If they want to lump it under those instructions - then they need to first do the full charge and test contained in them.

The feature is built into the truck to protect your 12 volt battery. So you won't have a dead one when you come back to it later after it sits for a while.

If you want to disable something, pull fuse 11 and disconnect the stupid modem in the truck.

Thx guys -- i may pull the fuse

My WTH things are mine appears to not like NorthEast cold (is it measuring temp is my wondering -- that is where my mind jumped to a forscan setting possibility)

I have been driving 5x a week yet it still alerts the app in deep sleep and I lose lighting and app auto start

New battery was done by dealership like 6 months ago

My self installed AGM will start and provide dome/courtesy lights with a 39% SOC after sitting in <10 degree northeast weather for a few days. The AGM is a champ in cold weather with deep discharge. AGM in the Hybrid is a peace of mind necessity.

What battery (make/model) did you buy, please?
Pics?

Some people who've bought an AGM battery are still having their trucks go into battery saver mode. Seems to delay the problems caused by the BMS software not keeping the 12v battery fully charged. Ford supposedly has a BMS fix coming soon.

In the mean time, one way to prevent battery saver mode for those having it, seems to be periodically connecting their truck to a battery maintainer.
