I've recently noticed that every time I start my 2021 Powerboost Platinum the Pro Power system turns itself on. When I turn the truck off, the system remains on even though nothing is plugged in and the covers are securely closed in the bed. I have double checked the outlets and reset the breaker in the bed just for good measure, but nothing changes this behavior. I can see on the FordPass app that it remains on until I go out, turn the truck on and manually turn it off through the display. I could almost swear that I was able to turn it off through the FordPass app originally but that is no longer an option. If I turn it off before shutting the truck off, Pro Power will remain off until the next time I start the truck and then will remain on in low power mode until I manually turn it off again. I suspect this started after the last OTA update a couple of months ago and I also suspect it is helping to drain the battery down slowly resulting in my truck going into sleep mode if I don't drive it daily. Has anyone else experienced this issue and if so have you figured out what is causing it? For the present I will continue to turn the system off every time until the next time I have a reason to take it in to the dealer then have them take a look. I've looked through the manual and the screen options but with so many features, I suppose it is always possible I've overlooked a new setting that causes this system to default to the on position.

ProPower Defaulting On

 

That is normal behavior. You get low power mode that supplies power to the interior receptacles only by default. It only allows minimal power draw (400W?). If you need higher wattage, you need to turn it on. As far as I know, the only way to avoid having it come on would be to have a tripped breaker. What are you trying to accomplish by turning it off? Once the truck is off, the system shuts off. It isn't contributing to your battery draw.

As far as control of the system through the FordPass app, you can only do that when connected to the truck via Bluetooth. Otherwise, you can only see system status and a power usage snapshot.

 

What I'm saying is, it is turning itself on when I start the truck and it DOES NOT turn off when I turn the truck off. Although it isn't being used to power any devices, it is staying on so the truck is using some amount of power to maintain the generator it in a ready state. When I first got the truck and for the first year plus of ownership it did not do this.

 

How do you know it's staying on? I haven't checked, but it is possible it stays on until the power time out of other interior items, which is ~15 min or so. After the truck is off, I wouldn't trust what the app is telling you about ProPower, you should check with a meter or plugging something in to an interior receptacle to verify.

 

I just looked at my Ford Pass app and it's showing the same as yours -- on in low power -- however the update time is when I last drove the vehicle, not current.

I see the update time on your screen shot is 10:39 and your phone time is 10:52, were you driving the truck 15 minutes before you took this screen shot?

 

First thanks to all who are attempting to help me understand my problem. Yes, I checked the FordPass about 15 minutes after shutting the truck off and took that screen shot. I've continued testing and it continues to default on and does not appear to turn off by itself when the truck is turned off. The FordPass does not appear to update beyond when the truck is last turned off but it does consistently report accurately if I did or did not turn off Pro Power before shutting down. Without the FordPass updating over repeated checks I cannot truly confirm or deny that there is some delay between when the truck is turned off and when Pro Power may theoretically shut off due to some timeout. My unscientific test that makes me believe it is drawing power while the truck is not running, is that if I leave the truck as it is with the Pro Power showing that it is active when I turn the truck off, the next morning when I go to start it up the electronics are inactive (screens dark and reporting low power mode on startup) and the truck is in sleep mode. If, however I turn the Pro Power off manually before turning the truck off, when I start the truck the next morning the electronics are all active (screens lit up when I enter the truck) as though the battery has retained more power. Temperatures overnight are consistent and my driving during the day is consistent. The only variable is if I turn off the Pro Power or not.

 

I confirm the same issue on my 2022 PB, SW version is 3.5.2.
This could be a bug in FordPass app (which I find rather unimpressive), but could be a real issue. 400W inverter, even in a low power mode, will still contribute to power drain.
if the weather cooperates, I will try to measure main 12V battery drain with the truck off.
I wondering if it is possible to somehow turn that off (FORD - if you are listening - please make PRO POWER remotely controllable! it would be useful for all intents and purposes!)

 

I'm assuming the Ford App is just reporting the last update that it got from the truck. When the truck is off, it wouldn't make much sense for it to continue to transmit to Ford, chewing up battery since not many things of significance would change while it's off. Curious, have you tried to plug something into a plug (a lamp, radio, whatever) while the truck is running, then turn off the truck and see how long the device stays on for?

 

@sjgreen6 - if you are regularly hitting low power, you might have other, much bigger issue. My PB tried to kill me on the highway - caused by faulty Aux battery insulator, or you might have a bad battery. For your own good, get a DC current clump meter (there are not expensive choices in Amazon), and check what is happening with the main battery after you turn off the truck, locked it (with the hood open so you can still get the current reading), and put away the fob far enough or in a cage so truck does not see the fob. Take measurements in 10, 20, 30 min to see how the battery drain calms down, and what is the final draw.

 

I'll repeat it here again, do not trust what the FordPass app shows for ProPower after the truck is off. Use a voltmeter or multimeter to check the receptacles for voltage, or plug something (low wattage) in before turning the truck off and see how long it stays on. I've only used the interior receptacles a few times, but if I recall correctly, they only had power if the ignition was on. As soon as the ignition was off, they were dead. If you're having battery issues, constantly refreshing data in FordPass is only going to make it worse, regardless of what you think is happening with your ProPower system.
