LVB issues - Deep Sleep Mode

[AT193]

I know the LVB and associated issues have been brought up a lot on the forum. I just wanted to throw in some weirdness that I'm experiencing as well. Starting about three days ago I noticed that the FordPass app would often not be able to remote start, lock, unlock, or at all control the truck. It was also missing a lot of driving records and wouldn't update the location, unless I manually got into the truck and turned it on. Then I was away from the truck for 24 hours and it went into "Deep Sleep Mode" and threw a big red warning in the app. When I got back I noticed it not lightning up on approach, and the easy unlock by sliding hand behind the handle was not working. FOB still worked to unlock. When I got in the truck nothing happened on the screens like it usually does and I had to start the truck in order for it to even know I was there.

Based on my reading online this all seemed related to the LVB, so I called the dealer and brought it in. They tested the 12v battery thoroughly and said that it came back fine. I am the first F150L that they are servicing in any way, so they are doing some more research on their own and getting back to me.

Does anyone else have insight into this? If the LVB is coming back okay, maybe the truck just thinks it's low for some reason? None of this was happening before the last 3.3.1 update, so maybe it's related to that?

Following up: Dealer says that this is related to all of the updates that have happened. Apparently the truck may throw itself into deep sleep mode and have this issues if there has been an update. They are resetting the BMS and some other systems and said that I should be good to go. We'll see!

The saga continues: I haven't had any further issues with the Deep Sleep Mode or LVB. However I'm still having the same issues with Fordpass. Basically none of the remote commands work at all. They just time out and nothing happens. Additionally It will not refresh the information from the truck, which is very frustrating since I can't track charging, or anything else. After researching I've gone through every step of rebooting, reinstalling, reactivating, reinserting, reinspecting, and rereading that I could find. I know other people are having issues with Fordpass so I wanted to share some info that I got from Ford below.

It seems like some of it is the app itself (no surprise) and will be "corrected" with the next app update. The other issues are somehow linked to the modem in the truck, so I will be going back to the dealership tomorrow morning with a specific code (SSM-50829) for them to address this issue.

Only once have I come up to my truck and had it not auto-unlock when I reach inside the handle. I had to use the fob like you. The screens seemed normal from what I remember, but I had no navigation for that trip. It just wouldn't load, and I couldn't tell it to navigate anywhere via voice prompts. It simply said navigation wasn't available. I used ABRP to navigate back.

This happened this past weekend, but it was after only a couple hours of sitting in a parking lot. I'd chalk this it up as a fluke and not something failing, though it is annoying.

The app hasn't been great for me either, and some commands have failed, but it works more than it fails.

Hi, Im having the same issues. Did you go to the dealer and what did they find?

I just had this issue as well. When I came home from our ~40 mile trip, I plugged in the truck and it didn't charge since I was above the 90% charge threshold. Later on that night I checked, and it was in Deep Sleep Mode as per the application. I didn't think of it, and went out to the truck today to go to work. As others have pointed out, only the KeyFOB would work and when I started the vehicle it gave me a audible warning (like something was left on). I then drove to drop off my son to school, and I went to work. While at work, I went to the FordApp, and it appears that all is well.

Had an issue today with deep sleep mode. 3 weeks owned, about 1300 miles. Received 3.5.4 at some point today (12/7). Headed to a shop to get retrax installed this morning , left with 80%. Drove there waited 1.5 hours cover installed and headed home. Popped back on charger to top off to 80%. Left in the afternoon with 80% for a 56 mile commute. Checked FordPass a couple hours later and I got “your vehicle is in deep sleep mode and connectivity is temporarily unavailable. Manually turn on your vehicle to” (it’s like it ran out of room to finish the warning). Temps today were in the low to mid 50s.

I was nervous I was going to be stuck an hour away from home. Got in and thankfully she turned on and was able to do the 56 mile trip home. Charging right now and no deep sleep notification in FordPass.

any recommendations? Maybe just a glitch?

My ICE f250 (build after July 22) had it. It’s a code that can fixed in less than an hour at the dealership. They should know what you are talking about if you tell them you keep getting repeat messages of sleep mode. I want to say the update is called OASIS on the ice vehicles

OASIS is the Ford system that tells by VIN what’s applicable from a service and recall standpoint.

Got it. Thanks. All I know is I went in there and told them and they knew what it was about and an hour later they fixed it and haven’t had the sleep mode come back on
