If you have deep sleep issues, try a BMS reset

[Stock411]

Try reset your BMS. I had this issue when I installed a aftermarket subwoofer and the remote turn on wasn’t wired properly so the subwoofer stayed on for almost 5 minutes before it “auto shut off”. The issue was fixed but the battery drain remained. I knew if I took it to the dealer they’ll automatically look at the subwoofer and claim it’s fault.

I kept getting FordPass notifications daily about the truck entering deep sleep mode, no dome lights or remote starting. Unresponsive from FordPass App..

I did the BMS reset presented here and no more issues for over 2 weeks now. Worked for me, might work for you and save a trip to the dealership.

Important to know. The dealership replaced first year weak battery with a new battery when used as a trade-in that fell-through. So got my trade back with new battery, they also corrected a few other nagging issues while in their temporary ownership.
But think they didn’t reset BMS. I charged the new battery after it flatlined a week after getting it back, then reset the BMS haven’t had an issue for a whole month!

I started receiving the Deep Sleep issue about five months after receiving my 2023 Maverick. It's very frustrating. This BMS reset does work (for a day) for me. Now I will try to remember to reset once a day. The video seems to be a little different from what I have to do to reset on my Maverick. When I turn the key to On and click the High Beam five times, then step on Brake three times, my Battery icon does not Flash. I have to turn the key Off and then back on and then the Battery icon will flash several times. Then I turn the key Off and I'm set.....for a day. You explain this in your video but when you do the demonstration, you don't turn it off after you do the brake three times. This may be confusing the people who follow your video. Thanks for the video.
