Update on SSM-53801

[Glen Baker LLC]

Yes, I pulled fuse 11/12
I don't use Ford pass or remote start.
Don't forget your new jump pack, just in case. Enjoy vacation.

Ok thx for confirming that! Jump pack already packed although girlfriend may insist on taking her old Hyundai because she doesn't trust my maverick anymore LOL.

Well I fully charged the battery and did a BMS reset and let it sit for 10 hours with doors locked. Worked great yesterday. Woke up this morning to a deep sleep mode message. I'll go see if it starts when I leave for work. Ugh. Ford needs to fix this! Guess I may be testing out my new battery booster this am.

If that was thru the night, not on initial close of door and lock - then only a couple of things.

Bad battery as mentioned. It can happen, new battery off the shelf - happens to be bad, can't hold a charge.

Or you really do have a parasitic drain that struck and lowered voltage enough to kick off DSM.
But if that's the case - it should be back at next turnoff, and may be a drained battery.
While you had this SSM for ACCM update done, and this appears to be what Ford thinks is the big drain - there have been others. Actually I never saw a post where the ACCM was the reason - 3 posts shared other modules, 2 of them were the TCU.

Actually - 3rd option.
The SOC update comes at the end of the Relearn, that's what it's doing, before that updated value is known & used, you were on the verge of a reading too low, and that happened during the Relearn, so it went to DSM.
In which case no big deal. It's why the relearn is important.

Of note the truck did start. I did put a winter tire package on a few weeks ago with no tpms sensors so it gives an error message and interestingly 48 hours after that was when I started getting the dead battery issue. Wonder if that error message is somehow causing an ongoing glitch and drain. Maybe I should pull fuse 11?

Interesting - truck wants to receive data from the TPMS sensors, and it should be programmed that those wake up on movement, so don't leave that radio on expecting to receive anything - when the truck has been parked and turned off.

But like any computer glitch - it could be accidentally kept on waiting to receive all night long.

Fuse 11 is just for the modem, not other radios, so that wouldn't have an effect.

Doesn't seem to have an effect
Measuring 12.3v this am
Was 12.6v last night.
