A new BCM updated popped for my Job 1 in FDRS this morning. Could this be @Jimrpa 's frunk button?

TEST TEST TEST!

Did you do the OBCC update that that popped up over the weekend? People are saying it’s an old version, not sure if safe to do both updates.

I have not done either of those yet.

The OBCC is a -AM version (from the previous -AN) and would appear to be a reversion but I believe, just like in the Lightning's case with that OBCC update this past weekend some DIDs were updated, and some were rolled back.

As an example, attached is what changed on the Lightning (vs. our dealer's mannequin as a reference)

On the BCM update from this morning. There is still no frunk button for those who are wondering but there is a "Service Frunk" message that pops up on startup now and has to be acknowledged. I have a Job 1 with just a manual frunk opening lever so not sure what needs servicing unless its something to do with the latch. The frunk opens and closes and latches normally as it did before the BCM update. And there are no DTCs at all. So. A bit of a mystery. The version it updates to for my '21 Job 1 is MU5T-14C184-ACR.

I've done a BCM config already (2x) and a LIN procedure as well with no changes.

Oh, and I don't use or have PAAK enabled.

OBCC is a downgrade. I'm hoping to receive information today about what issues there may have been with the newer version.

I flashed both OBCC and BCM on my '21 GTPE. No issues or perceivable changes.

So you didn't have the open frunk warnings like Mike?

No. Just the typical TPMS after a BCM update which cleared after about a minute of driving.

Do you have a working frunk software button?

Do you have a working frunk software button?

It's a Job 2 so I have always had the software frunk release. Still working fine on SYNC, keypad, and FordPass after BCM update.

I wonder if that's the difference. I have no software button at all. And I don't use PAAK.

Interesting to see this after my OBCC was updated today, apparently there was a error code that prompted this install, but it’s not anything I’ve seen on the IPC.

So it's a reversion to the previous software package? As in they recalled the -AN software and FDRS puts -AM back on now?

Correct. -AN is replaced with -AM. @Mike G mentioned here that in the Lightning forums someone posted a comparison which shows that some data identifiers reverted to -AM versions, while some stayed at the -AN versions.

Correction: The comparison was made by Mike.
