Lightning Software Updates using FDRS

[Mike G]

2 Mar 25 and there's a complete set of powertrain updates out for my '22 Lariat ER today. I was holding off updating the door modules that came out last week until something more substantive came along. I guess this is it.

I checked two '23 models and they don't have these updates.
I checked two '24 models but they do have them.

Maybe they're still working on the validation for the '23 model versions (that's happened before with other updates).

I didn't get a chance to post the followup to my 2 March powertrain and doors update due to issues with my account that started on the 3rd and were only resolved yesterday.

Here's how that went:

The powertrain script started at 2:39 when I selected the PCM and hit "Run". Right side column is how long each module took according to FDRS.

PCM	2:39​	0:02​
ABS	2:41​	0:03​
SOBDMB	2:44​	0:04​
SOBDMC	2:48​	0:03​
SOBDM	2:51​	0:02​
BECM	2:53​	0:02​
GFM2	2:55​	0:02​
Powertrain scripted update end	2:57​

Total time for all powertrain module updates was 18 minutes.
Both door modules took 4 minutes each.

I saw folks posting about the OTA gateway update (ECG-25.2.5.7.1), and even though it is in my OTA queue right now, it has not started downloading yet...and had what looked like a scheduled install date of the 13th of March for my truck. So I just did it with FDRS instead yesterday.

I see you tried the ACM and RFA again. I assume those didn’t work.

So FDRS showed you had both the ECG OTA and also a GWM update available? Did the OTA go away when you updated the GWM?

Is your GWM now -RCP?

My 2022 Lightning hasn't updated since September so I just bought a Mongoose, for others FYI I live in Conyers GA and if you have issues shoot me a PM and I can try and help you as well. I'll have my Mongoose and start updates tomorrow, looks fairly easy if you have experience with tuning cars or using Forscan. Pricey module for sure but the dealer has failed twice when we asked them to do the updates.
