IPMA update July 2024

[G-Zeus]

Decided to run through some updates before a road trip, hoping to get some of those BlueCruise enhancements… be warned, this IPMA update is a doozy, should be at least 2.5 hours. I hit hour 3, finally getting through the updates and taking forever to run through the module configuration. And the car was making awful electronic pulsing noises at times. Found this on the MachE forum, thanks to Mike G last night for posting it.

I followed his instructions, shut down FDRS, etc. Truck took some time to settle down, but restarting the IMPA update only took another minute to complete. Now on the the other updates…

DSM update… 1817 blocks to write! Going relatively quickly though.

DDM said it failed but after clearing DTCs in Forscan, it shows up as green. Weird.

Well DDM also failed. I’m going to chalk this up to a LVB that has been stressed for the last 3 hours, despite being on a charger. Going to let it recover for a bit and try the other updates again. Right now the truck is not pleased…

What was the reason it failed? What did FDRS say?

I’m all good now. After letting the LVB charge up, I reran the DDM update and reset the DSM configuration. All other updates completed without issues, DTC’s are cleared and no more errors showing up. Only the BSM update remains, but the dealer is going to have to do that one with their password.

They won't need a password to do it, but glad to hear every thing went smoothly.

So if anyone wants if instructions on how not to do this update:
(alternate title: How to brick your Lightning in two easy steps!)

1) Be absolutely sure that you do not have the properly sized battery charger/maintainer or read other posts about this process and understand them prior to starting this three hour marathon.(6 to 8 hours if you follow these directions.)
2) Start update

FYI-it was, however, a good (but painful)learning experience!
(also in hindsight, it was pretty cool seeing every possible alert on the truck go off when you restart it)

I was going to do this one last, but somehow hit it by accident.
You can recover with a lot of fortitude and patience!
Luckily(after waiting 15-30 minutes for it to finish configuring)I got on here and did a search and found this post and @MikeG post on restarting and completing it!
The other 12 or so updates took one to two hours!

So I just performed this update and now I have the following DTC for SCCM:

U023A = Lost Communication with Image Processor Module "A"

What should I do to fix this? I cleared DTCs but it comes right back.

Nothing you can do about that for now. Just ignore it.
