I guess we need a comprehensive list of all the acronyms and their functions?!

here is a list of the modules on a 24 Lightning

But The SOBDMB and C are the Motor controllers.
Sobdm A On Board Primary Charger
GFM3 7.2 Inverter
GFM2 Second On board charger for 22-23 trucks

My 24 Flash with 4k bricked with the same issue. SOBDM Module shorted out when I plugged in to charge at home. Also fried a fuse on the HVB. Truck was in the shop for 3+ weeks. Ford covered the repair.

Sobdm A is the on board Charger..

SOBDM B and C are the electric motor controllers(Maybe the wrong term but they are the motor invertor /controler?I dont know but they are related to the electric motors.).

GFM 3 is the second inverter for 9.6 pro power

GFM 2 would be the second on board charger that enables 80 amp charging

Thanks for clarifying. The manual kept calling B and C inverter controllers (ISC) and I wrongly assumed ProPower. But yes the motors I believe are AC and so there would need to be an inverter that converts the DC to drive them.

@Ford Motor Company the OP is experiencing inconsistency of warranty treatment PLEASE HELP !

On it!

Thanks for everyones comments so far. The comments from the dealer are as follows: "Accessed the diagnostic port & performed a scan. U3000:49 control module failure - SOBDM. Performed PPT AJ, AJ1=no. Found the secondary on board control module internal module failure."

The rest of the comments talk about removing the frunk, battery, battery tray and so on as part of the replacement.

I don't see any references to an A, B or C related to the SOBDM to share here. Since I was not able to charge from a 120v or 240v evse, I believe they replaced SOBDM-A (referring to bmwhitetx post) and thus why I thought it should be covered under the 8 yr/ 100k warranty.

I'll message you and grab some details.

Following up here. I've been in contact with @SolarAccountant and working through next steps. Based on the information provided the part should have been covered under the EV warranty.

@Ford Motor Company I got a used F-150 Lightning (from Titus-Will in Tacoma) a couple of weeks ago, and the active support on the forum here was a key reason why I was brave enough to get it! Thanks and tell your bosses I said you're great!

I think I am facing the same scenario. Suddenly can't charge at home on the 120v outlet, nor on the Emporia Level 2 I just installed. But fast charging works, thank goodness. I have an appointment in a few weeks. Any suggestion?

Reset all your DTC's with FORScan or CarScanner, if that doesn't fix it you may have a failed SOBDMA. It's not common, but it has happened to a few people.

That is all Greek to me but I will do some research. Thank you!

If you don't want to mess with anything just take your vehicle by any autoparts store and get a scan/full DTC reset.

Tell them to reset first then scan, don't get a print out of the first scan it will be lengthy.

Can I ask how much would the repair be out of warranty?
