Actually, I believe it's an issue with the script that updates the IPMA rather than anything a tech did or didn't do. It's more about the update script itself rather than anything else.

If they used a powersupply, and connected up FDRS and ran the IPMA update, and walked away to do something else in the meantime, then they would never know that the Configuration step failed due to DTCs caused by network interruption during the software update. That network interruption and setting DTCs happens with most updates...the issue is that the script fails to clear them before moving into the IPMA Config stage....and when the tech gets back to the screen all he/she sees is that it's all done, press OK to continue....

Thanks for this.

Is there any advise that I can tell the tech when they install the new module?

Also, I'm afraid that they will fry the new module Monday. Do you guys know why the update fails and bricks the module?

I agree that @Ford Motor Company has to do a better job at getting a handle on this problem that's been going on for months now. ?

Thanks.

They obviously should know that on a Lightning with a 36Ah 12V battery that they need to run the shop powersupply/battery tester in the proper mode so that it maintains the 13.6V during programming (using a VCM 3 that would take about an hour).

They don't necessarily have to sit there the whole hour...they should be made aware that if they don't watch the "pot until it boils" to see that the DTCs aren't cleared and the configuration failed during that process, that they should take the extra step after the IPMA and PSCM scripted install has happened and clear all DTCs and then separately run the IPMA Configuration tool in FDRS.

But yes....back to your original suspicion....'bricking' the IPMA would likely have resulted from not using a powersupply, or using one that is not set correctly for the Lightning.

Do you or does anyone know how much the shop get's for "time" on this or other updates?

In other words, if they're paid an hour for an hours direct attention, then they better watch the pot boil, not juggle a brake job and two oil changes, but if that's how they're operating then pay very close attention.

The script enhancement should include an audible alert to draw their attention to the situation.

FDRS has zero audible alerts of any kind. I suppose that's due to the fact that it would be used in a noisy environment where they wouldn't be heard even if there were any.

Understand, so I'm suggesting enhancements and bluetooth earpiece, then they can multitask 5 jobs instead of 3

Ok . So I had the 24B56 Done on 01/07/25 on my 23 Lariat. The Invoice states "Updated IPMA and PSCM. Checks Good." But since then, I get the front Sensor blocked error consistently. Just had the vehicle washed so all Sensors are clear and get the error. Usually right after startup and going forward. Then it will pop up randomly. To be honest I didn't really have an issue prior to the Update. Any suggestions on how to deal with this?
Can the dealer just do a quick "check" to make sure all is good (ex. make sure the update took).?
Thanks

Ask them to specifically run the IPMA Configuration tool in FDRS. That may help. Let us know.

Looks like 1.9 hours from the dealer bulletin. If they screw it up they can get up to 12 hours.

Disincentivized to do a good job?

Well Sparky went in Friday to have the IPMA update ran (along with a few other CSP issues). They had the truck all day Friday and the update continually fails. Dealership called Saturday saying it was still failing and to check back Monday.

I really like my dealership (Cook County Ford) and have a good rapport with their service department. The last thing I want is for them to brick Sparky, especially with the cold weather storms coming in this week. I will rely on the truck if the power goes out.

What should I tell them to try next? I read in this thread to make sure the 12v battery is being actively charged and set correctly for the Lightning and to have them watch for communication errors when updating in FDRS. Also to run the IPMA Configuration tool in FDRS once the update is applied. Anything else? I also don't want to come across as an arrogant ass. I've been in IT for 30 years and know how finicky updates can be, and Ford seems to struggle in this area. Something is definitely amiss if Ford's own bulletins to dealerships include an additional 10 hours for failing IPMA updates or replacement modules due to failures.

They have to get it approved in order to claim that higher labor otherwise they are eating it

Mike,

Have you received any response from Ford relating to the information you have posted about this potential script error? It would be nice to know if they are aware and are looking into it. One would think it would be to Ford's advantage to get to the bottom of the issue since the warranty costs for resolving the failed module(s) are higher.

I haven't heard anything at all about this from anyone.

I don't actually expect to.

Even if I told them I was using a PL6100 and a VCM3 and have taken the FDRS training, (all of which is true) they might not even believe there's a problem unless technicians on their own forum start asking questions about it as well. ?‍

Well, maybe they should try doing the programming when the 12V battery isn't at 29% SOC and use a powersupply. That would help. (Insert Ron White quote here).
