Another one bites the dust.

The ACM not coming off the list is old news and the PSCM not coming off is new news, but we know about it.

Yea, for sure don't hold your breathe. If you've driven the truck in the snow before and never saw that message, then it's most likely the same shit.

I plan to test my LC function sometime today if the snow holds off, but it occurred to me that there might be something to the order in which the IPMA and PSCM updates are applied. A lot of people seem to be reporting that they do the IPMA, that update rolls into the PSCM and then the PSCM fails to clear the queue. When I updated my IPMA a couple of months ago, I reversed the order. I applied the PSCM first and that update then rolled into the IPMA. I didn’t see any irregularities in the install of either module‘s software and the PSCM cleared the queue normally. Is there something screwy in the handoff between the IPMA and the PSCM if the IPMA goes first?

Just a hopeful thought. I expect to find my LC broken.

Yesterday when helping another forum member, I started with the PSCM, which failed (ReadVinException: Error reading VIN), but still kicked off the IPMA and then the CCM. Went back and retried the PSCM and it was succeful (but did not clear list). BC1.4 working correclty after all udpates. 2021 PB Platinum.

Just more information

That’s encouraging. When you went back to the PSCM, did you do that manually or did the IPMA call it up automatically? If you did it manually, that seems to suggest there actually may be something wrong with the automatic handoff.

@JEB When I installed it in September, I did IPMA first. PSCM came off the list when it got to it and everything went smooth. I installed it the same day it showed up in FDRS along with Livnutup and a few others here.

I wonder if it has something to do with the current version of FDRS? Very unlikely, but the PSCM not coming off the list wasn't happening when the update was first released. Idk what's going on.

@Big Dog Daddy. Lane centering is operational. I can’t tell you whether the IPMA update made any improvements—as I said, I didn’t use it previously—but it didn’t break anything either.

I’m not sure if the PSCM failing to come off the list is necessarily a tell after @Ajzride ’s report, but I’m not sure what’s going on either. I installed the PSCM and IPMA around the end of October—about a month after you did. Maybe it’s worth tracking the order of the updates going forward to see if there are any patterns.

Thank you for testing that out! It's appreciated. I wish, I had done this back in the fall like you and rugedraw did. I'm a little gun shy now on installing it given the mixed results.

Understandable. I would be, too.

Agreed. The PSCM is not coming off the list for anyone recently. That has nothing to do with the issue. Jesse tried different PSCM software on an affected truck and the issue persisted.

New FDRS sucks. It doesnt do a full network scan anymore. So after the updates it doesnt do a submission of the updated DIDs.

The one way to clear it is a PMI. In my new Lightning I had the issue after every update almost.

FDRS removed the network scan button for whatever stupid reason then added it back and it is useless. FDRS does what they seem to call a Lite Scan now rather than an actual scan.

I used to be able to get logs and see the status of every module and the current version of firmware at every location and now it doesnt even ping the modules.

THis is what happens in the new versions of FDRS

THis is how the old versions would report every network scan.

So Fords FDRS team in an effort to fight people like me have made it even worse.. I dont understand their logic this is stupid and pointless. They need to change it back ASAP they are creating more issues than they are solving.

Here is the possible pattern I would be interested in exploring if we could get the data. Suppose you started with the IPMA and everything worked fine say 80% of the time and failed 20% of the time. But if you started with the PSCM it succeeded every time, that could be useful information. Wouldn’t be satisfying in terms of identifying exactly why you get failures in some cases, but the data could flush out a potential workaround for now.

Easy enough to see in vehicle history of the affected trucks, and I have VIN of all of them except the one I found on Facebook who never responded to me. I'll circle back to them tomorrow to see if there is any pattern. Worth a looking into.

This reminds of this:

What trim levels are having trouble? I updated my friends xlt with a 2.7 yesterday. I did pscm first and that started ipma on its own. Total time just about 2 hours for those two updates. No problems at all.
