New Power-Up OTA Update 4.2.4

[mflynndelta]

What are you looking for in brake regent? (4.2.4 is a TCU update)b
I monitor brake regen pretty closely and I haven't seen anything change over the last few updates. (I'm at 4.2.2)

I would think it would require at least a PCM update. And perhaps BCM & ABS?

I just received 4.2.2 whole driving a few
Iminutes ago. Nothing changed that I can see.....

Before an update can fail due to low battery voltage, it has to be sent to your truck first. Having a low SOC will not prevent an OTA trigger from being created for your truck, but it can prevent the update from successfully installing.

Edit: It is also good to reset the truck's BMS every now and then. You can have a good battery, but if the BMS is not reading it correctly, it will make your truck think the battery has low voltage when it is not the case. I just helped a member of F150 forum out less than an hour ago that had a TRM update failing over and over again due to low battery voltage. I told him to reset the BMS, he did, and the next time he initiated the update, it went through without a glitch.

How do you reset the BMS just curious ?

Either with FORscan, or there is a sequence you can do from inside the car. Key on engine off, flash high beams 5 times, then pump brakes 4 times and the battery symbol on the dash flickers indicating it was done. Something like that. I know there's a YouTube video that shows it, but I'm driving now. Can't look for it.

Received this update last night, then checked in PTS. It was a TCU update only, which aligns with 4.2.4 in the wiki.

I got mine yesterday too.

Accessory mode, flash high beams five times, tap brake three times watch battery icon on the dash for three flashes and then starter button back off.

If you've just downloaded 4.2.2 and you don't see a change, you'll have to either reboot the Sync system or shut the truck off and get a burger and fries and when you get back it should be updated to Sync 640...like magic.

4.2.4 installed this afternoon on my truck. After restarting a couple of times. The wireless hands free calling static during calls I reported last night is gone. I guess I just had to wait for the entire 4 xx package to complete.

The next time a 2021'r claims they are the forgotten stepchild of the OTA family, I'm going to point out that they are currently passing right by a chunk of their 2022 brethren. ?

NOPE

And I've still got Securialert. Do we have definitive confirmation that 4.2.4 disables it?

Yes, unless your like me and the truck says it installed but PTS says it failed.
