The Complete DIY Guide to Updating Your Mach-E with FDRS

[Mike G]

There is a fall-back if the USB doesn't work it will go through OBD, which will take hours and would require the power supply.

I just did one where it said something about doing that and I said to re-try and it went through as a USB update the second time. Just a hiccup I suspect.

I also had the USB error when I was doing the big update weekend, the few times I encountered it I never used the OBD backup. Just re-tried and it was successful. FDRS seems to act up sometimes.

Good light reading for those who do their own updates.

Mike G, this is actually really useful info for some things I had been doing. Much appreciated!

Based on information in another thread, the OBCC update that showed up for me on Feb 22 is
24-PU0119-DC-CHG4. So I am all set for when I get the adapter.

I have a 2024 Ford Maverick Lariat now and nobody on the Maverick Forum is even talking about programming.....so boring! I miss my Mach-E just for the programming aspect!

New RFA update today, are these PSU required updates? or just a quick one like TCU?

RFA updates generally aren’t quick. This one took around 30 min and my windshield wipers were going the entire time.

I meant to say, lift up the arms on the wipers so they don't keep wiping a dry windshield for 30 minutes.

Good to know. I was updating a Lightning not too long ago and I noticed the wipers going off during one of the updates. Confused the heck out of me.

Exactly. What do the wipers have to do with an RFA update? I have no idea.
