Asssistance clearing B1578:78 code in ipma.

[PFXLT]

Hi Y’all

Anyone out there with oasis/ford software access able to help me figure out how to clear this code in my ipma? Maybe the workshop manual proceedure? I’ve tried all the processes through forscan. Is this an fdrs fix or just let it be?
My original ipma backup I think is trash because of the fdrs updates I did a year ago. Not sure on that.
21 xlt without 360 cams. I’ve added front park aid sensors, adaptive cruise, and have made changes for TSR and speed limit displaying on my cluster.
Everything seems to be working fine except the speed limit sign in my cluster is bright when I pass a sign but then dims a few seconds later. That may be normal? Haven’t driven a truck with factory speed limit in cluster to know for sure.
This code came up after doing a “write all” to the ipma while experimenting with ipma changes for that speed limit on the cluster.

hit me with the knowledge oh wise group. Haha

It is a code for 360 camera calibration. If you dont have 360 then its rear cam calibration.

Agreed!

I have completed the rear cam calibration 3 times successfully via forscan and the code remains.

 

[Jesse-Infotainment]

DO you have rear cam or 360?

 

[PFXLT]

rear cam only

 

[Jesse-Infotainment]

You have to run the pro trailer back up calibration. not the rear cam calibration Even if you dont have pro trailer back up assist

thanks Jesse

I’ll give that a shot!

Well, we got a ton of snow yesterday so finding a clear parking lot was difficult. i eventually found parking garage and was able to get a pro trailer calibration successfully completed.
unfortunately, my DTC hasn't cleared.

Any other thoughts? i'm pretty stumped at this point. Think it's an FDRS only function?

No. its been done in forscan.have to go below 5MPH and there will be a screen that should display showing the progress.

Yup, did all that and forscan showed successful. it just didn't clear the code.

Anything you can see on your end with my VIN?

The code is for a missing 360 camera calibration for a truck that doesn’t have 360 cameras. I wonder if you accidentally changed the IPMA configuration to make your truck think you have 360 cameras during the last “write-all” that led to the DTC. What does your IPMA show in FORScan (not Motorcraft) here?

706-02-01 XXXX **XX XXXX

Your Motorcraft as-built shows E0 at the asterisks, which is correct for a truck without 360 cameras.

The motorcraft as built is correct. 706-02-01 shows 722B E0C4 4192 when i pull it up in forscan


it has been like this and been there a while (like maybe 7 or 8 months) but i remember back then finding a truck similarly equipped with the features i was adding (adptive cruise/front park aids) but it had 360 cameras. i remember my thought being i can go in and tell it no 360 cams. i wrote all from that vehicle tested a couple things but ended up writing my backup from before doing that session back in. i had way more codes than that for calibration things but those cleared after running those procedures with forscan. this is the only one to remain.

same thing here. 21 xlt, added power fold mirrors. have that code. have tried 360 camera alignment process several times, completed successfully at least once or twice, and the code still remains.

Maybe that’s what we get for messing with factory stuff. Ha ha.
Jesse hooked me up with an IPA file but I haven’t download it yet because we have too much snow and ice to calibrate my cameras now

I have the same error and for more than a month. Jesse did help me too to set up my IPMA. All codes gone after his programming and only this one stays.

NOte: I havent done the 360 calibration yet! Same weather not allowing.

But I did see there is a TSB for Mach-E owners for the same fault code, which list number of procedures to be performed via FDRS.

Were you able to get it solved OP?
