360 Camera Alignment Issues

[adyaro77]

So you ever figure anything out?

I find this extremely interesting. My problems started when I installed tow mirrors on my 24'. The truck was at a couple different dealerships and one that uses forscan. I dealt with it for a while and then the dealership offered to reinstall my standard mirrors and reset the IPMA.

When I left the dealership everything was perfect. About a couple months later the stitching was messed up again. At this point I just decided to put my tow mirrors back on and swap out the cameras. Jesse helped me tremendously and I made some big improvements. I ran the 360 alignment in forscan and it improved enough for it to be tolerable. After a few weeks it's horrible again.

For the hell of it I called the dealership about an hour and a half away from me. They were referred to me when this all started. I called them before and they were puzzled. They were under the impression that they could add tow mirrors to their 24's and quickly discovered that the stitching was an issue. This time they told me I'm not nuts there is definitely some issue. Apparently they have called Ford and they admitted there's an issue. They are now seeing this issue with trucks with standard mirrors and tow Mirrors....and God forbid you get in an accident. They're not able to align them at all. I wish there was a way to reach out to Ford and get some kind of answer. With me unfortunately there is zero support with my tow mirrors on my truck. I'm not taking them off again. At this point I would absolutely love to remove the 360 overhead view. Every other view is perfect.

I think I have the solution. I had some help from @Livnitup and I think I just needed to update the DDM/PDM modules in the truck. I am not 100% sure because I need to recalibrate the cameras using FDRS. I tried to calibrate them with Forscan and I was finally able to complete a second calibration, but the images were still off. I think that is a Forscan problem. (A number of people have reported issues with Forscan's 360 calibration tool.) Unfortunately, I let someone borrow my Mongoose cable, so I was not able to align them with FDRS at that time. I put that truck into storage for the winter before I had a chance to try with FDRS.

Try these Forscan changes and then run the 360 calibration. Please let me know if it works for you.

I am having the same problem with code for calibration, after i added tow mirrors , tried to calibrate but still have code 1578 , i am wondering if you have a camper shell on the back of your truck?

May be worth comparing the asbuilt data on the IPMA of a truck with tow mirrors and one with regular. There are bits for dimensions of the truck in the IPMA. Possible the tow mirror spec truck has different dimension values.

You could try these two settings; if they're enabled, try disabling one at a time to see the result:

7D0-01-01

xxxx

*x--

Rear Camera (RC) • Front Camera (FC) • RVC Split View (RVCSV) • 360 Camera View (CV)

7D0-01-02

*xxx

xxxx

xx--

Aux Camera (AC) • RVC Split View Camera (RVCSVC) • 360 Offset Views (OV) • Steering Angle (SA)

Doing it in the APIM should not concern the IPMA; worth a try? ?‍

I'll give it a go. Thanks!

Yes, you could shut off the display that way, but that would not cure his B1578 DTC. I am not sure why you would want to disable the cameras rather than fix them?!? My brain just does not work that way. ?

I am having the same problem with code for calibration, after i added tow mirrors , tried to calibrate but still have code 1578 , i am wondering if you have a camper shell on the back of your truck?

No, I do not have a camper shell. The B1578 code went away after I made the changes to the DDM/PDM modules and re-ran the 360 calibration. Did you try making those changes as I suggested?

I thought the same thing, but that was not the solution. I compared several IPMA modules with and without tow mirrors. I did not see anything that could be that. I believe the IPMA is getting those values from the DDM and PDM modules.

I am 99% certain I have this problem fixed and that I just need to use FDRS to calibrate the cameras properly. I can confirm with certainty that the issue is a software issue and not a hardware issue. I tested a second IPMA and a second set of mirror cameras. That tells me that the problem is in the module programming.

The cameras on the tow mirrors are located about 3 inches closer to the door than the cameras on the standard mirrors. Three inches of location difference would likely be more than the calibration is able to adjust for. It makes sense to think that the IPMA needs to know the location of the cameras to calibrate and align the images properly. If the camera location is not in the IPMA, it would mean that the IPMA gets that information from another module. The DDM and PDM contain the mirror type in lines 740-03-04 and 741-03-04. It is logical to think that the IPMA is getting that info from the door mirror modules.

When I changed the values in the DDM/PDM, I was able to run the 360 calibration again and the B1578 DTC went away. I was using Forscan, which is known to have issues with the 360 calibration. My image stitching improved, but was not perfect. I believe that I need to use FDRS to erase my learned values and start with the clean slate. I think that trying to make the system adjust the camera values when the initial values are that far off is my problem. Each successive time I ran the 360 calibration it got slightly better. It is quicker to start over than adjust small amounts at a time from a really misaligned starting point.

One other point that might work for @autoxtech is that FDRS has a function to install tow mirrors on a truck that did not come with them. I have seen it while using FDRS. It would not work for me because I am going from tow mirrors to standard. I would be curious to see what modules that function changes. If I had to guess, I would say the DDM/PDM are changed. It also probably activates the power telescoping switch.

I strongly suggest that anyone with this problem starts by checking the values in their DDM/PDM modules. Then clear all of your learned values in the IPMA and run both calibrations using FDRS. I think that is the answer to this problem. I may pull my truck out of storage this weekend to recalibrate it with FDRS, if the snow goes away so I have a clear place to run the calibrations. If not, I’ll do it in the spring and update everyone.
