Mine is still at the dealer, going on three weeks now. I’m disappointed in my service manager as he estimated it would have been ready last Monday and blew past that date without an update. I called on Thursday and left a message still no update.
I'm having a similar problem with my truck. It blinks off and on going to a gray screen when it does this and back to normal. The 'guideline aids' also blink off and on during this process. Been doing this for sometime now and I finally had enough and made an appointment to get it fixed. Reading this thread, I can see that issues with getting a timely repair are not easy. I hope that it turns out well in the end. It also gives me some info on what kind of conversation I'll have with the service writer. I've already been told that they have no loaner to let me use on the initial troubleshooting visit coming up. Some really lame excuse on the loaner issue. That's strike one as far as I'm concerned.
When I went in to make the appointment, I showed the service writer what it was doing and he immediately chose the APIM as the problem. I don't blame him for not having a clue about it. After all, he's a service writer, not a mechanic. I have some reasonable knowledge of this type of thing. I was a mechanic, in the business for 35 years until I retired. I also have the repair manual for my truck. All 15.5k pages of it. So, I've been doing some research into this. I've also been using forscan to check for fault codes and there are plenty of them for my issue. The main one seemingly, on alignment and adjustment. I have the max tow package and the trailer assist so, my truck has a few more modules than the average. My guess, for the moment, would be the IPM "B". That's the image processor. Since I only have the rear back up camera, I don't have the 'A' module that's used with the 360 view as well. The IPMB is used to provide trailer specific target data found during setup that must be stored in the IPC. That was pretty much a direct quote from the manual. For the moment, I discount the camera as being the problem as it works to show what's happening. It could simply be a bad connection somewhere in the system. Anyway, well see what happens after their diagnosis and hopefully, a good, credible, explanation.
That's what I expect my dealer to do after their diagnostic procedure. Did they also recalibrate the alignment and adjustments? I'd like to know about what I might expect they will do and the explanation as to why they came to replace the IPMB.
Generally when you get lines like that, it's a sign of a bad graphics processor. I doubt changing out the camera, recalibrating or updating software will fix it. The issue will appear to be resolved at times, but mostly only when the truck is cold and the sync module hasn't warmed up yet. Electronics, especially chipsets are very heat sensitive, which normally it isn't a problem unless you've got a compromised processor.
this post was pretty much right. They said that module has something to do with the graphics processor. As far as alignment and stuff they didn’t say anything and it wasn’t on the paper work

OK, that leads me to believe that my problem may be solved with a simple realignment and/or adjustment since one of the codes I get suggest this fault. But, I also get other set codes in reference to the IPMB but are not specific. I do not have the same situation with my screen as you with the lines and I can see why they would replace the IPMB to correct. Hopefully that did the job. Mine, on the other hand, just blinks gray and comes back with just the picture or the picture and the guidelines. It's almost on a timer like every 5 seconds. Since I have the max tow option, the camera needs to be aligned to properly set up a trailer. If you don't have that option, it may have not been necessary to do this alignment.
Well, here we go. Just got back from picking up my truck from the dealer for the camera issue. They tell me the camera needs replacing....Ok. They'll have the replacement in tomorrow at which time I'll go back down with my truck when they call. They'll have it for a couple of hours for the replacement and they will NOT be doing an alignment. Hopefully this is not the beginning of 'throwing parts' at it. We'll see.
This is an update on my issue. Rather then type a string of post, I'll use this one for updates.
My dealer called this morning to let me know they have the new camera they say will fix the issue. I'll be bringing the truck in tomorrow. I also want to say that I had a conversation with the service writer on the procedure for aligning the camera which is needed for the 'Pro Trailer Backup Assist' (PTBA) to work properly. I held back the fact that the IPMB threw the DTC, B1530, which is the code for a camera alignment issue in regards to the PTBA which has been present all along. However, I did ask him about a camera alignment for the PTBA and his answer was anything but positive. He did everything but admit that they will not do this service because it's too complicated and made it seem like it was my problem. In fact, most questions I asked made it seem like it was my problem and I was an annoyance for taking up his time on the issue as he tried to end the conversation as if I was also wasting his time.
Anyway, when I bring the truck in, I'll have no further discussion on it and let them just replace the camera. When this happens, the technician should go in and at least, erase the code set as a final part in the procedure. Even if he does, I don't believe it will solve the alignment issue and the code will come back. Just my opinion at this point. I'm almost positive replacing the camera will not resolve the issue because I don't believe they have/will follow the proper procedures laid out in the repair manual. I'll know it almost immediately when I get home.
Ok, brought the truck back into the dealer to have the backup camera replaced. As I expected, they called me up just now to tell me they need to do another procedure that was originally discounted previously by them after I said they'd need to do it. So, as I write this, they are doing the camera alignment procedure the service writer hemmed and hawed about previously. At least they are now attempting to do the job right. I'll check it out when I get home after picking it up.
