For any of you following this discussion with regards to collision alert issues, I discovered an NHTSA TSB bulletin SSM48049 which describes the same problem on many different Fomoco products. It says DTC U3000:49 in the CCM indicates an issue which requires reprogramming the CCM with latest software level of the appropriate Ford diagnostic tool. Problem evident on some MKC, Edge, Mustang, F150, MKT, Fusion, and Continentals. Now, I didn't see that code on my readout when I ran my diagnostics, but I might have missed it when I cleared some DTCs also. I emailed the dealer service dept that has had my car 3 times already, and asked if they applied this methodology since the SSM was issued in June 2019 after that had my car. Of course, they have not responded to me yet. So it's a complicated matter that I'm still pursuing. Some of you with the same issue may be able to get a warranty fix on your vehicle based on this bulletin.
I have the same problem but do not have any of the expertise you guys talk about.

I think I have the problem solved, we are going to try it on @osanbat9 car this coming weekend.

If this is successful, you could go to the dealer and have them load the correct as built, it seems to have lost this information. One of us will let you know if we solve the problem

LOL,,,, I think driving the smoky mountain route is the best idea yet, but since I'd have to do it without any kind of cruise control,,,, let's go to plan B..... I don't have a laptop, but my buddy does and I think he will let me use it long enough to try the fix we are talking about. I will order this connector:
Amazon.com: OBDLink EX FORScan OBD Adapter: Automotive
and then dowloand the windows version of forscan and try to familiarize myself with what it can do and how I get to the proper modules to do a reset. I don't know how the PM function works on this forum, but you can teach me that too. Man, I feel like I'm in kindergarten again. I think with everything in place, the whole code clearing and resetting the vehicle parameters to standard cruise only will take less than an hours. I can get things set up and running and then call you at a pre-determined time and you can walk me through the steps if needed. I may be able to figure it out myself once I hook the laptop up and open the forscan screens, but I'm not sure. I'd only bother you if I feel I'm lost in the woods. I've had computer experience years ago before retiring, but no experience with the on vehicle diagnostics. I'm sure you have a busy schedule so what would be the best time to try to make all this happen? I'm thinking maybe, this Sunday afternoon? Not really sure that my friend will be available that day, but I'll try to run it by him. Lotsa coordinating to do, plus Amazon has to deliver the adapter first. So I will go ahead and order the OBD Link EX.

I am now just reading the whole thread. If osanbat9 didn't find a solution. My thoughts may be the wiring. rubbing to grounding out. Is it possible to trace the wires and look for damage. maybe wiggling the wires can cause it to go in and out.

I got my car back from the mechanics. And I had him look at it. He said I would have to take it to a ford dealership and have them recalibrate the cruise control radar module. Probably going to get into FORscan and see if I can do it myself. Just be nice to know if someone figured another way

Yes I鈥檓 pretty sure I know exactly what you need to do, it doesn鈥檛 have to do with the calibration of the cruise control module it has to deal with the programming. Try to do a rewrite of your as built data using forscan with factory AB data. If you need any more assistance let me know, I had the same thing happened after a CCM reflash, once The factory AB data was reprogrammed everything worked fine

Bought my 2015 mkc reserve as a used, low mileage vehicle just out of warranty. No issues with the car for 6 months, but battery died while at a tire service retailer and they jump started it for me, advising that it only needed a charge. The battery tested aok. Being a Sunday, I went to a Ford quicklane service center and had the battery changed figuring they are familiar with Fomoco cars. When they told me it was finished, I left the office area and saw 3 techs under the hood and one behind the steering wheel, apparently in conference about resetting all lost memory functions. After leaving the are, about a week later, I began getting "collision alert not available" warnings. They were intermittent, coming and going for periods of ten minutes to weeks. When the alert displayed, cruise, both adaptive and standard would not work. Dealer service said sensor bracket was bent, straightened and fixed. Not so, ten minutes from dealer, same issue. Took car back a week later, they said can't duplicate condition. Problem continued so took back again. Dealer called said about $3,000 to replace and recalibrate sensor and camera by rear view mirror. Months later, when warning goes off now, adaptive cruise will not engage and cannot engage standard cruise. Unable to find solution to this issue that is cost reasonable, and wonder why standard cruise setting is unable to be engaged. I intend to swap out the location 42F 10a fuse for the adaptive cruise system next, but wonder if anyone else is having issues or just my car? The warning sign is constantly lit nowadays. Can turn it off with steering wheel button, but neither cruise works, nor does the car "self fix" itself like it used to intermittantly.
Had my battery changed at interstate after terrible experiences with ford quick lane. Interstate inserted a memory protection device while changing the battery. No problems. Sounds like they didn鈥檛 protect memory properly.
