Front Camera Fault & Pre-Collision Assist Not Available Errors

[kennethjk]

I definitely did have 3.6.2 OTA. Maybe that was the HVAC one and I was on 3.6.2 for a couple of weeks.

3.6.1 according to this? Got it Jan. 26

I’m probably going to have the lowest mileage FE after finally getting this error fixed. ?
Car’s been in the shop 32 days so far this year for this cable replacement, which is hopefully the final ‘fix’. I’ve had her in and out since the issue began in August, not in my possession for over 2 total months of that, and nothing from Ford but a $14k eco sport loaner every once in a while. What a crock.

I got this the other day out of the blue. Since then it feels like 1pd just gives up on regen from time to time as I’ve needed to intervene with manual brakes daily since. Engage feels a bit disengaged lol

I believe I was one of the first to post about this issue. I have had my car for almost two years now and this problem started about 6 months in. All told the car has been to the dealer about 8 times and each time they replace a module. Sometimes the fix lasted a coupe months, and sometimes only a day. Once they had my car for over a month and gave me a loaner while Ford sent an engineer. The last repair was in October and the car was OK until a couple weeks ago when the problem cropped up again on a very cold night parked outside. Since then no further issues. I don't think Ford has really figured out the problem yet or at least they haven't figured out a permanent fix. Wish I had better news. I just don't understand why its only a few cars that have been affected. I have friends who have the same car, one is a first edition s older than mine and they have not had this issue

They replaced the CCM in the car. Seems like one of the clips to the beauty cover in the frunk is broken. The report says they had to remove frunk interior.

anyway, the warning and beeping are gone.

they downloaded HVAC software. I ended up with 4.1.1 and after driving home I received 4.1.2

all good so far

So my Mach E is at the dealer for the second time in a month with the Front Camera Fault. Last month they reset IPMA values, IPMA alignment, cleared trouble code, reprogrammed IPMA and related modules. After having the car back for about a week the errors started coming back. After 2 weeks it was permanently on again.

I got the call that my vehicle is ready. I asked what they did this time and the service guy basically repeated exactly what they did last month. So I said, that's what you did last month and it was just a bandaid. He said I know, but since the error message hasn't come back on we can't troubleshoot anymore. I asked why they couldn't troubleshoot when I brought it in with the error message, and he said Ford makes them perform the TSB's first which involves clearing the code. This is a bit frustrating since I don't have any faith in this "fix". I asked what happens if the code comes back on in a week and he said we will have to troubleshoot it again.

Is there anything else I can do to promote an actual fix? Last time it was in I was in contact with the BEV team while it was at the dealer but they didn't help any.

I had the pre collision assist alert, they tried updating software and it bombed out so they replaced the CCM. I have only had the car for a few days but all is good so far,

I purchased a coax cable for the camera located at top of windshield. Part number was LJ8Z-14D202-U and retailed for $40.17

When I popped off the cover to the camera assembly....I noticed the cable was routed in such a way that creates a sharp bend right at the connector.....which happens to be a swivel connection. So, before changing out to a new cable, I decided to swivel the cable so it isn't such a sharp bend.
Might not make any difference but I'll give it a few weeks and see if the faults return.

After 7 tries over three dealerships and 9 months with this problem, I believe my 2021 Mach-E is now finally fixed. Not all dealerships are created equally - they are really just franchises after all, and full of humans with all the various trappings that entails.

As mentioned on this thread and others, I agree that in most cases, this problem seems to be caused by poor design in the way the coax cable is routed to the camera in the wiring harness. Coax cable is not really designed to be subjected to sharp bends. It may have been an issue waiting to happen, or as I suspect, the problem was created or exacerbated during the windshield replacement after the recall for the adhesive. Over multiple visits, typically the car would spend time at the dealership, and then I'd pick it up, in most cases having the problem reoccur sometime on the drive home. Most times, but not all, it would be in reaction to a bump in the road. Some people here have been able to recreate the issue by pressing on the headliner near the camera itself, but not me. It could last for seconds, or up to 10 minutes. At one point it became permanent as there are a finite number of times it can be reported before it sticks. After that module was reset, it went back to being intermittent.

The fault would of course never show up for the dealerships, who seemingly on principle would ignore my suggestion/request to look at the wiring to the camera itself, instead wasting lots of time reprogramming or replacing modules that didn't need it. Much time was spent waiting for components to arrive.

As I had been dealing with the issues for so long, with the car spending almost as much time on dealership lots as my driveway, the car was in for its last time before the buyback procedure would have started. That was when a Ford tech eventually gave the dealership the go-ahead to replace the wiring harness. The wrong part arrived twice, but after installing the 3rd one, I've had no recurrence in almost one month and 1000 miles. I'm hoping this continues, but at least now I'm able to go back to the same dealer and tech to replicate their previous fix if it happens again. Hopefully, Ford will redesign this aspect of the car for the future as it seems to be a weak spot for a number of people reporting this.

Ford customer service is very busy but were helpful to me with rentals etc.

Happy to relate further details of my experience to anyone suffering with this.

The random reproduced are the worst and like crying wolf. Hoping you are fixed. The cause sounds logical and think you may have a fighting chance.

Did it start for most only after the windshield fix? Have not got that one done yet.

@SnBGC is it actual coax cable with one center copper wire in a plastic sheath that is bent around like that? I see the connectors are not the tried and tested screw on crimps we already have along with the tools for crimping and a mile of cable. ?‍

That's so dang obvious that's wrong to me, but I guess windshield techs have no clue. The second picture is the correct routing. If your coax isn't routed properly like the second picture, you may need a new cable.

RF connector technology has moved on from the old-school F-type screw connectors. Most are right angle push style connectors that include retention clips for modern applications.

Never had a problem with any components or crimping the old connections and all of my a/v still uses that one and they work. Modern seems to be $40/ft and not off the shelf. Fast install

Thought I'd share a good news story with you all. After everything else failed, I took my car in on January 3rd for the coaxial cable replacement. The part was pre-ordered, and the only had it for a couple days. And I'm happy to say I've had no problems since with the BlueCruise or camera faults. 2021 California Edition.

My issue started before windshield reseating and continued after reseating. Isn’t triggered by bumps, does it in cold weather, and doesn’t toggle when I touch the headliner. This week was my second visit for this issue to get TSB-23-2040 - was hoping software would fix, but there was conflicting guidance regarding the install, so they reached out to Ford for help and I have to go back. I’m on 4.1.3 via OTA (Job 1 Select w/ Tech)
