Red Brick truck in Alaska

[olefish]

This would be Eric in Alaska, with the still bricked truck. I have made it clear earlier, that Ford CIP 23B70, regarding the BMS applies to my truck. As this truck had NL3T-10C652-AD, which is the BMS unit specified in 23B70.
In October of 23 the dealership, before I took delievery, installed CIP 23B57 and the specification says as Per Recall updated and replaced modules. I have been told, this is why I never received notice of CIP 23B70. To that end, I went to the dealership in Seattle and purchased ML3Z-10C679-B, the replacement BMS, and installed it myself on my return to Alaska. Previous, the warnings were, "update not installed due to low battery voltage".
With the new BMS in place, the truck has been installing updates or attempting to. No low battery notification.
Interesting to me, is, after each install, I can put the truck in gear, and it will drive. However, once back in Park or Neutral, it defaults to the Brick mode, red truck with exclamation point. There is a note at that point, push the neutral button for 30 minutes of neutral maintaining.

Also, in conversation with this Service Manager, at this dealer ship, he said I should let someone know that they, the dealership, believe this truck, should have been part of "Safety Recall Report 23V-688". This was a small number of vehicles assembled in July and August of 2023 and had to do with a failed/failing/incomplete solder joint in the electronic cabin coolant heater. This can cause the cabin heater to fail, which I believe also helps to heat and cool the HVB during charging.

My truck was assembled that third week in August, and the recall notice itself indicates to me, that the VIN isn't a sure method of figuring it out. One is told to go to the dealer for help, which I did, and their response was. "Sure enough".

My problems began with the trucks first experience with its first cold weather in December of 24. The cabin heater quit working. That for a couple of weeks, when it then began working again. The second failure was December of 25, during that cold weather, single digits, when the truck ended up in the red brick mode, and the heater maintained the failure.

As soon as cold weather began, I asked the truck to heat itself on schedule. Was pleasant to climb into when the outside temp was 0 degrees. Until it quit working. Four months ago.

Still waiting for the Relationship Team to figure out a plan. Seems like someone could send me a 302A-03A EDC, which I believe is the cabin heater, and I could have a local ASE mechanic install it. It would be a step. Again, for the first time, I was able to put the shifter into drive, and the truck would move, after these recent updates. I have to think that some sort of an OTA reset would get the thing moving, so we can ferry it out of Alaska.

I would be interested in hearing of any other trucks that may have had the cabin heater with the failed solder joint and would like to understand what issues cascaded from that. Did it effect the operation of the HVB? My understanding is total vehicles effected less than 900. Ford won't supply a letter necessary for us to have the truck transported out of State for a repair. Over 4 months in at this point. Warranty expires in October, so I purchased 3 more years

The most accurate way to determine the build date is on your door jamb sticker, there are two dates, at the top is a mm/yy date then at the bottom is a date yyyymmdd embedded in the string of digits, this was the planned build/blend day, but actual build day can vary by days if there were interruptions in production that week.

Example of my sticker, truck's intended build day was June 9th 2022, ie. 06/22 (June/2022)

My truck actually entered production on 06/17/2022 an the "BUILT" status date showed up on 06/30/2022

So with this information possibly you can confirm your truck might have qualified for the PTC replacement.

Not the cheapest option but a Mongoose cable, power supply and a 48 hr FDRS subscription would get you any other updates that are floating out there.

A bad cabin heater did cause at least one truck to fail:

https://www.f150lightningforum.com/...dule-blow-the-hv-harness-fixed-post-47.33569/

And in that case or another case, it also drained the 12v battery somehow.
The brick mode is most often a 12v battery/12v system problem.

The cabin heater is an electric resistive heater using 400V from the HVB and there seem to have been a number of problems with it besides the recall for a bad solder joint, from a search.

If you search the forum here you may find other reports about it.

After you replaced the BMS I assume you reset it with the procedure:

Start Accessory mode
flash high beams 5 times
step on brake pedal 3 times
red battery icon on dash should flash 3 times

However, the PTC cabin heater could be your culprit since your problems began with no cabin heat.

If the PTC caused an issue with the 12v battery system, which it did in another case posted on this forum, then that could still be happening and causing your "brick" failures when out of drive mode and in neutral or park - that is definitely a strange symptom. But the 12v system is involved in many things in our trucks.

Replacing the PTC seems to be a pricey thing to do, so hopefully Ford can assure you that is the problem before you spend the money.

Build Status for my Red Brick Truck is August/2023, the number at the bottom of the sticker is 1202308227106. I think that puts it within the build timing mentioned in SRR 23-V688, but I haven't received any notification.
But, neither was I notified about the faulty Battery Monitor Sensor, of which this truck definitely had. Only because of this forum, was I aware that it was an issue. I consistently failed updates with the low battery warning. I purchased the replacement part at a Seattle dealership, and since its install and reset, there is no longer that warning, although updates are failing, just not the low battery warning. And I did trade out the onboard 12v battery with a Ford replacement. Again, we are on a island in Alaska, the freight service will not accept any EV's, and the Ferry system will only accept a Lightning onboard if it can be driven. If it can't be driven on board, it has to have a release letter, signed off on by a Ford Technician. Which Ford is refusing to do. So, 4 months of no truck, and not much reaction from Ford.com, and I am unable to get the truck anywhere close to a dealer.

The Brian at Ford replied 5 different times over the 4 months.
1. I'll chat with my engineering team and see what creative Solutions we can come up with.
2. I have the team on it. Hoping we can figure something out for you. I'll pass all of this along.
3. I have been working with the team to figure out possible solutions. Even met with Engineering this morning.
4 I have been keeping a close eye on your case. Flagged with team, and I'll see what they say.
5. The team is currently game planning and said this is good info.

Sort of reads like an AI response I think. I have a case number with the Ford Relationship Team in Houston, and it is beginning to sound similar. Always being escalated.

And no one can tell me, if there is a way/method to circumvent what ever "inhibit" switch is happening, in order to move the truck under its own power, shut it down, and then "restart" it, reliably. Which is needed in order to transport it without the now needed letter.

Seems like if the 12 volt system is the issue that in order to do the updates the 12 volt power supply needs to a minimum of the 75AMP size, based on Fords update protocols.

I can assure you that I am a real person. As previously mentioned, I am not customer service myself but I can often find out what the broader team is doing to support our customers. Your situation is a really tricky one given the remote location and I am really sorry this is taking longer than expected as we keep running into hurdles. The team truly is still actively working on it.
