18666 Customer requested 21G01 be performed to enable blue cruise.
Updated modules in order from the instruction sheet. made it to step 19
without issue. Found 21P22 has not been performed so I updated the
OBCC, DCME, DCMF, DCMG, DCMH, RFA, and BCM. The BCM Update Failed twice
without an error code before finally programming and removing itself
from the available updates list on FDRS. Proceeded to step 20, there
was no update from the GWM, moved on to step 21 to update the APIM.
Updated APIM, and now there is an update for GWM. Updated GWM and then
the APIM again before finally being able to finish the program. Test
drove and bluecruise worked correctly. Requesting additional time to
program modules additional times outside of the program so that I would
be able to finish the program in the correct order.

Customer towed in car that would not start. Was able to manually
pop the hood and get the doors open by jump starting the battery,
vehicle would still not start. Connected FDRS and pulled codes. Had
multiple codes that cleared. One stayed P1A10 Which had a TSB out for
it. .Performed PCM software update as per TSB 21-2245. Vehicle now
starts and runs as it should, all codes cleared. FSE instructed us not
to release the vehicle to the customer while we order a part under his
direction.
Replaced BEC (HV junction box) as per FSE. mtime needed for no
coolant bleeding labor op and for road test.

I see they replaced your HVBJB. That's reassuring. When I read your previous update it appeared they only cleared the error codes and updated the software, but the service record showed that they went beyond that.

hhhmmmm, it might be a great thread to add 'HVBJB club' for those that have had HVBJB replaced to gather and post dates and conditions of failure as well as time to repair so that Ford can see everybody in one place rather than sprinkled around in various threads.

I'm still wondering when we'll spot the common thread CAUSING the failures.

Seems to me that the failures are most likely the contactors, but we don't have access to the autopsy data. The most logical CAUSE is opening under load, and the mostly likely time that might not be handled right is when terminating a DCFC session.

pure conjecture, but seems to be fitting the facts.... the failures seem to be higher with people that have used DCFC more often than people who seldom, or never use DCFC. I would love to know if any of the people that have had HVBJB replaced never used DCFC, or sometimes, or many times.

I know of at least one owner who had a fried HVBJB in an almost new MME without ever using DCFC. So I believe it is caused by something else.

They do a DCFC test before they send it out for delivery at the factory, so wouldn’t say never.

I've thought about this too. My two failures both came after a period of heavier DCFC use. The first a few hours after a couple of failed charging attempts at a ChargePoint DCFC (at that ChargePoint I eventually got a DCFC session going after they reset the station). The second failure was 3 DAYS after my 2,000 mile road trip where I had obviously been relying more heavily on DCFC. Even then, the replacement HVBJB failed quickly (while still at the dealership) after zero DCFC sessions.

Both failures were under different circumstances, and the time proximity to DCFC may just be coincidental. The fact that the replacement HVBJB failed suggests that maybe the part is just not very reliable under any type of use.

Me too. When they replaced my HVBJB, the replacement unit failed almost immediately (with no DCFC sessions). Fortunately this happened while my car was still at the dealership's service center.

 

[chaifarm]

I did a DCFC charge on my MME (car had about 1400 miles on odometer) at an EVGo station. Wtihin a week my car had bricked. It has been at a dealership awaiting a new HVBJB, connectors, battery, etc., for nearly 3 weeks. Have no idea if there is any correlation between the DCFC and the subsequent total system failure.

 

[scoopman]

Hey club members!!

I just want to help stir the pot of speculation by saying that I was initiated into the HVBJB club only about 1 week or so after I shot my 0-100% DCFC charging test. That definitely exercised the part that failed nearly a week later. Remember, feel free to post all your stories, but also please report this to NHTSA here: https://www.nhtsa.gov/report-a-safety-problem#index

I drive down to Seattle for the driver electric event and used the ea free electricity at a dcfc charger. When I got home the next night (no further chatting in between) I had charging issues overnight. After work I threw it on the charger and got the pull over safely, thankfully at home.
No such thing as a free charge. HVBJB install started today after two weeks. Hopefully they update everything next week so 2 1/2 weeks minimum.
I felt like it was the dcfc charger that threw it out so interesting to see the comments above.

 

[tfitzgex]

The problem is I have no other way to really charge other than dcfc. I live in a townhouse. No 220v. The fleets of these cars that have been tasked with being police cars or taxis will need to fast charge reliably.

So delaminating switches are warrantyable? Sweet (mine are still good, but it's only been a few months)

do you have assigned parking areas? I wonder if the Association would be open to adding solar carports with L2 chargers as an 'upgrade' , or monthly fee, or Leased equipment ?

The fleets of these cars that have been tasked with being police cars or taxis will need to fast charge reliably.

Most Fleets won't NEED to have DCFC.... I'd be amazed if muni or private companies would spring for DCFC stations as they are VERY expensive.... much more likely to have a row of L2 chargers and give employees incentives to add chargers at homes and parking garages where the vehicles sit when off-duty.

Rental agencies however might be another story where they could have a car come back empty, and the need to clean and re-charge asap to send it back out.

Anything can be a warranty issue if you know the right words to say to the dealer

I have asked the manager, The property owner 'wants to put in level 2 charging' but it would take a lot of electrical work, the buildings are 50 years old..
