Aug 22 build - High voltage battery warning

[AKgrampy]

April 2022 build. AWD Select. I just went out to the vehicle again, powered up, and the SVS and wrench is no longer present. I hooked it back up to L2 charging. Monitoring now. Any advice?

My guess is you have the error associated with the software update. If it were the HVBJB it would not clear as it did in your case.

Darn! I got a charge fault and service vehicle soon this afternoon! I went for a spin around the block, backed in to the driveway, then got the FordPass message Powertrain Malfunction! Here we go!.....

Hello! Send us a private message with your VIN and the name and location of your local Ford dealer. I’d be happy to see what I can do to assist with this concern. Thanks!

Have you asked any forum members to check your error codes?

Ford rep was able to pull the code for me: P0ADE

HVBJB - hopefully it can be replaced quickly! Make sure they order the new part thru COPIS system so that it is expedited.

so this must be a failure post-redesign?

It sounds like a HVBJB failure assuming that is the actual code thrown, but it doesn't mean it's for the same reason they redesigned it. I know that's where everyone wants to go, but parts still fail and bad parts get produced all the time. So it doesn't mean it's due to contactor welding, which was the reason for the redesign. Could just be a failed HVBJB.

Not saying it isn't still a welding issue, to be clear before someone comes to argue, we just don't know. But there isn't enough evidence to suggest this is anything more than a part failure. Especially as they indicate their car still drives fine.

There is a TSB open for vehicles built before Sept 2022 where Level 2 chargers are triggering a high voltage battery fault, they are working on an OTA for that. It isn't an actual problem, just the car being a bit touchy. So if it's just that then they probably won't even get a HVBJB replacement.

well, but the TSB for P0ADE says to replace the HVBJB, so i don't see why it would be some other problem. i agree it's not necessarily welding, but from the standpoint of the user it just doesn't matter why an HVBJB fails.

There isn't a TSB for that specific code, but the service guide for when that code comes up says says to replace it if it has certain other codes also stored. I am looking at the tech manual, and I don't know what other codes were thrown. If OP sends me their VIN I could see what else is there.

As to the comment of the user, you are correct, fail is fail. But I also have an August built MME, and many thousands of others may have ones built after the supposed fix, my point was that we don't need people running around here claiming they are still failing for the same reason because we don't know. It just doesn't help anyone. I thought that was pretty clear since I was responding to someone that said "so this must be a failure post redesign".

that someone was me??? not sure where this conversation is going.

was not claiming that it's failing for the same reason necessarily, but we've had 2-3 "post-redesign" potential failures here in the forum and i'm not sure it's ever been confirmed. that's why i'm interested here to see what really happened.

believe me, i don't want the new HVBJB to be faulty but with all the other random bugs i've encountered in this car, i just don't believe that ford has a handle on any of this.

Sorry, I was trying to get out the door and didn't look at the names. I don't know either, your original comment sounded like you were indicating it was a failure post redesign, or at least questioning it that way. But then when you responded to my post you said it didn't matter if it was the old failure or not. So I guess I would have to ask you where the conversation is going, you changed the rules mid-conversation, not me.

Anyway, probably just misunderstanding and not that critical. I too want to know if it's an ongoing welded contact issue or not, because as I said I have one of the cars that supposedly has the fixed part. And I wanted to take the MME on its first actual road trip this coming weekend! So hopefully it's just a charger thrown fault or something more innocent.

 

[astrorob]

well hopefully OP will update us. i’m really hoping it’s not the hvbjb. based on my limited experience with non supercharger DCFC i think i’m not ready to road trip in this thing. someday…

 

[Xadion]

but the forum HVJB brigade bros said this would not happen

oh well, it will just be "for some other reason the same part broke but not what they fixed bc ford is always 100% on the up and up"

Here's what Ford replaced on my Aug 22 build with 8000 miles.

Wow, it looks like Ford now has reman HVBJBs (based on the RM after the part number). I am surprised they showed you the warranty parts pricing, but as you can see that is warranty pricing on parts only. Labor is still another 6.2 hours plus programming time if memory serves me correctly.

You think it's a refurbished part? I don't what to say if that's true just going ??
