Stop Driving Immediately: high voltage battery and power train warning

[Walle1jm]

I’ve described on my own thread but just for documentation purposes, I am no longer able to L2 charge, I receive a fault. Dealer won’t be able to get it in for several weeks.

Update: Ford has assigned me a point person to communicate with. This is exceptional, the ability to channel all issues through one person, it's impressive.

They described they will be working with my dealer to address issues, expedite repairs, and answer any questions I have in the meantime. Additionally, and also exceptionally, they will be reimbursing all gas purchased with the loaner in the meantime.

I look forward to getting my truck back, beyond missing android auto and the ability to guiltlessly idle, I've already chewed through half a tank in less than 2 days with my routine schedule.

So of interest here.. I've had my truck for over a year now.
I charge at home and I plug in when I get home at 6:00pm the latest. My truck is set to charge beginning at 11:00pm so it sits plugged in for 5 hours every single night before the charging starts. and I've only gotten this error once before. . I have nothing aftermarket hooked up.

Interesting. I seem to get it regularly, yet when I check the LVB voltage it is perfectly fine. I've had the message since new and the dealer has multiple F150Ls with a similar situation. If you've had yours for a year, you probably have a 2022 (lucky you - you probably have heated steering wheel and onboard scales too!). I wonder if something changed in the hardware between 2022 MY and 2023.

I found a post that suggests the LVB Battery Management System (BMS) can get out of whack and cause this error. I found the procedure for resetting the LVB BMS so I'm going to try that and see if it clears it up.

Update: last Thursday dealer informed me that the 2nd battery module needed to be replaced, they've been in touch with Ford and the part(s) have already been shipped and were expected to be received and swapped this week.

Dealer was confident I would.be back in the truck no later than Thursday.

I look forward to confirming the above with y'all soon.

Yep that is the update. Same morning, the error codes arrived. I don’t know if they are related or just a coincidence. I’m on vacation 3 hrs from my dealer. Trying to figure out if this this thing is safe to drive home (at reduced power) or not.

are folks thinking the fault errors are caused by the update (and is there a fix?)

I have a 2022 ER

It is coincidence. If your truck will drive it is safe to do so but if the fault reoccurs it will limit your power significantly. Call the customer relations team, ask for the BEV team, and tell them what is going on. They can help if you end up needing a rental to get home

Received these same notices after an update installed. Truck only available with 25% power now

Also not able to charge at home. Receiving red lights and Charge Fault error

 

[GoodSam]

tracking PM/RP problems - see signature spreadsheet - would be interesting to see build dates and mileage, RSVP?

Same update and errors. I had mine towed to the dealer yesterday, they can’t look at it until next week.

I got the same errors yesterday. It was on my Ford charge station pro charging overnight and I noticed I had a charge fault warning in the morning. Those errors came up afterwards while driving. I only had 20% power available while driving.

When I got home I logged in with FDRS and printed all the errors as well as battery module information before clearing the codes. Once the codes were cleared everything was back to normal.

I’ll reach out to the battery team for guidance but it’s my only vehicle right now and I can’t let it just sit at a dealership for weeks.

How did you clear the codes? I’d like to do the same, I think this is a software bug. Had the same happen.

I cleared mine with FDRS but I’d imagine you could use most any OBD2 scanner.
