Stop Safely Now

[Firn]

Sadly I'm victim to the "Stop Safely Now" issue. Red truck icon with an exclamation point and a red battery icon.

Disconnected the 12v, no change

Tried restarting a few times, no luck.

Jumper cables on the way.

I did 2 1 hour trips today AND charged so the 12v should not be dead. Yes the 12v BMS csp was done.

So what happens if you don’t…stop that is

Do you suspect a defective / to weak 12v battery?

 

[The Weatherman]

Did you get a reduced power level?

 

[The Weatherman]

That may be a good thing. It sounds more like an issue with LVB not the HVB.

That’s good because I think they can get it straightened out a lot quicker.

Watching.

 

[The Weatherman]

Did you get any info on what the problem was?

 

[TMND]

Truck returned, runs fine.

I'm working in the garage while it's charging and there is decidedly air in the cooling system....(sigh)...

Glad to hear you got her back OK.

Can you do like an ICE truck and drive on a side hill to get the air out?

Was annoyed to be power limited at 40% battery. Gauge said 91% availabel power

Terminology check, which is which
A SOC of 40% with 91% power to motors is not unusual.

A SOC of 40% with 91% power to motors is not unusual.

Would this power limitation be due to the battery temperature or due to the 21 day delay for module balancing to get full power after working on or near the battery modules? Cell balancing quicker with full charges to 100%? More charges?

They didn't change a battery pack from how I read the prior post only the junction box / contactors?????

Just got back from a night out with the boys, spirited driving, mostly limited access highways and about 18 miles of 45 MPH country roads, on the way home I noted the available power slightly reduced when the SOC was at 42%, arrived home with this 95% on a SOC of 34%. The afternoon trip started at 100% and fully conditioned on the plug.

Oh, you will be stopping...lol



No, not really. CSP was done. Even checked and I had not accidentally left the OBD adapter in.

Charged last night. Two long drives today. No extra 12v loads. It sat at the house for a bit and I took a short trip, but only the one short trip.

About the worst it had happen to it was running the traction battery down to 25% and hitting the Supercharger for a 30% boost. Oh, and using heated seats all day.

As for the battery itself not really. Truck is a 23 purchased in late 24 with 100 miles on it. That's not nice to a battery and it is cold out. So, maybe, I guess. I guess I can't rule that out

How many miles on the truck when it threw the fault?

So I just had this warning pop up while driving. Only going 30mph, still showed full 100% power available. After parking, I plugged in OBD and it found these codes

FordPass gave me this

So, did it restart?

Yes, I gave it 15min while gathering my stuff and logging hours for the day. Error did not come back on my commute home. I'm sending the screenshots to my service advisor, I've got an appt for Apr 4th to do my 40k service. Hopefully just a random glitch. I've double checked that my 12v jump starter is charged and in the truck just to be safe.
