Service vehicle soon but no reduced power (non-GT)

[Nemy]

Just got the SVS notification while I was driving on the highway and FP powertrain/reduced power message. But I'm on a Premium ER RWD and no reduced power. On restart the wrench is gone too (for now). From what I've read it doesn't necessarily mean the High Voltage issue? Can anyone run my vin? Was planning to go to the mountain tmmrw and won't risk it if it actually is the dreaded HVBJB issue.

Edit: and no high voltage FP message (knock on wood).

When the SVS light comes on with the code for the HVBJB it does not go out on its own and there is a big power reduction when driving. The fact that it reset on the next key cycle would tell me it's not the HVBJB. If the light doesn't come back on I don't know if I would take the time to have a dealer look at it for something they might not find anything. But if it does come back I would highly recommend Newberg Ford, who just finished my latest HVBJB replacement and has a really good EV tech who is very detailed oriented.

Yes.

If it went away on the next key cycle it's probably not serious.

Thanks guys. I'm close to Newberg and Landmark so that's good to know. Also just drove home and still no wrench or reduced power.

P2C94 - Hybrid/EV Battery Contactor Control Supply Circuit Low - Sets when SOBDM senses the contactor relay control circuit voltage is low while the contactor relay is being commanded open.

This is a very rare one, it means the relay that provides power to the BECM isn't getting power when commanded by the SOBDM. The relay box is in the right fender, any damage there? Rodents? This could be a wiring issue, a bad module, or just a software glitch. Could also be caused by low voltage, you just got an OTA the day before which could have drained the 12V battery some.

The one other time I saw this, there was no further work done or resolution, as far as I could tell it was a one-time fluke. I won't worry about it unless it happens again.

FML. "Very rare" - story of my life lol. No damage but I'll check for rodents in the morning. Thanks for the update!
