Yes, that is the message I see on my Ford Pass. So that is NOT a deep sleep then; correct? I didn't know there was a difference in the sleep messages ("regular" sleep or deep sleep).
That's normal. The car will still take commands but unless it's plugged in and charging it will normally stop reporting back to Ford the status of the vehicle because it's remained unchanged. There's no reason to drain the battery when nothing has changed.
Boy, now I'm really confused. I have kept my car plugged in thinking the LVB would be charged/maintained but now one person says "no" and the other "yes."
I'm not sure my battery meter goes up to 14 or 15 when plugged in. I'll check it again but it usually is at 12.6 or a little higher (but not 14 or 15 volts) and then it sometimes drops from there
Interesting, I couldn't find anything mentioning this in the service manual. @louibluey could you you point me to some documentation on this?
The LVB is maintained plugged and unplugged. Ford does recommend keeping your car plugged in so you are doing the right thing. But even if you left it unplugged the LVB will be maintained, as long as your software modules are up to date.
That is a problem though. My Bronco, for instance will update anytime I ask it to even if it's been parked overnight or a day or two. I've had my Bronco go into deep sleep after 14 days, but was able to get a current status update any of the days prior.
He has very informative threads on this forum that are worth looking at. Sometimes you can see in FordPass it will tell you it is charging the 12v too. I’ve never seen that message though, others on here have.
I stand corrected, it is indeed in the service manual:
Maybe but the Bronco isn't a BEV. Mine has always acted like the OP described and I think it is normal. The LVB in the MME is much smaller than what used in the Bronco, or any other ICE vehicle, so comparing the two isn't appropriate.
Technically the battery is always maintained. If it drops below 12.3v while not in operation it will maintain it. When the vehicle is charging it does maintain it. When the vehicle is in motion it maintains it. It's not always maintaining it at 14/15v during the entire charge. It's always at the start but once the LVB is full it will stop.
The FP system is largely the same and operates on the same principles. My understanding of the post is that FP was not responsive after an hour for the OP as the vehicle is going to deep sleep, which would point to a LV problem.
