If this works it is great news and kudos to your dealer for troubleshooting and enacting a possible solution. My lazy ass dealer just feeds me the BS about how this is a sophisticated vehicle and the electronics need protecting, blah, blah, blah, as if I'm a techno moron who lives in a cave. Thanks for posting this. Should help a multitude of folks here.
Where is connector C1457B?
You and me both...just had a new 12V installed last week. Showed an 11.19V reading this morning after being driven all day yesterday. Have you had any other work done (wiring harness, Connector C1457B being looked at, other)?? I'm trying to troubleshoot before my next appointment with the dealership tomorrow..
I've got an appointment to have it looked at this Thursday. I did have to have a DC/DC converter replaced at 780 miles. It was not doing the deep sleep thing until after that was replaced. Right now I am not in deep sleep. I turned my wifi off and disconnected the ford pass. I don't know if this had anything to do with it, but something happened. I also have been driving around with the low button on the transmission engaged. It seems to supercharge the regenerative braking. Again, I don't know if this has anything to do with preventing deep sleep. I can tell you that after my car sits all night the voltage is still dropping to around 11.3v to 11.5v, so something is drawing energy from the battery. I think engaging the low setting is helping to keep the amps up on the battery which could keep the truck from deep sleeping. I am going to ask if there is a way to increase the adjustment of the normal regenerative braking.
Per manual = Take to dealer
On my noco 50gbs instructions if 12v battery is below a certain voltage it will not work and to bypass low voltage of the battery the on button should be held down for (I think 3 seconds) to turn off that (safety?) feature.
C1457B is one of the connectors on the DC-DC converter itself. So in @Mikecando's case where they replaced the 12V cable assembly first they probably disconnected the DC-DC converter to move it as part of that procedure and forgot to plug it back it in.
I use Low frequently usually only the last 3-4 miles from home as it will maximize Regen braking and will charge the HVB. The apparent downside is the ice runs much more and it will apparently when hvb gets to 70% or so engine braking occurs. Try slippery mode with low in cruise (I have ACC on my Lariat) at around 42-45mph. When you slow down for turn or ? Push resume instead of pedal. ACC will use 40-50% power for very short time and drop back to electric faster than you could get foot off pedal. I have 16 miles of 40-45mph and this mode will usually result in 53-63 mpg on it
Ford used to have the connector number actually give you a clue to where it is physically located, I was just wondering if that is still the case.
Like I said, no logic, on Foxbody Mustangs the actual number represented how many inches is was back from the bummer.Looks like it's under the hood near the 12v battery.
The only problem with what you're saying (and doing) is that you're recharging the HVB (High Voltage Battery) and not the 12V battery, which is where you're measuring the voltage. And while it's true the the HVB charges the 12V battery (via the DC-to-DC inverter), braking region, driving in "L" to increase region, and the other changes you're doing do NOT directly impact the charging of the 12V battery. It's still being charged at whatever rate the BMS (battery management system) determines is appropriate.
No issues then just reconnecting later?
