the EFB's will work fine, just won't last as long. that would be your normal 3 to 5 years as oposed to the 8 years + of a agm.
Kinda correct; the BMS will reset itself after 8 hours if certain conditions are met. Vehicle has to be left in total sleep mode and untouched. You cannot pull it up in Fordpass; you cannot unlock it or even get the keys within 25 feet of the vehicle, and you cannot have anything plugged into the vehicle that will draw any juice from the 12v battery. Even then, the purpose of this is to reset the BMS data quality if the data is corrupted. The proper thing to do is to reset the BMS when a new battery is installed. The only way (that I know of) to know if the BMS data quality is corrupted is if an OTA fails to install and you run the VIN if the vehicle in PTS and look at the OTA dashboard to see why it is failing. It will clearly tell you the BMS data quality is off. See screenshot below from the OTA dashboard of a vehicle with a failing OTA update:
FORScan is the only way a DIY user can reconfigure the BCM to reflect the battery type being used.
@rugedraw Can you provide any documentation on the effect that BCM Parameter has for these two cases:
Tbh, I don't know. As I mentioned above, I am not sure what effect (if any) the BMS system will have if the BCM is configured for one type of battery and another type is used. Based on my non-expert knowledge of the differences between a flooded battery and an AGM one, I don't see why it would matter. All I am saying is that if it were my vehicle, I would want the BCM to be configured for the type of battery that is in it regardless of what Ford says.
I also do not use the 8 hours method, I have only used the BMS reset method (we both listed the same steps earlier) but in the link you provided, that BMS reset method is listed as the "last resort" method .. yet that method is the one Ford documented in the Ownerās Manual.
the important thing is not only to reset it to the right type of battery, and there isn't much difference between a agm and an enhanced, but there is. but more importantly you are reseting it to tell it that there is a new battery in the vehicle. with the new smart altanators and such the charge profile changes over the life of the battery to keep it working as long as possible. if you don't let it know you have a new battery through the reset then the charge profile will be wonky and you can actualy dammage the battery. while it might not be apartent right away it will show up in ways like a 8 year AGM only lasting 3 or 4 years, or a normal battery only lasting 2 years.
This. We've never gotten more than three years out of a battery in the Valley, and only that long because it died while we weren't keeping up with timely replacement.
Note that thread is specific to overcome over the air updates not installing due to the 12v battery not meeting the parameters of the algorithm set by Ford to have them safely install. So it is last resort in the particular case of not getting an update to install. I referenced it because overall, the info there is good to gain an understanding of how the BMS system functions in general.
I don't mind the blue hues in mine,but I didn't care at all for the interiors with the orange hues!! Most of the blue in Mine in front and behind the shifter are covered with stuff like glasses and bank withdrawl slips [drive thru banking] in front of the shifter and calculator and tissues behind the shifter!!
Picture of the BS BB I had!!
