Just FYI, Flooded cell and AGM have different charge voltages.
I double checked mine with Forscan and it is set to AGM and 80% charge.
If I had a problem I would change it, but I don't.
This site says AGM's are best kept kept charged to at least 50%.
I have always read any lead acid battery...
At those extreme low temps I would use full synthetic for sure.
And a 0-30 is the way to go.
There is no doubt that a full syn will flow better than a blend at those low temps.
The type of guy you are (tech savvy), I'm surprised you haven't used Forscan the set your charge rate to 90% or so....
Just FYI, Forscan shows my truck to be set to 80% charge and an AGM battery.
I have not had any notifications sense my dealer alarm was disconnected, so I have not changed it
I don't know if the tech can see all that, I kind of doubt it. That is A LOT of data for Ford to store on their servers for how ever many days/weeks/months.
I can tell you they kept my truck overnight for 3 days to find the draw from the alarm.
If you do take it in disconnect your dashcam and amps. They will blame it on them for sure.
Problem is even when disconnected they will still likely blame them.
I guess tell the service writer you disconnected them and it did not help the problem.
I had the same problem and it was a dealer...
So, in a nutshell, service mode simply retracts the pistons all the way and most likely prevents any input like hitting the brake or park brake switch from doing anything?
I've done rear brakes on a Lexus with elect park brakes and the way to do it is remove the actuator and turn the pin to...
interesting. I guess it could be the system trying harder to charge the battery because it's sulfated?
It would be interesting to compare the module's battery settings with my 2023 hybrid's.
