This is a non-comprehensive list of stuff you can do without needing a programmer/scan tool. Shamelessly copied and pasted from other sources, just putting it in one location. If there are more, or updates/corrections, I'm happy to update the original post with them. I made this so I can print it out and stick it in my glovebox because I can never remember it.

General Reset for Wierdness
Unplug the negative battery terminal for about 5 minutes
Reconnect the negative terminal
This reboots all the modules and computers in the Bronco
Use a trickle charger rated for AGM batteries:Connect (+) to the (+) battery terminal
Connect (-) to either chassis ground or the side tab on the (-) battery terminal
DO NOT connect directly to the (-) battery post
The BMS system must see the charger and going directly to the (-) battery post will bypass it.
Let the battery trickle charge over night. Low battery voltage, or just the BMS thinking there is low battery voltage, can cause a lot of odd things to occur and this corrects for that possibility.Sponsored
