F150 Forscan Side Effects? Disabling Auto Stop_Start

Post by tperk100 » Mon Feb 11, 2019 10:27 pm

On F150 to disable Auto Start_Stop we disable BMS (Battery Management System). What is BMS and what are we doing when we disable it?

Here's a pretty good write up on BMS.

Long story short, it's a system that monitors and protects the life of your battery. Disabling it returns you to a similar system as older vehicles. The battery may have a shorter life because it is allowed to overcharge or undercharge based on load.
