unplugged

plugged
This is what I do. I only need to plug it back in if I want trailer directtionals and brake lights. When you have a trailer plugged in it eliminates the autostop anyway. winwin ,..For me

 

The only thing more dumb then A.S.S. is BMS, Battery Management System. Designed to not fully charge your battery so you can have endless issues during Winter months. One counter acts the other. A.S.S. is supposed to save gas. BMS requires you drive more then you would have to to keep the battery charged.

 

What does BMS actually do?

Is it better to not have it?

If so, is there an effective way to disable?

 

I like AS/S on those really long left traffic lights in summer. It stays off all winter cause of programming for the low temps. If I am in the city traffic and it keeps shutting off I poke the button to disable it. I give the feature a thumbs up 👍

 

It only allows the battery to be charged to 80%. The idea is to save gas somehow. If you drive the truck everyday it may not be a problem. But if you take short drives or drive only a few days a week the battery never gets charged enough. My 2011 was the first year with BMS. I had dead battery's several times. Back then you could just pull the connector near the battery and then it was disabled. Never had a dead battery after that. But now I have no idea how or if it can be disabled. It's a more advanced system.

 

So where can I unplug this at? I don't tow enough for it to be a good option for my '21 FX4.

Still works through 2020 without any kind of warning message. Not sure if 2021+ give a message or not.
Works on FIL's 2016 Honda Accord that ate two Honda five year batteries in four years as well but it has a message that has to be acknowledged on start up.
Neighbor just told me his daughter has to carry a jump pack in her Honda Odyssey because it goes dead so much and no one could figure it out. Told him about unplugging the sensor but don't know if he passed it on.

 

Not sure where people get the BMS only keeps the battery at 80 and somehow that saves gas.

when I do long drives, come home and plug my CTEK in, it shows a full charge in minutes. No way the CTEK bumps my battery from 80 to 100 in a matter of minutes.

as someone who had auto stop/start disabled via forscan (and essentially disabling BMS), I made the switch back to the eliminator as it keeps the BMS active.

BMS can be found in the owners manual, but short story is that it saves the truck from depleting the battery and it’s saved me at least twice. With most owners reporting 5-6years or more on a stock battery, I’d say it’s worth keeping.

 

Regarding the white terminal block in the pictures above to disable the AS/S, my 2021 doesn't even have that white block next to the brake peddle or anywhere else that I can find.
