Method to disable auto stop / start found

[johngreen2609]

I'm sharing my test with the rest of you to use as a exactly that; a test, I can not guarantee anything.
All I can say is I figured it out on my 2017 F150 and it hasn't exploded yet.

2017 - F150 - Lariat 500a

Try at your own risk:

To summarize, I think a 100% auto stop/start disable would look something like this (I left my IPC stop/start message center enabled so I can still monitor it):

BCM 726-48-02 x0xx xxxx xx

FCIM 7A7-01-01 xxxx x0xx xx (optional - disables switch)
IPC 720-01-01 xxxx 1xxx xx (optional - disables stop/start message center on 2017 F150)

Please confirm if you encounter positive results in other Ford: vehicles, trim or model years.

Confirmed it works. I made the change tonight and it seems to work well. Under the current vehicle description it says auto s/s is disabled due to vehicle charging.
Edit: 2018 F150 Lariat with 501A 4x4 5.0 V8

I used this method and it worked perfectly. First time I’ve ever used Forscan. Was very simple. The only challenge was getting the Forscan software to accept the extended use key with Windows.

Thanks for the help.

Can anyone help with a Ford Kuga ST 2018?
Dont have the 726-48-02....

How is it possible to disable start stop?

Thank you

I made & verified all changes in my 2018 Ford Edge, 2.0, Titanium. Dash still shows Auto Stop and allows me to turn on/off. Perhaps the 2018 Edge has different settings?

Another way to disable start/stop AND smartcharge crap system is simply unplugging the thin cable (LIN bus) going to the battery negative pole.
This disabled battery monitoring (and always charges your battery to 100%) and as a bonus kills the start/stop system. Yes tyou will get a faultcode in the BCM but who cares

Used BCM code 726-48-02 x0xx xxxx xx on my 2018 F-150 Ecoboost (Canada). Works great! What a relief. I hate that feature.

I’m not understanding what this start stop is, what are y’all doing?

confirmed.
Works also on a FORD Transit Custom 125KW BJ 11-2017.
Start Stop is off.

It stops the engine when the vehicle stops. there is an electric pump to maintain pressure in your transmission, when you release the break you can drive away immediately. Most people do not like it, and don't want to have to hit a button every time you get in to disable.

I am trying to do it in a Focus 2015.

But when reading BCMii module I can only see from 726-01-01 to 726-01-05.

What am I missing?
