Start Stop Disable

[omar302]

An alternate was was found on the F-150 to disable Auto Start/Stop using ForScan without having to disable the BMS. Can't try it as my Edge doesn't have auto start/stop.

730-01-02 xxxx xxxx x*xx Start/Stop change * to: 0=disabled, 1=enabled

 

This is the Post from the F-150 forums.

That video is not true. You only disable the BMS if that's how you program the car...  If you don't know what you are doing, sure that's when undesirable things happen.  But as someone who understands how vehicle systems and communication works, plugging a random device into my car's network is the last thing I would ever do.  Having some random programmer send broadcast messages startup is how you confuse the car and have "odd" behaviors - properly disabling the stop/start features via FORScan or UCDS is not the 'wrong way'.

Do your research everyone, don't believe what one out-of-touch shop says.

The Auto Stop button is NOT a can bus device. I installed the Auto Stop Eliminator a while back and love it. I had an issue after they tried to reflash my trailer module for the running lights coming/staying on when the vehicle was off. So I contacted them and here is their answer. 

 

Hi Chris,

 

I'm sorry to hear about the issue with the Edge.

 

No, I'm confident our device is not related to these issues. The AE003 is a simple analog device, not a CAN device. 

 

When you press the auto start/stop button on your vehicle, it mechanically touches a signal wire with 12v to a ground wire. The signal wire goes from 12v to ground to tell the vehicle to toggle the auto start/stop. Our device just does the same thing. It takes the signal wire and momentarily connects it to ground to toggle the start/stop. If start/stop isn't toggling, then the device isn't actively doing anything. 

 

It sounds like the tech missed a step that is causing the U2100 code (Initial Configuration Not Complete). Anytime this code is present, the start/stop will be disabled. It's how these vehicles are programmed and has nothing to do with our device. This is why when the device was removed, nothing changed.

There is a small wire attached to the negative battery cable near the post with a clip.  Disconnect that and your problem is solved.

And your battery management system no longer works.

it's great that people have opinions that they share here. what isn't great is denigrating other people's opinions because they're not the same as yours.

in principle, the start/stop feature is honorable; reduce emissions. but where it is actually working against that goal is in my scenario. i've got stop signs every few blocks until i reach a main road. so this "feature" stops and, more crucially, starts a cold engine every few blocks. it's cold here in the winter so i'm not crazy about starting a cold engine a half-dozen times simply because i come to a complete stop at a stop sign for literally half-a-second. i installed the eliminator because of this. if i come to a stop that might be a while then i simply press the button which disables it and the engine shuts down as designed.

my guess is that my engine pollutes a lot less remaining on than getting shut down for a total of 2 or 3 seconds when it's cold.

And neither does the stop start.. as I said, problem solved.
