Auto Start/Stop Technique

[Mark S.]

Auto Start/Stop is an unnecessary, annoying nanny state "feature" forced upon us and nothing will convince me otherwise!

So there!

Agree with all you have stated , but ford has failed when it comes to battery choice .needs to be agm

With all the electrical components and a large voltage draw, maybe Ford undersized the battery and it needs to be bigger.

Obviously, space is a factor and I'm sure nothing will change.

It's not that I dislike the feature, but that I don't have the choice (without it costing me) to disable it all together.

Several years ago, we owned a BMW that had the auto start/stop feature. BMW offered us the option (for free) to disable it, and if we wanted to use it, the dash button would enable it; reversing how the BS works now...you press the dash button to disable it.

I believe my brother's 2018 Equinox doesn't have a switch to turn off the auto S/S. He's stuck with it always on.

At least we have a choice.

If your battery starts going south like mine did, it hardly ever worked. Thats one way of not having to deal with it.

So there!

Just push the button and life goes on.

This may be true for individuals, but scale it up fleet-wide and you save a lot of fuel. In addition, you put less harmful emissions in the atmosphere.

Please share your data regarding the claim that start/stop systems are "bad" for the vehicle. Bad in what way? I've seen nothing online suggesting that starters or other mechanical components are failing at higher rates on vehicles using start/stop technology. Yes, it's harder on the battery, but manufacturers design all the mechanical components to handle the increased stress/wear. If you have any data I'd like to see it.

Well Id say 95 per cent of us here dont have a "fleet" lol

What I mean is that we are all individual owners who comprise the Bronco Sport fleet. If every one of us kept our start/stop systems enabled we would see significant fuel/emission savings across the fleet. Contrary to a number of posts here, no one is "forced" to participate. If you choose not to you can simply press the disable button after engine start.

ASS is the worst feature for emissions. When I worked for Ford it was already confirmed 90% of the emissions occurs in the first 2 minutes of engine operation until the cat reaches temperature. ASS puts more wear on battery, starter, stops lubrication and cooling system. Not to mention the hazard of trying a make a left turn in traffic.

I know there’s a a third party wire harness to disable ASS. I was hoping I could use FORScan, but it does not recognize a 2025 yet. I’ve read set PSCM 730-03-01 to 00 hex.

Has anyone else been able to disable ASS on a 2025 with a scan tool?

If you can't do it with a scan tool, here's a plug-n-play version for the 2025 BS: 4D Tech | Ford Upgrades, Replacements & Accessories. I run this company's version on my 2023 Toyota Highlander AWD. I run the Autostop Eliminator for the 2021-2024 Ford Bronco Sport on my 2022 BSBB (they don't show one yet for the 2025 BS). Cheers!

When the engine and catalytic converter are cold. They won't cool off enough during an auto start/stop cycle for this to be a factor.

My Wife, is under the mistaken impression that the Auto Start Stop feature is bad and turns it off every time.

So, the propaganda worked on her

I leave it alone and as soon my foot leaves the brake, the engine starts. Its seamless.

I haven't noticed it shutting the engine off prematurely, like at a stop sign, or parking and that could get annoying, if it did.

Thanks for the vid Mark, that is a lot of fuel difference.

BTW, it didn't used to be that way but fuel injection and electronic ignition changed a lot of things.

My '23 BB definitely does not restart after removing my foot from the brake. Seems to start after touching the accelerator pedal most times.

Do you have auto hold enabled in the main screen?

We don't, so that might be the difference.

Yes I do. Didn't think of that, hmm. Thanks for the tip.

The auto start/stop feature restarts the engine when the brakes release. It doesn't matter who is holding the brakes, you or the Auto Hold feature, the engine will not restart until the brakes release. If Auto Hold is holding your brakes the engine will not restart until you step on the accelerator, which releases Auto Hold, or another condition occurs that causes the Auto Start/Stop system to disengage. As mentioned in my original post, I found that one of those conditions is turning the steering wheel.
