Auto stop/start disable?

[FM AZ]

No that the EPA no longer mandates this stupid auto stop/start system, is there new FORScan or Ford software update to turn it off? I see the 2027 F-150 will NOT have it installed!

Not that I’m aware of, but there’s a button to disable it. Seems like an easy enough solution. If they give you the option to turn it off, I’d say it’s not really a mandate, more of a suggestion. When the government threatens your job for refusing their “medical advice”, THAT is a mandate lol

hmm, i used Forscan to disable the auto start stop. The icon still shows up on my dash, but it doesnt do anything. There is a thread here on the forum that shows where exactly with Forscan you go to disable it, you can always go back and turn it back on if you wanted.

Thanks, I’ll check out that thread.

Since I have my ASS disabled from factory, I did a dive into comparing the As-Built files and found a list of relevant PIDs that are changed- to fully disable the system - like a factory delete- however I think there are a few in the PCM that I cannot see a detailed breakdown of the PID - I have a post somewhere on here for it - not long ago a member wanted to enable his and reversed my post to find it did not work - so I am missing some of the files

I didn’t know the factory could do that, I thought it was a mandated item. Cool. I bought mine used so that wasn’t an option. Currently, I just hit the off switch after starting the engine, but I hate it when I forget, and it unexpectedly quits running.

It was Covid related chip shortage- all dealer ordered trucks still had it - special ordered - gave you the option and if you wanted the option- it was a longer delivery time - so the 2022 and I think the 2023 had it as an option

I went with a module you plug into the a.s.s. switch harness. Not the cheapest solution but it seemed cleaner than using a nightlight or playing around with the bms in forscan. Easy to install and works great. -Just another option to consider.

I paid $600 to have mine disabled. Now it chirps 2nd gear and will do 130mph.

It's really not an easy solution for people like me who drive all day and make 10 to 15 stops or more. I'm not trying push a button 20 times a day. I also don't need my vehicle to turn off at every stop sign and red light here in New Orleans or any major city I go to as my business has me carrying expensive items that everyone wants.

Now my wife in her Pilot.... It doesn't bother her because she drives straight to work and back. Not much stopping. I doubt it ever kicks on.

Just plug in a night light or outdated phone charger into the AC outlet. That will keep ASS from functioning.

Yeah, but isn't that still a constant draw on the battery?

I found my post about it -

I think possibly the only one that - I would like to see (if works) over the popular BCM (BMS) disable would be the (PSCM) change - this way BMS stays active

This line is - specific - Auto Start - Stop

PSCM: (Power Steering Control Module)
730-01-02
0001-0101-003D (Disabled) - (013E - Enabled)

One of the inputs required for ASS to enable

• Steering wheel angle is less than 90° from the center position and a steering input change does not occur while the vehicle is stopped

One of the inputs required to force a - engine restart

• Steering wheel is turned rapidly or is at a sharp angle

So, with only this knowledge - it may be an alternative to using the BCM (BMS) disable as you are taking away the (Input) for the ASS system to read (enable)
Now this is (UNTESTED) - so give it a try and if it triggers faults - reenable the setting, but I think it should work the same as the option of the BCM (setting) and taking away the BMS (Input)

Honestly - I think the eliminator - module is by far the simplest option, I call it the George Jetson button pusher - he pushes the button for you at every engine start and you have the simple option - to press the button (if you want to actually enable the ASS system) If I had ASS - I would have this eliminator installed.

A brief understanding of that switch - Its a momentary (Pulse) signal on the Can Bus that flips a logic bit (0 or 1) every time the button is pressed and when the key is turned off - the bit resets to (1) that is its programed latched position - the eliminator module - sends a pulse signal for you (A Simulated) button press

Again below was my dive into the system- in an attempt to find (ALL) settings so others could replicate mine - but I think the PCM is the roadblock and the actual programming of the PCM is blocking the full deactivation of the system - since I do not have ASS or even the switch, its hard to actually test my findings and below was more of a curiosity dive and it stalled in finding any real solutions.

Also, driving in tow or sport mode automatically cuts out the ASS. Itrs also better for the tranny as it eliminates the trans "skipping" gears.
Only reason the trans is programmed to skip gears in drive mode is to save an ounce or so fo fuel by skipping 2nd and 4th gears to automatically let engine rpm's drop=less fuel used.

Hahaha, I know this but I still hit both the ASS button and Tow Haul button every time I start it. Creature of habit. I suppose I could work on retraining my brain to just do Tow Haul. But then I would have to remember that I want to change that habit. It might just be too much.

Not with the ignition off.
