Autostop Eliminator Causing faults on 2025

[Suli]

Did some testing and I'm getting faults with my 25' ST and the Autostop Eliminator "AE050" model (https://www.autostopeliminator.com/products/2025-ford-explorer-autostop-eliminator). The two faults are:
1. Hill Decent Control (shows in the cluster on startup)
2. Auto Hold (Say fault when I push the button for it in the line of buttons next to the volume)

Removed it, faults went away.

Re-added it, faults came back.

I did NOT plug in a scanner to see what the codes were, but I did just ping the Autostop folks to see if they know. Anyone else run into this issue?

I have a 25' ST with the same AS eliminator. Recent Ford updates have been screwing with the AE eliminator. I am not having the issues you are but at times it hasn't kept the last setting because of updates. The fix is to remove the negative battery cable for about 15 mins or longer anbd then reattach it. That has fixed my issues when the occur.

Ugh, I'll give that a try as well.

Well, that was interesting...

Unplugged the neg term, held the brake pedal for a few min to drain, plugged it back in, started the car, turned it off and let it all cycle off.
Reinstalled the "A-S-S" eliminator, and restarted it. No more errors and now it just tells me on startup that the "Auto Stop Start button was pressed". Interesting, but it's working with no faults again.

So far - I have been using the Explorer (25'-26') Start / Stop Eliminator (since October 2024) on my 2025 Ford Explorer without problems.

I don't believe its the auto S/S eliminator that is problematic itself. Ford over the air updates affect it sometimes and the fix is to reset everything by removing the neg. battery cable. I believe the mandated start / stop is going away with the Trump administration so possibly Ford will make a software change to allow the factory button to hold its last pressed position like the S/S eliminator.

I’m sure you already know this but you can use forscan to just turn off the start stop completely with no need to keep anything plugged in. It also sounds harder to use than it is

My system was updated yesterday - hasn't affected my eliminator.

Not all updates affect it. Only some here and there.

Need a little help, please.

Installed an ASE in our 2026 ST and it works well. But, the "Hill Assist Not Active" message has popped up twice. I disconnected the battery for 30 minutes and that cleared the first message. Yesterday, the message popped up so I disconnected the batter for 60 minutes and it did NOT clear the message.

Other info:
* Battery was charged and the BMS was reset today before disconnecting the negative cable.
* Did not step on the brakes to discharge any residual energy today or when clearing the message the first time.
* Ford Connectivity Package has not been activated yet. While parked in the garage, the vehicle connects to the house wi-fi.
* Ford app on my phone does not indicate that any software updates have been installed since we picked it up (mid-December). The software status always shows "No update available" or "Current software is up to date". And, FWIW, Android 12 is installed.

Questions:
1. Does the ASE need to be unplugged while the battery is disconnected? I did not unplug it when clearing clearing the first alert message and I did not unplug it today.

2. Is it necessary to activate the Ford Connectivity Package for software updates? I don't care much about maps and apps (that are available through our phones anyway) so that is why FPC remains unactivated.

3. Where do I find the software version installed?


Thanks for reading through this long post and for any help to resolve this pesky problem.

I've had zero issues associated with the ASE. YMMV

Combatvet,

Thanks for the feedback. No "hill assist not available" alerts? That's the performance I was expecting, lol, but mine must have a gremlin.

If I can't clear this alert with another battery disconnect (adding a few brake pedal presses), I will unplug the ASE, plug in the stock harness, and see if the alert will clear.

I have had the Auto Stop Eliminator on both 20 ST and 23 F 150 and no problems like described.
