Looking for Mazda i-Stop Eliminator

[Ste Ari o]

So, I’m going to try on another forum after getting blasted on another because the admin didn’t think I’d read my owners manual. Just bought a new 2025 CX-5 Premium Plus. I am not a fan of the I-stop “feature”, and have bought an auto stop eliminator for previous vehicles that were simple plug and play components. All they do is “remember” your last setting, and keeps that setting active. In other words, if you turn the auto stop off, it remembers that setting when you start your vehicle next time. I have searched for this eliminator online and cannot find one for a Mazda. I’m asking if anyone has found one, and where did you get it.
Points to make:

1. I DID ask the service manager if there was a way to turn this off permanently, and was told emphatically no.
2. I HAVE read the service manual, and there is very little on the I-stop feature, and there are certainly no instructions on how to disable, other than for each time you start the vehicle. (I even downloaded a PDF of the manual and did a search).
3. I HAVE been completely through the programming, including all sub menus, etc. and there is nothing about the “feature”.

I appreciate any help, just to make clear; I know that I can turn auto stop off each time I start the vehicle. What I am looking for is this, Autostop Eliminator - Disable The Auto Start Stop Feature. I am just not able to find one for a Mazda.

Thanks again.

These have been available for a long time. See mikstoreph.com (Mazda iStop Disabler Kit) or Aliexpress, where they are probably available more cheaply.

Thank you!

Thank you!

You should first confirm with them though, that these work with your 2025 model!

I looked through the page link and it appears it won't work with 24-25 MY CX-5s with the larger 10" screens. I found this when I scrolled down a little bit::

"

• Not compatible with CX5 24-25 with 10" updated center screen"

Sorry, bummer.

My owners manual has a list of conditions where i-stop will NOT be engaged, If the climate controls need AC, if the battery is low, ... and one of those conditions is if the hood is unlatched when the engine is started.
If a mechanic is working on the car he doesn't need i-stop kicking in and stopping the engine while running diagnostics or adding refrigerant.....

Several videos on YT show how to move the hood latch sensor switch so the ECU thinks the hood was open when the engine was started. I haven't tried it on my new CX-5 yet, but as soon as the warranty period is expired I plan to. Until then I just keep pushing the button to turn it off.

US models dont have hood switch as far as I know

US models do. I haven't bothered to look for it yet. But when I had my car at a shop to get clear vinyl protection over the headlights, I can see via the Connected app that they had the hood of my car up and when they had it closed.

Interesting. May be they added in 2024-25.
My 2018 and 2022 certainly doesnt have.

Bought my 2025 CX-5 not long ago, just curious, what is the speed you need to drive in order for the i-stop to activate? it seem like i did not face any activation on the i-stop yet.
I have purchase the i-stop deactivation dongle online and hopefully it works.

I posted this on another Mazda forum but have not had anyone give it a try. Maybe one of you will try it. Please post your findings. I'm under the impression that the istop eliminator dongles just short out the manual off switch? Just guessing.

This is what I posted.
This happens to bring up something I have been thinking about. It seems that no one has developed and marketed a istop 'defeat' module as is available on other cars. I remember a post where someone took something like a bit of match stick, or something and jambed it in beside the switch button to hold the button in all the time. My 23 CX5 does not have istop so I cannot test this personally. What if:

You start your engine, then
push in and hold the istop defeat button, then
while still holding the istop defeat button in, turn off the engine, and while still holding the button in, you restart and drive a bit.
Does the istop remain defeated, or has it turned itself back on... remember you keep the button pushed in continuously for the duration of this test.

If the istop remains non-functional, then it would be a simple matter of pulling the switch, or going under the dash and jumpering the wires of the istop switch so you have permanently replicated the test.
If anyone wants to try this, please post here for discussion.

I've been looking at '24 CX-5 Premium Plus because it did not have i-stop. I have not been able to find what I want so I'm looking at '25 PP. However I just realized these have i-stop.
I definitely want to find a way to disable it - permanently, or at least so it stays off until I want it on again (if I ever do).

Now, coming from a Ford vehicle and having used Forscan to make customize changes in the vehicle, I see that Forscan is also compatible with Mazdas.
Has anybody here experimented with using Forscan on Mazdas and finding a way to disable it within the computer by switching the setting?
I see that Forscan has a place to enable or disable auto stop/start for Fords. I'm wondering if it is something that Mazda also has.

If you want no iStop and CD in a 2025 model, your only choices are to get a base S or Select trim. Also, turbo equipped CX-5s do not have iStop and CD.

Another way to check with the second gen CX-5s is to look at the 8th digit of the VIN. If it has an L, then it's car without iStop and CD for the naturally aspirated engines.

I’m working on the same issue for my 2025 CX-5. There doesn’t seem to be any dongle or wiring harnesses available for this model. I think the harness essentially has a delay circuit when the ignition power is up it waits a few seconds, and then closes the circuit for a short time to act as if the button got pressed. I’ve actually developed a similar circuit for my heating blanket so that I could automate it. It’s real easy to make, just a couple of transistors and capacitors and an optical isolator. Less than $10 in components, not including special connectors. If I get around to making it, I’ll share the details here. I’d really like to see the wiring harness diagram and pin out for the switch first, but I don’t know where to find that.
