Disable the Auto Stop feature

306359 Views 262 Replies 75 Participants Last post by  RIT333
The auto stop feature in my 2018 Equinox is driving me crazy. I live in traffic plagued southern California, where creeping along is a way of life. The Auto Stop feature keeps killing the car while in traffic or in parking lots.

The Auto stop turns the engine off when the car comes to a stop instantly. In the case where the stop is momentary, you have to wait for the engine to re-start before being able to proceed.

In traffic, when creeping along, or start-stop, the engine stop has almost caused me to be rear-ended several times.

It also takes too long to start, causing a lag when trying to pull out into traffic. A very dangerous problem when trying to pull into traffic.

The concept is generally useful if there was a long traffic light, however the implementation is poorly done. There needs to be a programmable delay before the car simply turns off, or better yet a switch to disable it when in traffic.

Is there any way to turn this feature off? Or somehow control it?

It doesn't appear that you do "get it"! You seem to have a problem with those who make their own decisions and aren't willing to sign up for your retoric. Maybe you should share your vast knowledge with us and tell us what you know about the drive system failures associated with this product or are you still blowing smoke as in your other posts. I have nothing to get over and the $139 I spent is really none of your business.
BTW, at my last oil change, I showed the service manager the SS module installation on my diesel and he had no problem with it from a warranty standpoint. In fact he asked for information about it because he's had several customers ask about deleting the feature.

I'm going to play a little devil's advocate here - While the Service Manager may not have any problem with the SSS, if by chance it does cause an issue, and if there is a footprint someplace that implies that you used this device, it would be up the GM to accept and deny any warranty coverage, NOT the service manager that may be on to a new job, and working for Ford when a failure occurs.


Again, I am just providing some food for thought. I don't have a fire suit, so please don't flame me !

Actually I do get it, you are an idiot period.

You are also as gullible as they get. You don't think that the Service manager, documented on your file that you have modified the Control module in the vehicle? Of course he did. So now, not only does he not have to even worry about confirming the foot print, he has your admittance of guilt. Further more as RITT stated, the service manager does not get to dictate warranty coverage, he is just an employee, processing you for an oil change. When the time comes to a warranty claim, it will be different. You seem to think you own the warranty, but guess what, you don't. You own the vehicle not the warranty. GM owns the warranty and you play by their rules. I ain't blowing smoke about anything, this product is no different then any other engine tune, they all say they are not visible by the manufacturer, because if they didn't they would not get as many customers. That draws in the gullible ones like you. I can also say, having worked for a dealership, they can and 100% do refuse warranty work for ANY modification to any of the control modules in the vehicle. In court, it would be your job to prove that it did not cause the issue. If you do not think so, read the TOS of service of your service warranty.

But hey, if you want a mod, to prevent a feature that functions perfectly then go for it. You can also go walk off a short bridge, at the end of the day, I don't really care.

PS since you are so gullible, I have land on the moon, I am looking to sell.

OK, not a car guy, so if this question is dumb I apologize. How can something that stops the engine from stopping and restarting void the warranty? Aren't there GM approved situations where the START/STOP feature can be disabled, (maybe not disabled but disengaged) i.e. A/C on high, towing?

It is not what the modification does, it is the act of modifying the Control Module code. It is a computer just like any other computer, un-authorized software modifications, can have ramifications. As a quick example, lets say that the modification software, disables the STOP request, however does not disable the start request, the computer following its own code, sends a start command to the starter, Since the engine is already running, repeatedly firing the starter again is not a good thing. The starter stops functioning, is it the fault of the modification, or did the starter just go bad? As far as GM is concerned, when they run a diagnostic and see that the computer was repeatedly telling the engine to start when it was already running, and there is a modification, warranty void. Then there are the people that say, Oh well I will flash it back before I take it in. That is all good and well, except that is tracked, and that idea does not work so well when it stops working on the side of the road and the vehicle has to be towed into the shop.

I remember a hack for a cell phone that used to make it so you could make free long distance phone calls. That same hack caused a lot of problems with texting for Samsung phones. People had a **** fit about it, yet all while knowing they modified the phone. Samsung said, not our problem. Low and behold, you could flash the phone back and the Chat would still not work. Samsung still denied any warranty work, as the hack was performed on the phone.

The Software that runs our devices these days, are proprietary, and even though you own the vehicle, you do not own the software rights, nor the warranty. It is no less illegal to modify the GM control module software and expect them to support it then, modifying Apples IOS or MS Windows, or Android software and expecting them to support your modifications.

Willing to take the risk

No need to play "devils advocate" RIT. I'm certainly not hanging my hat on the service managers comments. He's a friend and I just wanted to share the mod. with him.

What I'm having a hard time getting across, to some, is that adding this mod. to MY 'Nox is MY business bought with MY money. If my warranty is at risk, so be it. I'll pay up front and move on. My business, no one elses! My purpose in participating in this thread is to share my experience, nothing else!
When I participate in a forum I assume that all participants take responsibility for the validity of their input and decisions regarding their own vehicles. This holds true for myself and has worked well up to this thread. Unfortunately starting with post 195 I've had to adjust my assumption. Name calling, no back up for unfounded assertions and real estate sales on the moon just don't cut it.

If I ever considered buying property on the moon, I would no longer consider it. I'd be afraid that I'd end up with RedOntarioNox as a neighbor.

I'd be interested to hear the forum administrators take on this member and his posting style.

Our product plugs inline with the hood latch switch. It is simulates opening the hood for a fraction of a second after the engine is started. The Equinox is FACTORY programmed to disable auto stop for an entire drive cycle any time the hood is opened. This is a safety feature programmed in to avoid a surprise engine start for a mechanic working on the car. We simply take advantage of this feature already built into the vehicle to disable auto stop.

The module does not modify the software in the vehicle, like a tune. It is designed to precisely emulate the correct switch behavior so that no codes are thrown. This has been verified on GM diagnostic equipment.



Special message to RedOntarioNox:
Hi again. I realize I am the snake oil salesman posing as an experienced engineer, so none of the above is to be believed. Or if it is true, since GM has been following the development and release of this product 10 weeks ago from my little company, they had someone posing as a typical owner purchase it. They surely have had their top engineers reverse engineer it by now. Now that they know how it works, they have downloaded an update to their millions of vehicles, so they track how often the hood is opened. They must have also updated their diagnostic software at the dealerships to track this and issued bulletins to service personnel to keep an eye out for excessive hood opennings. Perhaps they set a threshold so anyone opening their hood more than 100 times a month is suspect.

Hah, I am the guy selling this "do nothing product" to unwitting souls, so this can't be true.

Please, with your extensive experience working at a dealership enlighten us again!

I was *just* posting about how this device should be “undetectable*, since it is a hardware device and NOT a software mod (which would be easily detectable), but saw *your* post and then deleted mine.

I like how you went so far as to say GM might actually now update their software to detect hood openings! That was funny! And that’s what it would take!

I’m glad you posted what you did. Puts a “stop” to all the nonsense.

The system would track all input signals, including the hood release. That is how system diagnostics works. With as many factors that can disable the stop/start function, EVERYONE of them will be logged in the system.

So you have just admitted that, it is even EASIER for them to track and void warranties over your product. :clap:

Hardware of software, your tool is still manipulating the propriety software of the system and as such will still violate your warranty. I bet you $100 right now, activate your device, start the car, call onstar and say, for some reason my vehicle is not stop/starting, they will diagnose the vehicle and come back and say, that the hood release had been opened.

AS far as reverse engineering, they would not need to waste the time, because the information they require is already available to them. They would not need to issue bulletins, because unless it affects the warranty at that time, they would not care, but the moment you have a problem, you can be **** sure the diagnostic tool can check for that.

Of course it's tracking input signals for *status*. That's how it's telling the driver his hood is open.

But you *know* for a fact that *all signals* are also logged (for diagnostics)?

Absolutely with out question, every fail will be logged.

Thanks for your explaination Steve. This whole discussion is getting to the point that it's almost amusing.

With time stamp?
You own the vehicle not the warranty.
Both parties own the warranty. Its as much your responsibility to abide by the warranty as its GM's responsibility to honor it.

In court, it would be your job to prove that it did not cause the issue.
Here in the Sates its not cut and dry. GM has lost most cases to plug in modules. On the other side of the coin they have been very successful at denying clams for not using Dexos certified oils. And rightfully so.

Now data logging could be a separate thread. Just think of all of the information they have gathered on not only error logs, but driving habits, personal settings and on and on.
Can we agree to stop all this BS, if people want to put the START/STOP device on their car its their business, if the warranty is voided because of the device they will have to deal with it.

The reason I ask is because the device apparently just flickers the “hood open” signal *once* for the drive cycle. So you go run a bunch of errands and it’s flickered 5 times, let’s say. What exactly is the computer recording? Is it recording 5 instances, or does it only record one, repeatedly over-writing it?

I can believe the computer is logging all *failures* (that’s essentially DTCs), but not all *inputs*. If it logged all inputs, it would likely include *history*, and then we wouldn’t hear the familiar dealership refrain, “Theres no CEL so we can’t fix it”. Instead, we would hear, “the dealer uploaded my data and was able to replay (and pinpoint) the problem in just a few minutes”.

So *possibly* you have a single “hood-open” event logged somewhere on the computer that doesn’t set the CEL, and can only be seen by a dealership diagnostic machine (and not by a common OBD-2 reader, apparently).

What’s the dealer going to do with this information - suggest you change the hood latch (or its sensor)?

—————
To the SmartStopStart vendor:

1.) If a split second interruption of the hood latch signal is enough to make the computer disable the STOP/START functionality for an entire drive cycle, the logic must be latching that event. Why then doesn’t the driver get notification that his hood is open?

2.) What if a manufacturer *does* decide to update their software, affecting operation of your device (which they could easily do)? Does your warranty include updates to get it working again?

2.) What if a manufacturer *does* decide to update their software, affecting operation of your device (which they could easily do)? Does your warranty include updates to get it working again?

To answer your questions:

1) The SmartStopStart module takes advantage of a programmed feature in the Equinox to protect a mechanic working on the engine. When the hood is opened at any time during the drive cycle, even very briefly, auto stop is disabled in order to prevent a potential sudden restart startling or possibly even injuring a mechanic working on the car. So yes, the state is latched by the ECM. The display module might every once in a while 'catch' the very brief virtual hood opening, and display 'hood open' for a second when when the car first starts, but 99+% of the time the display computer is not fast enough to catch it.

2) Yes, theoretically the software can be changed by the manufacturer. We offer a 90 day money back guarantee on the module and a 3-year repair or replace warranty. In the event the manufacturer changed the software we would make every effort to update our product so it would still work and offer a replacement under our warranty. I believe, however this scenario is HIGHLY unlikely since this is programmed in the vehicle as a safety feature. We have been producing Stop-Start override devices since 2016 and this has never happened. Though they never would admit it, our product is actually helping sales, because some people refuse to buy vehicle with auto stop that cannot be overridden. I have received much correspondence that proves this point.

As far as recording of auto stop override events goes, yes, during a drive cycle, if the GM diagnostic equipment is connected, information is available as to the reason an auto stop event is suppressed. If our module was connected, the hood open event would be seen. This is why I suggest removing the module when going for dealer service, just to play it as safe as possible regarding the warranty. To my knowledge though, this data is not stored beyond the individual drive cycle. It is FAULTS that are stored semi-permanently. If someone were to disable auto stop by disconnecting the hood switch that would generate a fault code that would be stored and provide a record.

I've got the SmartStopStart device in my Premier 2.0T and love the permanent defeat, but I cannot make the remote start work even after hours of it being parked. The sequence I use is to first use the remote to lock the doors, and then push and hold the remote start button, but every time the horn begins honking in the alarm mode. Perhaps I am using the wrong button pushing method?

The remote start button on the key fob remote needs to be pressed very quickly after the door lock button. Some people find it works easier to press them together, and then continue to hold the remote start button until the vehicle starts.

Also keep in mind if it fails to remote start the first time, if do not keep trying again and again because it will not remote start until another 20 minutes elapse. The rule is if it fails to remote start the first time, for whatever reason, start it inside the car for this drive.
