Absolutely with out question, every fail will be logged.

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

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?

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.

Best thing we can all do is lodge complaints to https://www.nhtsa.gov so that GM is forced to defeat the auto stop upong request on vehicles that to not have an override. Don't think for a moment that because they say they can't disable it that it's not possible, it's a computer and can be reprogrammed to do whatever they want i to.

I put in my complaint on my 2019 Equinox...
