If so, how did you go about getting to the switch wiring? I wouldn't mind adding a relay if you don't have to tear the interior apart just to get to the wires.
Have not done yet but this is the unit to use..
Small Miniature time on off cycling delay relay 0.1 sec to 9999 hours. 5V 12V 18V DC 5A. Power On Off delay, Cycling. Industrial control and hobby
Amazon Amazon

I purchased the other that was mentioned above but this one is self contained.
Will install when I' get a chance. If you would like to collaborate, pm me.

That makes me wonder if there's a switch that monitors how deep the brake pedal is pushed? On my older TL I just have a switch that measures on and off. This will turn on the brake lights and turn off cruise control.

I wonder if new cars with start/stop have a second switch that measures how deep it's pushed? If so it could be as simple as tapping that switch closed so it never measures the brake pedal deeply pushed.

The 3G RDX has an electronic Brake booster, that has been updated with software twice since the model was released to provide a better brake pedal feel for the driver. I would presume that an electronic brake booster is far more advanced than a 2nd brake pedal switch and can determine and control different functions.

Hi K8KSW here....I just purchased a new 2020 TLX and am very interested in modifying the auto idle stop in my TLX. I really like your solution! Any possibility of emailing you to ask a few details ans questions.

I used the S-VCM muzzler and it disabled my stop start. Such a blessing and easy to install. Only tip is to ensure the car is ice cold (hasn’t run all night/day) before plugging it in.

Where did you get S-VCM muzzler? I found one from a seller in Canada but it’s only compatible with V6 engine only.

VCM = Variable Cylinder Management. It's a feature of modern Honda/Acura V6 engines to shutdown some of the cylinders during low-power operation. AFAIK no Honda 4-cylinder engine has this feature, so there's no need to "muzzle it".

But I put a muzzler on my wife's MDX late one night. Sadly, she figured it out when her mileage suddenly dropped, and I had to take it off.

May have found a solution for you! This was posted on another TLX forum about a device that will turn the auto idle stop off at every startup. http://idlestopper.square.site
It looks like a promising solution. I may order 2 soon so my wife stops complaining about her RDX idle stop

I just read the detailed RDX installation instructions for the idlestopper. I’d rather leave the auto idle stop on than dissemble the dash like that.

You must not hate the auto idle stop as much as me I’m ok with it being turned off by any means necessary! Plus I’ll just have a shop install it so I don’t have to

Certainly your call. Speaking only for myself, the button provided specifically for this purpose is just fine as a solution. Even if I forget at the start, I remember at the first shut down and a quick push later, it's all good. I almost never forget now.

But, everyone has their own way of doing things...

Agree. I just don't get it. One simple button push, less complicated, and easier than buckling one's seat belt...

Yes, its a simple button push, it became part of the process to drive the car, buckle and push the button. I do it in 99% of time, if I forget to buckle, car beeps to remind me.
However, if I forget to press the button in 1% of cases, the car shuts off at the traffic light, and for couple seconds I have confusion/freaking out thinking there is something wrong with the car because I am not used to it. So yeah, its annoying if you forget. Then you remember, and thats when the curse words come out

80 Bucks? Sheez. I got a relay from China that’s does the same thing for about 4 bucks. Easy to set. Just have to get to that white wire going to the cluster....

After a few weeks with the RDX I’ve gotten use to the auto idle off kicking in, it’s barely noticeable and not much of a distraction. However, when the heavy duty Canadian winter rolls in, I can see this unnecessary strain on the battery being a problem. Has anyone noticed battery issues after a few weeks of sub zero winter?

I doubt it will activate in that low temperature. Also, setting the inside temperature control to LO or HI will keep it from activating. One more thing, the battery is upgraded from a "non auto idle stop" vehicle, so even if it did activate, you shouldn't have an issue with the battery.

Cars are engineered to operate in the climates where they're sold. The Canadian cold was considered in the design requirements, as was the heat of desert climates. This isn't a problem for the starting system.

Your right but batteries have a shorter life with hard winters and on the coldest days of the year some batteries fail.

Sure, and Honda knows this too. That's possibly why the AIS system is deactivated at very low (and high) temps.

Not to bump a dead thread, but fyi my solution has worked flawlessly for going on 4 years now......total investment maybe $25-$30 max if you have none of the parts on hand. Plan to take it out when I sell it just in case I ever need it again, though I'll probably go electric and won't need it.

Don't apologize for bumping, just got to get people to search for answers instead of always asking the same questions...lol

By disconnecting the voltage sensing wire entirely, the vehicle thinks the aux battery is dead and will disable the system. I've heard that most start/stop systems have a similar voltage sensing wire, so it might be worth looking into this method.

My auto idle quit working on my 2020RDX, I guess it’s a blessing, but I wonder. Thank you for the heads up that it could just be a three year old battery that is causing idle shut off not to work anymore. I didn’t love the auto shut off all that much, but when it doesn’t work, it bugs me. I can’t decide whether to take it to a dealer or leave it alone.
