Permanently disable the Auto Start/Stop feature

I've strongly professed my displease about the Auto Start/Stop to Jeep and they have been giving me cookie cutter answers. "The Auto Start/Stop feature can be disabled by pressing the Auto Start/Stop disable button when the vehicle is running".

I absolutely hate this feature because of the many issues I've had with it while driving. The system seems hap-hazzard and runs like it was programmed last minute.

Has anyone found a way to permanently disable it yet? I know the computer checks the disable switch when it first turns on, so I cannot hardwire it to be closed at all times. I am thinking about adding a timed relay in line with the button contacts that will automatically turn the switch high after a delay when the vehicle starts up.

I am willing to bet that the switch is on the can-bus system so it may be harder than I hope to override.

Re: Permanently disable the Auto Start/Stop feature

It might be possible to disable it in the computer system with Witech or CDA. I will check the programming templates, I recall seeing a "auto stop-start" option in some of the module firmware settings

Re: Permanently disable the Auto Start/Stop feature

Yes, some good news!

After several weeks of work, I have created a prototype OBDII module that memorizes the last STOP-START OFF setting and restores it when you turn on the ignition on your 2016 or 2017 3.6 liter Grand Cherokee.




I expect to start shipping them in October or November.
There is a sign-up sheet on my website so I can gauge the size of the initial production run.

It also memorizes and restores the state of the SPORT button!

Here is the sign-up website: www.smartstopstart.com. There is no cost or obligation to sign up for notification of availability.

There is a video demo there also (sorry the audio is slightly out of sync, I need to redo it).

SIGNING UP NOW!!!!

This is awesome! I looked into how that sensor works, and yes, it is on the CAN bus so any type of hotwiring it would only work for that cycle. Your plug in would be perfect and less intrusive. I also sent a second complaint into Jeep just to add to their "numbers". The answer yet again was that this is a fuel economy feature that "cannot" be changed. I call BS.

Thanks again, and I am looking forward to any updates!

Although I won't need it with the HEMI, I always like to see innovative people solve problems.

Re: Permanently disable the Auto Start/Stop feature

My Stop-Start stopped working and I think that it is because of the Sprint Booster that I installed. That is the only mod I have done to my 2016 Summit.
