Jeep, Dodge and Chrysler
Does this product permanently disable Automatic Engine Stop Start ?
Not exactly. This product adds a memory feature to the existing Automatic Engine Stop Start button on the dashboard (the button labeled "A OFF", so that the last selection you make is remembered each time you restart the vehicle.
If you wish to keep the Automatic Engine Stop Start all of the time, simply press the "A OFF" button once after installation of the module. You can always press it again, from the convenience of the driver seat, any time you want to restore Engine Stop Start..
How hard is installation?
Installation is easy and takes just a few seconds for most models, including most 2018s You can preview the easy installation instructions here.
(ONLY for the 2018 Grand Cherokee Altitude and Laredo and the 2018 Dodge Durango SXT and SXT Plus owners please see this page for installation information).
What happens if the module is unplugged?
The module can be unplugged at any time. The behavior of the Automatic Engine Stop Start will then revert to factory operation. This means that the Automatic Engine Stop Start will revert back to on after each engine start and can be manually overridden only for one drive cycle. There are NO permanent changes to the vehicle.
Will the product work with the Remote Start option?
Yes, it works with Remote Start.
Will the product cause any vehicle faults?
No, it does NOT cause any vehicle faults, warning messages, warning lights, stored fault codes or warning tones.
Does this product affect my warranty?
Per the Magnusson-Moss Warranty Act, a manufacturer can only deny a warranty claim when an aftermarket component is installed if the dealer or manufacturer can prove that the aftermarket component caused the failure. To avoid any possible question ever arising from lack of knowledge of this product by the servicing dealer, we recommend removing the module prior to bringing the vehicle in for any service.
Will this product affect the performance or reliability of my vehicle in any way?
We have carefully designed and extensively tested this product on multiple vehicles and have sold thousands of modules. There is no evidence whatsoever it will cause any problems. This product does NOT cause any vehicle fault codes to be set.

Why did the module change from a diagnostic port plug-in under the dash in earlier years to an under the driver's seat plug-in for many 2018 Grand Cherokees and Durangos, the 2018 Wrangler JL and the 2019 Cherokee?
Recently Jeep and Dodge installed a diagnostic port firewall on many models so aftermarket devices like this can no longer access the diagnostic port. The under the drivers seat (Grand Cherokee and Cherokee), or under the dash (Wrangler JL) plug-in is easy.
I have a 2018 Wrangler JL and want to disable ESS. How do I decide between the Taser JL, Flashcal and SmartStopStart?
If you really need all the extra features of the Taser JL or Flashcal besides ESS disable, then you probably should choose one of those products. If your interest is primarily disabling ESS, then SmartStopStart will save you significant money.
It is also worth noting that SmartStopStart is the only option that easily lets you revert to ESS back on at one push of the original factory ESS override button.
SmartStopStart also does NOT disconnect the Security Gateway (SGW) like the Taser JL and Flashcal do. With the Taser JL and Flashcal you must reinstall the SGW prior to visiting the dealer or their diagnostic equipment will not function. Be aware that a disabled SGW can also leave your vehicle more vulnerable to cyber-attacks, particularly over-the-air attacks.
Why are the the 2018 Grand Cherokee Laredo and Altitude and the 2018 Dodge Durango SXT and SXT Plus harder to install.
The under seat connector used for the other 2018 GC and Durango SmartStopStart modules does not exist in these particular models. We have developed an alternate design that uses the diagnostic port plus a supplementary cable. The supplementary cable requires a bit of interior disassembly to install just on these models.
