    How to Defeat the Auto Start Stop System

    If you own a Jeep Wrangler JL, you may be annoyed by Engine Auto Start Stop System, also referred to as ESS. Sure, you can press the button on the dash to defeat it every time you start the engine, but we found a way to disable the system so you simply don't have to deal with it. Best of all, it's free and easy to do!

    Under the hood, there are two pin switches that communicate to the vehicle's computer. The one closer to the driver-side appears to only be used for the auto start stop feature. By disconnecting the wire harness from this switch, you defeat the start stop system. On our JL, we found that a warning message appears briefly in the instrument panel when we start the vehicle, and then disappears. The ESS symbol stays on, but that doesn't bother us. We have not found anything else that disconnecting this hood pin affects.

    This is the first in a series of short tech tip videos for the Jeep JL that we are producing. We hope you find them useful!

    I bet you could wire a switch to that wire. A simple toggle to make it an easy off an on when you want it disabled.

    That must be a switch to disable auto stop while the hood is open. Wonder if it would affect remote start if equipped.

    I Think it only affects it if you actually remove the other one. I hate the Ess feature.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
