For many of us who own a JL, the Engine Auto Start Stop (ESS) system is an irritant every time you start the Jeep and drive it. You can press the button on the dash to turn it off, but it resets every time you restart the engine. We found a way to defeat the system so that it stays off, and it's extremely easy to do.
There are two hood pin sensors. One is for security and safety features, and the other one appears to only connect to the start stop system, keeping the engine from turning off when the hood is open, presumably for service work. By disconnecting the hood pin wire connector on the driver-side, you disable the auto start stop.
In our testing and on our JL, we have not found that this pin disables anything else. You will have a message flash and then go away in the instrument panel each time you start the vehicle and the ESS symbol stays lit, but we think this is more livable than dealing with the auto start stop system every time we want to enjoy driving our JL.
This is the first in a series of short tech tips for the Jeep Wrangler JL from Dynatrac. We hope you find them helpful, and we'd love to hear your feedback!
