It couldn't be easier to disable auto start/stop on your Jeep Grand Cherokee. This intelligent device simply plugs into the OBD port and restores your preference for auto start-stop automatically which eliminates the need to press the disable ESS button after each ignition cycle.
The Autostop Eliminator simply plugs into the port below the dash in the driver's footwell area on the Jeep Grand Cherokee. While plugged in, the device will work with the ESS system to ensure when you turn auto start/stop off, it stays off.
The device has an LED light that can be turned ON to indicate when it's awake and working. To toggle the LED light ON/OFF, press and hold the auto start/stop button on the Jeep Grand Cherokee until the LED light on the device blinks (~5 seconds). After completing this procedure, be sure to check the state of auto start/stop using the OFF indicator on the auto start/stop switch. Assuming your preference for the ESS system is OFF, you may need to press the auto start/stop button briefly once more.
The Autostop Eliminator can be plugged or unplugged at any time. However, since it does not make any changes to the ESS system of the Jeep Grand Cherokee, the device must stay plugged in for your auto start/stop preference to be automatically restored.
