The primary purpose of Auto Start-Stop feature is to reduce fleet emissions for the auto manufacturer, not save you gas money. This is why they have devoid us of an option of permanently disabling this function. Fortunately, there is a workaround to this, and does not cost any money, its just a matter of unplugging a wire.

  1. Locate the main 12V battery.
  2. Remove the Intelligent Battery Sensor (IBS) plug connected to the negative terminal of the battery.
  3. The system is no longer able to detect the battery condition and goes into bypass mode, permanently disabling the Auto Start-Stop.

After removing the sensor, you will see an alert “Start/Stop Unavailable, Service Start/Stop” in your instrument cluster screen every time you start your vehicle – but it goes away by itself after a few seconds.

The IBS sensor is located on the main 12V battery under the hood. Remove the plug from the sensor on the negative pole.

The method is a little different in Wrangler, pull up the button type sensor that detects closing of the hood and unplug the wire beneath it. Don’t worry, it won’t show you hood open warning in dash, as the button sensor on the left is for that purpose. The one on the right is only linked to Auto Start-Stop.

What is Intelligent battery sensor (IBS) for?

The IBS continuously analyzes the status of conventional 12-volt lead-acid batteries and provides information on parameters such as state of charge (SOC), starting ability (SOF) and aging (SOH) of the battery. The sensor is essential for the reliable operation of vehicle start-stop systems. It can be used on any standard battery. In addition to monitoring the battery, the IBS also helps in the detection of defective electronic vehicle components, since it also monitors the quiescent current. The sensor improves the diagnostic capability of the car and enables warnings of possible breakdowns, even if they are not caused by the battery. With an improved charging strategy, the IBS also extends the battery life by 10 to 20 percent.
