Methods to Disable Auto Start Stop Wrangler
Fortunately, Jeep Wrangler owners have several options to address the ESS system. These methods vary in complexity and permanence.
The Simple Button Press: A Temporary Fix
Every Jeep Wrangler equipped with ESS has a physical button, usually located on the dashboard near the gear shifter or climate controls, that allows you to manually disable the system for that particular driving cycle.
- How it works: When you press this button, the ESS system will be deactivated. A notification light on the dashboard will typically illuminate to confirm that ESS is off.
- The limitation: The critical drawback is that this setting does not stick. Each time you turn off the ignition and restart the Wrangler, the ESS system will revert to its default “on” setting, requiring you to press the button again. This makes it a convenient temporary solution but not a permanent ESS solution Wrangler.
Aftermarket Modules: The Plug-and-Play Solution
For those seeking a more permanent way to remove auto start stop, aftermarket modules offer a popular and relatively simple solution. These devices are designed to interface with your Jeep’s electrical system and automatically disable the ESS system every time you start the vehicle.
- How they function: These modules typically plug into specific ports within your Jeep’s OBD-II (On-Board Diagnostics) system or directly into wiring harnesses related to the ESS. Once installed, they essentially “trick” the vehicle’s computer into thinking the ESS system has been manually disabled by the button press, and they maintain that setting across ignition cycles.
- Ease of installation: Most plug-and-play modules are designed for straightforward installation, often requiring no tools or special knowledge. They are usually inserted into the OBD-II port under the dashboard.
- Reversibility: A significant advantage of these modules is their reversibility. If you decide you want to re-enable the ESS system, you can simply unplug the module. This makes them a good option for leased vehicles or owners who may want to revert to stock settings later.
- Reliability: Reputable aftermarket modules are generally reliable and are engineered to work seamlessly with your Jeep’s existing systems.
- Cost: Prices can vary, but expect to invest anywhere from $50 to $150 for a quality module.
Popular Types of Aftermarket Modules:
- OBD-II Dongles: These small devices plug directly into your OBD-II port. They are the most common and easiest to use.
- Under-Dash Harness Connectors: Some modules require you to disconnect and reconnect specific wiring harnesses under the dashboard. These can be slightly more involved but offer a direct integration.
When choosing an aftermarket module, it’s crucial to research brands and read reviews to ensure you’re purchasing a product designed specifically for your Jeep Wrangler model year and that it comes with a warranty. This ensures you’re not just getting a Jeep Wrangler ESS delete but a reliable one.
Programming and Tuning Devices: Advanced Control
For Jeep Wrangler owners who want more comprehensive control over their vehicle’s performance and features, including the ESS system, programming and tuning devices offer a more advanced approach.
- What they do: These devices, often referred to as tuners or programmers, connect to your Jeep’s computer and allow you to modify various engine parameters, transmission settings, and feature behaviors. Many of these devices offer an option to permanently disable the Auto Start Stop system.
- The process: Typically, you’ll plug the tuner into the OBD-II port. The device will then read your Jeep’s existing software, and you’ll use its interface to select the option to disable ESS. The tuner then writes the new software to the vehicle’s computer.
- Additional benefits: Beyond just disabling ESS, these tuners can often offer other desirable modifications, such as adjusting throttle response, increasing horsepower, altering gear shift points, and disabling other features you may not want. This can be particularly appealing for those looking to optimize their Jeep’s performance for specific uses, such as off-roading or towing.
- Considerations:
- Cost: Tuning devices are generally more expensive than simple plug-and-play modules, often ranging from $300 to $700 or more, depending on the brand and features.
- Complexity: While many tuners are user-friendly, they do require a bit more technical understanding than a simple plug-and-play device. It’s essential to follow the manufacturer’s instructions carefully.
- Warranty: Modifying your vehicle’s software can potentially void your manufacturer’s warranty. It’s advisable to check your warranty terms before using a tuning device. Some tuners offer features that allow you to revert to the stock tune, which can help mitigate warranty concerns.
- Legality: Ensure that any modifications you make comply with local emissions regulations.
Reprogramming the start stop system in your Jeep Wrangler using a tuning device gives you the most flexibility, but it comes with a higher cost and a greater responsibility to understand the implications of software modifications.
The “DIY” Wire Tap Method: For the Technically Inclined
For those comfortable with basic automotive wiring, a “DIY” approach involving tapping into specific wires can also achieve a permanent ESS delete. This method is more involved and carries a higher risk if not performed correctly.
- How it’s done: This typically involves locating a specific wire or set of wires associated with the ESS system. By strategically interrupting or bypassing a signal in this circuit, you can prevent the ESS from engaging.
- The risks:
- Electrical Damage: Incorrectly tapping into wires can damage your Jeep’s electrical system, leading to costly repairs.
- System Malfunctions: Disrupting the wrong wire can cause other vehicle systems to malfunction.
- Warranty Concerns: This method is highly likely to void your vehicle’s warranty.
