The On-Board Diagnostics II (OBD2) port in your 2016 Jeep Grand Cherokee is a crucial interface for vehicle diagnostics and performance enhancements. This port, typically located under the dashboard on the driver’s side, allows mechanics and car enthusiasts to access a wealth of information about your vehicle’s health and performance. It’s the gateway for tools and devices designed to read error codes, monitor engine data, and even modify vehicle settings.
For owners looking to personalize their driving experience and unlock hidden features in their 2016 Jeep Grand Cherokee, devices like the Tazer are invaluable. Installation of the Tazer device is remarkably simple, requiring just a connection to the OBD2 port. This plug-and-play design means you can quickly enhance your vehicle’s capabilities without complex wiring or permanent modifications.
The Tazer offers a wide array of features that can be easily enabled or disabled through this OBD2 connection. For models from 2018 onwards, it’s important to note that a Double Bypass or Security Gateway Bypass Module might be necessary due to added security measures. However, for a 2016 Jeep Grand Cherokee, the connection is generally straightforward.
One of the key functionalities unlocked by devices like Tazer is Feature Enablement. Imagine being able to activate SRT Drive modes, including Track, Valet, and ECO. For 2015-18 Scat Pack models, even factory Sport Mode can be enabled, along with SRT EVIC Performance pages and SRT performance pages on the Uconnect 8.4 radio. If you’ve upgraded your steering wheel to a paddle-equipped version, Tazer can enable paddle shifters. Beyond performance modes, you can also enable factory fog lights, a backup camera, and extra video input. Furthermore, features like TPMS disable, DRL adjustments, Shift Light activation on 2015+ (6.4L), navigation lockout disable, and seatbelt reminder chime disable become readily accessible.
For performance enthusiasts, the Line Lock feature is a standout. By simply pressing two steering wheel buttons while stopped, the front brakes engage, allowing for perfect burnouts without rear brake wear. This electronic line lock is a clean and undetectable alternative to traditional plumbed-in systems. When activated, it temporarily disables traction control and, for AWD models, switches to RWD mode.
Adding a bit of showmanship, Light Shows can be activated via the key fob or steering wheel buttons. Nine different light flashing patterns, including customizable options, are perfect for car shows. For safety enhancements, the 3rd Brake Flash feature allows you to customize the rate and number of flashes for the third brake light, increasing visibility during braking.
Driving mode customization is taken a step further with Force Engine Mode, Force Transmission Mode, and Force Power Mode. These features let you lock in specific engine, transmission, or key modes. For example, on 2015+ models, you can keep the active exhaust open with enhanced throttle response without engaging track transmission settings. Hellcat owners can even force red key performance while using the black key.
For convenience, Startup Drive Mode allows you to set your preferred drive mode to activate automatically upon starting the vehicle. If you find the auto stop-start system in Grand Cherokees or Durangos bothersome, Tazer can disable Auto stop-start by default, eliminating the need to manually turn it off each time you start your car.
Steering Wheel Shifting (SWS) offers manual gear control using the cruise control buttons on the steering wheel when in AutoStick mode (excluding 8-speed vehicles). AutoUpshift allows for setting custom shift points in AutoStick mode, ideal for track use. Peak RPM Display shows actual shift RPMs after each shift, useful for fine-tuning shift points. Performance timers like the 0 to 30 and 0 to 60 Timer are also available for performance measurement.
For AWD models, Force AWD modes lets you lock the system in RWD or AWD. Reset Adaptives provides a quick way to reset TCM adaptives, and ESP full on/off gives total control over the ESP, ABS, and AWD systems. Experimental features like Remote Windows and Button Remapping further expand customization. For those wanting to add cameras or video sources, Video Inputs can enable extra video inputs on compatible Uconnect radios.
While the OBD2 port’s standard location is generally convenient, some owners might consider an OBD2 port relocator for various reasons such as security or easier access in customized setups. Regardless of the port’s location, devices like Tazer retain their functionality, offering a seamless way to enhance the performance and features of your 2016 Jeep Grand Cherokee. The ease of installation and wide range of customizable options make it a compelling upgrade for any enthusiast looking to get more out of their vehicle.
