Are you a Toyota 4Runner enthusiast looking to unlock more insights from your vehicle’s performance data? The factory gauges are helpful, but for true real-time diagnostics and in-depth monitoring, you need something more. Enter the OBDLink MX+ Bluetooth OBD-II Scanner, a powerful tool that seamlessly connects your 4Runner to your Android device, and provides a wealth of information right at your fingertips.
For 4Runner owners who want to go beyond the basics, the OBDLink MX+ scanner is a game-changer. This compact device plugs directly into your 4Runner’s OBD port, usually located beneath the dashboard, and wirelessly transmits crucial vehicle data to your Android smartphone or tablet. Imagine having access to detailed sensor readings, including transmission temperature, TPMS (Tire Pressure Monitoring System) data, ABS, SRS, and much more, all in real-time. This is exactly what the OBDLink MX+ delivers.
This isn’t just about monitoring. The OBDLink MX+ paired with your Android device also becomes a powerful diagnostic tool. Need to diagnose that pesky check engine light? The OBDLink MX+ allows you to read and clear trouble codes directly from your 4Runner’s ECU (Engine Control Unit). Want to measure your 4Runner’s performance metrics like 0-60 mph or quarter-mile times? It does that too. Let’s dive into the features that make the OBDLink MX+ the ideal OBD2 scanner for your 4Runner and Android setup.
Key Features of the OBDLink MX+ for 4Runner Owners
The OBDLink MX+ is packed with features that make it stand out as the top choice for 4Runner owners seeking an Android-compatible OBD2 scanner. Despite its small size, it boasts a robust set of capabilities, supporting all 1996 and newer vehicles sold in the US. What truly sets it apart for 4Runner users is its enhanced OEM data access for Toyota, Lexus, and Scion vehicles, along with other major brands like Ford, GM, Mazda, and Nissan/Infiniti. This means you get deeper insights into your 4Runner’s systems than with generic OBD2 scanners.
One of the most significant advantages of the OBDLink MX+ is its speed. It operates 300% faster than many competing scanners, ensuring smooth, real-time data updates for graphs and gauges within your chosen Android app. Crucially for some 4Runner models, the OBDLink MX+ provides wireless access to proprietary vehicle networks like GM-LAN and Ford MS-CAN, expanding its compatibility and data access even further. If you own multiple vehicles of different brands alongside your 4Runner, this scanner’s versatility is a significant benefit, allowing easy switching between vehicles.
Security and convenience are also paramount. The OBDLink MX+ uses Class 2 Bluetooth 3.0 with 128-bit encryption for secure wireless communication within a range of approximately 33 feet. Pairing is secure, requiring physical access to the device and a button press, rather than broadcasting device names or using simple PINs. Once installed in your 4Runner’s OBD port, you can leave it plugged in without worrying about battery drain. The built-in BatterySaver Technology intelligently puts the scanner to sleep when not in use and automatically wakes up when a Bluetooth connection is initiated, the doors are unlocked, or the engine starts. Finally, for peace of mind, the OBDLink MX+ comes with a 3-year warranty and a 90-day money-back guarantee.
Effortless Installation in Your Toyota 4Runner
Installing the OBDLink MX+ in your 4Runner is incredibly simple and requires no technical expertise. Locate the OBD-II port, which in most 5th generation 4Runners, is positioned under the driver-side dashboard to the right of the emergency brake cable. This port is typically white and easily identifiable.

Simply align the OBDLink MX+ connector with the OBD port’s shape and push it in firmly. It’s designed to fit only one way, and in a 5th Gen 4Runner, the OBDLink MX+ label will typically face upside down. The connection is snug to ensure it remains securely in place even during off-road driving. For added stability during installation, you can use one hand to support the back of the OBD port while pressing the adapter in with the other. Once properly connected, the green power indicator light on the end of the OBDLink MX+ will illuminate, confirming it’s receiving power and ready to connect.

Settings Customization:
The settings section of the OBDLink app is highly customizable, allowing you to tailor the app to your specific 4Runner and preferences. You can configure communication preferences, input vehicle-specific information for more accurate readings, and even define custom PIDs (Parameter IDs) for advanced monitoring. For 4Runner enthusiasts, the ability to access enhanced OEM add-ons directly through the app is a significant advantage, unlocking access to Toyota-specific data parameters. Furthermore, you can control the LED lights on the OBDLink MX+ device, manage firmware updates to ensure optimal performance, and enable data logging features for GPS and OBD2 data for trip analysis and performance tracking. Exploring this section allows you to personalize your OBDLink MX+ experience and maximize its capabilities for your 4Runner.
Customizable Dashboards:
One of the most compelling features for 4Runner owners is the customizable dashboard functionality. The OBDLink app lets you create multiple custom dashboards displaying real-time data from virtually any available on-board diagnostic Parameter ID (PID). The app offers a vast library of PIDs, including generic OBD2 PIDs, SAE standard PIDs, calculated PIDs, and crucially, enhanced OEM PIDs specific to Toyota, Lexus, and Scion vehicles. This enhanced OEM support is where the OBDLink MX+ truly shines for 4Runner owners, providing access to parameters not available with generic scanners.
Imagine creating a dashboard that displays individual tire pressures (TPMS), engine RPM, battery voltage, vehicle speed, transmission oil temperature, engine oil temperature, and coolant temperature – all in real-time. This level of granular detail allows you to monitor your 4Runner’s health and performance with precision.

Setting up TPMS monitoring is particularly beneficial for 4Runner owners, especially those who frequently off-road or adjust tire pressures. Within the dashboard customization, you can add displays and select PIDs from the “Toyota, Lexus, Scion” set, navigating to the Tire Pressure Monitor network and choosing the “IDx Tire Inflation Pressure” PIDs. Through experimentation or online 4Runner forums, you can identify the correct ID for each tire sensor position (e.g., ID1 for front driver, ID4 for front passenger, ID2 for rear driver, ID3 for rear passenger).

Maps and Trip Logging:
If you enable GPS logging within the OBDLink app settings, the Maps section provides location and trip-related information. Upon opening the Maps feature, the app displays a Google Maps view of your 4Runner’s last known location, which can be helpful if you need to remember where you parked, especially in unfamiliar locations. The app also allows you to access and review logs from previous trips, displaying the route on a map, along with trip statistics like distance traveled and time elapsed.

Performance Testing:
For 4Runner owners interested in performance metrics, the OBDLink app includes performance testing features. The 0-60 MPH test measures your 4Runner’s acceleration time, recording the last and fastest times achieved. Similarly, the 1/4 Mile test measures acceleration times and speeds at various intervals (60 feet, 330 feet, 1/8 mile, 1000 feet, and 1/4 mile), along with speed splits (e.g., 0-30 MPH, 0-50 MPH, etc.). It’s crucial to emphasize that these performance tests should only be conducted in safe, controlled environments, and never on public roads, and the driver should not interact with the app while driving.
