That pesky check engine light on your Subaru dashboard – it’s a signal that something needs attention. Instead of immediately heading to the mechanic and facing potentially hefty diagnostic fees, a Subaru Obd2 Scanner empowers you to understand what’s happening under the hood of your vehicle right in your own driveway. These ingenious devices, compatible with all Subaru models from 1996 onwards thanks to the standardized On-Board Diagnostics II (OBD2) system, connect to your car’s computer and translate the complex data into understandable trouble codes.
An OBD2 scanner is essentially your personal automotive translator, accessing the vast network of information your Subaru constantly monitors, from engine temperature to sensor readings. By plugging a scanner into your Subaru’s OBD2 port, you can retrieve these Diagnostic Trouble Codes (DTCs) that trigger the check engine light. While basic scanners will read standard codes, the best Subaru OBD2 scanners go a step further, accessing manufacturer-specific codes, offering a more detailed and accurate diagnosis for your Subaru. Investing in the right scanner can save you time, money, and provide valuable insight into your Subaru’s health. Based on recommendations from the SubaruOutback.org community, we’ve compiled a list of top OBD2 scanners that are worth considering for your Subaru.
1. OBDLink MX+: Subaru Community Favorite for Wireless Diagnostics
The OBDLink brand is highly regarded within the Subaru community, and the MX+ model stands out as a top pick for wireless Subaru OBD2 diagnostics. This Bluetooth-enabled scanner boasts a rapid data transfer rate, providing real-time live data from your Subaru’s engine control unit (ECU) directly to your smartphone or tablet. Unlike many budget Bluetooth scanners limited to Android devices, the OBDLink MX+ is compatible with iOS, Android, and Windows, ensuring broad accessibility. Paired with OBDLink’s free companion app, it offers a user-friendly interface for interpreting diagnostic information. Beyond reading basic OBD2 codes, the MX+ delves into Subaru-specific manufacturer codes, giving you a more comprehensive understanding of potential issues. Its reliable performance and a generous three-year warranty make the OBDLink MX+ a worthwhile investment, and it’s safe to leave plugged into your Subaru’s OBD2 port for continuous monitoring if desired.
2. ScanGauge II: A Versatile OBD2 Scanner and Digital Gauge for Subaru Vehicles
The ScanGauge II distinguishes itself as more than just a Subaru diagnostic scanner; it doubles as an auxiliary gauge display for your Subaru. Compatible with all OBD2 compliant vehicles (1996 and newer), the ScanGauge II performs standard diagnostic functions, including reading and clearing both active and pending trouble codes. However, its unique advantage lies in its ability to display a wealth of real-time vehicle data on a compact, integrated screen. Beyond RPM and speed, the backlit display can show vital Subaru parameters such as intake air temperature, fuel pressure, ignition timing, and coolant temperature. For fuel-conscious Subaru owners, it provides real-time fuel consumption, average MPG, and even calculates cost per mile. Furthermore, the ScanGauge II supports vehicle-specific gauges, allowing you to monitor parameters like boost pressure for turbocharged Subaru models. This blend of diagnostic capability and real-time monitoring makes the ScanGauge II a valuable tool for any Subaru owner.
3. Innova 5610: Advanced Bi-Directional Control Subaru OBD2 Scanner
The Innova 5610 is a step up in Subaru OBD2 scanner functionality, offering both basic and manufacturer-specific code reading, which is essential for comprehensive Subaru diagnostics. Its large color screen enhances user-friendliness, displaying data and trouble codes clearly, and enabling graphical representations of your Subaru’s sensor readings. Beyond standard OBD2 functions, the Innova 5610 can scan virtually every module in your Subaru, including tire pressure monitoring systems (TPMS). A standout feature is its bi-directional control capability. This advanced functionality, typically found in professional-grade tools, allows you to send commands to vehicle modules and sensors – like deactivating a module for testing or commanding an EGR valve to open and close. For the more experienced DIY Subaru mechanic, the Innova 5610’s bi-directional control can significantly streamline diagnostics and problem-solving.
4. BlueDriver Pro: Subaru OBD2 Scanner with Enhanced Repair Information
The BlueDriver Pro is another highly recommended Subaru OBD2 scan tool, lauded for its user-friendliness and comprehensive features. Like others on this list, it reads and clears standard OBD2 trouble codes, and provides freeze frame data, capturing the vehicle’s condition when a code was triggered. It also displays live data streams from your Subaru’s sensors. A particularly useful feature for Subaru owners is the smog check readiness test, indicating if your vehicle has completed all necessary internal tests for emissions testing. The BlueDriver Pro excels with its repair report feature. For each trouble code, it generates a report detailing likely causes, common fixes reported by other vehicle owners, and other helpful information, guiding you towards effective solutions for your Subaru’s issues.
5. Autel AutoLink AL329: Affordable and Reliable Subaru OBD2 Code Reader
Autel is a well-known brand in professional automotive diagnostics, often seen in workshops and garages. While they produce high-end diagnostic systems, the Autel AutoLink AL329 offers a more accessible Subaru OBD2 scanner option for DIYers. This standalone tool is ideal for those who prefer a direct plug-and-play experience without the need for Bluetooth or smartphone apps. While it doesn’t have the advanced features of Autel’s professional-grade MaxiSys tools, the AL329 capably retrieves generic and manufacturer-specific codes, checks emissions readiness, and displays freeze frame data on its color screen. For Subaru owners seeking a reliable and budget-friendly OBD2 scanner to handle basic diagnostics, the Autel AutoLink AL329 is an excellent choice.
