The thrill of owning a Subaru, especially models like the Outback, comes with the promise of adventure and reliability. However, even the most dependable vehicles can sometimes throw a curveball – in the form of a check engine light. That ominous glow on your dashboard can trigger immediate anxiety: Is it a minor hiccup or a major mechanical failure? Instead of rushing to an expensive mechanic for a diagnosis, an OBD 2 scanner empowers you to understand the issue from the comfort of your garage.
An OBD 2 scanner, short for On-Board Diagnostics II scanner, is your key to unlocking the hidden language of your Subaru’s computer system. Since 1996, all vehicles in the U.S., including every Subaru, have been equipped with this standardized system. It meticulously monitors everything from your engine’s temperature to the efficiency of your catalytic converter, relaying crucial data to the Engine Control Unit (ECU). When something deviates from the norm, the check engine light illuminates, and a diagnostic trouble code (DTC) is stored within the system.
Investing in the right OBD 2 scanner for your Subaru means taking control of your vehicle’s health. These devices read the DTCs, giving you a clear indication of the problem area. Basic scanners will decipher standardized codes, while more advanced models can access manufacturer-specific codes, providing even deeper insights into Subaru-specific issues. To guide you in making an informed decision, we’ve consulted the SubaruOutback.org community and compiled a list of highly recommended OBD 2 scanners that are perfect for Subaru vehicles.
1. OBDLink MX+: The Subaru Community’s Top Pick
OBDLink is a reputable brand known for its diverse range of scan tools, and the MX+ stands out as a favorite among Subaru owners. Praised for its rapid Bluetooth connectivity, the MX+ delivers real-time, live data directly from your Subaru’s engine computer to your smartphone or tablet. Unlike many budget Bluetooth scanners limited to Android, the OBDLink MX+ is compatible with iOS, Android, and Windows devices through its free companion app.
Beyond broad compatibility, the OBDLink MX+ excels in diagnostic capabilities. It reads both basic OBDII codes and manufacturer-specific codes, providing in-depth diagnostics for your Subaru. Its reliable performance is further backed by a three-year warranty. Convenience is also a key feature; the MX+ is designed to be safely left plugged into your Subaru’s OBD 2 port, allowing for continuous monitoring and easy access whenever you need it.
2. ScanGauge II: More Than Just a Subaru OBD 2 Scanner
The ScanGauge II distinguishes itself as a multifaceted tool, functioning as both an OBD 2 scanner and an auxiliary gauge display for your Subaru. Compatible with all OBDII-compliant vehicles (1996 and newer), it performs standard diagnostic functions like reading and clearing both current and pending trouble codes.
However, the ScanGauge II goes beyond basic diagnostics by offering real-time monitoring of various vehicle parameters. Its compact screen can display trip computers, performance metrics, and a range of gauges. Monitor crucial data such as RPM, speed, intake air temperature, fuel pressure, ignition timing, and coolant temperature. For the fuel-conscious Subaru owner, it provides instantaneous and average fuel economy readings, even calculating cost per mile. Furthermore, vehicle-specific gauges, including a boost gauge for turbocharged Subarus, are available, offering enthusiasts a deeper dive into their vehicle’s performance data.
3. Innova 5610: Advanced Diagnostics for the Subaru DIY Enthusiast
The Innova 5610 is a robust OBD 2 scanner that covers the essential diagnostic needs of Subaru owners, including reading both basic and manufacturer-specific trouble codes. Its large, color display enhances user-friendliness, making it easy to interpret data and trouble codes, and even visualize live data streams through graphs. The Innova 5610 offers comprehensive scanning capabilities, reaching into nearly every module of your Subaru, including the tire pressure monitoring system (TPMS).
What truly elevates the Innova 5610 is its bidirectional control functionality, a feature typically found in professional-grade scan tools used by dealership technicians. This advanced capability allows you to interact with your Subaru’s modules and sensors. You can isolate modules for testing purposes or command components like the EGR valve to activate, enabling thorough diagnostics and problem-solving for the more experienced DIY mechanic tackling complex Subaru issues.
4. BlueDriver Pro: Smart Subaru Diagnostics via Your Smartphone
The BlueDriver Pro stands out as another highly recommended OBD 2 scanner, especially for its seamless smartphone integration. Like the other scanners on our list, it expertly reads, interprets, and clears all standard OBDII trouble codes and goes further by capturing freeze frame data, providing a snapshot of vehicle conditions when a trouble code was triggered. It also displays live data, offering a real-time view of your Subaru’s sensor readings.
A particularly valuable feature for Subaru owners is the BlueDriver Pro’s smog check readiness verification. Resetting trouble codes can make your Subaru fail an emissions test initially, and BlueDriver Pro accurately indicates when your vehicle has completed all necessary internal tests and is ready for inspection. Furthermore, BlueDriver Pro generates repair reports for each trouble code, offering likely causes, owner-reported fixes, and other valuable information to streamline your diagnostic and repair process for your Subaru.
5. Autel AutoLink AL329: Professional-Grade Subaru Diagnostics for the DIYer
Autel is a recognized name in professional automotive diagnostics, frequently seen in workshops and on mechanic YouTube channels.
