That adventurous Subaru Outback is your trusty companion for exploring, not for endless garage time fixing issues. But even the most reliable vehicles can sometimes flash that dreaded check engine light. When it appears on your dashboard, it’s a signal that something isn’t quite right under the hood – or perhaps with your fuel system, sensors, or any of the myriad components in your car.
Facing a check engine light leaves you with two main options: a potentially costly and time-consuming visit to the dealership, or taking control into your own hands with an OBD2 scanner. An OBDII scanner, leveraging the standardized On-Board Diagnostic II system present in every car sold in the US since 1996, is your direct line into your Subaru’s internal computer network. This network constantly transmits data from various sensors – from air intake temperature to how your water pump is performing – to the Engine Control Unit (ECU) for analysis and adjustments.
The right OBD2 scanner empowers you to access this wealth of data, including standardized Diagnostic Trouble Codes (DTCs) that trigger the check engine light. Even more advanced scanners can delve deeper, reading manufacturer-specific codes to provide even more granular insights into your Subaru Outback’s health. While advanced capabilities come at a higher price, they can be invaluable for pinpointing complex issues.
To guide you in choosing the best tool for your needs, we’ve compiled recommendations based on feedback from the SubaruOutback.org community, highlighting scanners that are truly worth the investment.
1. OBDLink MX+ – SubaruOutback.org Community Top Pick
OBDLink is a well-regarded brand in vehicle diagnostics, and the MX+ model stands out as a community favorite. Its key strength is a rapid Bluetooth connection, allowing for seamless real-time data streaming from your Subaru’s engine computer to your smartphone or tablet. OBDLink provides a free, user-friendly app compatible with iOS, Android, and Windows devices – a significant advantage over many budget Bluetooth scanners that often restrict compatibility to Android.
Beyond universal OBDII compatibility across all vehicles, including your Subaru Outback, the OBDLink MX+ reads both basic and manufacturer-specific trouble codes. This deeper diagnostic capability can be crucial for accurately identifying issues unique to Subaru vehicles. Backed by a 3-year warranty and designed for safe, continuous connection to your vehicle’s OBDII port, the OBDLink MX+ is a reliable and feature-rich choice.
2. ScanGauge II – More Than Just a Scanner for Your Subaru Outback
The ScanGauge II distinguishes itself by serving as both a diagnostic scanner and an auxiliary gauge display for your Subaru Outback. Compatible with all OBDII-compliant vehicles (1996 and newer), it performs standard diagnostic functions such as reading and clearing both active and pending trouble codes. However, its unique appeal lies in its ability to display a wide array of real-time vehicle data on a compact screen.
Beyond basic diagnostics, the ScanGauge II functions as a multi-trip computer, performance monitor, and customizable gauge pod. The backlit display can show essential readings like RPM and vehicle speed, alongside more detailed data such as intake air temperature, fuel pressure, and coolant temperature. For fuel-conscious Outback owners, it can also display instantaneous and average fuel economy, and even calculate cost per mile. With support for vehicle-specific gauges, including boost pressure, the ScanGauge II offers a comprehensive view of your Subaru’s performance and health.
3. Innova 5610 – Advanced Diagnostics for the Subaru Outback DIYer
The Innova 5610 delivers comprehensive diagnostic capabilities, handling both generic OBDII codes and manufacturer-specific codes for your Subaru Outback. It features a large, color display for easy reading of data and trouble codes, along with graphing capabilities to visualize your Subaru’s sensor readings. The Innova 5610 extends its reach beyond basic systems, capable of scanning modules like tire pressure monitoring systems.
What sets the Innova 5610 apart is its bidirectional control functionality, typically found in professional-grade scan tools. This advanced feature allows you to send commands to vehicle modules and sensors, similar to a dealership technician. For instance, you can temporarily disable a module for isolated testing or command an EGR valve to open and close to verify its operation. While these are advanced features, they provide experienced DIY mechanics with powerful diagnostic tools to effectively troubleshoot and resolve complex Subaru Outback issues.
4. BlueDriver Pro – Smart Subaru Outback Diagnostics via Smartphone
The BlueDriver Pro is another highly recommended OBD2 scanner that leverages the power of your smartphone. Like the other scanners on our list, it reads, interprets, and clears standard OBDII trouble codes. It enhances diagnostics with freeze frame data, capturing the vehicle parameters at the moment a trouble code was triggered, and live data streaming for real-time sensor monitoring. The BlueDriver Pro also assists with emissions readiness testing, indicating whether your Subaru Outback has completed the necessary internal tests after code resets.
A standout feature of the BlueDriver Pro is its repair report generation for each trouble code. These reports offer valuable insights, including likely causes, owner-reported fixes, and other troubleshooting information, significantly aiding in problem resolution for your Subaru Outback. This feature makes the BlueDriver Pro particularly user-friendly, guiding you through the diagnostic and repair process.
5. Autel AutoLink AL329 – Reliable and Affordable Subaru Outback Diagnostics
Autel is a respected name in professional automotive diagnostic equipment, frequently seen in workshops and on mechanic YouTube channels. While they offer high-end, comprehensive diagnostic systems, Autel also provides accessible options for the DIY enthusiast. The AutoLink AL329 is a standalone handheld scanner, ideal for users who prefer a dedicated tool without the need for Bluetooth pairing or smartphone apps – simply plug in and diagnose your Subaru Outback.
While Autel’s professional-grade MaxiSys systems boast near-factory level capabilities, including advanced driver-assistance system reprogramming, the AL329 focuses on core diagnostic functions at an affordable price point. It features a color display for easy readability and retrieves both generic and manufacturer-specific codes, displays emissions readiness status, and freeze frame data. For Subaru Outback owners seeking a straightforward, reliable OBD2 scanner to handle basic diagnostics without breaking the bank, the Autel AutoLink AL329 is an excellent choice.
Choosing the Right OBD2 Scanner for Your Subaru Outback
Selecting the ideal OBD2 scanner for your Subaru Outback depends on your technical expertise, budget, and desired features. For basic check engine light diagnosis and code clearing, any of the scanners listed will suffice. If you prefer a user-friendly Bluetooth interface and smartphone integration, the OBDLink MX+ or BlueDriver Pro are excellent choices. For a standalone device with gauge monitoring capabilities, the ScanGauge II is a unique option. If you’re a more advanced DIYer seeking bidirectional control and deeper diagnostics, the Innova 5610 provides professional-level features. Finally, for a reliable and budget-friendly handheld scanner from a reputable brand, the Autel AutoLink AL329 is a strong contender.
By investing in an OBD2 scanner, you can proactively maintain your Subaru Outback, confidently diagnose check engine lights, and potentially save significant money on unnecessary dealership visits. Take control of your car’s health and enjoy more worry-free adventures on the road.
