The check engine light in your Subaru Outback can be a source of stress, signaling potential problems from minor to significant. Instead of immediately heading to a mechanic and incurring diagnostic fees, an OBD2 scanner empowers you to understand what’s going on under the hood of your Outback. These devices, compatible with all Subaru Outbacks manufactured since 1996 due to the standardized On-Board Diagnostics II (OBD2) protocol, plug into your car’s diagnostic port and retrieve data from its computer system. This data includes crucial Diagnostic Trouble Codes (DTCs) that trigger the check engine light.
Investing in the right OBD2 scanner for your Subaru Outback can save you time and money by allowing you to diagnose issues yourself. While basic scanners read standard codes, more advanced options can access manufacturer-specific codes, providing deeper insights into your Subaru’s health. Based on recommendations from the SubaruOutback.org community, we’ve compiled a list of top OBD2 scanners worth considering for your Subaru Outback.
1. OBDLink MX+: SubaruOutback.org Community’s Top Choice
OBDLink is a respected brand in the OBD2 scanner market, and the MX+ model stands out as a favorite among Subaru Outback owners. Praised for its rapid Bluetooth connectivity, the OBDLink MX+ delivers real-time, live data directly from your Subaru’s engine computer to your smartphone or tablet. Unlike some budget Bluetooth scanners limited to Android devices, the OBDLink MX+ is compatible with iOS, Android, and Windows via free companion apps.
Beyond compatibility, the OBDLink MX+ excels in functionality. It reads both basic and manufacturer-specific diagnostic codes, giving you a comprehensive understanding of any issues your Subaru Outback might be experiencing. Its reliability is further enhanced by a three-year warranty, and its energy-efficient design allows it to remain safely plugged into your Outback’s OBD2 port without draining the battery.
2. ScanGauge II: More Than Just a Subaru Outback OBD2 Scanner
The ScanGauge II offers a unique proposition: it’s not just an OBD2 scanner for your Subaru Outback, but also a customizable gauge display. Compatible with all 1996 and newer OBD2 vehicles, including your Subaru Outback, the ScanGauge II performs standard diagnostic functions, reading and clearing both current and pending trouble codes.
However, what sets the ScanGauge II apart is its ability to function as an auxiliary gauge cluster. Its compact screen can display a wealth of real-time vehicle data, including RPM, speed, intake air temperature, fuel pressure, ignition timing, coolant temperature, and more. For Subaru Outback owners focused on fuel efficiency, it can also display instantaneous and average fuel consumption, and even calculate cost per mile. Furthermore, the ScanGauge II supports vehicle-specific gauges, potentially including boost pressure monitoring for turbocharged Subaru Outback models if supported.
3. Innova 5610: Advanced Diagnostics for the Subaru Outback DIYer
The Innova 5610 OBD2 scanner is designed for Subaru Outback owners who want to go beyond basic code reading. While it handles generic and manufacturer-specific trouble codes effectively, as expected from a quality scanner, the Innova 5610 distinguishes itself with advanced features. It boasts a large, color display for easy viewing of data and code information, and can also graph live data streams from your Subaru’s sensors. It extends its diagnostic reach to nearly all modules in your Subaru Outback, including tire pressure monitoring systems (TPMS).
The key feature that elevates the Innova 5610 is its bidirectional control capability. This advanced functionality, typically found in professional-grade scanners used by dealership technicians, allows you to send commands to vehicle modules and sensors. For example, you can temporarily disable a module for isolated testing or command an EGR valve to open and close to verify its operation during troubleshooting. This makes the Innova 5610 a powerful tool for experienced DIY mechanics working on their Subaru Outbacks.
4. BlueDriver Pro: Subaru Outback OBD2 Scanner with Repair Guidance
The BlueDriver Pro is another highly recommended OBD2 scan tool for Subaru Outback owners, known for its user-friendly interface and helpful repair information. Like the other scanners on this list, it reads, interprets, and clears standard OBD2 trouble codes. It also captures freeze frame data, providing a snapshot of vehicle conditions when a code was triggered, and displays live sensor data for real-time monitoring. Furthermore, the BlueDriver Pro can assess your Subaru Outback’s emissions system readiness for smog or emissions testing, a valuable feature after clearing codes.
A standout feature of the BlueDriver Pro is its repair report function. For each trouble code, the BlueDriver app can generate a repair report detailing potential causes, common fixes reported by other vehicle owners, and other diagnostic tips. This guided approach makes the BlueDriver Pro particularly helpful for Subaru Outback owners who are newer to DIY car repair and diagnostics.
5. Autel AutoLink AL329: Affordable and Reliable Subaru Outback OBD2 Diagnostics
Autel is a well-known name in professional automotive diagnostic tools, often seen in workshops and garages. While they produce high-end diagnostic systems, Autel also offers more accessible options for DIYers, like the AutoLink AL329. This standalone OBD2 code reader is ideal for Subaru Outback owners who prefer a dedicated device without the need for Bluetooth pairing or smartphone apps – simply plug it in and diagnose.
The Autel AutoLink AL329 features a color display for clear code and data viewing. It retrieves generic and manufacturer-specific codes, checks emissions readiness status, and displays freeze frame data. While it may not have all the advanced features of higher-end scanners, the AL329 provides essential OBD2 diagnostic capabilities for your Subaru Outback at a very budget-friendly price point, making it a great entry-level option.
Having an OBD2 scanner is a valuable tool for any Subaru Outback owner. It allows you to take control of your vehicle’s diagnostics, understand check engine light issues, and potentially save money on unnecessary mechanic visits. Whether you choose a basic code reader or a more advanced scan tool with features like bidirectional control or repair reports, investing in an OBD2 scanner is a smart move for maintaining your Subaru Outback.
