To clear Subaru fault codes, you can use an OBD-II scanner. Connect the scanner to the OBD-II port in your Subaru, usually located beneath the dashboard. Turn on the ignition without starting the engine. Navigate through the scanner’s menu to find the “Clear Codes” option and select it. This will erase the fault codes from the vehicle’s computer.
Ensure your Subaru meets the criteria for clearing codes, such as resolving the underlying issue triggering the fault codes. Keep in mind that clearing codes doesn’t fix the problem; it only resets the system.
What Are Subaru Fault Codes?
Subaru fault codes, also known as OBD-II trouble codes, are diagnostic codes used by Subaru vehicles to indicate issues within the vehicle’s systems. These codes help mechanics and technicians identify specific problems when a vehicle’s onboard computer detects an abnormality.
Common Subaru fault codes include P0420 (Catalyst System Efficiency Below Threshold), P0300 (Random/Multiple Cylinder Misfire Detected), and many others.
To get the exact meaning of a specific code, a Subaru OBD-II code reader or scan tool is required to access the vehicle’s onboard computer.

Why Do You Need to Clear Subaru Fault Codes?
Clearing Subaru fault codes is often necessary for various reasons:
- Diagnostic Reset: Clearing codes allows for a fresh diagnostic cycle. Once an issue is addressed, clearing the codes helps verify if the problem is resolved, ensuring the system is functioning properly.
- Indicator Lights: Fault codes trigger warning lights on the dashboard. Clearing the codes turns off these lights, preventing unnecessary distractions and potential confusion for the driver.
- Emissions Testing: In some regions, vehicles must pass emissions tests. Clearing fault codes after addressing issues ensures the vehicle meets emission standards during testing.
- Performance Monitoring: Clearing codes can help monitor the vehicle’s ongoing performance. If new issues arise, fresh fault codes will be generated, indicating areas that need attention.
- System Adaptation: Modern vehicles adapt to driving conditions. Clearing fault codes may allow the vehicle’s systems to relearn and adapt to changes, optimizing performance.
- Maintenance Records: Clearing codes and resolving issues contribute to accurate maintenance records. It helps keep track of when and how problems were addressed, aiding in future diagnostics.
