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?
Let’s start with the basics. Subaru fault codes are like secret messages your car sends to tell you when something isn’t quite right. Just like how your tummy grumbles when it’s hungry, your car’s computer grumbles with fault codes when something’s wrong.
Typically. Subaru fault codes are specific error messages that the computer system in your car generates to indicate a potential problem. These codes help technicians diagnose and fix issues more efficiently. Here’s a breakdown:
What they are:
- Standardized alphanumeric codes (e.g., P0101, B1234)
- Stored in the car’s On-Board Diagnostic (OBD) system
- Triggered when a sensor detects an abnormality in various systems (engine, transmission, emissions, etc.)
Types of codes:
- Generic OBD-II codes: These are standardized codes used by most car manufacturers, including Subaru. They cover a wide range of issues, from engine problems to emission control malfunctions.
- Manufacturer-specific codes: These are unique codes specific to Subaru vehicles and provide more detailed information about the problem.
How do Subaru Fault Codes Work?
Before approaching to clear your Subaru Fault Codes, it’s essential to know how they work.
- Each code corresponds to a specific issue or component
- Different code categories exist (e.g., P for powertrain, B for body)
- The first digit indicates the system involved (e.g., P for powertrain, B for body)
- The second digit is generic (e.g., 0 for general, 1 for fuel/air metering)
- The third and fourth digits are manufacturer-specific
What do They Tell You?
- Not a definitive diagnosis: They point to a potential issue area, not the exact problem.
- Severity can vary: Some codes indicate minor issues, while others signal major problems.
- Need for further investigation: A technician will use the code and other diagnostic tools for a proper diagnosis.
How Can You Access Them?
When your car diagnoses a fault, they show it on your car display. You can access those codes in the following ways:
- Check engine light: If illuminated, it usually means a fault code is stored.
- OBD-II scanner: A handheld device that can read and display the codes.
- Manual retrieval: Some Subaru models allow you to retrieve codes manually using a specific button sequence on the dashboard. Refer to your owner’s manual for details.
- Professional mechanics or Subaru dealerships: They have advanced diagnostic tools and expertise to interpret the codes and fix the issue.
Why Do You Need to Clear Subaru Fault Codes?
Imagine if you spilled milk on the floor but never cleaned it up. It would get all sticky and gross, right? Well, leaving fault codes unclear is a bit like that. It can make your car’s brain confused and cause more problems down the road.
- Don’t ignore fault codes. Ignoring them can lead to more significant problems and costly repairs.
- Do your research. If you’re comfortable with basic car maintenance, you can research the code online or in repair manuals to understand the potential issue better. However, remember that DIY repairs can be complex and risky, so proceed with caution.
- Consult a mechanic. While some basic codes might have online explanations, a qualified mechanic is crucial for accurate diagnosis and repair.
- Provide the code to the mechanic. This helps them start troubleshooting faster and more effectively.

Can You Clear Subaru Fault Codes Without Tools?
Hmm, what if you don’t have an OBD-II scanner? Don’t worry; there are some tricks you can try, but having the right tool makes it much easier.
Let’s find the video below for the hacks on how to clear Subaru fault codes without any tools like OBDII.
Common Mistakes to Avoid
Oopsie daisies! Sometimes we make mistakes, but don’t worry; I’ll tell you some common ones to avoid so you can clear those codes like a pro.
Here are some common mistakes that you should avoid while clearing the fault codes on your Subaru.
- Clearing Without Diagnosis: Clearing fault codes without diagnosing and addressing the underlying issue can lead to a recurrence of the problem. Always diagnose and fix the root cause before clearing codes.
- Ignoring Other Warning Lights: Fault codes are often accompanied by warning lights on the dashboard. Ignoring other warning lights may overlook additional issues that require attention.
- Disconnecting the Battery Improperly: Disconnecting the battery to clear fault codes can reset the vehicle’s systems, but it may also cause the loss of important settings and data. If using this method, ensure you have access to the necessary codes and systems after reconnection.
- Clearing Codes Without Repair: Simply clearing fault codes without addressing the underlying problem may result in a temporary resolution but could lead to recurring issues later on. Always diagnose and repair the root cause of the fault before clearing codes.
- Incomplete Clearing Process: Ensure that the fault codes are properly cleared by following the manufacturer’s recommended procedure. Skipping steps or prematurely disconnecting diagnostic tools can lead to incomplete clearing.
- Using an Incorrect Diagnostic Tool: Using an incompatible or low-quality diagnostic tool may not effectively clear fault codes or could potentially cause damage to the vehicle’s systems. Always use a reputable and compatible diagnostic tool recommended for Subaru vehicles.
- Not Verifying Clearing: After clearing fault codes, always verify that the codes have been successfully erased and ensure that the warning lights associated with the fault codes are no longer illuminated.
By avoiding these common mistakes, you can effectively clear fault codes on your Subaru vehicle and ensure the proper functioning of its systems.
