Seeing your Subaru’s brake light flashing and the check engine light on can be alarming. These warning lights indicate issues that require immediate attention.
Understanding what these lights mean is crucial for your vehicle’s health. The brake light may suggest a problem with the braking system, while the check engine light often points to issues under the hood. Ignoring these warnings could lead to serious damage and expensive repairs.
In this blog post, we’ll explore the common reasons these lights might appear. We will also discuss the steps you should take to address these issues. This knowledge can help you keep your Subaru running smoothly and safely. So, let’s dive in and learn more about these important warning lights.
Common Causes
Seeing the brake light flashing and the check engine light on in your Subaru can be alarming. Understanding the common causes can help you address these issues promptly. Let’s delve into some of the most typical reasons why these warning lights might appear on your dashboard.
Electrical Issues
Electrical problems are a frequent cause of the brake light flashing and the check engine light coming on. A loose or damaged wire can disrupt the electrical circuit, leading to warning lights. Faulty fuses can also trigger these indicators. Regular maintenance of the car’s electrical system helps prevent these issues.
Sensor Malfunctions
Sensors play a crucial role in monitoring your car’s functions. A malfunctioning sensor can cause the brake light to flash and the check engine light to turn on. For instance, the brake fluid sensor might detect low fluid levels incorrectly. Similarly, the oxygen sensor in the engine might send faulty signals. Replacing faulty sensors can often resolve these problems.

Diagnostic Process
The diagnostic process for a Subaru brake light flashing and check engine light can seem daunting. However, it becomes manageable when broken down into clear steps. Identifying the issue quickly and accurately can save time and prevent further damage. Below are key steps to start the diagnostic process.
Reading Error Codes
First, use an OBD-II scanner to read error codes from your Subaru. This tool connects to the car’s diagnostic port, typically found under the dashboard. Once connected, it reads the codes stored in the car’s computer. These codes provide clues about the issues causing the warning lights to activate.
Write down the codes for reference. Each code corresponds to a specific problem area. For example, a P0420 code indicates a catalyst system efficiency issue. Understanding these codes is crucial. You can then research or consult a professional for detailed insights.
Inspecting Wiring
Next, inspect the wiring connected to the brake system and engine. Damaged or loose wires can trigger warning lights. Check for any visible signs of wear or damage. Also, ensure all connections are secure and intact.
Pay attention to the battery connections as well. A weak or corroded battery can cause multiple issues. Clean any corrosion and ensure the battery terminals are tight. If the wiring appears intact, move on to checking other components.
Immediate Steps To Take
Seeing your Subaru’s brake light flashing and the check engine light on can be alarming. Knowing the right steps can ensure your safety and minimize damage. Here are immediate actions you should take.
Safety Precautions
Your safety is the top priority. Follow these steps:
- Pull over to a safe location. Avoid stopping on busy roads.
- Turn on your hazard lights to alert other drivers.
- Engage the parking brake to prevent rolling.
- Stay inside the car if you are in a dangerous area.
Ensuring safety is crucial before addressing any car issues.
Temporary Fixes
Once safe, you can try these temporary fixes:
- Check the Brake Fluid Level: Low brake fluid can trigger the brake light. Refill if needed.
- Inspect Brake Pads: Worn-out brake pads can cause the brake light to flash. Replace if necessary.
- Check Engine Codes: Use an OBD-II scanner to check for engine codes. This can give clues about the issue.
These fixes can help you understand the problem and decide the next steps.
If the problem persists, seek professional help. Continuing to drive can cause further damage.
