Remember, this information is for general guidance only; professional diagnosis is always recommended.

Understanding the Subaru Eyesight System and Potential Issues

Subaru's Eyesight system is a suite of advanced driver-assistance features that rely on cameras and sensors. These components are crucial for functions like:

• Adaptive Cruise Control (ACC): Maintains a set distance from the vehicle ahead.
• Pre-Collision Braking (PCB): Automatically applies the brakes to avoid or mitigate collisions.
• Lane Keep Assist (LKA): Helps keep the vehicle within its lane.
• Lane Departure Warning (LDW): Alerts the driver if the vehicle is drifting out of its lane.

A malfunction in any of these components can trigger the check engine light and disable Eyesight features. Common causes include:

Potential Causes of Check Engine Light and Eyesight Malfunctions:

• Dirty or Obstructed Sensors: Dust, dirt, snow, or ice can accumulate on the Eyesight cameras and sensors, hindering their performance.
• Faulty Cameras or Sensors: Over time, these components can wear out or become damaged.
• Software Glitches: Sometimes, a simple software reset might resolve the issue.
• Wiring Problems: Damaged or loose wiring can disrupt the Eyesight system's functionality.
• Low Windshield Washer Fluid: Surprisingly, insufficient washer fluid can trigger an error.
• Calibration Issues: The Eyesight system may need recalibration after certain repairs or impacts.

Troubleshooting Steps: A DIY Approach

Before rushing to the dealership, try these troubleshooting steps:

1. Clean the Eyesight Cameras and Sensors:

Carefully clean the cameras and sensors located behind the rearview mirror using a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners.

2. Check the Windshield Washer Fluid:

Ensure your windshield washer fluid level is sufficient. Low fluid can interfere with sensor function.

3. Check for Obstructions:

Inspect the area around the cameras and sensors for any obstructions, such as stickers or debris.

4. Restart Your Vehicle:

A simple restart can sometimes resolve temporary software glitches.

5. Check the Owner's Manual:

Your owner's manual may provide specific troubleshooting information for Eyesight system errors. It may include codes displayed related to the malfunction.

When Professional Help is Needed

If the check engine light persists after these steps, it's crucial to seek professional help. A Subaru dealership or qualified mechanic can properly diagnose the issue using specialized diagnostic tools. Ignoring the problem could lead to more significant damage or safety risks. They can pinpoint the exact cause, whether it's a faulty sensor, wiring problem, or a more complex mechanical issue.
