How to verify and confirm the issue

Verifying the cause of your 2022 Forester EyeSight system warning involves a combination of visual checks, practical tests, and potentially using a diagnostic scan tool.

• Visual Inspection:
  • Windshield Clarity: Carefully inspect the windshield area in front of the EyeSight cameras (located at the top center of the windshield, behind the rearview mirror). Look for dirt, ice, snow, condensation, stickers, or any obstructions that might block the cameras' view.
  • Windshield Damage: Check for cracks, chips, or pitting in the windshield, especially in the camera's field of view. Even minor damage can interfere with the system.
  • Recent Windshield Replacement: If the windshield was recently replaced, confirm it was an OEM-approved, EyeSight-compatible windshield and that it was properly installed and calibrated. Improper installation or lack of calibration is a frequent cause of malfunctions.
• Practical Driver Checks:
  • Environmental Factors: Note if the warning appears only under specific conditions (heavy rain, bright sun, fog). The system is designed to temporarily disable itself in these scenarios for safety.
  • Vehicle Restart: Sometimes, turning the vehicle off, waiting a few minutes, and restarting it can clear a temporary glitch.
• Scan Tool Use:
  • Connect an OBD-II scanner to the vehicle's diagnostic port. Check for Diagnostic Trouble Codes (DTCs) in the EyeSight control module, engine control module (ECM), and other related systems. Common codes might include communication errors (e.g., U0100, U0121) or specific EyeSight-related codes (e.g., C1441, B1700 series). For more information on interpreting these codes, you can refer to our Browse OBD-II codes section.
  • Monitor live data from the EyeSight system, if your scanner supports it, to check camera status, voltage, and communication signals.
• Known TSBs: Research any Technical Service Bulletins (TSBs) issued by Subaru for the 2022 Forester that relate to EyeSight system warnings or malfunctions. These can often point to known issues and their official solutions.

Common causes (most likely first)

Understanding the most frequent culprits behind a 2022 Forester EyeSight system warning can help narrow down your diagnostic efforts:

• Environmental Obstructions: The most common cause. Heavy rain, snow, dense fog, direct sunlight, or even shadows can temporarily blind the cameras, causing the system to disable itself.
• Physical Obstructions on Windshield: Dirt, ice, snow, leaves, bugs, or even a car wash sticker on the windshield in front of the cameras can block their view.
• Windshield Damage or Improper Replacement: Cracks, chips, or a non-OEM or improperly installed/calibrated windshield will disrupt the camera's ability to accurately perceive its surroundings.
• Low Battery Voltage: A weak or failing 12V battery can cause various electronic systems, including EyeSight, to malfunction or generate false warnings due to insufficient power.
• Communication Errors: Faults in the wiring or communication network between the EyeSight control module and other vehicle systems (like the ECM or ABS module) can trigger warnings.
• Software Glitches: Occasionally, a temporary software bug can cause the system to fault. A vehicle restart sometimes resolves this.
• Faulty EyeSight Camera Unit: While less common, an internal malfunction within one of the stereo cameras can necessitate replacement. This is typically a last resort after ruling out other causes.
• Misaligned Cameras: If the vehicle has been in an accident or had front-end work, the cameras might be physically misaligned, requiring professional calibration.
