ER-DA
Mobileye ADAS Collision Warning System
Severity: ModerateWhat Does This Error Mean?
ER-DA on a Mobileye unit means the system has detected a tamper condition — the camera is either physically obstructed, has been moved from its calibrated position, or the system suspects the camera has been deliberately covered. ER-DA disables the collision warning system until the condition is cleared.
Affected Models
- Mobileye 6 Series
- Mobileye 8 Connect
- Mobileye Shield+
- Mobileye 630
- Mobileye 650
Common Causes
- Camera lens obstructed — sticker, tape, suction cup, or accessory placed in front of the lens
- Camera moved from its original mounting position on the windshield
- Windshield very dirty or fogged directly in front of the camera
- Camera deliberately covered — e.g., by a driver wishing to disable the system
- Camera mounting bracket loose — camera pointing at wrong angle
How to Fix It
-
Inspect the camera lens for obstructions.
Check that nothing is directly in front of or stuck to the Mobileye camera lens. Common culprits: parking permits or registration stickers placed on the inside of the windshield near the camera, toll transponders, dashcam mounts, or air fresheners hanging from the mirror.
-
Clean the windshield area directly in front of the camera.
Dirt, rain streaks, tree sap, or ice on the windshield in the camera's field of view can trigger ER-DA. Clean the windshield from outside and also clean the inside of the glass where the camera looks through.
-
Check the camera mounting bracket.
The Mobileye camera should be firmly attached to the windshield via its adhesive mount and pointing forward at the correct angle. If the bracket has come loose or the camera has rotated, the ER-DA flag may indicate the camera angle is outside the acceptable range.
-
If the camera position or bracket has changed, arrange recalibration.
After any camera repositioning, the Mobileye system requires recalibration by an authorised Mobileye installer. Driving without recalibration will result in unreliable or absent warnings.
Frequently Asked Questions
Can ER-DA appear in bright sunlight?
Yes — very intense direct sunlight shining into the camera can temporarily saturate the image sensor, causing ER-DA. This is most common at sunrise or sunset when driving directly toward the sun. The error should clear automatically once the lighting conditions change.
Can a driver disable Mobileye by triggering ER-DA deliberately?
Covering the camera will trigger ER-DA and disable warnings, but fleet management systems that are connected to Mobileye 8 Connect log all ER-DA events with timestamps. Fleet managers can see when and how long the camera was obstructed.
