ER-16
Mobileye ADAS Collision Warning System
Severity:What Does This Error Mean?
ER-16 on a Mobileye unit means the EyeQ processor cannot communicate with the camera's image sensor. The camera module contains both the lens/sensor assembly and the EyeQ processing chip — when the communication between these fails, ER-16 is displayed and the system stops providing collision warnings. ER-16 is an internal hardware fault that typically requires camera unit replacement.
Affected Models
- Mobileye 6 Series
- Mobileye 8 Connect
- Mobileye Shield+
- Mobileye 630
- Mobileye 650
Common Causes
- Camera unit internal hardware failure — image sensor or EyeQ processor chip fault
- Camera cable damaged or connector loose at the camera unit
- Power supply to the camera unit unstable or insufficient
- Physical damage to the camera — impact, water ingress, or sun damage to the unit
How to Fix It
-
Check the camera cable connection.
Locate the cable running from the Mobileye camera unit (mounted on the windshield) to the EyeWatch display unit or junction box. Verify the connector is firmly seated at both ends. A cable that has been partially pulled out by a door, sun visor, or cleaning will cause ER-16.
-
Inspect the camera unit for physical damage.
Check the camera for cracks, moisture inside the lens area, or signs of impact. Mobileye cameras can be damaged by aggressive windshield cleaning, car washes, or objects hitting the windshield.
-
Power cycle the vehicle — turn off the ignition, wait 30 seconds, restart.
A transient communication fault caused by a brief voltage spike may clear after a full power cycle. If ER-16 clears and the Mobileye system shows normal operation, monitor it closely — if it returns, the camera unit is failing.
-
If ER-16 persists, arrange camera unit replacement.
Contact a Mobileye authorised installer or your fleet management service. Provide the Mobileye unit model and the vehicle details.
When to Call a Professional
ER-16 requires a Mobileye authorised installer or fleet service technician. The camera unit is a sealed assembly — it cannot be repaired in the field and must be replaced if the fault is confirmed.
Frequently Asked Questions
What is the EyeQ processor in a Mobileye camera?
The EyeQ is Mobileye's proprietary image processing chip built into the camera unit. It analyses the camera image in real time to detect vehicles, pedestrians, lane markings, and other hazards. When EyeQ cannot communicate with the image sensor on the same board, ER-16 is the result.
Can ER-16 appear after a windshield replacement?
Yes — during windshield replacement, the camera unit is removed and reinstalled. If the camera cable connector was not fully reseated after reinstallation, ER-16 will appear. Always have the Mobileye system tested after any windshield work.
