When the high-speed ETC display is abnormal, there are usually problems such as failure to recognize the license plate and untimely data transmission due to too fast speed. The following describes how to solve these problems.
Causes and solutions for license plate recognition failures
The failure of license plate recognition may be due to the signal between the license plate and the ETC server being blocked, resulting in unstable data transmission. In this case, you can try to turn off the power of the ETC server and check if the distance between the license plate and the ETC server is too far. If the distance is too far, it is recommended to move the license plate closer to the ETC server, or contact ETC customer service for troubleshooting.
The failure of license plate recognition may be due to the ETC label on the license plate being damaged or dirty, resulting in the ETC server not being able to recognize the license plate number. In this case, you can try to use a professional cleaning tool to clean the ETC label on the license plate, or contact ETC customer service to replace the label.
The failure of license plate recognition may be due to electromagnetic interference in the signal between the license plate and the ETC server, resulting in unstable data transmission. In this case, you can try to turn off the power of the ETC server and check if the distance between the license plate and the ETC server is too far. If the distance is too far, it is recommended to move the license plate closer to the ETC server, or contact ETC customer service for troubleshooting.
Causes and solutions for untimely data transmission caused by excessive speed
The data transmission is not timely due to the speed being too fast, which may be due to the distance between the license plate and the ETC server, resulting in unstable data transmission speed. In this case, you can try to increase the distance between the license plate and the ETC server, or contact ETC customer service for troubleshooting.
The data transmission is not timely, which may be due to the ETC tag on the license plate being damaged or dirty, resulting in the ETC server not being able to recognize the license plate number. In this case, you can try to use a professional cleaning tool to clean the ETC label on the license plate, or contact ETC customer service to replace the label.
The delay in data transmission due to the speed is too fast may be due to an obstacle between the license plate and the ETC server, resulting in unstable data transmission. In this case, you can try to move the vehicle or clear the obstacles around the vehicle, or contact ETC customer service for troubleshooting.
