Regarding the Electronic Transmission (ET) Network, which statement is correct?

• A. The ET Network allows the EIS/OIS to automatically connect to the Vehicle Information Database.
• B. ET Network stores customer data locally on the station computer.
• C. ET Network provides user authentication for the LEM system.
• D. The ET Network automatically downloads repair manuals.

Answer: (A)

The ET Network links the emission testing equipment to a centralized Vehicle Information Database so vehicle data can be retrieved automatically. When the EIS/OIS reads a VIN, the ET Network queries the Vehicle Information Database and fills in the vehicle’s details, ensuring the test uses the correct information and reducing manual entry errors.

This isn’t about storing customer data locally at the station, nor is it primarily for authenticating users of the LEM system, and it isn’t designed to automatically download repair manuals. The strength of the ET Network lies in providing real-time access to centralized vehicle data to support accurate and efficient inspections.
