Which device enables remote diagnostics over the Internet?

• A. OnStar module
• B. Bluetooth dongle
• C. USB drive
• D. AsTech transmitter

Answer: (D)

Remote diagnostics over the Internet requires a device that can bridge the vehicle’s data to a remote technician or cloud service. The AsTech transmitter is designed for this purpose: it plugs into the vehicle’s OBD-II port and transmits diagnostic data over the Internet to a technician’s software or cloud system, allowing live data access, fault code retrieval, and even bi-directional control from a remote location. This is exactly what enables remote diagnostics in a repair context. In contrast, an OnStar module is a built-in telematics system mainly focused on consumer features and in-vehicle services, not the typical tool used by independent techs for remote diagnostics. A Bluetooth dongle only handles short-range connections to a nearby device, not Internet-based remote access, and a USB drive is just storage with no communication capability.
