What is the use of terminal 16 on the OBD-II data link connector?

• A. Chassis ground
• B. Signal ground
• C. 12 V positive
• D. Manufacturer's discretion

Answer: (C)

Terminal 16 on the OBD-II data link connector is designated for 12 V positive. This terminal is important because it provides power to devices that may need to be powered while connected to the OBD-II system, such as scan tools or diagnostic equipment. By supplying a constant 12 V, the system ensures that these devices can operate without needing a separate power source, making diagnostics and vehicle data retrieval efficient and effective. Understanding the function of this terminal is essential for anyone working with OBD-II systems, as it allows technicians to effectively diagnose issues and communicate with the vehicle's electronic control units (ECUs). This clarity in terminal function supports the overall performance and reliability of automotive diagnostics.
