Decoding the Konnwei OBD2 Pinout

The OBD2 connector, a standardized 16-pin port, is the gateway to your car’s diagnostic data. Each pin in this connector has a specific function, facilitating communication between the OBD2 scanner and the vehicle’s various control modules. While the pin configuration is standardized, understanding their roles helps troubleshoot connection problems and interpret data more effectively.

Power and Ground: The Foundation of Communication

Pins 4 and 5 are essential for powering the OBD2 scanner. Pin 4 is the chassis ground, providing a return path for electrical current. Pin 5 is the signal ground, ensuring a stable reference point for voltage measurements. Pin 16 provides battery power to the scanner, enabling it to operate independently of the vehicle’s ignition.

Communication Lines: The Language of Diagnostics

Pins 2, 6, 7, 10, 14, and 15 are dedicated to communication. Pin 2 is the J1850 Bus+ line used in some Chrysler, Ford, and GM vehicles. Pin 6 is the CAN High (J-2284) line found in most modern vehicles. Pin 7 is the K-Line (ISO 9141-2) used in many European and Asian vehicles. Pin 10 is the J1850 Bus- line. Pin 14 is the CAN Low (J-2284) line, completing the CAN bus circuit. Pin 15 is the L-Line (ISO 9141-2) for bidirectional communication.
