Description
OBDII Female Connector:
Female OBD2 connector,obd connector, diagnostic connector,16 pins obd2 connector on a car Female connector pinout – front view The OBDII specification also has a standardized hardware interface—the female 16-pin (2×8) J1962 connector. Unlike the OBD-I connector, which was sometimes found under the hood of the vehicle, the OBD-II connector is required to be within 2 feet (0.61 m) of the steering wheel (unless an exemption is applied for by the manufacturer, in which case it is still somewhere within reach of the driver).
What Is Universal OBD (Universal OBD Connector ):
OBDII is an improvement over OBD-I in both capability and standardization. The OBDII Female Connector standard specifies the type of diagnostic connector and its pinout, the electrical signaling protocols available, and the messaging format. It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each. There is a pin in the connector that provides power for the scan tool from the vehicle battery, which also eliminates the need to connect a scan tool to a power source separately.
OBD2 Connector Pinout Configuration
| Pin Number | Pin Name | Description |
| 1,3,8,9,11,12,13 | Blank | These pins are not standard and are vendor-specific. It is also not required for normal communication/interfacing |
| 2 | SAE J1850 Bus+ | This protocol uses Variable Pulse Width and is normally used by GM vehicles. Moreover, this is the Bus positive pin of the protocol. |
| 10 | SAE J1850 Bus- | This protocol uses Variable Pulse Width and is normally used by GM vehicles Moreover, this is the Bus negative pin of the protocol. |
| 4,5 | Ground | The ground of the complete system of the Car is also including the chassis |
| 6 | ISO15765-4 CAN High | It follows a 2-wire CAN protocol at 1Mbps speed. It also has CAN high Pin |
| 14 | ISO15765-4 CAN Low | It follows a 2-wire CAN protocol at 1Mbps speed. It also has a low Pin |
| 7 | ISO 9141 – K Line | It follows asynchronous serial communication protocol, It also has the Kline |
| 8 | ISO 9141 – L Line | It follows asynchronous serial communication protocol, It also has the L line |
