Description
OBDII Female Connector:
OBDII female PressFit OBD2 connector on a car Female connector/ connector pinout – front view The OBDII specification provides for 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). SAE J1962 defines the pinout of the connector as:
What Is Universal OBD (Universal OBD Connector ):
In OBDII female PressFit is also improvement over OBD-I in both capability and standardization. The OBD 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 eliminates the need to connect a scan tool to a power source separately.

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 likely, This is also the Bus positive pin of the protocol. |
10 | SAE J1850 Bus- | This protocol uses Variable Pulse Width and is normally used by GM vehicles likely, This is also the Bus negative pin of the protocol. |
4,5 | Ground | It also has the ground of the complete system of the Car including the chassis |
6 | ISO15765-4 CAN High | It also follows a 2-wire CAN protocol at 1Mbps speed. It also has CAN high Pin |
14 | ISO15765-4 CAN Low | It also follows a 2-wire CAN protocol at 1Mbps speed. It also has CAN low Pin |
7 | ISO 9141 – K Line | It also follows asynchronous serial communication protocol, It also has the Kline |
8 | ISO 9141 – L Line | It also follows asynchronous serial communication protocol, It also has the L line |
