OBD-II Female ECU Pressfit Connector :
Female OBD-II connector on a car Female OBDII Male Connector 16 PIN pinout – front view The OBD-II 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 Male Connector 16 PIN 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 an OBD2 Connector?
OBD stands for Onboard Built-in Diagnosis. As the name suggests it is a diagnosis system that is built into all modern cars (after 1996) which has a computer based application that monitors the performance of your car through your speed, mileage, fuel emission data etc.. Apart from this it also measures some of the important vital parameters of an Engine. This complete system is called as an ECU (Engine Control Unit).
OBD-II Female ECU Pressfit 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|
