Product Description

We can make it by soldering type with short or long pin for soldering to wires or PCBA. Also assembling type placed with PCBA inside, and sealed the plastic body by ultra sound machine. For the femlale OBD2 connector by assembling type, we have retainer designed to strengthen the crimped terminal to avoid half insertion or terminal dropped problem.  Our OBD connectors are ODM products, the terminal, plastic connector all processed by ourselves..

Product Details


01 The OBD connector is an area within your car engine system which allows for the connection and reading of the eventual data by the OBD scan tool user. In the old car versions, it was placed somewhere on the car dashboard.

All cars and light trucks built and sold were required to be OBD II connector in the United States after January 1, 1996. In general, this means all 1996 model year cars and light trucks are compliant, even if built in late 1995.
Two factors will show if your vehicle is definitely OBD II equipped:
1) There will be an OBD II connector as shown below,
2) There will be a note on a sticker or nameplate under the hood: "OBD II compliant".


The OBD connector is officially called an SAE J1962 Diagnostic Connector, but is also known by DLC, OBD Port, or OBD connector. It has positions for 16 pins. OBD stands for On-Board Diagnostic. It’s the standardized system that allows external electronics to interface with a car’s computer system. It has become more important as cars have become increasingly computerized.


Several automakers introduced computer interfaces for their own cars before the 1990s, but the push to standardize didn’t begin until 1991, when the California Air Resources Board (CARB) mandated that all cars sold in California needed some form of OBD capability.  However, CARB didn’t issue standards for the systems until 1994. Known as OBD II, that standard was implemented for the 1996 model year.



02   OBD II cars have a port — usually located under the dashboard on the driver’s side — that devices can plug into and connect to a car’s computer.
As the name implies, diagnostics are the primary purpose of OBD. When a car’s sensors decide that something is amiss, they trigger a message known as a “trouble code,” which may manifest as a “check engine” light or other warning on the dashboard. OBD scanners can check these trouble codes to determine exactly what’s wrong, and clear them from the computer’s memory once the problem is fixed. Diagnostics may be the most important function of OBD equipment, but these tools can also be used to make your car go faster. That is why OBD connector become more and more popular in automative industry, and it also become an very indispensable part for the automobile.


03  OBD-II is an on-board computer that monitors emissions, mileage, speed, and other data about your car. It’s connected to the Check Engine light, which illuminates when the computer detects a problem. The OBD-II on-board computer features a 16-pin port located under the driver’s side dash. It allows a mechanic or anyone else to read the error code using a special scan tool.


Diagnostic Trouble Codes (DTC) are stored in the computer system. Codes can vary from one manufacturer to another. However, anyone with an OBD-II scan tool can connect to the port and read the diagnostic trouble codes from the computer.


The reason any OBD-II scan tool can read the codes is because of the standardized pinout. Scan tools can read from any of the protocols listed above. The standardized pinout is as follows.

    Pin 1: Used by manufacturer
    Pin 2: Used by SAE J1850 PWM and VPW
    Pin 3: Used by manufacturer
    Pin 4: Ground
    Pin 5: Ground
    Pin 6: Used by ISO 15765-4 CAN
    Pin 7: The K-Line of ISO 9141-2 and ISO 14230-4
    Pin 10: Used only by SAE J1850 PWM
    Pin 14: Used by ISO 15765-4 CAN
    Pin 15: The K-Line of ISO 9141-2 and ISO 14230-4
    Pin 16: Power from the car battery



Product Applications

Today, SAE J1939 is used throughout for heavy-duty commercial vehicles such as trucks, busses and construction equipment. For agricultural machinery ISOBUS is mandatory which is based on J1939, and based on the OBD2 Controller Area Network, CAN, protocol used in all new vehicles.
A few of the myriad uses are:

     J1939 Heavy-Duty-Truck-Data-Convert
     J1939 CAN BUS diagnostic unit (for trucks)
    J1939 body builder CAN bus monitor (for trucks)
    J1939 interface industrial engine display unit
    ISOBUS-control devices
    CAN bus Universal Controller
    CAN gateway and bus simulator
