OBD-II pin Definition

-

 In order to better ensure the safety of vehicles and protect the environment. After 1996, automakers began to equip cars and trucks with OBD-II ports. Each system is basically the same, but there will be subtle changes. These are called agreements and are specific to the vehicle manufacturer.

OBD-II pin Definition​

The diagnostic trouble code is stored in the computer system. There are many manufacturers in the world, and the codes may be different. However, anyone with an OBD-II scanning tool can connect to the port and read the diagnostic trouble code from the computer. The reason why the OBD-II scanning tool reads the code is due to the standardized pin arrangement. The standardized pin assignments are as follows.

OBD-II pin Definition

Pin 1: Used by the manufacturer

Pin 2: by SAE J1850 PWM and VPW

Pin 3: For manufacturer use only

Pin 4: Ground

Pin 5: Ground

Pin 6: CAN be used by ISO 15765-4 CAN

Pin 7: K-ISO 9141-2 and ISO 14230-4 lines

Pin 10: Only by SAE J1850 PWM

Pin 14: by ISO 15765-4 CAN

Pin 15: ISO 9141-2 and ISO 14230-4

Pin 16: Car battery power supply

  SAE J1939 (hereinafter referred to as J1939) is the recommended standard of the American Society of Automotive Engineers (SAE). It is controlled and communicated by the "Truck and Bus Electrical & Electronics Committee" (Track & Bus Electrical & Electronics Committee). Developed and written by the Track & Bus Control and Communications Network Subcommittee. J1939 has become a recognized industry standard and choice for commercial vehicle diagnostics and data communication heavy, off-highway, truck, bus, ship propulsion, power generation, industrial pumping, construction, and material handling machinery. J1939 is a high-level protocol network (CAN) based on Controller Area. It is widely used by the diesel engine industry to provide diagnostic data such as vehicle engine speed, temperature, oil temperature, exhaust emissions, and other customizable options. J1939 connectors are divided into black and green rubber cores, but do you know the difference between t...

What is overmolding? In short, overmolding is an injection molding process in which two or more materials are used to combine a harness wire and a connector to form a single part, and the cable assembly is placed in a mold. In this process, the first material substrate will be covered by other materials. The overmolding process requires the use of insert molding (single injection) or multiple injection molding techniques to cover rigid plastic parts with TPU layers or other overmolding materials. So what are the benefits of the connector and harness overmolding process? Benefits of overmolding connectors and harnesses: 1. Increase the flexibility of the cable harness exit so that most of the movement between the cable harness and the connector occurs at the cable harness exit. 2. Provide abrasion resistance, impact resistance or impact resistance. 3. Fix the cable assembly by sealing the assembly in plastic. 4. Provide 360 degree strain relief and increase tension. 5. Cr...

In the context of global environmental conservation, new energy vehicles have become an inevitable trend in the development of automobiles worldwide. PwC's first blueprint for the Chinese auto industry, released on December 8, states that China's new energy vehicle sales are far ahead of other markets in the world. With the government's vigorous support for new energy vehicles, China's new energy vehicle era has arrived. Global sales of new energy vehicles reached 500,000 in 2015, of which 330,000 were sold in China, three times the previous year, and far ahead of other markets in the world. Accelerating development, Internet giants and other emerging players are actively entering the market, bringing pressure and shock to traditional car manufacturers and dealers. There is no doubt that new energy and intelligent connected cars have become the mainstream of the automotive industry, and the demand for applicable wiring harnesses will also increase significantly.
