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

Automotive wire harness crimping definition: A connection method for wires and terminals during the assembly of wires during crimping.By applying a certain mechanical external force (referring to stripping the insulation of the wire and pressing the terminal to engage the conductor), two types The materials are tightly bonded to achieve the purpose of electrical conduction or firm bonding. Therefore, precision crimping tools can ensure good crimping quality. Current crimping tools include manual tools, semi-automatic crimping equipment, and fully automatic crimping equipment. Three. Function: Good crimping terminal can reduce resistance, reduce copper wire oxidation at crimping place and have various excellent properties such as firm tightness and good electrical conductivity, firm tightness explanation: within a certain range after tensile test Not to be pulled loose or disconnected. Notes on crimping: a. Whether there is any problem in the installation and debugging of the equ...

What is the IPC620 Standard

-
图片
The IPC standard is the most important standard document for electronic engineering personnel. It has very authoritative and enforceable regulations on the reliability, safety, standardization, and manufacturability of electronic equipment and systems. ​ This standard is an appearance acceptance standard related to cable assembly established by the Cable Assembly Association and the Electronic Connection Products Committee. If no standards for process inspection and finished product inspection are defined, IPC 620 can be used as the inspection standard document for the product alone. It establishes process control or defective products that allow repair/rework. This information suggests that it needs to be improved through statistical process control plans. IPC 620 mainly includes the following: conductor/cable preparation, measurement of cable assemblies and conductors, crimp terminals, insulation piercing connections, solder terminals, connector connections, compression/inject...

What is the Difference Between J1939 Connector Type 1 and 2?

-
图片
  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...
