J1939 connectors are divided into black and green rubber cores, but do you know the difference between t...

  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. ​ 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. 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...

  With the rapid development of the times, cars have entered everyone's field of vision. The safety of vehicles has also received more attention. When the car breaks down, the corresponding solution will be found. The OBD scanner and OBD wiring harness can be easily purchased online. After understanding the OBD wiring harness, you may not know whether your car is OBD1 or OBD2. Let me show you how to judge OBD1 and OBD2. It depends on your country or the market where the car is manufactured. Let us take the example of a car in the US market. If your vehicle was manufactured or sold in the United States in 1996, it is most likely a vehicle that meets the OBD2 standard. To determine whether your car is OBD1 or OBD2, find the year of manufacture on the white card at the driver’s side door and check the following: United States-1996            New Zealand-2006 Canada-1998              Argentina-2009 Japan-2002   ...

  OBD is the abbreviation of On-Board Diagnostics in English. This system is mainly to monitor the operating conditions of the car's engine, and a warning will be issued when the exhaust gas exceeds the limit during operation. When the system fails, the fault (ML) light or the Check Engine (Check Engine) warning light is on, and the powertrain control module (PCM) stores the fault information in the memory, and the fault code can be read from the PCM through a certain program. The maintenance personnel can quickly and accurately determine the nature and location of the fault according to the prompt of the fault code. ​ OBD1 is applied to cars manufactured in California to control vehicle emissions in the state, detect engine problems, and report fault codes. However, OBD1 is a standard in California. Many General Motors have problems, but they cannot be tested. OBD-1 is not standardized among manufacturers. OBD2 became a national standard in the United States in 1996, and fault cod...

  With the rise of the electronics industry, more and more products are used in terminal blocks and their applications are becoming more extensive. In fact, the terminal is a kind of accessory product used to realize the electrical connection, which is divided into the category of the connector in the industry. Many people are not very familiar with the types of terminals. Generally, there are six types of terminals: ​ 1. Plug-in It is formed by two parts plugging and unplugging. One part presses the wire tightly and then plugs it into the other part, which is soldered to the PCB board. The mechanical principle of the connection bottom and the anti-vibration design ensure the long-term airtight connection of the product and the reliability of the finished product. Mounting ears can be added to both ends of the socket. The mounting ears can protect the splices to a large extent and avoid the lack of proper placement of the splices. At the same time, this socket design can ensure tha...

  Before OBD-I, each manufacturer had their own set of standards for OBD, meaning that mechanics had to buy expensive scan tools for each manufacturer. OBD-I was first introduced in 1987, and started the standardization of onboard diagnostics. It had sensors that detected emissions and was able to minimize them through emissions-controlling valves. However, it had many problems and shortfalls. ​ As a result, in 1996 car manufacturers started to equip cars and trucks with an OBD-II port. Every system is mostly the same, but there are slight variations. These are known as protocols, and are specific to vehicle manufacturers. There are five basic signal protocols: SAE J1850 PWM: Pulse Width Modulation, used in Ford vehicles SAE J1850 VPW: Variable Pulse Width used in General Motors vehicles ISO9141-2: Used in all Chrysler and a variety of European or Asian vehicles ISO14230-4 (KWP2000): Keyword Protocol, used in a variety of European and Asian imports as well as Honda, Jeep, Land Rove...

  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 OBD-II scanners can connect to these ports and identify the trouble code from any manufacturer that uses one of the OBD-II protocols.

1. The terminal is not assembled in the rubber core and the needle is pulled out The terminal is not assembled in place in the rubber core. Intuitively speaking, it is the employee's operation error, which caused the outflow of non-conforming products. In the current wire harness manufacturing industry, terminal assembly basically relies on manual operations. The commonly recognized terminal insertion method in the wire harness industry is "one plug, two listen, three pull". The most important thing is "three-return pull". The effectiveness of the pull-back action determines the first pass rate of the withdrawal terminal. The staff's operational proficiency determines the effectiveness of the pullback action. Therefore, employees need to self-check during assembly work. The same IPQC also needs to conduct random inspections. 2. When the rubber core and the rubber core are inserted, the terminal is ejected or forced to exit When the rubber core and t...

How to avoid the pin withdrawal of the connector terminal is a key concern of the wire harness practitioners. Wire harnesses are used as a bridge connecting the various electrical components of the vehicle to realize the normal connection of various electrical circuits, and more and more content needs to be controlled. There is a saying in the industry that electrical appliances are the most problematic in each segment of the car, and the most problematic component in the electrical appliance is the wiring harness. In view of the many failure modes of automotive wiring harness products, the withdrawal of connector terminals is the most unacceptable. As there are many factors affecting needle withdrawal, it covers all aspects of design, parts production, and wiring harness manufacturing. ​ When analyzing the needle withdrawal problem, the harness withdrawal problem is shown in the figure below. There are two reasons for the needle withdrawal problem found from the user's perspe...

When encountering wiring harness problems, we must first understand what a wiring harness is. After understanding, we can discover the problem, find the problem, and solve the problem. A wire harness is a bunch of wires or cables that use low-cost components to organize their components together. Wire harnesses usually use thermoplastic sheathing materials to provide some protection for the wires and cables inside, but in most cases, these components already have their own protective covers, which minimizes the need for other protective measures. demand. The wiring harness solves two basic problems in the electrical system (geometric restrictions and electrical requirements). Wire harnesses help provide a physical support system for cables and wires to be used in very specific spaces in an organized and protected manner. Wire harnesses are used in a wide range of applications, from aircraft engines to commercial and residential wires. Wire harnesses provide a low-cost solution for...

Cable assemblies and wiring harnesses are often confused. This confusion is understandable because many professionals can use these terms with each other, and the products themselves have very similar basic functions. However, these products and their uses are different, and the products themselves need to be redefined to accurately obtain the desired products. Yeahui will briefly explain the difference between cables and wiring harnesses, as well as the usage of each product worldwide. ​ Before discussing the differences between cable assemblies and wiring harnesses, you need to understand the differences between wires and cables. Although these terms are completely different, they can be used with each other. Essentially, a wire is a bunch of conductive materials, such as brigade or copper. A cable is two or more wires that extend together. They are usually glued or woven together, which is why the cables you see look like a bunch of tangled wires. Fundamentally, a wire harnes...

In many industrial productions, the use of wire is indispensable. It is also called a cable. In terms of appearance, its length and diameter can be customized. The most common specification is a material with a diameter of 5mm-15mm. From the point of use, it is necessary to choose according to the situation of use. ​ Regarding the wire classification: divided into electronic wires, wires, terminal wires, PU wires, electronic wires, wires, electronic connecting wires, connecting wires, and flat wires. The current common molding wire materials are generally PVC and TPE. Both types of wire have their own advantages. The wire harness made of TPE feels smooth and does not stick to your hands, and can achieve a matte or delicate data line surface; the raw materials are safe and non-toxic, will not cause irritation to human skin, and do not contain toxic plasticizers. This type of material is suitable for wire harnesses that are in close contact with the human body. The wire harness ma...

The jacket refers to a connector that is injection-molded and press-molded from engineering plastics, PVC materials, or metal materials, thereby protecting the connection points and the role of connecting various electrical appliances. Support the protection terminal to make it firmly contact, accurately position, dustproof, antifouling, moistureproof, insulation protection, etc. Commonly used sheath materials are mainly PA6, PA66, ABS, PBT, PP, PVC, etc. When designing the plug-in, you can choose different materials according to different needs, and add flame retardant or reinforcing materials to the plastic according to the actual situation, in order to achieve the purpose of strengthening or flame retardant, such as adding glass fiber reinforcement. The materials and properties of commonly used terminals are as follows: brass (copper-zinc alloy) has the characteristics of low cost, good elasticity, and good forming quality, but it is easy to crack under stress and corrosion, an...

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...

The selection of wire should be considered from the aspects of circuit conditions, ambient temperature, and mechanical strength. First. Circuit conditions: 1. Allowable current: Allowable current refers to the current value at normal temperature. The allowable current of the wire should be greater than the maximum current of the circuit. 2. The voltage drop of wire resistance: When the wire is long, use a wire with a large diameter to reduce the influence of resistance on the voltage. 3. Rated voltage and insulation: In use, the maximum voltage of the circuit should be lower than the rated voltage of the wire. 4. Signal shielding: When the signal level is small, it is susceptible to interference from noise signals. Shielded wires are often used to overcome the interference. Second. Environmental conditions: 1. Temperature: Temperature will make the insulation layer of the wire soft and hard and cause a short circuit. 2. Electrochemical resistance: Under normal circ...

Nylon tube is widely used by many automobile manufacturers in the world because of its advantages such as easy assembly, cleanness, anti-aging, and corrosion resistance. ​ For a car to achieve safe driving, it must have good braking performance, so the parts of the brake system are also called "security parts". Due to the very high requirements for nylon tubes used in automotive braking systems, it must be rigorously tested and researched before they can be used in automobiles. There are also strict requirements for the installation of nylon tubes in automobile brake systems: they must have good sealing performance and should be easy to disassemble, adapt to various weather and environments, and have good anti-vibration effects. When designing the joints of nylon pipes, the following two principles must be met: (1) Under the specified conditions, the pipe joints must have good sealing, and the pipe joints must meet the strength when the pipe fittings are pulled out; (2...
