Where is the link 02obd interface?

The 02obd interface of Pacific Auto Network is under the steering wheel and above the driver's left foot. The size, length, width and height of Lake 02 are 4448 mm/1890 mm/1528 mm respectively, and the wheelbase is 2702 mm ..

Sign 408OBD interface is under the steering wheel, and there is a cover plate at the knee position of the left leg. After prying open the cover, you can see the OBD interface, which is the interface for the automobile testing instrument to access the ECU of the automobile computer.

The role of obd interface The obd interface of an automobile is similar to the interface of a plug-in board on an automobile, and is mainly used for understanding automobile information. It can be connected to the OBD interface through a computer, so that it can know what the car fault code says is wrong with the car, and then it can be repaired accordingly. It provides great convenience for automobile maintenance and the development of automobile and other related functions.

What is OBD? OBD is actually an extended monitoring system for automobile fault diagnosis, which can be called on-board automatic diagnosis system. It can monitor the working state of the vehicle function module in real time during the driving process of the vehicle. If abnormal problems are found, specific faults will be detected and judged according to specific algorithms. For example, monitor the running state of the engine and the working state of exhaust aftertreatment, and once it is found that it may cause excessive emissions, it will immediately issue a warning.

The working principle of OBD is that the OBD is connected to the electronic control unit (ECU) through various component information related to emissions, and the ECU has the function of detecting and analyzing emission-related faults. If there is a fault, ecu will record the fault information and related codes, and send out corresponding prompts to inform the driver through the fault light, and then ecu will ensure the access and processing of the fault information through the standard data interface.
