Engine performance depends on the OBD-2 car black box

OBD-2 is the English abbreviation for On-Board Diagnostic Phase 2, the Chinese called "On-board diagnostics' is a device to monitor the vehicle pollution in the car and engine performance computer systems, computer controllable elements in vehicle the problem arises when in the car dashboard warning light illuminates, or check engine warning light to alert the driver of the vehicle repaired immediately, let the car trip computer control components resume normal operation as soon as possible, to avoid vehicle failure, continued to travel the more for a long time, resulting in higher fuel consumption and pollution emissions. Back in 1985, the California Air Resources Board to develop regulations to require that vehicle configuration, after the European Union has also begun to develop laws to force the vehicle to install, while Taiwan EPA in January 1997, the Republic of China began to implement the first 4 emission standard gasoline vehicles with Mitsubishi Coilovers in Taiwan the mandatory requirement for all future cars must be equipped with OBD-2 system, in order to monitor vehicular pollution, unable device models this equipment will not be licensed on the road. Many new cars under the center console are in possession of OBD-2 diagnostic connector, through the assistance of a professional decoding chip, capable of delivering the original computer traffic information displayed on a variety of screens, and the plug also has a write function, can With specialized equipment to conduct internal program Update action, many foreign chip brand is so modified oil modification program When the OBD-2 monitors to an exception occurs, the engine electronic control unit (ECU) will be the fault of information stored in memory, it will be the fault code read from the memory via the OBD-2 test equipment (OBD Scan Tool), Follow the prompts fault codes, maintenance personnel can quickly and accurately determine the nature and location of the fault, let the car repair time is considerably reduced. In addition, the current OBD-2 can monitor real-time driving conditions up to 80 several projects, including vehicle speed, engine Audi Ignition Coils speed, coolant temperature, battery voltage, etc., but also because it can take the initiative to display a variety of information, and therefore the current market many have been able to interpret the emergence of electronic products OBD-2 can be through the head-up display, the LCD screen or mobile phone display various information about the current car.
