OBD is an on-board automatic diagnosis system, which can diagnose the state of vehicles. Read the fault code through the OBD interface of the car, and then analyze and eliminate the fault code of the car. The repairman reads the fault code through the special instrument of the original automobile factory, which can quickly locate the fault problem, facilitate vehicle maintenance and greatly reduce the time of manual diagnosis. The following is the introduction of OBD:

1, OBD real-time monitoring includes: EGR, engine, particulate trap, catalytic converter, oxygen sensor, emission regulation system, fuel system and other systems and components. Such as intake manifold pressure, intake air temperature, air flow rate, throttle position, oxygen sensor voltage, fuel pressure, etc.

2. The original intention of 2.OBD is to monitor whether the automobile exhaust exceeds the standard at any time through the running status of the engine. The general function is to monitor the emission-related components in real time and send the information to the driving computer to judge whether the vehicle is working normally;

3.OBD system will monitor whether the automobile exhaust exceeds the standard at any time from the running condition of the engine. Once the standard is exceeded, a warning will be issued immediately. When the system fails, the fault light or warning light for detecting the engine lights up, at the same time, PCM stores the fault information in the memory, and the fault code can be read from PCM through a certain program. According to the prompt of fault code, maintenance personnel can quickly and accurately determine the nature and local location of fault problems.
