Where is the plug of Beiqi Magic Speed h2 computer?

The plug of Beiqi Magic Speed h2 computer is at the knee position under the steering wheel of the cab. The computer plug is the plug of OBD diagnostic system. OBD is an on-board automatic diagnosis system; This function can diagnose the state of the vehicle. Read the fault code through the OBD interface of the car, and then analyze and clear the fault code of the car. Maintenance personnel can read the fault code through the special instrument of the original automobile factory, quickly locate the fault, facilitate vehicle maintenance and greatly reduce the time of manual diagnosis.

The following is an introduction to OBD:

1.OBD real-time monitoring includes EGR, engine, particulate trap, catalytic converter, oxygen sensor, emission control 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.

The original intention of 2.2. OBD is to monitor whether the automobile exhaust exceeds the standard at any time through the running state of the engine. The basic function is to monitor the emission-related components in real time, and then send the information to the driving computer to judge whether the vehicle works normally;

3.OBD system will monitor whether the automobile exhaust exceeds the standard at any time from the running condition of the engine, and will immediately issue a warning once it exceeds the standard. When the system fails, the failure lamp or engine check warning lamp lights up. At the same time, the powertrain control module (PCM) stores the fault information in the memory, and can read the fault code from PCM through some programs. According to the prompt of fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault. Million car purchase subsidy
