Identify duty-free items via HS code

ECM engine control module: How to use it correctly?Identify duty-free items via HS code The ECM engine control module is an indispensable part of modern cars. It is a microprocessor installed in the vehicle, which can detect the operating status of various parts of the vehicle through sensors and control the operation of the engine according to these data. This article will introduce the basic principle of the ECM engine control module and the precautions for the correct use of the module. 1. Basic principle of ECM engine control module EThe basis of the work of the CM engine control module is the sensors that detect various parts of the vehicle, such as engine speed sensors, oxygen sensors, throttle position sensors, etc. When the sensor collects the relevant data of the vehicle, ECM will determine the current operating status of the vehicle according to these data and make corresponding adjustments. So, what data can the ECM engine control module control the vehicle by detecting? First of all, it can monitor the vehicle speed through the vehicle's speed sensor to ensure that the engine fuel supply matches the vehicle speed. Secondly, it will use the engine temperature sensor to monitor the temperature of the engine to ensure that all engine parts are running within the appropriate temperature range. In addition, ECM can also detect oxygen sensors to determine whether the fuel-to-fuel ratio of the engine is correct.The ECM engine control module will analyze and process these data through computer programs, and then make appropriate adjustments to the operation of the engine to ensure the normal operation of the engine. 2. Precautions for the correct use of the ECM engine control module When using the ECM engine control module, you need to pay attention to the following points: (1) Maintain the ECM in the normal working state. The ECM engine control module needs to be maintained in a normal working state. If the circuit board or sensor is damaged or interfered with, the ECM engine control module may not be able to detect vehicle data or make correct adjustments, thus affecting the performance and driving experience of the engine. ( 2) Pay attention to the correct operation of the ECM engine control module. You also need to pay attention to the throttle position. One is not rightThe exact throttle position sensor may cause the ECM engine control module to fail to recognize the acceleration or deceleration of the vehicle, resulting in the wrong fuel supply when the engine starts, resulting in difficulty in starting or failure of the car. ( 3) Try to avoid vibration and impact. The ECM engine control module should try to avoid vibration or collision. Because the complex circuit boards and sensors of the ECM engine control module may be damaged by vibration or impact. In addition, when disassembling or installing the ECM engine control module, be sure to follow the manufacturer's instructions to avoid damaging it. ( 4) Always pay attention to the vehicle fault light. When the ECM engine control module recognizes that there is an abnormality in the vehicle data, it will automatically turn on the vehicle fault light to remind the driver to pay attention. At this time, according to the fault as soon as possibleThe code table inspects and repairs the vehicle, and the fault code should not be cleared to avoid more hidden faults. 3. Summarize that the ECM engine control module is an indispensable part of modern vehicles. It is as important as the engine, gearbox and other components. To make the ECM engine control module work normally, it is necessary to maintain its normal state and take some basic measures, such as reasonable maintenance of sensors, avoid vibrations and impacts, always pay attention to vehicle fault lights, etc., to ensure its correct operation, reliably control the vehicle, and ensure the driving experience and safety.
