How to analyze non-tariff measures

Warning Light Engine Malfunction Detected: Engine fault light exclamation mark owners all want their cars to be How to analyze non-tariff measuresin good condition while driving, but sometimes engine failures occur at the most unexpected time. At this time, a white snow or red exclamation mark will light up on the dashboard, which is exactly the engine fault light we are familiar with. Such a signal is of great significance to the owner, because it indicates that there is a problem with the engine and needs to be dealt with in time. This article will introduce the knowledge points related to this problem.First, under what circumstances will the fault signal light appear? The appearance of vehicle fault signal lights is usually detected by one or more fault codes by the in-vehicle monitoring system. The system will start the warning light immediately after detecting the problem, reminding the car owner that measures must be taken to correct the problem. At this time, if you fail to take action and put the car into stable mode, the vehicle may be forced to stop or cause serious damage. In fact, there are various types of fault signal lights, and car owners need to pay attention to the maintenance at the 4S store or repair shop as soon as the warning light is on. Second, what causes the fault signal light to light up? The lighting of the engine fault light is usually caused by the failure of the engine-related parts. The most common problems of these parts are electronic control units, oxygen sensors, ignition systems, fuel pumps, cooling systems, etc.If the owner does not deal with these problems in time, the engine problem may gradually worsen, and the maintenance cost will be high, reducing the efficiency and value of the vehicle. The common causes of fault signal lights are as follows: 1. Damage to the fuel system, including fuel pumps, brake systems, oxygen sensors, cargo distributors and plots, need to be loosened and recapitalized for maintenance. Two. Exhaust system, including intake system, air flowmeter, intake cooler and catalytic converter. Describe the general problem of the exhaust system that it has not been properly repaired, causing corrosion, etc. 3. The fault code appears in the transmission controller or vehicle control unit. These are very serious problems, especially leakage and damage to the anti-lock brake. Vehicles in this case need to see professional maintenance personnel immediately.Third, what is the stable mode? Stable mode refers to a temporary working method in which the electronic control unit is activated to protect the engine when the vehicle fails. The main job of the stable mode is to reduce the operating range of the vehicle in the event of an engine failure to avoid more serious damage. If the owner continues to drive, it will greatly increase the cost of failure and maintenance, which will further capitalize the vehicle or cannot be repaired at all. When the engine fault light is on, there are several situations that may cause the vehicle to enter the stable mode, including: 1. The engine electronic control unit fails; 2. The engine sensor system fails; 3. The engine valve system is faulty; 4. The engine ignition system failed. If the owner realizes that his vehicle is entering stable mode, he should immediately drive the car to a safe parking spot for maintenance.In a word, when the engine fault light turns on, the owner should pay attention to it at any time. The correct way to deal with it is to pay close attention to the timing and situation of the fault signal light, and then send the vehicle to a professional repair station for repair. For cars of different brands and parameters, the handling points of fault signals and stability modes will also be different. The shorter the maintenance time of the vehicle, the more it can reduce the cost and increase the safety and efficiency of the vehicle.
