    The car dashboard is a device that reflects the working conditions of each system of the vehicle. Common ones are fuel indicators, cleaning fluid indicators, electronic throttle indicators, front and rear fog light indicators and alarm lights. The fault on the dashboard of the car can not only monitor the condition of the vehicle in real time, but also the most direct manifestation of the driving state of the car.

    The most complete collection of car fault lights in history, I hope it will be helpful to all car owners. Really recommend collecting it!

    Generally, there are 4 colors of car indicators: red, yellow, green and blue; Different colors have different meanings. Do you know?

    Red indicator (hazard).

    The red indicators are all fault warning lights, so if you see the car indicator light turning red, you need to stop driving immediately, and immediately clear the fault and repair it immediately. The red warning lights mainly include: oil pressure warning light, engine temperature warning light, charging warning light and brake fluid level warning light.

    Yellow indicator light (early warning, precaution).

    The appearance of the yellow indicator light means that there is a safety hazard in your vehicle, such as a broken light bulb on the car, the "bulb warning light" will continue to flash to prompt replacement, as well as engine (exhaust system) fault lights, oil system fault lights, battery and power generation system fault lights, etc. When the yellow indicator light is on, the owner should pay attention and deal with the repair at the appropriate time.

    Green indicator light (safe driving).

    The green indicator is the function indicator of the vehicle, which is generally the status indication of the vehicle's function, indicating that the function is on or off, for example, the turn signal flashing when turning is green.

    Blue indicator light (reminder, need to pay attention).

    Like the green indicator, the blue indicator of the high beam indicator and the internal circulation indicator can generally also play a role in prompting the working status of each function of the vehicle. For example, if the high beams are blue when they are turned on, you need to pay attention to whether the high beams affect other vehicles.

    The picture below is a partial general-purpose fault light**:

    Generally, there are the following reasons: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

    The specific situation is analyzed as follows; 1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

    Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and if it is serious, it will cause the engine failure light to turn on. The extender can also cause the engine failure light to come on.

    1. Oil alarm light, the shape of this fault lamp seems to be a teapot, if the fault light is lit on the dashboard, then it means that the oil in the engine is insufficient, and it needs to be replenished in time, if you continue to drive forward, then the wear of the engine will be greatly increased, because the lubrication effect will not be very good in the case of insufficient oil volume. Severe cases may result in engine damage.

    2. Engine fault light, under normal circumstances, this light is yellow, once it is lit, it proves that the engine may be faulty but the vehicle can still drive. It is advisable to check the engine for troubleshooting as much as possible. However, in the process of daily use of the car, as long as the maintenance is in place, the engine is not short of oil, coolant, and there is no gasoline of the wrong label.

    In this case, if you turn on this light, most of them are false positives from the system. The reason for the false alarm of the system may be that the whole car is powered off and the battery is replaced, or the battery voltage is too low.

    3. Brake system fault lamp. The brake system fault light is shaped by an exclamation mark and a letter P wrapped in a circle. If this fault light is on, it means that there is a problem with the car's braking system.

    Please get out of the car for an inspection and repair it promptly. Because the brake system of the car plays a vital role in the safety of the people in the car, if there is a problem, the people in the car will be in danger.

    4. Tire pressure warning light, when the tire pressure warning light is on, it means that the tire pressure is abnormal, which may be low or high. One of the greater safety hazards is the vehicle puncture, if the vehicle has a puncture when driving, the consequences are unimaginable.

    5. Water temperature warning light, when the water temperature warning light is on, it means that the engine temperature is too high. The essence of the engine is that the heat dissipation effect of the engine is not good, and it is necessary to stop and check the vehicle for failure, and if you continue to drive, it may cause damage to the engine.

    6. Battery warning light, if this fault light is on, it means that the battery of the vehicle is faulty, which affects the use of electrical equipment on the vehicle. So when you see the battery alarm light on, you should go to the repair shop in time to deal with it.
