What are the car fault lights? What are the car fault lights?

The fault indicator is the most important indicator light, such as generator fault indicator, ABS fault indicator, transmission fault indicator, etc. Generally, these fault indicators are rarely lit, or when the engine is started, they will be lit for a moment and then turned off, if the fault indicator is always on, and accompanied by a warning sound, it indicates that the vehicle has broken down or is abnormal. Don't underestimate the fault indicator, if you ignore it, it is very likely to damage the vehicle and seriously endanger driving safety.

If the fault indicator is always on, it needs to be serviced immediately.

Hello 1Oil warning light. Only normal oil pressure can ensure that the oil is delivered to all the friction parts of the engine, too high or too low will affect the normal operation of the engine, and even cause damage to engine parts.

Water temperature indicator. The water temperature indicator mainly indicates the temperature of the coolant in the water tank when the engine is working. Some models that do not have a water temperature gauge will show the coolant temperature in the color of the indicator: blue.

Engine failure lights. The engine fault light is used to show the working status of the engine, and its color is mainly yellow. Twist the key, and the indicator will also light up when the vehicle is performing a self-test.

Brake system fault light. If the brake system fault light is on, first make sure that the handbrake is fully released. If the handbrake is still bright when you release it, check that the brake fluid level is normal or that the brake pads are too thin.

The car fault indicator is mainly displayed on the oil dial, organic oil indicator, brake indicator, ABS system indicator, battery indicator and so on.

There are 5 common fault lights in the car dashboard, and the fault lights are on, not necessarily all of them are "faults"!

1. Tire pressure warning light:Yellow sign, an irregular circle with no seal on top, four small spikes below, and an exclamation point inside. When this sign appears, it means that the tire pressure of the car tire is abnormal, and the tire should be checked in time.

2. Water temperature indicator: This indicator light is generally always on when the car is just started, especially in winter, the blue thermometer-like shape, the water temperature will be lit if the temperature is too high or too low. Some vehicles will have a thermometer in the dashboard, and the pointer will rise or fall with the temperature of the water.

3. Oil pressure indicator:An icon on the dashboard that resembles a "kettle" is the oil pressure indicator, which lights up when the oil pressure is abnormal. When the vehicle starts, the oil pressure indicator will illuminate.

If the oil pressure is normal, it will then be extinguished. If there is an abnormality in the oil pressure, it will always be lit.

4. Warning light of braking system: () on both sides, a circle in the middle, an exclamation point inside, and the entire icon in red. Indicates that there is a problem with the braking system, such as the level of the brake fluid is too low, the handbrake is pulled up, and so on.

5. Battery indicatorIn the process of car driving, the battery is a main function, if there is a problem with this function, then it will cause problems in car driving.

The red indicators are all fault warning lights, so when you see the car indicator turning red, then pull over quickly.

The red warning lights mainly include: oil pressure warning light, engine temperature warning light, charging warning light and brake fluid level warning light.

Without the sense of urgency of the flashing red indicator, many car owners do not pay attention to the flashing of the yellow indicator. However, the appearance of the yellow indicator light means that there is a safety hazard in your vehicle, such as if a light bulb on the car is broken, the "light bulb warning light" will keep flashing to prompt replacement.

Tachometer. The tachometer is generally set up in the dashboard. Placed symmetrically with the speedodometer. The tachometer works according to the magnetic principle, and it receives the pulse signal generated when the primary current in the ignition coil is interrupted.

And convert this signal into a displayable rotational speed value. The faster the engine speed, the more pulses are generated by the ignition coil.

Now cars are generally electronic tachometer, with pointer and liquid crystal digital display, and there is a digital integrated circuit in the meter, which drives the pointer to move or digital display after calculating the voltage pulse delivered by the ignition coil.

Happy New Year's Day to you

Dear, hello, the car fault light appears plus and minus signs, the relevant reasons are as follows, these points?

This phenomenon is caused by the breakage of the generator belt of the first vehicle, which is the need to check the generator belt in time, and if there is a problem, it needs to be replaced in time.

Second, this phenomenon caused by the instability of the power generation of the vehicle generator, this is the need to measure the power generation of the generator, which is normally within the range of grams, if it is not within the range of this range, it is recommended to replace the generator with a new one.

Third, this phenomenon caused by the serious aging of the vehicle battery, it is necessary to detect the service life of the battery under normal circumstances is about 3 to 4 years, if it exceeds this service life, it is recommended to replace the new battery.

Indication: Describe some basic conditions of the vehicle and indicate the current working status of the vehicle. (e.g. light system indicator, water temperature indicator, fuel level indicator).

Prompt: indicates that the current state of the vehicle is abnormal or the operation is incorrect. (e.g. seatbelt lights, door opening lights).

Warning: Indicates that the vehicle is faulty and needs to be repaired. (e.g. engine failure lamp, oil lamp).

Hello is roughly divided into three types: indications, prompts, and warnings.

The car fault lights are: 1. Oil pressure indicator light, this light is the oil alarm light, if the lamp is always on, it means that the stock and pressure of the engine oil are lower than the standard value; 2. When the lamp is on, first check whether the handbrake is completely released, if the light is still on after releasing the handbrake, you need to check whether the brake fluid level is normal, or whether the brake pads are too thin; 3. Steering power warning light, this light is on to indicate that there is a problem with the power steering system; 4. Spike roll engine self-test indicator, this light is used to remind the driver whether the engine is running normally, if it is normal, it will automatically go out, if this light has been on, it means that the engine is faulty; 5. Tire pressure warning light, this light is used to show the condition of tire pressure, if it is normal, this light is off, otherwise it may be insufficient tire pressure or tire damage.

There are a lot of elimination lights for faulty lights, battery indicators.

An indicator that shows the operating status of the battery. It lights up when the power gate is turned on, and turns off when the engine starts. If the ruler is not lit or the elder is not extinguished, the generator and circuit should be checked immediately.

Fuel indicator.

When the light is on, it means that the fuel is about to run out, and generally the vehicle can travel about 50 kilometers from the light to the time the fuel is exhausted.

Cleaning solution indicator.

An indicator that shows the amount of windshield washer fluid. If the cleaning fluid is about to run out, the light will light up, prompting the owner to add the cleaning fluid in time. After adding the cleaning solution, the indicator light turns off.

Electronic throttle indicator.

This light is mostly seen in Volkswagen models, when the vehicle starts self-inspection, the EPC light will be lit for a few seconds, and then extinguished, if there is a fault, this light is on, and it should be repaired in time.

Front and rear fog light indicators.

The indicator light is used to show the working condition of the front and rear fog lights, when the front and rear fog lights are turned on, the two lights are lit, the left side of the figure is the front fog lamp display, and the right side is the rear fog lamp display.

Turn indicators.

When the turn signal is on, the corresponding turn signal flashes at a certain frequency. When pressing the double flashing warning light button under Lingsui Rock, the two lights are lit at the same time, and the indicator light will automatically go off after the turn signal goes out.

High beam indicator.

Shows whether the headlight is in the high beam state, which is usually off.
