What does it mean when the car does not meet the starting conditions?

ECO is a green driving mode signifier that comes in two forms: passive and active.

The passive form is only an indicator light on the instrument, it will not interfere with the driver's driving behavior, but when the vehicle exceeds 20km h speed, the driver's driving behavior is estimated whether it is in line with green driving, if it is in a more economical driving operation, the ECO indicator light will be lit, on the contrary, if the more aggressive and fuel-efficient driving behavior indicator will not be displayed, its role is only as a prompt, and will not affect the state performance of the vehicle.

The active ECO mode has a switch, after the driver triggers the switch, even if the accelerator is pressed deeply and aggressively, the vehicle still maintains a very gentle acceleration state, and it is difficult for the vehicle to reach the higher speed of the engine, and the speed is very slow even if the accelerator pedal is pressed to the end after exceeding the economic speed.

The instrument display ECO refers to the driving mode of the vehicle, this mode is the economic mode of the vehicle, turn on this switch, the vehicle is in the economic mode of driving, the vehicle computer controls the amount of fuel injection, and the transmission control module controls the shift logic, so that the vehicle is in the most economical mode of driving.

Active Eco driving mode is usually equipped with a button, which can be turned on by the owner, and a series of settings related to driving will be changed, such as a smaller throttle opening corresponding to the same accelerator pedal depth (the throttle becomes less sensitive), the transmission shift logic is more economical (upshifting earlier), and some vehicles will also adjust the output power of the air conditioner at the same time. The ECO mode settings will vary from manufacturer to manufacturer, but the principle is basically the same, which is to change the computer program to affect the driving characteristics of the vehicle. It is commonly found on Japanese and Korean cars, such as:

Dongfeng Nissan New Teana, Dongfeng Honda Civic, Beijing Hyundai Langdong, etc.

The main principle of active ECO mode is not very complicated, mainly in the process of vehicle driving, the automatic transmission gear, engine speed, vehicle speed, braking and transmission oil temperature and other conditions that have an impact on fuel consumption are comprehensively judged and analyzed, and the ECU control unit calculates the optimal fuel amount to provide the engine to do work, so that the fuel consumption is effectively reduced compared with the ordinary driving mode. To put it simply, it is to control the engine speed in a reasonable gear to reduce unnecessary fuel consumption.

ECO is a symbol of a green driving mode, which is divided into two forms: passive and active.

The passive form is only an indicator light on the instrument, it will not interfere with the driver's driving behavior, but when the vehicle exceeds 20km h speed, the driver's driving behavior is estimated whether it is in line with green driving, if it is in a more economical driving operation, the ECO indicator light will be lit, on the contrary, if the more aggressive and fuel-efficient driving behavior indicator will not be displayed, its role is only as a prompt, and will not affect the state performance of the vehicle.

The active ECO mode has a switch, after the driver triggers the switch, even if the accelerator is pressed deeply and aggressively, the vehicle still maintains a very gentle acceleration state, and it is difficult for the vehicle to reach the higher speed of the engine, and the speed is very slow even if the accelerator pedal is pressed to the end after exceeding the economic speed. In other words, after starting the ECO, the trip computer will reduce the sensitivity to human operation response, and control the acceleration and driving state of the vehicle more according to the fuel-saving mode.

Now we pay attention to environmental protection, energy saving, and green travel, and ECO, simply put, is an energy-saving economic model, and most vehicles will be equipped with active ECO functions as standardOf course, there is also a passive ECO, the difference between the two is that the active ECO has a button on the car, and the owner can choose to turn it on or off, while the passive ECO has no buttons, and it is completely based on the driving computer to judge whether it takes effect.

The principle is very simple, once the ECO mode is turned on during the driving process, the driving computer will intervene in the vehicle, and then obtain the most suitable amount of fuel for the engine to do work through the extraction and calculation of vehicle speed, speed, gearbox and other data, and finally achieve fuel saving.

To take the simplest example, when the vehicle turns on the ECO mode, the most intuitive feeling is that when you kick the accelerator, it should go straight to 80km h according to the usual speed, but at this time, you don't, but you will feel that the accelerator does not obey.

The ECO mode sounds like an eco mode, but it actually sacrifices power to save fuel. The driving computer integrates various data of drivingIn this way, the work of the engine is limited, and the output power of the engine is directly reduced.

What role can it play in the process of driving? Whether it can save fuel.

The biggest effect of eco mode is to reduce fuel consumption, which can save about 6% of fuel consumption, in fact, the overall fuel saving is not obvious, because eco mode will also be limited by various conditions.

For example, when driving on a high speed, when the speed reaches 90 km h, 100 km h, ......Or even higher, at this time, the ECO mode will no longer be able to play a fuel-efficient function. In addition, the vehicle will not function when it is parked and idling.

Since ECO mode can save fuel consumption, why do car owners not turn it on, thinking that it will bring harm to the car?

For many car owners, there is basically no ECO mode when driving, and there is only one reason, and that is that the power is weakened, which is a typical sacrifice of power to save fuel consumptionAccording to what I said above, I don't feel anything when I go down the throttle, the power boost is not fast, and it is completely limited.

In addition to the weakening of power, it is also easy to accumulate carbon, because the car has been driving at low speed for a long time, it is inevitable that there will be insufficient combustion, which will lead to carbon deposits.

eco:economic means, that is, economic. This button indicates that the owner can choose an economical way to drive the car:

The principle is to select this mode, and the driving computer automatically adjusts the valve opening and closing speed to achieve the purpose of fuel saving. However, it will have a certain impact on the power, which is manifested in the sluggish reaction of the throttle speed.

The ECO is an indicator that indicates the vehicle's refueling status while driving. When the ECO green light is on, it means that you are driving in a fuel-efficient state, and when the ECO light is off, it means that your vehicle is not driving on fuel. When you turn on ECO mode, the ECO will not light up when you press the accelerator throttle or drive over 120 yards.

The main role of the Eco is to develop good driving habits, i.e. not to slam on the accelerator.

Hello, eco is the economical fuel-saving mode, when this function is turned on, the instrument will appear with the word eco, at this time the gearbox will reduce the speed to shift gears, to achieve the purpose of fuel saving! This function is recommended to be used on congested roads in the city, and when running at high speeds, it is personally recommended to turn it off, so that the power will be better.

ECO is an energy-saving mode, and you can save energy by activating it.

Energy saving mode. This feature is available for mid-to-high-end vehicles.

ECO is whether the speed, gear, and speed of your car are in the most economical cooperation after starting this mode, and the overall fuel consumption is not the most economical.

That's a sign of economy and energy saving.

Yes, the energy-saving mode is turned on.

How to close the dashboard eco, it turns out that eco is what it means, and it is considered to have been learned.

It prompts this to enter the lift mode, the commonly known maintenance mode of maintenance.

1: The car will suddenly turn off during slow driving or when parking and idling (there is no stalling during fast driving). At first, I thought it was a problem with the spark plug, because after all, it has not been replaced, after replacement, the problem is still the same, and then the throttle valve was cleaned, and the natural gas system was checked, and the problem was still the same.

Today in the drive, there was a fire extinguishing again (suddenly extinguished the fire, without any warning, the engine speed was also very stable), and then I restarted, the first time I started the car has been igniting, about 4 seconds over, stopped ignition, the car has been energized, but the car has not started, the second time the ignition, the car started smoothly, but the idle speed gauge did not respond, but the car can be driven, I re-ignited when waiting for the traffic light, everything is normal again. I immediately drove to the garage to monitor the engine, and the computer showed that everything was fine. Now this situation has occurred many times, and the problem has not been found, which is very strange, please advise!!

2: When the vehicle is driving in the range of 70-90 kilometers per hour, the body shakes, it feels a bit like resonance, and it is smooth below 70 or above 90. The car did dynamic balancing and four-wheel alignment years ago, and the wheels and tires were just replaced 1 year ago.

I went to the garage for monitoring, and inspected the engine cushion rental, half shaft, tie rod, ball joint, etc., except for the slightly empty frame of the tie rod, no other problems were found.

Failure of the recorder's battery aging or failure of the car's power supply line.

The car's dashboard shows the key, which means that the key is not detected.

The display of the key on the vehicle instrument is caused by the fact that the computer board in the car cannot detect the signal of the key remote control.

Solution: 1. Press the lock button and unlock key of the key.

2. Replace the battery of the key.

The display of key on the car instrument indicates that the vehicle has not detected the key, or indicates that the key is faulty.

Key out literally means that the key is not in the car Usually the car dashboard shows that the smart key is not in the car or within the effective distance. If the key is in the car, then please check the battery level of the key, but the lack of power will not start the engine or open the door.

In general, the instrument displays the key, which means that the vehicle cannot recognize the electronic key. That is, the signal of the key is not accurately recognized by the vehicle.

The principle is not difficult to understand: the chip built into the electronic key will send a wireless signal, and the vehicle's computer has a receiving module. If the signal is not received, or the received signal is intermittent, the meter will alarm the key.

Usually, the most common reason is that the battery power of the key is not enough. In the case of insufficient power, the ability of the key to send a wireless signal is much weaker. As a result, the vehicle's computer cannot reliably read the information.

We just need to replace the key battery to solve the problem.

In addition, if the transmitting antenna and circuit in the key are **, it will also cause poor signal transmission. In addition, problems with the receiving module of the vehicle's computer can also lead to poor signal transmission.

Can you still take a taxi?

The key is dead.

Fault: When starting the vehicle, the ignition switch cannot be turned on, and the key light on the dashboard lights up at the same time.

Analysis: First of all, ensure that the card key is located in the space in the car (either in the car, or on the body of the driver and passenger who enters the car); Second, it is possible that the owner of the car stopped the car in the previous time and turned off the steering wheel when leaving the door to activate the lock function. While hitting the steering wheel counterclockwise with your left hand, you should be able to unlock the steering wheel to start the engine.

What color is red means that the car key leaves the car and green means that the key signal is received.

Is it the reason why the green key on the meter keeps flashing?

As soon as the car starts, the key is displayed on the dashboard.

When the tire pressure warning light is on, it means that the current four tire pressure deviations are too large and less gas, indicating that there is a problem with the tire pressure of the vehicle, and it is recommended to check it.

1. The tire pressure monitoring light is on due to the tire being punctured.

This situation is usually very slow air leakage, for a while can not find out which tire is it, at this time you can use the tire pressure gauge to measure, front, rear, if there is a lack of air, make up, and then observe the tire pressure warning light, if a few days later and on, it may be necessary to pick up the tire to check. 4S shop, the usual way for maintenance personnel to deal with it is to adjust the pressure of the two front tires to, adjust the pressure of the rear tires, and then cut off the tire pressure alarm, and let us run another day to see, if you don't call the police again, it will be no problem, and then call the police may have a tire that has been punctured, and you need to go to the 4S shop again, so that they can help check and check.

2. The tire pressure monitoring light is on, sometimes the tire pressure is too high.

Generally, the international GBT 2978-2008 standard stipulates that the inflation pressure of automobile tires meets the requirements of Table 1-Table 15:

Standard tires:; Reinforced tires:; Maximum air pressure: should not be greater than. Therefore, when a tire exceeds it, it will also trigger the tire pressure monitoring light to turn on.

3. The tire pressure monitoring light is on due to low tire pressure driving time for too long.

This situation usually occurs when the tire pressure of a tire is too low, and the tire temperature rises due to high-speed operation, which causes the tire pressure to rise, and then the tire pressure rises, so you should stop and rest in time or replace the spare tire.

4. The tire pressure monitoring light is on due to the low tire pressure that has not been refilled for a long time.

When the air pressure is lower than the bottom, the tire pressure monitoring light is on, so you should usually do a check to see if the tire pressure detector is normal. When the car is in trouble, if the tire pressure monitor does not alarm in time, it is a problem with the tire pressure monitor; If the ignition switch is on start, the indicator light point and the TPMS indicator light will be on at the same time for 2s and then turn off. In this case, either the original receiver of the vehicle has not been learned, or the receiver controller has been replaced, and the receiver controller has not been learned.

You can go to the 4S store and ask professionals to use handheld learning tools to re-obtain all tire sensor IDs and bind the receiving controllers.

Stop and check if the tire pressure is normal. When encountering the tire pressure system alarm, stop on the side of the road first, get out of the car to check the tire pressure of the four tires, if there is no obvious loss of gas with the naked eye, you can ignore it, and then reset the tire pressure system after getting into the car, so that the alarm light goes out. After continuing to drive for a period of time, if the tire pressure warning light is lit again, it means that there is indeed a problem with the tire pressure of a certain tire, and it needs to be checked and repaired in time.

If the tire pressure monitoring system warning light is on during driving, stay calm, don't panic, immediately reduce your speed and avoid hitting the steering wheel and braking hard, and check your tires immediately.
