How to reset a check for a Hyundai Solaris: resetting errors with your own hands. Hyundai Solaris: Control lamps and indicators

It often happens that on the instrument panel in the passenger compartment of a car equipped with electronic control, the warning light comes on. If the car starts up, continues to work, but the check engine light is on, this means that the switch-on occurred in emergency mode. Some models modern machines(Audi, BMW, Mercedes-Benz, Porshe, VW) are equipped with a system capable of self-diagnosis, errors are decoded to the information panel. But drivers are not always able to understand why the check engine malfunction lighted up.

To start the engine, the driver turns on the ignition. If at the same time the engine check is flashing, this should not cause concern, since it will soon go out. But a burning signal, with the engine running, indicates violations in its operation.

In the event of a malfunction in the operation of the power unit, an error is recorded in the memory of the control unit in the form of a coded signal. In this case, the check engine light is on the dashboard. If the car does not provide diagnostics in automatic mode, you need to connect a device for scanning to a special connector. The scanner reads the code and performs detailed transcript errors.

In the development of electronics, the indicator check engine has evolved from a simple fault sensor into a signaling device with many functions. A modern engine check, when blinking, reports the following inconsistencies:

  • incorrect composition of fuel mixtures;
  • failures of settings in the ignition system;
  • sensor failures.

It is also his job to report problems that are not related to power unit. To identify the place of occurrence and nature of the breakdown, the master will need professional knowledge, experience, special tools and tools.

Important: The electronic unit The ECU gives a command to flash the signaling device, as a result of detecting errors of varying degrees of complexity. Among them, there are problems, both serious and minor. For the purpose of diagnostics, it is recommended to suspend operation vehicle. Experienced car owners often independently determine the reason for the inclusion of a check, without waiting for a visit to the service station.

Signs of major malfunctions and the causes of the indicator signal

If the check Engine light comes on while the car is moving after refueling at a gas station, the most likely cause is the inappropriate quality of the filled gasoline. In this case, the following symptoms are observed:

  1. Power reduction.
  2. Interruptions in the engine (stalls).
  3. Detonation as a result of incomplete combustion of fuel.
  • add a portion of higher quality fuel to the tank;
  • drain the recently filled gasoline, clean the fuel system.

If the check does not want to go out after the cause has been eliminated, it is necessary to delete the error recorded in the device’s memory using a special computer program.

Checking the oil level and its condition

The next most important causes of the signal are considered to be overheating of the motor, a decrease in the level lubricating fluid in the DVS. It is recommended to check the engine temperature. If there is no overheating, check the volume and condition of the oil. After checking the level, it is necessary to add the missing amount lubricant. Using a clean paper towel, the quality and composition are checked. engine oil according to the following criteria:

  1. Color.
  2. Consistency.
  3. The presence of mechanical inclusions.
  4. The smell of burning.

If everything is in order with the quality and quantity of oil, the engine starts to eliminate unusual sounds, noises during operation as in the idle move as well as under load.

If you detect unusual noise effects of a running engine against the background of a burning check, it is recommended to send the car to the nearest service company. Self-moving a car is not recommended, delivery is carried out by towing or in another convenient way. Further operation can lead to serious damage and costly repairs to the elements of the power unit.

Flashing indicator and engine tripping

When the check is flashing and the engine is troit at the same time, it is necessary to examine the elements of the ignition system:

  • wiring;
  • coil.

The tripping effect occurs when only three combustion chambers are working instead of all four. The engine starts to triple in the absence of injection of the air-fuel mixture into one cylinder.

Worn out and dirty spark plugs also cause the Check Engine light to come on. In order not to think for a long time how to remove the engine check, you just need to clean or completely replace outdated candles with a new set.

Checking the ignition coil is reduced to measuring the resistance at the terminals and testing for the ability to create a blue spark.

What to do if the check engine light is on due to a malfunction in the fuel supply system

In case of violations associated with the flow of fuel into the cylinders, it is recommended to check the condition of the spray nozzles. Their holes must be cleaned, washed, if necessary, completely replaced with new devices.

Pressure drop in fuel system caused by malfunctions:

  1. Gasoline pump (in carburetor, injection engines).
  2. fuel filter
  3. High pressure fuel pump (in diesel).

If the check engine light is caused by a failed catalytic converter, drivers simply remove it from the exhaust system and then turn off the corresponding sensor (oxygen).

How to reset check engine error

If critical errors occur in the operation of the engine, the information is recorded in the ECU memory and is not deleted on its own even after the defect has been eliminated. In this case, the check continues to glow. To reset a recorded error with your own hands, experienced car owners perform the following operations:

  • warm up the engine to operating temperatures;
  • disconnect the terminal battery for a while (from 5 to 15 minutes);
  • restore the connection with a terminal;
  • insert and turn the ignition key before starting (while all the indicators on the devices are on);
  • wait one minute;
  • turn the key in the opposite direction.

Most often, such actions lead to the desired result, the error code disappears from the memory of the computer unit. The check stops glowing after turning on and running the engine in idle within three minutes.

If the method of disconnecting the terminal did not work, the indicator continues to flash, the error is removed from the memory of the control device using special computer programs through the pinout OBD diagnostic connector.

The control unit can also cause the check signal to turn on if individual elements of the computer partially or completely fail.

If on dashboard If your car’s Check engine light comes on (or the “check” is simply on), you should at least be alert. The reasons for this can be very diverse - from a loose gas tank cap to serious problems with the engine.

What does the Check engine indicator mean?

The name of the Check engine indicator literally translates as "Check the engine." However, the engine, when the light comes on or flashes, can be completely irrelevant. A lighted indicator may indicate problems in the fuel supply system, failure individual elements ignition, etc.

Sometimes it can be a very minor problem - for example, a loose gas tank cap or a catalytic converter malfunction. Nevertheless, it is impossible to ignore the indicator signals in any case, as this can turn into serious problems.

Sometimes the cause of the light coming on may be poor fuel quality. So do not be surprised if after refueling at an unfamiliar gas station you see the Check engine light flashing.

Usually the indicator is located on the dashboard of the car under the engine speed indicator. It is indicated by a schematic engine or a rectangle labeled Check engine or simply Check. In some cases, instead of the inscription, a lightning sign is depicted.

Can you keep driving with the light on?

Worn out brake pads, it's time for the next maintenance, the speed is switched incorrectly, poor quality fuel is used, the voltage has dropped onboard network- all this can cause the Check indicator to light up. First of all, you should check the motor. If the cause of the alarm is engine malfunctions, it is dangerous to continue driving.

The problem is exacerbated by the fact that independently determine the malfunction modern internal combustion engine by smell or color is impossible. You should contact professionals who, using a scanner, will identify a malfunction, if, of course, there is one.

burning light bulb Check may indicate various breakdowns - it is better not to ignore it

Therefore, if the light does not go out after restarting the car, you can only drive it to the nearest car service. They will conduct a comprehensive diagnosis of the engine and its systems.

Operating a vehicle with a lit Check engine icon will result in increased consumption fuel, unstable engine operation, lower traction characteristics car. Moreover, in this case, the car owner may lose guarantees for car repairs.

Why the light came on and how to fix it

The main situations in which the indicator lights up, and the recommended course of action for the motorist:

  1. If the check engine lights up when starting the car and immediately goes out, there is no engine damage. The cause of the fire is most likely harmless - the loss of the fuel tank cap or its underscrewing. It is enough to wrap it tightly and check if the warning has disappeared.
  2. If the indicator lights up while driving, you should stop and check the wires. You may find a cable hanging loose under the hood or an open battery terminal. This applies to all attachments - wires, hoses, etc.
  3. If the light flashes while driving, you should stop and check the sounds made by the engine, pay attention to the oil level, inspect the sides of the motor. If visually obvious violations are not found, it is recommended to drive to the nearest car service and carry out diagnostics.
  4. If the engine is running normally and the Check light is constantly flashing, the ignition has most likely failed. You should check the candles and the coil, pay attention to the quality of the fuel. To do this, it is better to contact the nearest auto-diagnostic center.
  5. If the indicator is constantly on, you need to stop, unscrew the candles and check the gap. Gaps that exceed 1.3 may cause the bulb to light up.
  6. In addition, when the check is on, the ignition is usually checked. In any car service there are special testers that allow you to determine the deterioration of the wiring insulation.
  7. The cause of the light bulb catching fire can also be a faulty fuel pump. You should stop and listen to the sounds made by the fuel pump. A smooth buzz without clicks and pauses is considered normal. If they appear extraneous sounds, the pump should be dismantled, rinsed from the inside and clean the filter.
  8. Serious engine problems can be indicated by coolant temperature. If it is above 85–90 degrees, and the Check engine lights up while driving, the engine is definitely faulty. In this case, it is advisable to call a tow truck or drive at low speed to the nearest car service.

We have already noted that Check lights up every time the engine is started in yellow or orange. It is normal if the flashing lasts no more than 3-4 seconds and stops along with the flashing of other indicators on the dashboard. Otherwise, follow the steps above.

Resetting or resetting the Check indicator

In most cases, as the table shows, Check lights up when a sensor fails or the vehicle's operating conditions change. However, even after diagnosis and troubleshooting, the light sometimes continues to burn.

The fact is that the "trace" of the error remains in the computer's memory. In this case, you should "reset" or "zero" the indicator readings. This can be easily done on your own by performing a number of simple operations:


The sensor is zeroed, and the Check light is no longer on. If this does not happen, contact the service center.

The check engine light on the dashboard almost always requires the vehicle to be stopped immediately. Using the recommendations given in the article in practice will help you avoid complicated and expensive engine repairs. Good luck on the roads!

Check engine light on - causes

The main reason for the indicator to light up - an engine error is to fix serious problems with the control unit in the engine. Movement in this case is possible if the check engine light is on and the indicator does not blink, the behavior of the car itself remains unchanged, as well as the engine power and its response to pressing the gas pedal, and also if the other error indicators indicating the presence of any or problems, "silent". It is also worth paying close attention to the level of coolant and oil; their number should not change dramatically. But even in this case, it is worth getting to the car service as soon as possible.

Driving when the indicator lights up - engine error is prohibited in several cases:

  • The car changed its behavior on the road;
  • The power of the motor has decreased, you feel its vibrations;
  • You smelled burnt;
  • The "engine service" light is intermittent (flashing);
  • The emergency oil level indicator lights up;
  • The engine overheat warning light came on.

An engine error can cause serious damage. And, worst of all, a car dealer may refuse to perform free warranty repairs.

Check Engine is on - what to do?

In the event that the emergency oil level indicator lights up while driving, you should immediately turn off the engine. After that, it is necessary to check the oil level, and if it is below the permissible value, it is worth adding oil and trying to start the car again. If, adding oil, did not change the situation (the engine check is still on), in this case it is worth contacting a car service. The main thing to remember is that you should never try to get to a car service in your car if you do not want your engine to suffer serious damage when running without lubrication.

The onset of overheating can be signaled by an indicator responsible for warning the driver about high temperature liquid in the expansion tank, and the displacement of the pointer, reflecting the temperature of the liquid, towards higher values. If the pointer has not reached the red zone, which means that expansion tank still has a sufficient supply of liquid, and there are no signs of "dangerous overheating", reduce temperature regime You can do it yourself by doing a few simple steps:

  • Reduce vehicle speed;
  • Do not use air conditioner;
  • Turn on the heating to allow the engine temperature to drop. If after turning on the stove, hot air does not start to flow, stop immediately. These are the first signs of "dangerous overheating".

In addition to the above methods for detecting “dangerous overheating”, there are a number of others: the presence of steam coming from under the hood of the car, lowering the engine power level, an empty expansion tank, failure heating system when outside (cold) air begins to enter the passenger compartment.

When the ignition key is turned to the oN position, all indicator lamps are checked for correct operation (do not start the engine). Any lamp that does not light up should be checked by an authorized HYUNDAI dealer.

After starting the engine, make sure that all control lamps are off. If any of them remain lit, this indicates a situation that needs attention. When the parking brake is released, the parking brake indicator lamp should go out.

Pilot lamp low level fuel will continue to burn if the fuel supply is insufficient.

ECO (ECO indicator, if equipped) ( automatic box gears)

ECO-indicator - a system that allows you to drive a vehicle in economy mode.

The indicator is displayed when the fuel consumption is economical, which can improve fuel efficiency.

ECO indicator (green), lights up when fuel is used efficiently in eCo oN mode.
The display of the ECO indicator can be turned off by pressing the TrIP button. Turning ECO mode on and off is described on the previous page.
Fuel economy depends on driving style and road conditions.
This function does not work in non-economy driving conditions such as P (Park), N (Neutral), or r Reverse.
If the display shows the current fuel consumption, the eCo indicator turns off.

CAREFULLY

Do not watch the indicator while driving. This distracts from driving and may cause an accident resulting in serious injury.

Airbag Warning Light (If Equipped)

This warning lamp comes on for approximately 6 seconds each time the ignition key is turned to the oN position.

This lamp also comes on if there is a malfunction in the airbag system. If this lamp does not come on or stays on 6 seconds after turning the ignition key to oN or starting the engine, or if it comes on while the vehicle is moving, have an authorized HYUNDAI dealer check the condition of the airbag system.

Seat Belt Warning (If Equipped)

As a reminder to the driver and passenger, the seat belt warning light will illuminate for 6 seconds each time the ignition key is turned to the oN position, whether the seat belts are fastened or not.

For details, refer to “Seat Belts” in Chapter 3.

Pilot lamp insufficient pressure engine oil

1. Being careful, move to the edge of the roadway and stop the car.
2. With the engine stopped, check the oil level. If the oil level is low, add oil as required.

If this warning light remains on after adding oil to the engine, or if there is no oil available, contact an authorized HYUNDAI dealer.

ATTENTION

If the engine is not stopped immediately after the low engine oil pressure warning light comes on, the engine may be seriously damaged.

ATTENTION

If the low engine oil pressure warning light comes on while the engine is running, severe engine damage may result. This lamp lights up if the pressure in the lubrication system drops below normal. Normally, it lights up when the ignition is turned on and then goes out after the engine is started. If the low oil pressure warning light comes on while the engine is running, this indicates a serious problem.

In such a situation, stop the vehicle as soon as it is safe to do so, stop the engine and check the oil level. If the engine oil level is low, top up the oil to the correct level and start the engine again.

If the lamp stays on while the engine is running, stop it immediately. In any case, if the low engine oil pressure lamp is on while the engine is running, before starting the engine again, you should contact an authorized HYUNDAI dealer to check the condition of the car.

Parking brake warning lamp and insufficient level brake fluid

This lamp comes on when the parking brake is on and the ignition key is in the START or OFF position. This lamp should turn off when the parking brake is released with the engine running.

Low Brake Fluid Warning

The glow of this control lamp indicates an insufficient level of fluid in the reservoir of the brake system.

If this indicator lamp is on:

1. Using caution, turn into the nearest safe place and stop the vehicle.
2. With the engine stopped, immediately check the brake fluid level and top up as required.
After that, check all elements of the brake system for leaks.
3. Do not continue to move the car if leaks are detected, if the control lamp continues to burn, or if the operation of the brake system is abnormal. The vehicle should be towed to have the brake system checked and the necessary repair work authorized HYUNDAI dealer.

This vehicle is equipped with a dual diagonal brake system.

This means that even if one of its lines fails, the brakes on two wheels of the car will be in working condition. In such a situation, to stop the car, you will need greater stroke brake pedal and more force on it.

Besides, braking distances a car with only part of the brake system working will be more than normal. If the brakes fail while the vehicle is moving, shift to a lower gear for engine braking and stop the vehicle as soon as it is safe to do so.

To check the operation of the Parking Brake and Low Brake Fluid Warning Lamp, verify that it illuminates when the ignition key is turned to the oN position.

CAREFULLY

It is dangerous to drive a vehicle while the warning light is on. If the brake system warning light remains on, have the brake system checked and repaired immediately by an authorized HYUNDAI dealer.

Anti-Lock Braking System (ABS) Warning Light (If Equipped)

This lamp comes on when the ignition key is turned to the oN position and goes out after about 3 seconds if the system is normal.

If this lamp remains lit after the ignition is turned on, lights up while driving, or does not light up after the ignition is turned on, this indicates a possible malfunction of the AbS system.

In such a situation, you should contact an authorized HYUNDAI dealer as soon as possible to check the condition of the vehicle.

The braking system of the car will continue to function, but without the support of the anti-lock system.

Electronic brake force distribution (eBD) warning lamp

If two warning lamps come on at the same time while driving, the vehicle has a faulty and AbS system, and the ebd system.

In this case, the AbS system and the main brake system may operate abnormally. You should contact an authorized HYUNDAI dealer as soon as possible to check the condition of the vehicle.

CAREFULLY

If both the ABS warning light and the brake warning light come on and stay on at the same time, the vehicle's brake system will not work properly during hard braking. In this case, avoid driving at high speed and sudden braking. Have your vehicle checked by an authorized HYUNDAI dealer as soon as possible.

FOR YOUR INFORMATION

If the ABS or eBD warning light comes on and stays on, this may indicate a problem with the speedometer or trip odometer/odometer. In such a situation, you should contact an authorized HYUNDAI dealer as soon as possible to check the condition of the vehicle.

Electronic Stability Program (ESP) indicator (if equipped)

This indicator comes on when the ignition key is turned to the oN position and should go out within about 3 seconds. When the eSP system is enabled, it monitors the vehicle's driving conditions. If conditions are normal, this system indicator is off. When entering a slippery road surface or when the tire grip decreases, the eSP system starts to work.

At the same time, its indicator starts flashing, informing about the operation of this system.

But in the event of a malfunction of the eSP system, the indicator lights up and does not turn off. In such a situation, you should have the vehicle checked by an authorized HYUNDAI dealer.

Essence of the question: How to reset the "CHECK"?

Hello! I have a Hyundai Solaris, and the "check" light is constantly on! I already went to the station Maintenance and found out what the problem is. The first time they dropped it to me, and now it has appeared again, while the behavior of the machine has not changed in any way. Tell me, please, how can I reset it myself, because I don’t want to pay for it again in the service.

If the CHECK light comes on when starting the engine, then there is no need to worry. But if the check is on when the engine has already started, then you need to find out the cause of the error.

The owner of the vehicle may need to diagnose and remove errors that occur on the Hyundai Solaris in various situations when there is no desire to do this work in a certified service center.

It is not difficult to do this work, the main thing is to know that you can remove it yourself errors related to the first level , that is, those that are not recorded in the memory of the computer, which do not significantly affect the operation of the car and its devices. Since only a special dealer device (scanner - approx.) can remove such errors, one of these errors is a car airbag error.

When are errors removed on their own?

Among all the important problems on the Hyundai Solaris, some can be reset on their own after one or another repair.

For example, error codes with 301 By 304 , indicating a spark gap in one of the cylinders (the last digit of the error refers specifically to the cylinder - approx.).

If the error indicates a misfire in the cylinder, first look at the condition of the spark plug. In the photo, the candle is the culprit of this error.

Accordingly, when these gaps are detected, the ECU will give a signal in the form of a burning “CHECK”, which cannot be removed without erasing the code or resetting the terminal from the battery.

This error is completely removed, only by replacing the non-working candle with a new one, after which the error will disappear by itself.

Self reset check for Hyundai Solaris

Resetting errors on your own on a Hyundai Solaris is possible thanks to the OBD-II protocol and the presence of a special adapter with a diagnostic device, whether it is a smartphone or a computer that supports Bluetooth wireless technology.

In order to check the errors on the car, perform the following steps:


Standard window for checking and clearing errors of the Scan Master program

The process of diagnosing and resetting errors without OBD-II

On Hyundai Solaris, you can diagnose and remove errors without even having any additional devices at hand.

Diagnostics (this method does not work)

The method described below runs all over the Internet. We tested on our drafting machine. He does not work. We do not delete the method, as some owners may think that it works.

Video disclaimer:


Removing errors

  • In order to remove the error, it is necessary to do the entire above-mentioned course of work from points 1 to 5, and without turning off the ignition, press the "gas" again.
  • After that, turn off and turn on the ignition, start the engine.
  • If the progress of the work was done correctly, the error should be removed.

As you can see for yourself, there is nothing difficult in removing an error on a Hyundai Solaris on your own.
