How to install and activate cruise control on Lada Granta FL (new generation)

• Find a programmer and download a special application to your PC.
• Mount the utility on your computer and connect it to the car via the programmer.
• Install additional power wires according to the factory diagram.
• The system is activated and the firmware procedure begins.
• Next, you must strictly follow the manufacturer's instructions.

Firmware on Standard version

For a standard modification of a car, the utility version 2190-00-040 or 042 is used. From here you can safely flash versions up to 076. Also, in some modifications of a Norma-type car, you may also encounter an assembly like 219020.

Firmware for Norma configuration

The steps and tools here are similar to the Standard assembly. To understand which firmware version is in stock, you should enter the required combination on the machine specified by the manufacturer.

Re-flashing the panel Grants FL

Nothing changes when you try to upload a new program to the flap of the FL version. The actions are completely identical. The only difference is the version of the utility itself.

Using the Scanner

Using a scan tool is the easiest way to reset your check engine light. Here are 5 simple steps:

• Connect the scan tool to the OBD connector under the steering column. A laptop or tablet with the appropriate software is installed in the holder;
• Then turn on the car’s ignition and turn on all the gadgets accordingly;
• On your mobile device, in the appropriate section, press the “READ” button to view engine error codes. We write down the codes with a pen in the order in which they were received. This will be necessary for subsequent repairs.
• We delete the error code. Press the “ERASE” button on the scanner. The Check Engine light will turn off when all error codes are cleared. Some scanning tools have many options, such as freeze frame, which captures the sensor readings. When deleting codes, these readings will also be deleted. Note: in some scanners, the option to clear codes may be automatic and the “CLEAR” or “YES” button instead of the “ERASE” button.
• Be sure to turn the ignition on before clearing codes.

Frequently asked questions about auto diagnostics via a computer or smartphone

Engine diagnostics

The capabilities of engine diagnostics via the OBD2 connector depend on the scanner and software. For example, a simple amateur adapter ELM327, together with the OpenDiag application on a smartphone, allows you to read engine errors and decipher them, as well as view temperature sensors and engine speed, both at idle and while driving in real time.

We provide documentation for engines with electronically controlled throttle valves that meet toxicity standards. Read the files by running engine diagnostics.

ABS diagnostics via OBD2 connector

If problems arise with the ABS, before changing or manually diagnosing the problem, read the errors according to the instructions provided. Checking for errors will show you not only the condition of the sensors, but also the wires and connectors.

Diagnostics of mass air flow sensor

Using the Open Diag program, we record the voltage at the mass air flow sensor. The permissible voltage values ​​are:

• if the sensor is in good condition, the voltage is from 1.01 to 1.02 V;
• in satisfactory condition - from 1.02 to 1.03 V;
• a value ranging from 1.04 to 1.05 indicates a near-death state

Important: If it exceeds 1.05 V, the mass air flow sensor requires replacement!

Diagnostics of the oxygen sensor (lambda probe)

The oxygen sensor is checked using the Open Diag program and an adapter connected to the OBDII connector. We analyze the voltage values ​​at the sensor.

When the engine is running, the voltage should change from 0.008 to 0.7V and back. There should be no smooth declines or freezes on the oscilloscope.

Automatic transmission diagnostics

Diagnostics of the gearbox is also possible, but limited by the Granta ECU itself. Yes, you can use professional, expensive car scanners, but we are talking about self-checking.

Using an adapter and an application on a smartphone, you can see errors in the transmission; if there are any, their decoding will indicate one or another malfunction of the box. Also, in real time, data from temperature sensors is taken from the box.

Automatic transmission errors:

P0720 “Output shaft speed sensor is faulty” P0717 “Turbine speed sensor” P0706 “Automatic transmission selector. No signal" P0705 "Automatic transmission selector. Several signals at the same time" P0974 "On-off solenoid. Open circuit" P0973 "On-off solenoid. Circuit shorted to ground" P0963 "Pressure control solenoid. Open circuit" P0962 "Pressure control solenoid. Circuit shorted to ground" P0740 "LOCK UP SOL(Open)" P0743 "LOCK UP SOL(GND short)" P17AB "L/C SOL(Open)" P17AA "L/C SOL(GND short)" P17AE "2-4 /B SOL(Open)" P17AD "2-4/B SOL(GND short)" P17B1 "H/C&L&R/B SOL(Open)" P17B0 "H/C&L&R/B SOL(GND short)" P1735 "INTER LOCK FUNCTION (1st)" P1736 "INTER LOCK FUNCTION(2nd)" P1737 "INTER LOCK FUNCTION(3rd)" P1738 "INTER LOCK FUNCTION(4th)" P0744 "LU CLUTCH(Lock-up)" P1744 "LU CLUTCH(Slip Lock-up) )" P0731 "Incorrect automatic transmission ratio in 1st gear" P0732 "Incorrect automatic transmission ratio in 2nd gear" P0733 "Incorrect automatic transmission ratio in 3rd gear" P0734 "Incorrect automatic transmission ratio in 4th gear" P17A1 "NEUTRAL FUNCTION(1st)" P17A2 "NEUTRAL FUNCTION(2nd)" P17A3 "NEUTRAL FUNCTION(3rd)" P17A4 "NEUTRAL FUNCTION(4th)" P17A0 "NEUTRAL FUNCTION(Rev)" P0712 "Oil temperature sensor, low reading" P0713 "Oil temperature sensor, high reading" P0711 “Oil temperature sensor, frozen” P0863 “CAN bus connection (initialization)” P062F “BACKUP MEMORY” P1701 “Controller supply voltage”

Diagnostics and testing of the electronic gas pedal

VAZ supplies LADA GRANTA cars with an electronic gas pedal (E-gas) to comply with modern environmental standards.

If the pedal is malfunctioning (no responsiveness or increased engine speed when changing speed on the gearbox), then before dismantling and checking the unit with a multimeter, read the errors through the OBD2 connector.

Typical errors related to the accelerator pedal:

• The “Check Engine” light came on on the dashboard (error 0504);
• Error: Low/High signal level of the first accelerator pedal sensor.

Removing errors will not help here; you need to eliminate the cause of the breakdown and only then erase the errors. If errors are indicated and the pedal does not work stably, you should adjust the sensitivity of the gas pedal itself, it should become more responsive.

EUR - electric power steering

If the EPS diagnostic light comes on or the EPS periodically turns off/on, you should first check the electric power steering through the diagnostic connector.

The same Open Diag application, together with a diagnostic OBD2 adapter, will help with this, or

other scanners: Scanmatic, ScanDoc, Motor-Master. The diagnostic process boils down to identifying errors, decoding them and further repairs according to the type of malfunction.

The check can also be performed without a scanner, in this way:

1. Under the steering wheel, near the ignition switch, you should find an 8-pin black connector. You will need to dismantle the casing at the steering column (unscrew the fastening screws from the bottom).
2. Next, insert a paperclip and close the two contacts, as in the first photo at the beginning of the article. (these are contacts No. 6 and No. 7).
3. Turn on the ignition and look at the control lamp.
4. The first signal is a long lamp burning - “1”
5. Next, we count the subsequent short signals, if there are 3 short ones then “3”.
6. In our case, the result was code “13”.

Battery disconnect method

Disconnecting the battery is an old way to reset the check engine light. Here are three steps to clear the check using this method: Step 1: Disconnect the cables from the battery. At this point, you should use a wrench to unscrew the positive and negative cables.

Step 2: Discharge the remaining electricity. The next thing you should do is press and hold the car horn for about 30 seconds. This action will help drain the car battery.

Step 3: Wait and reconnect the battery. After disconnecting the battery cables and draining the remaining electricity, all you have to do is wait about 15 minutes and then plug the battery back in. Error codes will be cleared. (Note: This method may not work on some vehicles.) If after this procedure the “check” lights up again, this may mean that the problem is still much more serious.

The main reasons for increased fuel consumption

On specialized forums you can find messages from people who complain that their Lada Granta, according to the on-board computer in the city, consumes 12, and sometimes 13 liters of fuel per 100 kilometers. Why then, one wonders, does one car consume 7.4 liters, and the other 12? The answer is very simple. To more accurately measure fuel consumption, you need to drive at least a thousand kilometers and check the consumption, which is called “by receipt” or “from light bulb to light bulb.” How to do it? We are waiting for the fuel remaining lamp to light up - this means that you have less than 7 liters of fuel in the tank. We fill the tank full or the required amount of fuel, measure the mileage and wait until the fuel remaining lamp comes on again. In this way we refuel and measure until we travel a thousand kilometers. Next, we calculate the consumption using a simple formula: (Amount of fuel / Mileage) * 100 = average consumption.

Allow the check engine light to go off on its own.

Wait until the “check” goes out on its own. The simplest method because you don't have to do anything. The computer system in most vehicles will automatically recheck for problems that may activate the error light. If it is a minor problem, it will automatically correct itself and the check will go off. However, if the check light is still on after three days, you need to apply the methods mentioned above to reset it.

If this continues to happen despite the following reset procedures, you should take your vehicle to your nearest auto repair shop and have it diagnosed by a professional mechanic. Professional diagnostics use more sophisticated tools and can identify precise problems.

Procedure for resetting an error using an OBD2 adapter

1. Connect the adapter (for example, ELM327 car scanner) to the OBD2 connector of your car. A guide on how to connect the adapter and diagnose the car is described in detail in the article.
2. Using a portable mobile device on Android or iOS and a special diagnostic application, reset the errors in the ECU, as shown in the screenshots (the Torque program was used).

Attention! Reset errors with the engine off!

After carrying out this manipulation, the Check Engine error should go off on the dashboard. You may need to turn the ignition off and on.

Resetting Check Engine without OBD2 adapter

The method is completely free, but to do this you will have to climb into the engine compartment.

1. With the engine off and the ignition off, disconnect the battery (simply remove the terminal).
2. Turn on the headlights to remove any remaining current (usually waiting a few seconds is enough, sometimes it takes a few minutes).
3. Turn off the headlights, replace the battery terminal and start the engine.

By depriving the on-board computer of current, we reset the errors stored in the memory of the electronic control unit (ECU).

Probably every owner of a car with an injection engine has encountered various errors in the operation of this unit. This trouble is indicated by the corresponding sign on the instrument panel - “engine error”. Many will immediately go to the service station for diagnostics, while others will drive with this problem. But the third group of people will definitely be interested in the reasons and deciphering of the codes.

Advantages of the digital panel

The manufacturer Ferrum offers an original solution: the panel combines the standard functions of an analog instrument panel and an on-board computer. A car owner who decides to change the instrument panel to a digital one benefits in price and design. For a reasonable price, he gets a stylish shield containing more than 100 functions. Not every on-board computer has similar parameters.

• the panel does not require re-wiring;
• you can install it yourself;
• the cost is comparable to the price of a high-quality on-board computer.

The main advantage is detailed text information about the error that occurred. The on-board computer is only capable of issuing codes that the owner of the car deciphers independently.

There is a tachometer in the middle of the display. This once again emphasizes the sporty nature of the design. The graphic display with a resolution of 128×64 has an image inversion function.

ECU in cars

The operation of the mentioned part is invisible, but this unit starts immediately after the driver turns on the engine.

Each ECU on any car is equipped with a special controller, which, when various malfunctions are detected, responds to them by lighting the “engine error” indicator. Each error has its own code and remains in the computer's memory. Some problems are not only completely saved, but the time they were detected by the system is also recorded. This option is called "freeze frame".

conclusions

The reasons why the “CHECK” function lights up on the Lada Grant are quite simple, since this sensor is responsible for the full operation of the engine. To identify the causes, it is worth conducting a diagnosis and determining why this happened, and only then eliminating it.

All modern cars are filled with electronics, and, unfortunately, every part can sometimes fail. Probably, many car owners know firsthand about the problem of a lit check engine light (check engine light sensor). Naturally, any deviation from the norm slightly alarms a person, and therefore this article will discuss the causes and ways to eliminate this problem.

Typically, when the ignition is turned on, the engine warning light comes on. If there are no problems in the operation of the car, the light should go out within a few seconds after the engine is fully started. However, it also happens that the check engine light does not go out or lights up suddenly.

If the engine warning light sensor comes on, then for some cars this is a warning sign, and it is necessary to urgently find out the reasons for the appearance and take measures to eliminate them. This can be done by going to a car repair shop or diagnosing your car yourself and fixing the problem. However, it is better to do this if the driver understands technology and has experience in car repairs.

On the Lada Granta, the check engine light comes on when errors or malfunctions in the engine are detected.

Many modern cars have a complex mechanism, and the engine check can respond to engine speed, the composition of the working fluid, fuel consumption, and ignition. Therefore, it will not be possible to quickly name the cause of the failure, especially if you lack skills and experience.

Lambda probe

The oxygen sensor is part of the exhaust system. It checks how much oxygen is not burned in the engine cylinders. The lambda probe also monitors fuel consumption.

Various malfunctions of the named sensor do not allow the ECU to receive information from it. Sometimes this element provides incorrect information. Such breakdowns can increase or decrease fuel consumption and reduce engine power. Most modern cars have two to four such sensors.

Among the reasons for the failure of the described element is its contamination with waste oil or oil soot. This reduces the accuracy of collecting information to regulate the fuel mixture and determine optimal fuel consumption.

How to reset the on-board computer on a Priora? • You can't really argue with external factors, so the following may be reasonable recommendations.

Fuel filler cap

Most drivers, when an error occurs, always think about the existence of very serious problems. But few people think to check whether the fuel system is tight. But this same tightness can be easily broken by a gas tank cap that is not tightly closed. And this is a fairly common situation!

What does this have to do with engine error? The fact is that when the lid is not tightly closed, air passes into the system, which increases fuel consumption. Because of this, the diagnostic system generates an error.

Possible reasons for the check function to light up

The “CHECK” signal is located in the very center of the instrument cluster, where the driver can quickly pay attention to it.

Check engine light came on during hard acceleration

This function is responsible for the operation of the engine and if it signals, then there may be problems in the operation of this particular unit. Of course, this is scary for any motorist, because repairing the power unit is complex and expensive. But don’t immediately get scared and panic, the reason may be petty.

So, let’s look at what are the reasons why the “CHECK” function on the Lada Grant came on:

• If the indicator lights up when you start the engine, then don’t worry, everything works.
• If the “CHECK” lights up and signals for a long time, then, first of all, it is necessary to make a diagnosis, and only then worry.
• If there is a “CHECK” while driving, this may mean that there is insufficient oil level in the engine ( p0523 - error when the oil pressure sensor is faulty ).
• The “CHECK” function is on - it’s worth checking the engine for signs of depressurization or oil leakage.
• If the above reasons do not work, but the “CHECK” is lit, then this may be a signal that the spark plug has failed or low-quality fuel has been filled.

When the “CHECK” function lights up, it indicates that something is wrong with the engine and it is worth carrying out diagnostics before taking other actions.

Elimination methods

Let's consider some options for eliminating the causes of the “CHECK” function fire on the Lada Grant:

1. Bad fuel. The elimination method is quite simple - drain the low-quality fuel and fill in new one. Let the engine run a little and turn it off. If everything is normal, then upon startup, the signal will disappear. AvtoVAZ recommends refueling with 95 gasoline, but it often causes errors and complaints about its quality. What kind of gasoline do you fill up with, 92 or 95?
2. Spark plugs and high-voltage wires. Unscrew all spark plugs and check the gaps and the presence of a spark. Replace faulty spark plugs and wires.

The faults that you can fix yourself are indicated, but if nothing works, you should contact a car service.

Underwater rocks

If the “CHECK” light comes on on the Lada Grant, then do not panic. Often on cars the signal is supplied from a common ECU, which, like any computer, can malfunction. This may be caused by a short circuit or replacement of electrical circuit components. Therefore, errors occur in the electronic control unit, which can serve as a “CHECK” signal.

The ECU in Grant is not located very well, and if your check light came on during or after rain, then water could have gotten into it due to design features.

The ECU is located under the glove compartment

This problem can be treated quite simply. The ECU itself needs to be connected to a software laptop and errors in the system should be corrected or outdated firmware changed. It is best to entrust this operation to specialists who know how it is done.

Resetting an error without using an adapter (collective farm method)

If you are sure that the check engine light is “temporary”, that is, the quality of gasoline is poor, or the spark plug was faulty, which has already been replaced with a working one, then the check engine light can be reset manually without using an adapter; there are two ways.

1. To do this, disconnect the terminal for five minutes , the memory in the electronic engine control unit (ECU) will be reset, and the on-board computer readings will also be reset.
2. There is a second way, you just need to remove the cigarette lighter fuse ; Grant's design engineers installed an immobilizer on it.

Catalyst

This part makes exhaust gases cleaner. It converts carbon monoxide and other harmful substances into environmentally friendly compounds. If the catalyst is not working, the problem can be measured not only by the icon on the instrument panel, but also by a significant decrease in power.

The mass air flow sensor measures the amount of air needed to create the optimal fuel mixture. The sensor constantly communicates with the ECU. If this element is faulty, the level of carbon dioxide in the exhaust gases increases, the power of the power unit and the smoothness of the engine decrease. You can also observe weak acceleration dynamics.

Errors on the grant dashboard

The list of possible faults is long. So we've broken it down into three parts based on the original issues. These are the error codes that it produces:

Grant ECU: error codes

The largest group of faults . This includes data on internal combustion engine sensors. Code numbering from P0030 to P2501.

What do you need to know about the Check Engine Light?

Some drivers try to clear the engine error by disconnecting the battery. These manipulations really allow you to get rid of the problem. However, the lamp may light up again after a while. This means that no typical reason is suitable for this situation, and it turns out that it is necessary to perform a more in-depth diagnosis.

For this purpose, special software and hardware systems are used, which not only find any errors in the operation of the ECU and engine, but also know how to eliminate them. If the error was resolved during the tests, the lamp will go out. In some cases, it is necessary to drive the car for some time to reset the error. This may be due to the fact that the control unit needs time for in-depth testing and debugging of the operation of all car systems. If the lamp does not go out, you need to continue searching for the problem.

What does the Check Engine icon mean on the Lada Granta?

If the check light on the Grant 8 valves is on, first check the engine. When this is where the problem lies, unscheduled maintenance is performed. It happens that the motor is fine, but the signal is still there. In this case, you need to make sure that high-quality fuel is filled.

Then they test the ignition and the operation of the fuel supply system. Minor failures, such as failure of the cap that covers the gasoline tank, can be eliminated during a routine check or visual inspection. If the check on the Grant 16 valves is still on, and it is not clear why this is happening, a comprehensive diagnosis is needed. When the blinking goes away on its own, serious system malfunctions are gone.

There can be many reasons for a check mark blinking; to eliminate the problem, it is important to accurately determine the triggering factors.

Freeze frame: accurate diagnosis

This is a snapshot of the main parameters of the engine and transmission system at the time of the breakdown. So, not only the indicators themselves, but also the engine error can be stored in memory. A freeze frame can help figure out what happened in the car. This is a very useful option.

You can detect various malfunctions and quickly fix the problem. For example, if error P0116 was found in the ECU memory, then you need to look for coolant and air temperatures in the freeze frame. Let the coolant temperature be 40 degrees and the air temperature 84 degrees. This simply cannot be, and you should look for problems in the engine temperature sensor or in poor contact

How to reset a computer on Kalina?

If your car is equipped with sensors for the purity of process fluids (motor oil, fuel, etc.), then the indicator may light up if the corresponding indicators exceed the permissible limit. I read that with large minuses, if there is not a lot of gasoline in the tank, then gasoline vapors can crystallize and precipitate, gradually disabling the fuel system.

Independent in-depth diagnostics

Until recently, it was almost impossible for an ordinary car enthusiast to carry out independent diagnostics for a car - there was simply no available equipment. Yes, and before this was not particularly necessary - the engine error was deciphered by the way the indicator blinked.

Today, inexpensive and simple devices that operate via the OBD-II interface are offered for self-diagnosis. These devices allow the car owner not only to find operating errors in the ECU, but also to monitor various parameters.

You can purchase and install an on-board computer, or rather, just a console for it. Then you can find out the code of a particular malfunction without leaving the salon. The price of the issue is from 3,000 rubles, however, this is not an ideal solution. You can also purchase a wireless OBD-II adapter and decrypt codes directly from your smartphone. The cost of such a solution is from 1,000 rubles.

Where is the diagnostic connector located?

Since this interface is a standard, its location is also unchanged. It can be located in different places depending on the make and model, but no further than a meter from the driver. The standard configuration is 16 contacts in two rows.

Often, the diagnostic connector is located at the bottom of the dashboard in the driver's seat. On some models it may be hidden near the fuse panel or under the ashtray. For example, in a Volkswagen car, the mentioned connector can be found under the center console cover.

How to connect and use?

You need to connect the scanner in the following order:

A variety of software can be used to find and fix errors. You can find various programs online, both paid and free. For the first time, you can use free software that can read current data, find errors, and tell you how to reset the engine error.

How to decipher scanner error codes?

Without deciphering the codes, there is no point in diagnosing. That is why, in addition to selecting equipment and software, it is necessary to pay attention to this topic, especially if you do not want to pay specialists from the service station for the work. So, there are general principles that can help decipher this or that error. The software issues a code in the form of a letter and four numbers. The letters stand for:

• B – body;
• C – chassis;
• P - gearbox or engine;
• U – data exchange bus.

The first digit in the code is 0. This is the general code for this standard. The second and third are the year of production of the car. 3 – reserve digit. The second digit in the code is the type of problem, which will tell you how to remove the engine error:

• 1-2 – problems in the fuel system or in the air supply system;
• 3 – various problems in the car’s ignition system;
• 4 – additional control;
• 5 – idle;
• 6 – ECU circuits;
• 7-8 – transmission.

The fourth and fifth digits are the serial numbers of the errors. There is no point in listing all the error codes, because there are a lot of them. You can find out more information on the manufacturer's website. For foreign cars, the codes are mostly standard.

Types of analog panels

For the Granta FL model, 5 variations of instrument panels have been developed.

CAN is a high-speed data transmission network laid inside the machine. The time it takes for a signal to appear on the panel from the moment it occurs is 0.001 seconds. This speed allows the driver to receive information instantly. Moreover, this applies to all parameters: speed, oil and fuel systems, mileage tracking, operation of the air conditioning system, etc.

Diagnostic procedure: "Ford"

Let's look at the procedure for diagnosing some cars. In a Ford, the first thing you need to do is turn on the ignition. It is not at all necessary to start the engine. Next, on the dashboard you need to find the daily mileage reset button - you need to press and hold it.

Then, without releasing the button, the lock rotates to the second position. In this case, it is necessary to monitor when a message appears on the odometer screen indicating that the test has begun. At this point the button can be released.

This is how in a Ford car an engine error displayed on the dashboard will tell you where to look and where the fault lies.
