DIY Priora engine diagnostics 16 valves

Priora error codes: complete vehicle diagnostics

Their main problem is that if some sensors are turned off, the car will not disrupt its operation and can continue to move unhindered. However, the breakdown itself can be detected much later, when the negative consequences of disconnecting the sensors become apparent.

Depending on which sensor fails, fuel consumption may increase sharply, and some malfunctions in the operation of the car’s engine may also occur. In addition, a common “symptom” of sensor disconnection can be accelerated wear and tear of some elements in the car.

In order to check for certain errors on the Priora, you can use a special controller, which is built into the car specifically for this purpose. Thanks to this controller, you don't have to go into the engine compartment with a multimeter to look and identify the problem.

This controller is connected to a special tester, which is connected by manufacturers to the on-board computer. It won’t take much time to perform a full check of the car for any malfunctions in the operation of systems and sensors. You can start the process by pressing two buttons, and then all that remains is to correctly decipher the error codes.

Diagnostics with ELM-327 scanner

Thanks to Chinese engineers, car diagnostics have become much easier and cheaper. Not long ago, a universal internal combustion engine scanner appeared on Chinese websites, which is suitable for almost all cars with OBD-2 connectors.

The ELM 327 scanner on the AliExpress website costs from 5 to 10 dollars, depending on the version.

This gadget is divided into two types and you should pay special attention to this when purchasing. ELM 327 works with our domestic cars only on version 1.5. Therefore, you need to purchase an ELM-327 v1.5 scanner. If you purchase version 2.1, then work with domestic cars is not guaranteed.

It should also be noted that this scanner only works in conjunction with a smartphone. If you have an Android smartphone, then you just need to buy a scanner with Bluetooth only.

If your smartphone is based on iOS, then you need to purchase a scanner with a Wi-Fi module, since Apple smartphones do not allow connecting third-party devices via Bluetooth.

Malfunctions and repairs of the Priora 21126 engine

The 21126 engine is a continuation of the VAZ 21124 ten-wheel drive engine, but with a 39% lighter ShPG produced by Federal Mogul, the holes for the valves have become smaller, and a different timing belt with an automatic tensioner, thanks to which the problem of tightening the belt on the 124 block has been solved. The Priora engine block itself has also undergone minor changes, such as better surface treatment, and cylinder honing is now carried out in accordance with the more stringent requirements of Federal Mogul. On the same block above the clutch housing there is a place with the Priora engine number; to see it, you need to remove the air filter and arm yourself with a small mirror. Engine VAZ 21126 1.6 l. injection in-line 4-cylinder with overhead camshafts, the gas distribution mechanism is belt driven. The service life of the 21126 Priora engine, according to the manufacturer’s data, is 200 thousand km, how long does the engine run in practice... depending on your luck, on average this is approximately the case. In addition, there is a lightweight version of this engine - Kalina engine 1.4 VAZ 11194, as well as a sports forced version - VAZ0 hp engine, an article about it is HERE. Among the disadvantages of this power unit, it is worth noting unstable operation, loss of power, timing belt. The reasons for unstable operation and refusal to start may be problems with fuel pressure, timing faults, faulty sensors, air leaks through hoses, or a malfunction of the throttle valve. Loss of power may be due to low compression in the cylinders due to a burnt-out gasket, wear of the cylinders, piston rings, or burnt-out pistons. A significant drawback is that the Priora 21126 engine bends the valves. The solution to the problem is to replace the pistons with plugless ones. However, the Priora engine is currently one of the most advanced domestic engines, perhaps the reliability is worse than that of the 124th, but the engine is also very good and powerful enough for comfortable movement in the city. In 2013, a modernized version of this engine was released, the marking of the new VAZ 21127 Priora engine, an article about it is HERE.

The process of diagnosing a car using a tester or a connected computer

Much more accurate and reliable data when checking a car for malfunctions can be obtained if you use separately connected equipment. But the introduction of such tools and devices gives encrypted readings, therefore, in order to correctly understand and find all the faults in the car, you need to decrypt the data received from diagnostic devices. Of course, manufacturers could have done things easier for Russian-speaking car enthusiasts. It would be possible to write “replace the canister valve” on the device screen after diagnostics, but instead, only a code in the form of p0441 can be found on the display, and code p0130 will appear only due to problems with the oxygen sensor.

But the problem is that Lada Priora is produced not only for the domestic market, it is also produced for sale in other countries. Therefore, such a classification of automobile problems and their code on the testing device was created.

It is easier to enter only a certain number of universal codes into the program than to enter your own language data for each national market . As a result, you can look at a specific code on the display and easily determine the essence of the problem in the car using a list that lists all encrypted codes. A special code is used to indicate error codes on the Lada Priora car. This cipher includes:

• letter fault code;
• digital code for the location of a malfunction in the vehicle design.

On the Lada Priora, all gap codes in the vehicle's operation will have five digits. Here is a complete list of Priora designations. The first character of the code will be a Latin letter. The letter “P” indicates problems with the engine, or more precisely with its electronic system. The letter “B” indicates problems with the interior electronics.

The letter “C” is present on the screen only if there are failures in the electronic system of the vehicle chassis. If combined errors occur in several operating systems of the vehicle, the letter “U” will appear on the display. The letter designation is followed by a number.

The zero indicator is indicated by the OBD-2 code. Numbers 1 and 2 show the company code, and the third digit is responsible for the backup code. The subsequent set of numbers conditionally shows the place where errors were detected during diagnostics. A zero code indicates the exhaust system. Number 1 indicates the fuel system, number 2 indicates the air supply system.

If there is a malfunction in the ignition, then the number 3 will appear. If there are problems with additional control, the number 4 will appear. If there are malfunctions in the idle speed, then the number 5 is responsible for this, and if there are problems in the ECU, the number 6 will appear. Numbers 7 and 8 are associated with the transmission In the general code, the very last two digits indicate the error number in the operation.

In this video, the author talks about the power failure error on the ECU of a VAZ Priora car.

Error codes - malfunctions of the electric power steering ESD on the Lada Priora VAZ 2170 2171 2172 (Lada Priora)

The first character means the following:

• B – code is intended for body systems, i.e. AIRbags, central locking, electric windows
• C - code is intended for the chassis system, namely the Priora chassis
• P - code is intended for the engine and its operation and / or automatic gearbox (automatic transmission);
• U - code is intended for interaction between electronic units of Lada Priora

Features of diagnosing VAZ and LADA cars using auto scanners

Reading time

Difficulty of the material:

Most modern Russian cars of the VAZ and LADA family are equipped with an electronic control unit, as well as an on-board computer. Thanks to such electronics, the use of diagnostic equipment is becoming increasingly important.

The presence of all kinds of sensors on important components (engine, electrical, gearbox) allows you to monitor parameters, as well as accurately determine the type of malfunction. All information read by such sensors is sent to the ECU, then the data is converted into numbers using standardized protocols and transmitted to diagnostic equipment via the OBD2 connector. Then, using the software, the parameters and values ​​of the sensors are displayed on the external display.

The OBD2 diagnostic adapter reads and deletes errors , and depending on the capabilities and cost, such a car scanner can solve other problems, including chip tuning.

In this article we will consider and select suitable scanners for diagnosing VAZ cars, as well as programs for them. In addition, we will familiarize ourselves with the theory and provide recommendations for performing independent self-diagnosis.

Regularity of auto diagnostics

It is recommended to periodically, but at least once a quarter, carry out computer diagnostics of your car.

Which computer can be used for diagnostics?

The diagnostic software does not require PC resources; for this reason, you can use any computer with an operating system no lower than Windows XP. It is very convenient to use a laptop or netbook for diagnostics, since the cable length is limited.

A scanner for a VAZ is as necessary a tool in a car enthusiast’s arsenal as a regular wrench. The advantages of using it are obvious, you can quickly assess the condition of your car’s systems, identify the cause of the malfunction, many of them can be eliminated yourself without contacting a service station. It is also beneficial economically. The price of a diagnostic k-line adapter is no more than the cost of a one-time visit to a service center or service station.

You have set yourself the task of learning how to perform diagnostics and gaining access to activating hidden functions on a Ford car, and reducing the cost of visiting a service station. For this, today you have every opportunity. Of course, this will require some preparation.

Diagnostics of VAZ (LADA) cars

Is it necessary to devote energy to finding electrical problems in car services, order a tow truck, plus an endless wait for diagnostics at a service station. In fact, we detect breakdowns in the electrical equipment of a VAZ car right at their location. This greatly reduces the time needed to repair faults. Diagnostics of electrical equipment of LADA passenger cars is the defining direction of our technical assistance service! In 90% of cases, we identify breakdowns and glitches of the car right on the highway!

Engine tuning Priora 21126 1.6 16V

Chip tuning of the Priora engine

For fun, you can play with the sports firmware, but there will be no obvious improvement; see how to properly increase the power below.

Priora engine tuning for the city

There are legends that the Priora’s engine produces 105, 110 and even 120 hp, and the power was underestimated to reduce taxes, various measurements were even taken in which the car produced similar power... what everyone decides to believe, let’s focus on the indicators declared by the manufacturer. So, how to increase the power of a Priora engine, how to charge it without resorting to anything special, for a small increase you need to let the engine breathe freely. We install a receiver, a 4-2-1 exhaust, a 54-56 mm throttle body, and we get about 120 hp, which is quite good for the city. Boosting the Priora engine will not be complete without sports camshafts, for example, STI-3 camshafts with the configuration described above will provide about 140 hp. and it will be fast, an excellent city motor. The refinement of the Priora engine goes further, sawn cylinder head, Stolnikov 9.15 316 shafts, light valves, 440cc injectors and your car easily produces more than 150-160 hp.

Compressor for Priora

An alternative method of obtaining such power is to install a compressor, for example, the most popular option is an Auto Turbo kit based on PK-23-1, this compressor is easily installed on a 16-valve Priora engine, but with a lower compression ratio. Then there are 3 options: 1. The most popular, lower the coolant gasket with a gasket from a twelve-wheeler, install this compressor, exhaust on 51 pipes, Bosch 107 injectors, install it and go to the track to watch the car go down. But the car doesn’t run very well... then running to sell the compressor, writing that the Autoturbo doesn’t work and all that... is not our option. 2. We lower the coolant by installing a thick cylinder head gasket from 2112, for a St. Petersburg supercharger at a pressure of 0.5 bar this will be enough, we select the optimal narrow-phase shafts (Nuzhdin 8.8 or similar), 51 exhaust pipes, Volga BOSCH 107 injectors, a receiver and a standard throttle body. To fully push the configuration, we give the cylinder head to cut the channels, install larger lightweight valves, this is not expensive and will provide additional power throughout the entire range. This whole thing needs to be configured online! We’ll get an excellent motor with a power of more than 150-160 hp that can perform in any (!) range. 3. We lower the coolant by replacing the piston with a tuning one for the turbo, you can put a proven Nivov piston with a puddle under the turbo on 2110 connecting rods, on such a config you can put a more efficient compressor, a Mercedes one for example, blowing 1-1.5 bar with a power of well over 200+ liters .With. and act like the devil! ) The advantage of the config is the ability to install a turbine on it in the future and blow out at least all 300+ hp. if the piston doesn't go to hell))

The process of diagnosing a Lada Priora car using an on-board computer

First of all, you need to know how to reset the parameters using the button to reset all daily mileage indicators. It is located on the instrument panel. You must press this button and, while continuing to hold it, you must simultaneously turn on the ignition using the key. Using these steps, you will be able to see all the error codes that have occurred and are available. Before displaying a list of error codes, the vehicle's autonomous self-diagnosis is enabled.

At this time, at the beginning of the diagnostic process, all arrows on sensors and instruments should show a jump from the minimum to the maximum indicator, at the same time at this moment all the necessary indicators and errors for checking the car should be shown on the liquid crystal display.

If at this moment any arrow does not show the correct movement or any position on the display does not appear, then you need to check the sensors and systems of the car for errors. Also, do not forget to check the display itself for faults, because A situation is possible when the car is working correctly, but errors are shown on the display solely due to the separation of any contacts.

Now, in the same mode of self-checking the car, you need to double-click any button that is responsible for switching the operating mode of the on-board computer. After these steps, certain numbers should appear on the on-board computer’s LCD screen. These are the Lada Priora error codes.

Error code

Decoding

Video diagnostics with ELM scanner

Like any modern car, the Lada Priora is equipped with dozens of various sensors, the functioning of which determines the condition of the main vehicle systems. Diagnostics of the machine for errors allows you to detect all sensor faults in order to eliminate breakdowns. Now you will learn how Priora error codes are deciphered and how to independently diagnose the on-board computer (hereinafter referred to as BC).

How is self-diagnosis performed?

We have sorted out the main errors on the Priora, now it’s worth finding out how self-diagnosis is performed. The VAZ 2170 with 16 valves has a special controller with which diagnostics are performed. If you have an on-board computer installed, then diagnostics are performed on it. There is also special equipment that allows for a more in-depth check of Priora 16 class systems.

Since most Priora 16 cars already have an on-board computer, we will consider the option without the use of special devices. Diagnostics begins with activation of the test mode. The work proceeds according to the following scheme:

1. Turn off the ignition. Now we hold down the daily mileage reset button, without releasing the button, we start the ignition of the Priora 16 cl;
2. On the instrument panel you will see a display with an indication. After turning on the ignition, all components of the instrument panel will light up. The needles of the temperature, speedometer, tachometer and other instruments will begin to move to the maximum level and back. This behavior indicates that self-diagnosis has begun;
3. Let's move on to the right steering wheel switch. Here you will find a button for switching the on-board computer settings. Click on it, a message with the software version will appear on the instrument panel screen;
4. The instrument panel error diagnosis will begin if you press this key again. Various codes will appear on the display, which you can decipher in the table below;
5. When the diagnostics are complete, you can reset the error data. Press and hold the daily mileage reset button for about 5 seconds.

How to fix the problem

There are several possible ways to resolve this issue. If one solution does not suit you, move on to the next one. We will also look at what to do if none of the options for eliminating error 4 helps.

Method No. 1 (Software update)

Trying to find out what the essence of the problem might be, many initially undertake to analyze the correct operation of the receiver and its unique ID (as a rule, it is already present on the access card, and if there is no smart card, it is integrated into the system itself). Here it becomes clear that the receiver is not able to recognize its own ID number, which, in turn, makes subsequent decoding of the channel impossible. Accordingly, if error number 4 appears, then you should understand the features of ID recovery.

1. If error 4 appears on tricolor TV, you need to go to channel 333. This channel is specially designed for performing service actions. It is after the transition to it that the procedure for updating the standard software is carried out.
2. Then check for updates. The receiver will do this on its own. When a new software version is detected, it will prompt the user to confirm the installation. After completing this action, error 4 tricolor should disappear.

What to do next? After the receiver accepts consent, it will initially carry out the installation from the satellite, and then, after reaching the 50% mark on the progress scale, it will begin installing the downloaded files into the device’s memory. This will continue until the progress bar is filled to 100 percent.

Note! If you are connected to a satellite and you have approved the installation of the updated version, do not turn off the receiver under any circumstances! Otherwise, you will not be able to completely fix the problem. In some cases, the receiver no longer displays channels due to insufficient files in the software package or due to their corruption

After all the necessary files have been downloaded and installed, the receiver will reboot itself for the updated files to take effect. After a reboot, the system should completely resolve the problem.

In the case of some models, installation of a software update for the module is additionally required. Remember that its update occurs immediately after the main firmware is loaded into the system. The module updates much faster. Mandatory installation of these files is not always required - much depends on the behavior of the system after the main firmware update is completed. If error 4 disappears, we don’t touch anything else. When saving it, we try to additionally update the module.

Important! Sometimes a software update may not help, since there is a USB flash drive in the slot. Remove it and reboot the receiver, it should help

Method number 2 (Reset settings)

Sometimes eliminating the fourth error requires resetting the receiver to factory settings and searching for channels again. This is done very simply:

1. Press the "Menu" button on your receiver's remote control.
2. Select "Settings".
3. Then scroll to the very end to the “About the receiver” section, “Reset settings”.

After you reset to standard settings, search for Tricolor TV channels again, and in order to watch channels with a broadcast shift relative to Moscow of +2 (+3) hours, select the “Ural” region.

Method number 3 (Contact support)

If the previous two methods of solving the problem did not help you, then you can contact Tricolor technical support. But before you call, collect the following information:

• ID number of the smart card;
• The number of your agreement with the Tricolor company;

Programs and applications used

Software that can be used for diagnostics is widely available. The portable diagnostic device Scan Tool Pro or any other OBD2 adapter without its own external environment is capable of working both through a smartphone (Anroid, iOS) and through a laptop running Windows OS.

Common and popular programs for diagnosing VAZ and GAZ are currently:

• OpenDiagPro. Designed for cars with an injector. It monitors not only all the main digital and graphic parameters of the power unit, but also indicates ECU errors.

More than 100 supported car brands and maximum access to car electronics. The most expensive and presented options.

VAG adapter (VAG-COM 409.1)

VAG diagnostic cable K-line (VAG-COM 409.1). The adapter is made on an FTDI chip and is well compatible with the January, MIKAS and other ECUs installed on domestic cars, including GAZ. It is not so convenient to connect wiring to it (there are no clamps). It is more often used for diagnosing cars produced before 2006.

Coolant temperature sensor - removal, check, installation

To complete the work you will need:

— multimeter (in voltmeter mode, ohmmeter with a measurement limit from 100 Ohm to YukOhm);

— thermometer (with a change limit of at least 100 °C);

- a small heat-resistant container with a volume of about 0.5 liters for water;

- about 0.3 liters of water, heated to boiling temperature.

The thermometer can be replaced with a digital multimeter with thermometer mode.

Removal and inspection

1. Drain the coolant.

2. Remove the air filter housing.

3. Release the clamp of the wiring harness block and disconnect the block from the sensor.

4. Connect the negative probe of the engine voltage.

5. Turning on the ignition, use a voltmeter to measure the voltage at terminal A of the wiring harness block (the terminal designations are marked on the wiring harness block).

Comment

The voltage at the terminal must be at least 12 V. If the voltage does not flow to the block or it is less than 12 V, it means that the battery is discharged, the power circuit is faulty, or the ECU is faulty.

Warning!

When the voltage measurement is complete, turn off the ignition.

6. Using a 19 mm spanner, unscrew the temperature sensor and remove it from the thermostat housing. The connection between the sensor and the thermostat is sealed with a copper washer.

7. Connect an ohmmeter to the sensor terminals.

8. Fill the container with boiling water, immerse the working part of the sensor in water and record the readings of the device at a temperature of about 100 °C. As the water cools, we measure the resistance of the sensor at temperatures of 90, 80, 70, 60, 50, 45, 40, 35, 30, 25 and 20 °C.

If conditions permit, readings can be taken at a lower temperature. The resistance of a working sensor should be close to the data specified in Table 9.2.3.

We replace the faulty sensor.

Installation

1. Install the sensor in reverse order.

2. Fill the engine cooling system with liquid.

3. Start the engine and make sure there are no coolant leaks from under the sensor. If necessary, tighten the sensor into the thermostat housing.

Recommendation

If the leak cannot be eliminated in this way, you should reinstall the sensor by applying a heat-resistant sealant to its threaded part, or replace the copper washer.

ELM327 buy.

As you can see, by observing even a minimal number of parameters, you can form an opinion about the degree of wear of the engine and related systems. If you want to be sure of the accuracy of the readings transmitted to you by the adapter, I recommend that you order the ELM327 from me. I found a high-quality supplier of multi-brand scanner data in China, and regularly monitor the quality of each batch and each adapter that comes to me. If you are interested in buying an ELM327 or you require advice in the selection of any diagnostic equipment and multi-brand scanners, call +7 (977) 469 50 92

Air and fuel system problem codes

P0030 means that the sensor cable, which is responsible for heating the oxygen, has broken. The break is located before the exhaust gas neutralization system. If the cable of the same sensor is shorted to ground, then code P0031 occurs. If the circuit after the neutralizer is broken, the number 6 will appear at the end of the code. Code P0112 is a weak signal from the sensor that is responsible for the air temperature; if there is a strong signal, then code P0113 appears.

If there are problems with a weak throttle signal, then the code P0122 appears, and a strong one - P0123. If there is a problem with the oxygen device, then error P 0130 appears. With P0133, the response to the mixture comes slowly; if error P0134 occurs, the device does not work.

If there is a lot of air in the fuel, then the code is 0171, and if it is 72, there is a lot of gasoline in the mixture. Code P0201-P0204 indicates damage to the injectors and their cables. If there is a code 0217, then the engine is heating up; if it is 0230, there is a malfunction in the fuel pump. With codes from P0261 to P0272, problems need to be looked for in the injectors.

Error code: obd2 adapter nissan on AliExpress - buy online at a good price

How to use

Before purchasing an adapter, make sure it is compatible with your car. After purchasing the adapter, it is important to correctly connect the scanner to the connector. As a rule, the OBD 2 connector is located in the passenger compartment under the dashboard. Models before 2006 usually have a 12 pin connector (GM), and to connect the scanner you will need a 16 pin adapter.

Information on the location of the connectors is presented in the table and photo below.

Location of diagnostic connectors and recommended auto scanners:

Diagnostic modes, OBD protocols for Lada cars

The adapter's task is reduced to decoding the incoming stream of data packets and converting them into a form accessible to external software. ELM327 works according to the protocol principle used in injection-type cars. The device receives information from the ECU data bus, processes it and sends it to a PC or smartphone.

Data exchange is carried out through several types of protocols:

Lada cars with electronically controlled internal combustion engines use several protocols:

The fastest option is the CAN bus. The system can operate in duplex mode, which expands the functionality of the on-board electronics. However, we note: each protocol has its own set of diagnostic modes. The most extensive service is offered by the latest generations of tires. For Lada, the standard set of modes is:

It is possible to adjust the characteristics of the lambda probe for individual ECU modules and firmware.

Important:

Some ECUs do not support the full set of functions without the use of a dealer scanner.

Select the car model and year of manufacture to determine which diagnostic modes your car supports through the ELM327 adapter, as well as what protocol the OBD2 port is based on. The data is presented for the following Lada models and their modifications: Granta, Kalina, Largus, Niva, Priora, VAZ 2107, Vesta, XRAY and others.

Useful video

You can learn more about how the scanner works in the video below:

In conclusion, it should be noted that using elm327 for the VAZ 2114 you can significantly save on car diagnostics and fix problems immediately after they appear (either on your own or at specialized service stations).

Computer diagnostics is a complex process. Even now, many people prefer to trust it exclusively to specialized service stations with appropriate scanning equipment.

Autonomous scanners allow you to identify all faults in the electronic and mechanical systems of a car quickly and completely.

The problem is the cost of the service. It is high and not accessible to everyone. Not even all auto repair shops provided such a service. Repairs, therefore, were most often carried out the old fashioned way - using the “scientific poke” method.

Decoding codes

Well, if you succeed in checking your car for faults, then you need to decipher the combinations of errors, otherwise why do you need diagnostics at all?

Self-diagnosis

Let's look at the decoding of combinations of faults that you can read when checking the Lada Priora yourself.

The arrows on the dashboard move to maximum values ​​when performing self-diagnosis of the vehicle, and all icons on the panel are lit. Please note: if the button for switching functions of the on-board computer is not pressed for more than 10 seconds, the dashboard will return to the operating state.

Failures in the ignition system

If you were unable to check your VAZ Priora yourself, you can do this using a special tester. In this case, the error code will be a combination of a letter and four numbers:

• P – means a breakdown in the operation of the electronic systems of the internal combustion engine;
• C – malfunction of the chassis;
• B – breakdown in the electronics of the car interior;
• U – indicates an error in the joint operation of different systems;
• the number 0 indicates the OBD-2 code;
• 1 and 2 – enterprise code;
• 3 – reserve code.

Fuel and air system error codes

Air supply

Normal air supply is the key to the formation of an air-fuel mixture and a normal combustion process. Thus, a malfunction of one or more air supply elements can lead to the engine starting to choke. These include the air filter and throttle valve.

Contamination of air elements is the reason why a car stalls..

The air filter element must be changed every 20,000 km, since after this it becomes clogged and becomes unusable.

But it is necessary to monitor the condition of the throttle valve, since it is unknown when it will become clogged and begin to cause problems. Typically, motorists clean this unit themselves, using special products or a carburetor cleaner.

Location

Often faced with a problem where the diagnostic connector is located. In each car they are installed differently, taking into account the specifics of the entire structure. As for Prior, everything here is done quite cleverly. If you don't know the exact location, it will be difficult to find.

Car manufacturers have placed a diagnostic connector in the glove box. You can find it on the passenger side in the interior. Simply put, look in the glove compartment. If you contact service centers, specialists will immediately find the required design. Beginners need to be more vigilant in this matter.

It is best to work according to already compiled instructions. Let's take a closer look at the process:

1. We completely open the glove box and clear it of foreign objects to make it easier to work.
2. The glove compartment should hang on plastic guides on each side.
3. We press on the side plates so that the small door opens further. This will make it easier to work and find the Priora diagnostic connector.
4. We pull out the tabs on the side and completely remove the glove box from the latches.
5. Provides access to the input plug for diagnostics. Now he is free and ready to go.

Access to the device is open. The following operations directly depend on the purpose of “opening” your car. More often they get to the connector to reconnect it or check the correct signals from the ECU. This way his work will be adjusted and will not create problems or unforeseen situations.

Hello. The Priora won't start. The starter turns. Is it possible to read errors using elm327 only when the ignition is on?

no only with it on

I understand that you have it constantly connected?! It just sticks out there in the plug, but the glove compartment closes properly?

why constantly, no, when there is a need then I connect

I practiced on three Open Diagram machines today! Showed only one truth! At four stationary speed the speed showed 67 km/h, the mains voltage was 7 volts. On the Priora the injection time was 78 ms. Does anyone know what is the reason for the incorrect readings?

Question for software developers. Make screenshots of the survey in OpenDiag too. THE RESULTS ARE MANDATORY FOR PUBLIC VIEW.

Where's the fuel consumption?

He exists, he cannot but exist!

Average? Or current

Install and see everything!

So I’m wondering if it’s worth it) otherwise when something is not on the screen you remember the old

The best advice is to try it yourself and post your results!

Hello, is it possible to use opendiag to make all doors open at once using the remote control?)

Will it work on Android?

Avtolubitel01

Hello, is it possible to use opendiag to make all doors open at once using the remote control?)

But it doesn’t work with the standard key, or what? it seems simple there.

I have a switchgear))) only for diagnostics)) I went to different specialists twice, they said the comfort unit is being repaired)) it does not record the ban on separate door unlocking))

I also bought a 327 adapter. I tried a bunch of programs for Android and couldn’t find one that worked properly. And I think using a mobile phone as a BC is tantamount to feeding a pig pineapples) And BC is still more convenient than an adapter-phone bundle. By the way, for a neighbor on a grant, plugging the adapter into the connector turns off the electric power steering.

ABS fault detection

You can find out about problems with the ABS by looking at the indicator light on the instrument panel. If it lights up for no reason or does not go out after the required period of time, you need to go to a service station and undergo computer diagnostics. Modern Priora ECUs have a diagnostic connector through which you can easily connect a portable scanner or a stationary motor tester.

All ABS electronics are connected to the mechanical part of the car, so only an experienced diagnostic technician can accurately determine the error that the system produces. ABS error codes start with 0035 and end with 0800. In order to deal with them correctly and determine the reason for the light bulb to light up, you need to have a table of error decoding on hand or resort to qualified help.
