Priora connector

The main diagnostic connectors are OBD connectors. On earlier VAZ models, such as 2110, the OBD-1 connector was used. Currently, the most popular connector, which is used in all modern Lada models - OBD-2, has also been abandoned.

This diagnostic block in the Priora is located behind the glove box compartment; the scanner is connected to it.

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.

Diagnostics

Priora diagnostics can be carried out at any service station. This allows you to identify problems with the engine, namely the culprit of the problem. It will help save money, time and effort to find the cause yourself or at random.

Such engine scanning at a service station is carried out with an expensive and advanced scanner, which is quite expensive. Checking the Priora ECU for errors in a specialized service will cost from 1000 rubles and more.

1. Outputting and reading error/problem data from CU memory blocks;
2. Displaying actual values ​​of measured parameters;
3. Management and control of actuators;
4. Display of graphical information with values ​​during the check (graphs and tables);
5. Use of specialized ECU capabilities (depending on the manufacturer);
6. Testing and monitoring of electrical connection circuit components, correct installation of electrical circuit components (chips/sensors);
7. Regulatory (declared) data on controlled parameters;
8. Carrying out voltage measurements;
9. Carrying out resistance measurements;
10. Carrying out current measurements;
11. Using an oscilloscope to record the values ​​obtained during testing.
12. Definition of about 3000 error codes;
13. Engine speed - idle, operating code;
14. TOZH;
15. Fuel consumption;
16. Intake air temperature and air flow rate;
17. Absolute throttle position;
18. Oxygen sensor;
19. Fuel system and pressure indicators;
20. Read other data and faults.

A diagnostic device connected to the Lada control unit evaluates the accuracy and serviceability of the sensors. The result is a clear assessment of the technical condition, and the ability to carry out repairs in a short time with minimal financial costs.

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.

Adapter

On currently produced VAZ models, there is a high demand for adapters (level converters) of the KL series with a USB connector. They are designed for docking a laptop (or desktop personal computer) with channels “K” or “L” of the ECU (electronic control unit).

The adapter is used to diagnose vehicles and control their functions. Before starting work, you must install the appropriate diagnostic programs (“software”) and a driver for adapting the programs to your computer.

It is better to buy an adapter for diagnostics in the form of an already mounted unit with a USB port for a computer.

Adapter models:

Almost all adapters support domestic cars produced since 1998. The range of models is large. The choice depends only on your preferences in technology and income.

The cheapest adapter for VAZ is ELM327. The most commonly used universal adapter is BM9213.

ELM 327

Adapter design:

• printed circuit board (material: foil-coated fiberglass),
• OBD II standard port for connecting a USB cable inside the car,
• body (material - metal or plastic).

Diagnostic application

There are several really useful applications that can be used to perform high-quality car diagnostics.

OpenDiag Mobile

It is the main and most useful application for diagnosing domestic cars. This application is designed specifically for Russian-made cars.

Advantages and disadvantages

Pros:

• Decoding of all errors and a detailed description of the malfunction;
• Online engine monitoring;
• View misfires;
• Recording LOGs;
• Forced activation of fans and much more;

Minuses:

• Absence in the AppStore, that is, it is not suitable for iOS;
• Some ECUs are chargeable;

Car scanner ELM OBD2

Although this application was not tailored for domestic cars, it works very well with them. It is an alternative to open diagnostic for iOS.

Advantages and disadvantages

Pros:

• Free application;
• A large number of different functions;
• Online engine monitoring;

Minuses:

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.

An example of diagnostics using the ELM327 scanner

Below is an example of diagnosing a car with a scanner from AliExpress on version 1.5 using an Android phone and the OpenDiag application on a Lada Priora.

All manipulations with scanning the ECU must be carried out with the engine running or with the ignition on.

We connect the scanner to the OBD-2 connector and wait until the indicators blink.

Next, go to Settings/Bluetooth on your phone. There we find OBD II and pair it with it. When pairing, the device will ask for a password code - 1234 , this code is the same for all scanners.

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?

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.

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).

Errors in the idle system and ESC of Lada Priora

P0500 – a malfunction in the sensor that is responsible for speed. When the last digit is 6, the speed is low, and when 7 is high. At 11 the regulator is broken, and at 60 the voltage is low, and at code 62 it is too low. Code 63 numbers indicate high voltage. 0601 – checksum malfunction. Code 0627 indicates tears in the fuel pump cables. With code 0645, 46 and 47 - problems with the air conditioner.

This is the main list of problems and malfunctions that occur in the car. If you decipher them correctly, then it will be much easier to repair the car and correct Priora errors. But even with the most effective equipment, you need to remember that a good auto mechanic cannot be replaced by any testing device.

Do-it-yourself diagnostics

Various breakdowns of sensors and other devices can cause increased gasoline consumption, incorrect engine operation, and increased wear of car system components. Despite the presence of errors, the VAZ Priora will drive until the driver has to make expensive repairs because of them.

VAZ Priora car

So that the motorist does not suddenly have to face the need for repairs, a special controller is installed on the VAZ Priora, with the help of which the driver can diagnose breakdowns. This can be done either using special additional equipment or an on-board computer installed in the car.

In fact, to carry out diagnostics, the car owner will only need to press a few buttons and count combinations of faults.

For example, you do not have a special tester, so we will look at diagnosing the vehicle for errors using the on-board computer. The BC is built into the dashboard and can be used to read combinations of faults. To do this, you need to activate the auto test mode.

The arrows on the dashboard move to maximum values ​​when performing self-diagnosis of the vehicle

1. First, turn off the ignition. After this, hold down the daily mileage reset button and turn on the ignition. Please note: the button must be held down.
2. There is an LCD indicator on the vehicle's dashboard, keep an eye on it. When you turn on the ignition, all icons will begin to light up, and all arrows (speedometer, tachometer, antifreeze temperature sensor, gasoline level status) will begin to move to the maximum values ​​and back. That is, if all the arrows behave as described here, this means that the sensors and indicators are functioning correctly.
3. Now you need to find the button for switching BC functions - it is located on the right steering column switch. By clicking on it, the software version (1.0 and higher) will be displayed on the screen.
4. Click on this button again. Combinations of faults will begin to appear on the screen. If necessary, you can reset error data here. To do this, press and hold the daily mileage reset button for about three seconds.

Troubleshooting

Note! If you are unsure of your own abilities, the motorist is strongly recommended to seek help from a specialized workshop or a qualified technician.

If you have the necessary equipment, you can determine whether 8 or 16 valves are broken in a Lada Priora car yourself. Due to the simple design of the machine, repairs do not require the user to have in-depth knowledge of mechanics, electronics or other sciences.

Today I tested it, it works, the connection is stable. If there is an error, then the software writes the number and transcript.

To solve the issue, you need !

1. Smartphone, Tablet for Android v4,5,6.7 2. Bluetooth adapter ELM 327 bluetooth-elm327 />3. OpenDiag software

With the purchase of this adapter, there is no need to install such things as the State on-board computer. The adapter is in the glove compartment, the pipe is always with you!

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.

Problems with additional systems and ignition

If a spark does not occur in all cylinders or only in one of them, then a code from P0300 to P0304 may appear. If the detonation devices are broken, then the code is P0326. If the signal is weak in the same place, the code is P0327, and if the signal is too strong, the code ends with the number 28.

If there are problems with the crankshaft, code P0335, in this case: 0336 - the indicators are outside the limits; 0337 – short circuit; 0338 – network interruption. Errors P0342 - a weak signal is received from the phase sensor, and with P0343 - too strong. But if the number at the end is 46, then the data has gone far beyond the permissible limits. If there are problems with the coils and cylinders, then these are codes P0351-P0363.

Error p0422 indicates a breakdown in the neutralizer. If a situation occurs where “error 0422” appears on the display, this may indicate a decrease in the efficiency of the neutralizer below the permissible threshold, and with code 0441, the error indicates a problem with the air valves. With codes 0480 and 0481 there is a problem with the fan.

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.
