Diagnostic connector VAZ 2115 where is the photo

The VAZ 2114 diagnostic connector is required to connect the on-board computer. This device is in high demand among car enthusiasts, because it makes the operation of vehicles more convenient. There are many computers that will suit the VAZ. They can be connected to the car using this connector.

In most cases, there are instructions for using the device and connecting. But drivers often use used products that do not have the appropriate documentation. In this case, you will need information about where exactly the connector is located and how to install it.

Why is diagnostics of a VAZ car necessary?

A frequent case that worries a car enthusiast is the “check engine” signal, which notifies about a malfunction of the car system. This is usually a reason to visit a service station, but today we have the opportunity to identify the cause of the alarm ourselves; for this we will need to buy a diagnostic adapter. With its help, you can quite simply carry out diagnostic measures - identify malfunctions, determine malfunctions of your car, change settings, and obtain information from sensors. And all this with minimal financial investment.

Which adapter to choose for VAZ

Before you buy a scanner for diagnostics, you need to find out which control unit is installed on your vehicle. Most models are equipped with control units with a K-line for data exchange. Therefore, the best choice is a VAGCOM diagnostic cable or an improved version of the K-Line diagnostic adapter. These adapters are suitable for diagnosing VAZ vehicles and ensure correct coordination of the vehicle's diagnostic system and computer. Please note that you will be able to perform full computer diagnostics, just like specialists at a service station.

Where is the diagnostic connector located?

The typical location of the diagnostic connector on VAZ cars is in the passenger compartment under the dashboard. But at the same time, its location differs on different models:

On VAZ 21099i, VAZ 2108i - below the shelf, on the passenger side;

On VAZ 2115 – below the cigarette lighter;

VAZ 2112, VAZ 2111, VAZ 2110 – to the right of the steering column;

• Kalina - above the cigarette lighter;

• Priora - the connector is located behind the glove box.

Connector location and features

On VAZ 2114 and 2115 cars, where a Europanel is installed, the diagnostic connector (DR) is located on the central control panel under the cigarette lighter. It is closed by a decorative plug. To access the connector, just pry off the plug and it can be easily removed.

Location on VAZ 2114

VAZs can be equipped with a 12-pin rectangular connector of the old style OBD 1 (GM-12) or a 16-pin OBD-II connector in the form of a trapezoid USB-KKL. If the adapter is intended for OBD-II AR, you can buy an adapter.

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.

Elm327 for VAZ 2114: instructions for use

Using the example of a VAZ 2114 2012 ISO 14230-4 KWP (fast init, 10.4 kbaud) Gasoline Russia, we will demonstrate how the elm 327 diagnostic scanner with an OBD II Bluetooth connector works. As a rule, the device is supplied with a disk containing a special program in Russian for full diagnostics of the car.

Elm 327 Bluetooth operates on Android version no lower than 4.2 (there will be no connection on lower versions). Any device on such platforms is suitable for full scanning.

Before starting work, the user must install on a smartphone/tablet a program to interact with the auto scanner, which is necessarily included with the device. It is this program that will analyze the condition of the car, quickly finding sources of possible problems.

The process of scanning the car’s condition using ELM327 Bluetooth involves sequentially performing the following steps:

see also

1. The device is inserted into the connector (in the VAZ 2114 it is located at the bottom). After this, the light on the device should light up.
2. The car ignition is turned on.

On a mobile device (smartphone/tablet):

• Bluetooth turns on;
• in the pairing settings, enter the password “1234”;
• The previously installed diagnostic program is located and activated.

Next comes the connection

During the connection process, it is important that the typewriter on the screen of the mobile device (in the upper corner of the screen) stops blinking and lights up constantly.

The car starts. Any errors present will then be displayed as codes. All information about specific error codes can be easily found on the Internet, and then proceed to eliminate them. If you do not do this, but simply reset the errors, then the “CHEK” (signal of existing problems) will disappear for a while, but then light up again.

After a complete test of the car, you should remove the elm327 for the VAZ 2114 from the connector.

Using a car scanner, you can independently identify more than 3 thousand error codes, among which will be the results of research in the following areas:

1. Fuel system condition.
2. Fuel consumption.
3. Fuel pressure.
4. Fuel balancing (long term).
5. Short term fuel data.
6. Throttle valve position.
7. Engine speed in operating condition and at idle speed.
8. Coolant temperature.
9. Intake manifold pressure.
10. Air flow speed.
11. Air temperature at intake, etc.

These and other parameters are analyzed in detail by the program using information received from the Elm 327 auto scanner. The result of testing will be a detailed report displayed by the program on the screen of a smartphone/tablet. It will list all the error codes present in this vehicle.

5 months ago ELM capabilities: 1. What blocks can be read: engine block. 2. What is it for: saving money when contacting a service (the ability to not hang noodles on your ears and, in principle, determine whether you can solve the problem yourself), the ability to read and reset the error (so that the car behaves correctly) 3.

Popular software: Carscanner and Opendiag, Torque normal version. 4. Connection types: wi-fi, BT, USB. If mobile Internet is required at the time of scanning, mobile Internet will not work when wi-fi is turned on (take this point into account). For IOS only Wi-Fi, or on Bluetooth 4. 5.

There are elmki on an ARM chip, ICAR ones (they work faster and are more reliable). the name is VGATE ICAR, on the Pikov chip Viecar 6 will be more reliable. For which cars it is compatible, you can check on the website ROS. ELM representative. 7. Types of ELM with and without a button: there is no difference in the filling, only the presence of an on/off button. so as not to remove it from the slot every time. 8.

Is it necessary to remove the adapter from the socket, or can you travel with it all the time? We recommend removing it, because... a) extend the service life of the scanner, it will not burn out quickly. b) excess energy consumption. 9) Poorly compatible with Mikosov’s brains. (in this case, the lanyard will work, but only works with the laptop)

Feel free to ask the seller if it is compatible with your car. Do they provide a guarantee for ELM: basically no, because... service life directly depends on use. The Opcom scanner is perfect for Opels. If anyone already needs multi-brands for work: good copies of Delphi, close to the originals (aka Autocom). Compatible with various car brands

Error code: Kalina 2 obd connector – Property protection

Pay attention specifically to the board (it contains the main difference and capabilities), and the name Delphi or Autocom makes no difference, the filling is the same and the software is similar. There are both dual-board and single-board versions

Difference in price and capabilities (how many blocks it counts) For trucks, single-pay. Price lists for devices (with a normal board): double board about 2000 UAH Single board about 3000 UAH For those who need to get into all the blocks for their car, already look at Launches (the original costs space for all brands, but there are about 200 brands stitched), but they are not updated.

In principle, there is no need for updating there. Suitable for Android (it works crookedly with IOS, although it is stated that it should) About 11-12 GB of free space on the device is required For Vag group: Vasya Diagnostic (license), ideal option. Price tag is about 2700 UAH, with adapters for certain car brands about 3000 UAH For VAZ, ZAZ, GAZ a k-line adapter is suitable (works from a laptop) about 400-500 UAH

Elm 327 does not connect to the ECU (electronic control unit): what to do?

If the elm327 adapter does not connect to the VAZ 2114 ECU, then it is possible that you purchased version 2.1 or version 1.5, which was converted from 2.1. The fact is that such devices use a different version of the Bluetooth module, which supports only 2 protocols out of the available 6. In this case, the adapter connects to a smartphone/tablet, but when you try to connect to the car’s ECU, a message appears that the ECU is not responding.

If your adapter elm327 VAZ 2114 really belongs to version 1.5 and has all six protocols, then you can correct the work and adapt to the ECU commands by manually entering initialization lines.

Such attentive and responsible attitude towards the technical condition of your own car will be a guarantee of safety for you and your loved ones. Trips of any distance will no longer be a test of your own luck and will turn into comfortable trips that bring maximum pleasure.

It should be noted that such situations arise quite rarely. As a rule, a high-quality car scanner purchased from a reputable seller does not present the owner with any unpleasant surprises. The main thing is that during the process of purchasing/ordering a device, the make of the car, the year of its manufacture, etc. are taken into account. It is advisable to check with the seller how well the elm327 adapts and works on the VAZ 2114.

Useful video

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.

DIY diagnostics of VAZ 2114 and 2115. Using a laptop. Recommendations from the experts

Every driver has access to do-it-yourself diagnostics of VAZ 2114 and 2115. It's quite easy to learn. Moreover, such a skill may be needed at any time. Engine errors can occur regularly. This may be due, for example, to low-quality fuel. You need to make sure of this. At the same time, visiting the service for the purpose of diagnostics is expensive and time-consuming. In this regard, it is a good idea to learn how to diagnose problems and do it at any convenient time. This will also significantly speed up the elimination of identified faults. In any case, the ability to correctly and quickly diagnose your car is a very useful skill. Many drivers find this very difficult and do not even try to carry out such work on their own. But in reality, anyone can do this...

Of course, this article will contain general rules of action, but with the help of them you will be able to inspect the entire car.

Know-how of modern computer diagnostics

This is accessibility, the ability to diagnose the car yourself.

Currently, scanning for flaws in the functioning of a car can be easily done in a garage before a serious flight or simply an emergency stop on the side of the road. For example, if the “check engine” window lights up on the instrument panel.

Special equipment is not required. To identify the cause of the problem, only certain skills are required, as well as:

1. vehicle,
2. laptop,
3. adapter,
4. cable for connecting via a computer adapter to the vehicle controller.

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).

obd 2 pinout

Connection diagram of contact elements to the diagnostic block:

1. Backup contact. Depending on the manufacturer, any signal can be output to it. He is appointed by the car developer.
2. Pin K. Used to send various parameters to the control unit. In many cars it is designated as the J1850 tire.
3. A backup contact assigned by the vehicle manufacturer.
4. "Ground" of the diagnostic block connected to the vehicle body.
5. Ground of the diagnostic adapter signal.
6. Contact element for direct connection of the J2284 digital CAN interface.
7. Contact for connecting channel K in accordance with the international standard ISO 9141-2.
8. Reserve contact element, assigned by the vehicle manufacturer.
9. Spare contact.
10. Pin required for connection to J1850 class bus.
11. The purpose of this contact is determined by the machine manufacturer.
12. Appointed by the car developer.
13. Reserve pin assigned by the manufacturer.
14. Additional contact element for connecting the digital CAN interface J2284.
15. Pin for channel L, designed for connection in accordance with ISO 9141-2 standard.
16. A positive contact for connecting the car's electrical system voltage, rated for 12 volts.

As an example of a factory pinout of a block, you can use the Hyundai Sonata. In these models, the first pin of the connector is designed to receive signals from the anti-lock braking system control module. Pin number 13 is used to read impulses from the ECU (electronic control unit), as well as airbag controllers.

Pinout types may vary depending on the protocol class:

1. If the car uses the ISO9141-2 standard, then this protocol is activated by using pin 7. Pins numbered two and ten are not used and are inactive. To send information, contact elements 4, 5, 7 and 16 are used. Depending on the car, contact 15 can be used for this task.
2. If the car implements the SAE J1850 type VPW protocol, then the second, fourth, fifth and sixteenth pins are used in the connector. General Motors vehicles of European and American production are usually equipped with such pads.
3. It is possible to use the J1850 protocol in PWM mode. This application involves the additional use of the tenth pin. A similar type of connector is installed on Ford cars. Regardless of the type of output, the seventh pin is not used.

The MotorState channel spoke in detail about the pinout of OBD 2 diagnostic connectors for cars.

Programs for diagnosing VAZ cars

Due to the fact that there are many of them, let’s name a few of the most common and advanced:

1. KWR_D is one of the most reliable. Its advantage is that there are many useful adjustments. We list the main functions: - control of mechanisms (nozzles, coils, fans, etc.), - monitoring of vehicle parameters.
2. ICD 1.2.0.1 is the same (the program is free).
3. Diagnostic Tool vl.31.2 - control functions, there are adjustments.
4. AVTOVAZ NEW is the most modern option. The advantages are immobilizer control and adjustments.
5. Sens Diag - comprehensive diagnostics.
6. Motor tester is the same.
7. My Tester VAZ is the same with direct adaptation to VAZ models.

All of these programs work with Bosch blocks.

How to diagnose a VAZ car using a laptop:

1. Complete diagnostic equipment (laptop, connection cable, adapter),
2. Install the appropriate program and drivers on the laptop,
3. Using a cable, create a logistics chain “laptop - adapter - ECU - car computer”,
4. Setting up a connection between a laptop and a car computer,
5. Turning on the engine
6. Diagnostics.

Additional work

For more detailed diagnostics, inspect the car for body damage. Be sure to check the level of all technical fluids. Inspect the suspension and steering for any play. Compression must . Its values ​​should range from 9.5 to 11 atmospheres.

In this case, the readings of all cylinders should be approximately the same. The significant difference between them serves as a reason to take a closer look at the motor. You also need to check the condition of the battery . The voltage should be about 12.7 - 13.5 V (it varies). As an additional check, it would be useful to check the valve adjustments. Clamping one or more valves will result in an engine power error. To avoid digging up the injector in vain, it is better to check the condition of the valves in advance. Check the functionality of the spark plugs and high-voltage coils (high-voltage coils).

Diagnostic parameters for VAZ injection engines

What to pay attention to:

1. With the engine turned off, temperature sensors (data correctness); - throttle valve (presence of wear of the throttle mechanism; maximum wear - no more than 2%); — oxygen sensor (ADC MAF); presence of channel wear; maximum wear - no more than 1,035 V;
2. With the engine running and warmed up to normal (idling speed), the following parameters are checked (the value in each specific case depends on the engine model and ECU): - revolutions per minute; — air consumption for an 8 valve engine; — air consumption for a 16 valve engine; — injection time; if necessary, injection correction; — correction factor (%); — multiplicative component of correction; — additive component of correction; — cyclic air consumption (mg/stroke) for an 8-valve engine and for a 16-valve engine.
3. Screenshots of engine diagnostics on the monitor (depending on the ECU model using the example of a VAZ 2107) - ECU “January 5” - ECU M73

Self-diagnosis codes

When performing diagnostics, it is necessary to take into account that the number on the screen may indicate two summed errors. For example, 9 indicates the presence of two faults - numbered 1 and 8.

An example of error 14 appearing on the panel

Table of decoding codes for flashes calculated during diagnostics.

The data obtained allows you to quickly find the faulty element and eliminate the cause of the error.

The video from the Garage channel shows diagnostics on a VAZ 2115 using a scanner and laptop.

Objective indicators

Factors that determine the correctness of the data:

• car (engine) model,
• laptop (scanner) and adapter model,
• engine temperature,
• ambient temperature,
• operator qualification.

Thus, it is clear that the conclusions when diagnosing a particular car may not always be completely adequate to the current technical situation.

Although you can get an idea of ​​the malfunction and the cost of repairs.
