ELM327 is one of the latest OBD developments. This scanner is used to check cars using a computer. The key advantage is that the device supports all known OBD protocols and interacts with many diagnostic programs. A USB cable is used to connect the device to a computer.

ELM327

The software for the ELM327 is mostly free, although some software is available only for a fee.

The adapter can work on computers with different OS. Namely:

• DOS;
• Windows;
• MacOS;
• Linux;
• PalmOS;

The full capabilities of the scanner can only be fully realized through properly selected software. For self-diagnosis, software for scanning the transmission and engine is available free of charge. Commercial versions of the programs allow you to additionally check other components of the car.

Key Features

Let's take a look at the capabilities that the ELM327 chip provides:

• Reads error codes and vehicle malfunctions;
• Displays codes and their descriptions;
• Exports data for printing, if necessary;
• Removes error codes;
• Displays data in metric and US measurement systems;
• Records, saves data, builds graphs;
• It has an acceleration counter from 0 to 100 km/h, which allows diagnostics on the go.

Many vehicle operating parameters must be checked while driving.

Not all adapters are suitable for this, so it is important to choose equipment that meets your requirements

What is ELM327

ELM327 is a microcontroller (chip/chip) that converts OBD protocols used in vehicle diagnostic buses into the RS-232 protocol.

As it happens, to reduce prices, Chinese manufacturers began to simplify car scanners and replace the “native” ELM327 controllers. The main task of clones is to execute OBD AT commands.

This has led to applications configured for standard protocols implemented in the ELM327 not working as intended (but working). For example, instead of PIC18F25K80 (replacement for ELM327), such auto scanners use the STM32F042 CAN controller

It's all about the OBD-II PID

Diagnostic connector for Lada Granta

The diagnostic connector of the Lada Granta car is designed according to the OBD-2 standard. On the Lada Grant, the diagnostic connector allows you to read almost all the information about the composition of the mixture and other data stored in the car controller. This is the operating mode of the fuel correction, the temperature of the coolant and intake air, and other data. The connector has 16 contacts and is located in the passenger compartment, to the left of the glove box, at the passenger’s feet, next to the ventilation deflector.

The arrow in the photo indicates the location of the diagnostic connector. It’s not that difficult to remove and install the Diagnostic Link Connector yourself. To remove the ECU yourself, disconnect the negative cable of the on-board battery and remove the screw securing the floor covering. Next, you need to peel back the upholstery and soundproofing coating to directly see the block itself, secured with 3 nuts.

Determining and decoding errors on the VAZ 2114

Self-diagnosis of a car allows you to identify faults, but some of them are rarely identified. An odometer is used for diagnostics.

Self-diagnosis of VAZ 2114

The sequence of actions is as follows:

1. Press and hold the odometer button and turn the ignition key to the first position.
2. Release the odometer button and press briefly again. As a result, the firmware version will be displayed.
3. Now, to see the error codes, you need to press and release the odometer button again.

Error codes are in the form of numbers from 1 to 9 and two-digit numbers, unlike those displayed by the on-board computer. Thus, you can use the odometer to identify some car faults. The most common errors are shown in the table below.

Error codes for VAZ 2114 injector 8 valves: table

Diagnosis of faults using special equipment

To identify faults, service stations usually use the car’s on-board computer and a laptop with specialized applications. In this case, it is possible to obtain error codes that correspond to various problems. The most common of them are shown in the table.

  obd2 diagnostic connector

Code Description of error P0102, P0103 The mass air flow sensor sends an incorrect signal. P0122, P0123 The throttle sensor provides incorrect information. P0130-P0134 There is a malfunction in the oxygen sensor or damage to the wiring connecting it to the system. P0201-P0204 Clogged or shorted injectors or broken wiring of their sensor. P0300 Problems with ignition (misfires). P0335, P0336 The knock sensor is not working properly. P0351, P0352 The ignition coils are not functioning correctly. When such error codes are displayed, the engine may “trouble.” This problem can also be signaled by errors P2301 and P2304. P0480 Cooling fan is not functioning. P0505, P0506, P0507 The idle speed sensor is faulty. P1602 There is no power supply to the on-board network (the most common error). P1689 Malfunctions in the on-board computer

Please note as in this case it throws incorrect error codes

If errors occur with other codes, you should read the information about them in the file that comes with the car diagnostic application, or search on the Internet.

The controller clears the memory after turning off the engine with the ignition and disconnecting power from the battery for 10-15 seconds. In this way, you can determine after repair whether the malfunction has been eliminated.

Errors in the VAZ 2114 occur quite often, so the ability to recognize them will not be superfluous to carry out proper car repairs. For correct diagnosis, you will need a computer with a special program and an understanding of the on-board computer readings.

Electronic system diagnostics

In order for the work to be completed successfully, first of all, measures are taken to create adequate interaction between the laptop and the car’s electronic system, represented by the on-board computer. As a rule, there are no problems with setup, since the diagnostic program carries out all the activities independently. But if any occur, there is a high probability of disruption of the laptop software. The program, in fact, conducts a complete analysis of the physical characteristics of the car, with a full reflection of the information.

The program's capabilities allow you to determine the location of the throttle valve before starting the engine. Having started the engine, it will determine the number of revolutions, the level of fuel costs and other characteristics. Any car with any electronic systems, with a mounted control unit, can be subject to electronic diagnostics. The method is quite simple, which makes it indispensable in determining the degree of wear and tear of main systems, for example in winter. During this period, the possibilities of preheating the car are determined. If there are violations, a mandatory signal will follow.

For each vehicle equipped with an on-board computer, a corresponding adapter is provided. Why is using an adapter necessary? Firstly, it makes it easier to identify car problems when doing self-repair. Secondly, if there is no goal of self-repair, the driver will have basic information, which will allow him to avoid deception.

One way or another, for drivers interested in personal growth and increasing the level of self-esteem, knowledge and use of this system will allow them to extract only positive aspects that will be useful in the future.

Computer diagnostics of cars has been practiced all over the world for about 40 years. Back in 1980, General Motors installed a diagnostic interface in its cars, through which the condition of all car electronics, as well as the ECM protocol, is monitored.

Then in the USA a universal diagnostic protocol was developed for all brands of cars, which is still valid today, but has a more advanced version - OBD-2. It is applicable for cars manufactured in America and Canada; the Japanese analogue of such a system is JOBD, and the European analogue is EOBD.

Diagnostics

To decipher the error codes that appear, it is necessary to diagnose the vehicle. The machine can be checked in several ways. We will talk about them further.

Car Lada Granta sedan

Diagnostics with a scanner

To check using a scanner, you need to connect the on-board computer “State X1” to the tester or laptop using a diagnostic cable. The scanner or laptop must be equipped with software designed specifically for diagnostics. In our article we will look at an example with the KWP_D program.

In addition to this utility, you will also need to find a specialized OBD-II adapter. It is necessary in order to transfer information from the bookmaker to the laptop via USB output. The diagnostic connector is located next to the gearbox selector, under the cover. You need to connect a scanner to it.

The Check lamp indicates possible breakdowns of the battery

When the program is installed, when you connect, you will see that a COM output with a specific number has appeared in the system. This number will need to be reassigned to any of the four – 1-4. When this is done, the laptop needs to be connected to the bk, then start the ignition and turn on the software.

As you know, any car engine has its own characteristics that determine its operation. If these characteristics differ from the standard ones, it means that something is wrong with the engine. The first point to pay attention to is the DTC characteristic. If malfunctions are detected in the BC system, then open the “Error codes” tab and find the number along with the decoding. Please note: everything will be fine with your Lada Granta if the measured characteristics do not differ from the standard ones by more than 20%.

Diagnostics without a scanner

Checking a car without a scanner is not a difficult task at all. The disadvantage of such diagnostics is that it does not always allow you to identify all errors in the operation of the car:

1. On the instrument panel, press the button that resets the daily mileage. At the same time, turn the key and turn on the ignition, but do not start the engine. In this case, the instrument panel test mode starts, which will help determine whether all panel elements are functioning properly.
2. Then press the button on the windshield wiper lever. Thus, the firmware version of the bookmaker “State X1” will first appear on the screen, and then you will see combinations of possible faults, if any.

Advantages of an auto scanner

“Scanmatik-2” was appreciated even by professional diagnosticians. Having tried this kit once, car enthusiasts were pleasantly surprised that for a relatively low price it allows you to work with a full fleet of domestic cars and an impressive part of foreign ones. When working with the diagnostic kit of this model, you can also use a wireless interface to connect the system to a computer (Bluetooth).

https://youtube.com/watch?v=Q5esXF84-Lk

The OBD-2 connector on Grant regularly supplies power to the diagnostic adapter. In extreme cases, the Scanmatik-2 adapter can be powered from the cigarette lighter. In general, the device is very convenient for performing diagnostic procedures yourself. It even has surge protection. If, for example, you apply current from the cigarette lighter when the system does not need it, nothing bad will happen.

Every device has pros and cons. Many car thieves know how to use the diagnostic connector for their own selfish purposes. As a rule, the diagnostic block is used by criminals to disable the standard immobilizer. A common solution to this problem is to replace the standard block with a “re-pinned” one, with a different arrangement of contacts.

The adapter consists of a “male” (fake connector) and a “female” (standard connector), which is previously removed. It will not be possible to connect standard diagnostic equipment to the new connector without such an adapter, but the chances of saving the car from theft are increased. That's all. Good luck!

For me, the most difficult thing about a car is its “brains”. So I can fix everything myself, but I never get into this computer.

Well, at least the “brains” are not the same as, for example, in Toyota. Nothing can be done there at all without the permission of the BC.

It’s better not to get involved in this system yourself. It's easier to contact a specialist.

Oleg, essentially it’s like that in everything. If you don’t know something, then it’s better to run to a specialist.

What should I do to make the ELM327 connect to the ECU?

If you have such a problem, the first thing you need to do is try to connect the gadget to the corresponding connector located in the car.

The algorithm of actions, in accordance with the instructions, will be as follows:

1. First, you need to diagnose the integrity of the contacts and clean the connector, and then try to connect wirelessly. If necessary, you need to use a special adapter. It is recommended to check the location of the diagnostic connector in the service manual.
2. If the device successfully connects to OBD, you need to start the power unit. After the engine starts, the control unit will either detect the adapter or not.
3. Then you need to synchronize the adapter with your smartphone or computer. The mobile device must operate on the Android platform, since the device does not work with other operating systems. Synchronization is carried out using the Bluetooth wireless communication channel. To do this, you need to go into the channel settings and turn it on by searching for available devices. After the phone detects the device, you will need to connect to it using a specific code. The combination can be different, but, as a rule, these are the numbers 0000, 1111, 1234, 6789.
4. If the connection was successful, you need to launch a diagnostic program on your mobile device. The utility is configured taking into account the features and technical parameters of the vehicle. At this stage, it is important to follow the data specified in the instructions.
5. If all actions are performed correctly, the utility begins the diagnostic procedure. The program will provide information regarding the operation of the power unit and the main systems located in the car, including all controllers and regulators. If synchronization was not successful and the ELM327 does not connect to the ECU, you must add initialization lines.
6. The latter are strictly individual and can be used on certain vehicle models; they must be added manually. All initialization strings are indicated in the service manual or on the Internet.

Engine control unit Lada Granta

As mentioned at the beginning of the article, Granta received new “brains” with CAN support (M74CAN). This innovation is capable of integrating “brains” with alarms and radios with a CAN bus.

They often install a “Standard” controller with Itelma number 11186-1411020-22: This ECU is not compatible with earlier VAZ models. In early VAZs, for example, Priora, the ECU came with a K-channel for data transmission.

Location of the ECU for Granta:

The “brains” are located at the bottom of the front panel, or rather under the glove compartment. It will be better visible if viewed from the passenger seat. The ECU is hidden by sound insulation and upholstery, so it will not be easy to get it out.

ECU firmware:

Serial firmware should indicate an optimized dynamic version for the 1.6-liter 8-valve Granta with an “M74” controller and an exhaust gas emission standard of “EURO-2”.

ECU chip tuning allows you to physically disable the second oxygen sensor (“lambda probe”) along with the catalyst. If this version of the firmware is implemented, this will lead to a significant increase in the dynamic capabilities of Granta.

To find out what firmware the control unit has, use the OpenDiag application, together with a diagnostic adapter connected to the OBD2 connector.

Self-diagnosis

On Grant, the ECM with the M74 controller has built-in self-diagnosis that detects malfunctions. The ECM detects the problem, then the “Check Engine” light comes on and the error identification begins. Then the code is saved in memory and shown on the dashboard.

Did the Check Engine light come on on Grant?

Diagnostics of Lada Granta using ScanMaster.

ScanMaster ELM 2.1 sees the adapter, but refuses to see the controller.

ScanMaster started working and I saw the controller. In the program settings you need to select “USB (FTDI driver)”, provided that the adapter is connected via USB. If the adapter is Bluetooth, select the appropriate settings. The program is also interesting. I haven’t figured it out deeply yet, but it sees the VIN, but doesn’t write what the controller is. Why do I need a VIN number? But the model and serial number of the controller would not be out of place. He also doesn’t see the serial number of the controller - he writes some incomprehensible icons. Fun, but stressful.

I haven’t found any other programs for ELM and CAN for Grants yet.

I also tinkered with ScanMaster - the program is only suitable for viewing errors and erasing them. There are only 14 basic parameters that it shows.

Why, one might ask, is the “Mileage with diagnostic lamp on” parameter needed? What useful information can be gleaned from this parameter and what necessary thoughts in car repair may arise based on this parameter? But, at the same time, this program does not even show the injection time, which, in my opinion, is a fairly necessary parameter, not to mention the parameters of the position of the clutch and brake pedal, on which the limit switches are located and give a signal to the controller. Of course, I understand that these limit switches have only two states - on and off, and this state can be checked with a regular tester. But this is no longer convenient. Maybe, of course, the scanmaster will identify the incorrect operation of these limit switches as an error - I don’t know. And these limit switches, judging by the reviews on the Internet, fall apart quite often. Yes, there is a “PID Configuration” tab in this program - there are a lot of necessary and interesting parameters there, but they are all not active. I haven’t found any information yet on how to activate them. By the way, I saw screenshots of other people’s scanmasters online - there are much more activated parameters there than I have. It's a mystery - I don't have a solution yet.

I tried to find information online about what parameters the commercial OpenDiag shows, but I couldn’t find it. The question arises - pay 5 grand in rubles for the commercial version of the program and see the same minimum set of diagnosed parameters as the free scanmaster? I don’t see the point - it’s easier to go to the dealer under a three-year warranty, and then you’ll see what to do next. Although I used the free OpenDiagnostic (downloaded from the official website, the latest version 1.4) with both K-Line and ELM - the program is normal, it sees a lot of controllers, even M 73, which neither Motor Tester can see (I mean the program for PC, not diagnostic scanner costing over 60 thousand rubles) neither SteVaz nor similar A 2, MyTester. In general, diagnosing Granta on your own in terms of one personal car exclusively for yourself is a rather tedious procedure. Either we use ScanMaster and read only errors (this could also be an on-board computer donated by the dealer), or we take a lot of money (from 60 thousand and above) and buy some kind of Motor Tester or Launcher. Although I had to communicate with 43 Launch, I was also somehow not impressed. Firstly, he basically refused to see vases with a GM diagnostic connector, he saw WAGs with old two-pin diagnostic connectors every other time, he saw only Daewoos of Korean origin, he refused to see Uzbek ones. Some Tatar translation from Chinese into Russian sometimes drove me into a stupor - it was very difficult to understand what he wanted to say. And all this at a price of under 100 thousand.

How to diagnose Granta yourself?

For self-diagnosis of Granta, a regular K-Line adapter is not enough. The ECU installed here is of a different design than on other VAZs; it requires a special adapter. At the moment, it is popular to use equipment such as the ELM-327 diagnostic adapter and various paid and free software for it (for example, Scan Master, Torque).

Photos of the ELM-327 adapter can be found in reference books or on the Internet. Employees of official servers use the “dealer scanner” DST-14 (diagnostic scanner-tester). It is unlikely that you will be able to carry out a complete diagnosis yourself, since this is a complex procedure that includes both software and hardware parts, and not just a K-Line connection. Moreover, it requires certain knowledge and experience. In other words, you need to be able to compare the instrument readings with the real situation.

Self-diagnosis of control unit errors is only a search for possible faults, but it can save the car owner time and money. To do this, you can use a special diagnostic tester (adapter), laptop or smartphone with a special program. During operation, the diagnostic program will collect and provide the user with information about engine parameters in 1-2 minutes.

The motor has certain characteristics that have permissible deviations. In the data table displayed on the monitor by the diagnostic program, you first need to check for stored errors (indicated as DTC). If there are lines like “error 505”, you need to contact automotive websites and forums or a specialist to decipher them.

Some types of software contain transcripts of a significant list of errors. But the ECU may not produce errors, which does not mean their absence. An acceptable deviation is considered if a particular parameter differs from the basic one by no more than 20%. If the deviation is greater, you should look for a malfunction. The most important values ​​include UACC (battery voltage), THR (throttle position), crankshaft speed, mass air flow, coolant temperature.

Frequently asked questions about car diagnostics via a computer or smartphone Lada Vesta

Let's look at the most common issues that arise when servicing this car.

Diagnostics of Lada Vesta sensors via OBD2

The machine's control system is designed in such a way that sensors monitor every moment of the engine's operation. Information is collected and analyzed by the ECU.

Lambda probe

The oxygen sensor is checked by the OpenDiag program and the adapter on the OBD2 block.

• normal state – 0.007-0.7 V;
• inspection required - above 0.8 V.

The schedule should not be jagged, with freezing peaks.

Speed ​​sensor

The element produces a pulse flow, which is converted into a current speed. The software displays the number of signal peaks, with an inverted value.

Idle speed sensor

The scanner displays the step position of the regulator:

Malfunctions of an element or circuit are indicated by errors: P0505, P0506-07, P1509, P1513-14.

Oil pressure sensor

The ECU monitors the state of the unit using two parameters:

• presence of signal;
• lack of communication.

Errors P0522 and P0523 indicate problems.

Air pressure sensor

The service software displays a graph of DC voltage values ​​at the node. Options:

• normal operation – 0.15-4 V;
• muffled internal combustion engine – above 4.5 V.

Circuit malfunctions are recorded by the ECU and entered into memory. OpenDiag reads the errors and displays their meaning.

Air flow sensor

The diagnostic software displays the cell signal voltage:

• 1-1.02 V – good condition;
• 1.03-1.04 V is the permissible limit;
• above 1.05 V – worn sensor.

At this value, the mass air flow sensor should be replaced.

The following elements can be analyzed:

• electronic accelerator;
• knock indicator;
• HF and RV position sensor.

Engine diagnostics via OBD2

The service capabilities of electronic components depend on the scanners and programs used. The OpenDiag application allows you to read engine readings at home, display recorded error codes and decipher them.

Service software allows you to monitor driving modes. Among the available ones: temperature, speed, throttle position, mixture quality and others.

For a detailed look at the M86 sensors and engine management system, check out the documentation below. “Euro-5 Electronic engine management system for 21129 cars of the LADA VESTA family with a controller – device and diagnostics.”

ABS diagnostics via OBD2 connector

The ABS system is diagnosed using a similar scheme. The connected scanner reads information from the brake control unit. Based on the data, a conclusion is made about the need for repairs.

• rotation speed of each wheel;
• valve condition;
• pump motor status.

The test will show the operation of the sensors, the condition of the circuit and contacts.

Intake solenoid valve

Malfunctions of this element can be detected by computer analysis using service software. The Lada Vesta ECU has 5 node error codes:

• P2070, P2071 – mechanical valve sticking;
• P0660, P0661, P0662 – electrical malfunction of the circuit.

For diagnostics, connect the scanner to the OBD2 connector and run the program.

A short summary

What programs and scanners are used to diagnose a VAZ with a GM12 and OBD2 connector?

The programs for diagnosing VAZ are completely different, but they often use programs that are different from each other, and the point here is not even the year of manufacture of the car or the shape of the connector, be it GM12 (also called OBD1) or the usual OBD2. The point is rather that cars with a GM12 connector are more often diagnosed with a scanner manufactured by the Russian company Master Kit BM9213M or its analogues. And newer cars are more often diagnosed with the ELM327 scanner. For this reason, let's talk a little about scanners.

Master Kit BM9213M adapter user manual with scanner connection diagram

The BM9213M scanner is quite suitable for OBD2 diagnostics, but the ELM327 scanner is more often used for this connector. Programs for diagnosing VAZ may be the same to work with both scanners.

Scanner for diagnosing VAZ, Lada and other brands of cars with OBD2 ELM327

To make it at least a little clearer, the ELM327 can be used without problems with VAZ cars with Bosch ECU firmware 7.9.7, which has been installed since 2011. To operate this scanner with cars with lower firmware, you need to use a special pinout of wires from the connector to the scanner or another scanner, for example BM9213M. To learn how to connect the ELM327 to a car with firmware released earlier than 2011 or with a GM12 connector, as well as the programs used for this, see the video below
