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

Ways to solve the problem on your own

If you are sure that the software version is working, in particular, we are talking about firmware 1.5 and higher, then you can solve the problem on your own. Make sure that the device has all 6 protocols out of 6. Connecting to the car control module is possible using initialization strings, this will allow the device to adapt to the ECU commands. In this case, we mean the initialization lines for the programs for checking Hob Drive and Torque.

To solve the connection problem, you must proceed as follows:

Photo gallery “Initialization strings”

1. Initialization data from the ECU 2. Initialization data from the ECU

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?

Reviews of OBD2 diagnostic car scanners

This section provides descriptions of diagnostic scanners and adapters. Before purchasing a scanner for your car, it is recommended that you read reviews of the most popular equipment models.

How to solve the problem yourself?

If you own a device with the correct firmware version 1.5, where all six of the six protocols are present, but the adapter does not connect to the ECU, there is a way out. You can connect to the unit using initialization strings, which allow the device to adapt to the commands of the machine’s motor control unit. In particular, we are talking about initialization lines for diagnostic utilities HobDrive and Torque for vehicles that use non-standard connection protocols.

As is known, adapters of this type allow connection to the control unit in most foreign-made vehicles manufactured after 1996. So, how to solve the problem on your own?

First you need to connect the adapter correctly:

Scan Tool Pro - budget multiscanner for Lada Vesta

A good choice for a novice diagnostician

Nowadays there are scanner models with different versions of firmware and chips on sale. Scan Tool Pro with firmware 2021 is the most stable version so far, and also has maximum compatibility with cars manufactured since 2001, including Lada Vesta.

Why doesn't the auto scanner see the car?

Despite the advancement of many of the latest models of car scanners, sometimes problems still arise with connection to the car’s electronic control unit. Such situations arise not only for technical reasons, but also due to the human factor, when the car owner has not studied the operating instructions in sufficient detail or neglected some points of the connection procedure. Let's take a closer look at the most common reasons why the scanner does not establish a connection with the on-board computer.

Defective adapter.

If you purchased a scanner at a price lower than most sellers, this is not a reason to celebrate. If it works by itself, but does not see the car, then it is quite possible that you bought a low-quality product. Moreover, this does not apply to the firmware, which can always be reinstalled, but to the hardware. Therefore, to purchase a high-quality certified product, it is better to visit a specialized website. This is the only way you can be sure that you won’t end up with a fake.

Damaged connection cable.

Although trivial, it is a fairly common reason for a lack of connection. Despite the fact that almost all manufacturers equip their devices with a Bluetooth wireless communication module, many car owners, the old fashioned way, prefer to use a cable connection. Naturally, due to frequent use, the cord can be damaged at the point of bending or entering the connector.

Old firmware version.

It is logical that the latest car models are equipped with more advanced on-board computers, which may easily not recognize outdated scanner software.

The engine is not started.

Sometimes drivers simply turn on the ignition, but do not start the engine. A running engine is a prerequisite for the car to recognize the connected adapter.

After the smartphone, laptop or tablet detects the scanner via Bluetooth, it is important to fully establish the connection. This usually requires entering a simple code specified in the instructions, for example, “0000” or “1234”.

No special program installed.

To receive information from sensors and car components, you need not only to provide a connection, but also to install a special program (or an application on a smartphone) that will convert encoded data from the control unit into a graphic image or digital expression.

Frequently asked questions about auto diagnostics via a computer or smartphone

Engine diagnostics

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

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

ABS diagnostics via OBD2 connector

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

Diagnostics of mass air flow sensor

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

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

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

Diagnostics of the oxygen sensor (lambda probe)

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

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

Automatic transmission diagnostics

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

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

Automatic transmission errors:

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

Diagnostics and testing of the electronic gas pedal

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

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

Typical errors related to the accelerator pedal:

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

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

EUR - electric power steering

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

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

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

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

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

Electric power steering error codes:

11 - The system is working; 12 - No engine speed signal; 13 - Malfunction of the torque sensor; 14 - EMUR engine malfunction; 15 - Malfunction of the steering shaft position sensor; 16 — Malfunction of the EMUR engine rotor position sensor; 17 — Malfunction of the car’s on-board network (below 10V or more than 18V); 18 — Malfunction of the EMUR control unit; 19 - Vehicle speed sensor malfunction.

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:

On a mobile device (smartphone/tablet):

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:

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.

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.

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.

Universal solutions

If the phone does not see the Bluetooth ELM327 device, then first of all make sure that this is not one of the simple problems:

If these instructions did not help and the ELM327 Bluetooth device does not work, then consider other possible problems and their solutions.

The phone does not see ELM327 Bluetooth

In this case there are not many options:

ELM327 does not connect to the ECU

If the smartphone sees the ELM327, but it does not connect to the electronic engine control unit (ECU), then you have encountered the most common problem. ELM327 Bluetooth does not communicate with the ECU due to the adapter, car brand or application.

If you were unable to solve the problem by installing a special application for your car brand, then you need to register the parameters (initialization string) in the software settings. For example, in the popular Torque program. Go to the profile editor, select the protocol and enter a string in the last field.

Communities › VAZ: Repair and Modification › Forum › Problems with the “ELM327 OBDII 2” scan

In general, I bought a scanner for the ELM327 OBDII 2 car on Ebay. I was happy as hell. I went to try it by car. I connected it, turned on the “Torque” program, I thought now everything would be on fire and all the sensors on the display would come to life. But here a problem arose. All connections are there, but there is no connection with the ECU. Whatever I did, damn it, the ECU doesn’t respond. I tried it on other programs, there was no connection with the brain. Here I have a question: Does anyone know what this garbage is? Maybe this scan doesn’t fit the VAZ? But I saw on the drive how the same scan was connected to a Granda and everything worked. Car VAZ2113.

Elm 327 is not friendly with vases. I bought it too... then I bought a master kit VM9213 and everything worked. On the Kan bus grant, that’s why it worked. So don’t worry, buy this www.masterkit.ru/main/set.php?code_id =215984 works with vases 100%

Damn, it sucks. Just as far as I know, the version with “USB” is suitable, I hoped that “bluetooth” would also be suitable.

I bought the USB version. It doesn’t see VAZ’s brains

You're right, he doesn't see them. More precisely, he sees, but on the VAZ 2114 since 2012.

In my opinion, he partially sees Bosch 7.9.7. And since 11, he has adopted Bosch M 74 e-gas (electronic pedal), maybe he will take Bosch M 73, I don’t know.

7,9,7 he is visible 100%. I posted a list of suitable Russian cars a few messages below.

Damn, it sucks. Just as far as I know, the version with “USB” is suitable, I hoped that “bluetooth” would also be suitable.

I have bluetooth and everything works, try it through the ScanMaster program

He sees you because you have a 2012 car and there are other brains there.

I have a 2008 car. And it doesn’t seem to depend on the brain!

The list of suitable cars says differently.
