The procedure for checking the performance of an automobile engine can be performed both visually and with the help of additional equipment, if we are talking about computer diagnostics. One of the devices with which you can diagnose the operation of the motor is the ELM327 adapter. Why ELM327 Bluetooth won't connect to the situation? We will talk about this below.

[ Hide ]

Reasons why the adapter refuses to connect to the car ECU

ELM327 diagnostic devices are equipped with a Bluetooth function, with which the device can interact with the system using two protocols out of six. That is, to connect to the ECU, the car owner does not have to use a wire, since a wireless connection can be provided.

Often, car owners are faced with the problem of the inability to connect a device with a control module, why this happens:

1. You have purchased a defective adapter. In this case, we are not talking about the firmware, but about the inoperability of the hardware stuffing, this is typical for defective devices. If the board is out of order or is initially inoperative, then it will be impossible to check the performance of the motor. Accordingly, how to connect to the control unit.
2. Damaged or defective cable preventing the device from communicating. It is necessary to inspect the wire for damage.
3. Another reason why the connection may be missing is bad firmware. If the software version is too old, then it will be impossible to synchronize the operation of the device with the car (the author of the video is the Kolkhoz channel).

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. Connection to the auto 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 strings for the programs for checking Hob Drive and Torque.

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

1. First you need to connect the gadget to the appropriate connector, which is located in the car. Usually at this stage, car owners have no problems with installation, but depending on the design features of the vehicle, you may have to use an adapter. As a rule, this connector is located under the steering wheel in the passenger compartment, in the glove compartment, behind or below it, sometimes the plug is mounted in the cigarette lighter area. You can find out more about the location in the service documentation.
2. After that, you should start the car engine. By doing this, you will see if the on-board computer detects the connected adapter or not. It is important to start the engine, not turn on the ignition.
3. The next step will be to synchronize the operation of the device with a smartphone, and the latter must work on the Android operating system. For synchronization, both gadgets are connected via a Bluetooth wireless connection. To do this, you need to go to the Bluetooth settings on your phone, activate the option, and then search for all devices on the network. After the phone detects the device, you will need to connect to it, and a code must be used to connect. The combination may be different, but, as a rule, these are the numbers 0000, 1111, 1234, 6789.
4. If the gadget successfully connects to the smartphone, then you need to run the verification software. The software itself must be configured, taking into account the performance parameters of the vehicle. To set up, follow the recommendations given in the instructions.
5. In the event that all the steps were performed correctly, then the software should start checking. With the help of the utility, you will be provided with all the important data on the health of the engine, main systems, as well as controllers and sensors. If it happened that it was not possible to synchronize the devices, then there is also a way out - you need to try to add the necessary initialization lines.
   Please note that these lines are individual for all car models and must be entered into memory manually. These data are presented below, if there are no lines, then they can be easily found on the network. The main thing is that the initialization strings exactly match your car model, otherwise the devices will not be able to synchronize.

OBD (On-Board Diagnostic) means diagnostics and control of the main components of the vehicle (chassis, engine and some auxiliary devices). To conduct an independent check of the systems, the ELM327 diagnostic adapter is most often used - a compact device that transmits data on the operation of the car in real time. All you need to use ELM is a PC running Windows, a phone or tablet running Android or iOS. If we talk about how to use the ELM327, then even a novice car owner can cope with connecting the device.

However, before you start using the device, you need to check the compatibility of the diagnostic scanner with your car.

What vehicles is the scanner compatible with?

To determine which autoscanner is suitable for a personal car, it is enough to determine the data exchange protocols. To do this, you need to look at the OBD-2 block and clarify which contacts are present on it:

• The presence of pin 7 (K-Line) indicates that the ISO 9141-2 protocol is used for diagnostics. These diagnostic connectors are used in Asian and European vehicles.
• Pins 4, 5, 7, 15 and 16 indicate the ISO14230-4KWP2000 protocol, which is commonly used on Daewoo, KIA, Hyundai, Subaru STi and some Mercedes models.

In all the cases described above, you can safely use the ELM327 scanner. In addition, it will work seamlessly with protocols:

• SAE J1850 PWM/VPW;
• ISO 15765-4 CAN 29/11 bit 250/500 Kbaud;
• SAE J1939.

As a rule, the ELM327 autoscanner is installed and connected to any car without any problems.

How to Connect on Android

To connect the ELM327 scanner, a special socket is used, which is located under the steering block of the car (in the cabin).

Healthy! If the scanner is installed on a VAZ and other domestic cars before 2006, then most likely you will need to use an adapter or an adapter.

• Download a small Torque utility from Google Play. This application is considered the best, as it allows you to additionally read the errors of auto systems.

• Connect ELM327 to the appropriate connector.
• Start car engine.
• Activate bluetooth on your mobile device.
• Go to your smartphone settings and go to Bluetooth wireless networks.
• Click on "Search for new hardware".
• Wait until the list of available devices is displayed on the phone screen.
• Select OBD 2 from them and connect to it. To do this, you need to specify a special pairing code, most often it is 1234 or 0000.
• When the ELM 327 bluetooth connection is completed, you can proceed to the settings. To do this, go to Torque and select "OBD 2 adapter settings".
• Next, you need to select the Bluetooth device, that is, the ELM 327 scanner itself.

After a while, a connection will be established, and it will be possible to start diagnosing car systems.

Program interface

If we talk about ELM 327 interface OBD 2, then it is intuitive. After establishing the connection, you must wait until the blinking icon with the image of the car stops blinking. If everything was correct, then the device will immediately start working.

Let's figure out how to use the autoscanner, or rather, which of the icons of the Torque program will interest us the most:

• OBD Check Fault Code - allows you to read and decipher possible vehicle errors.
• Realtime Information - counters that display engine parameters in real time. The user can independently select and add counters that he needs. To do this, click "Add Screen".

• Map View - displays the route of movement.

While the car is moving, the driver can look at the indicators of pressure sensors, speed, fuel consumption and much more.

If you want to receive more detailed data about auto systems, it is recommended to connect to the ELM scanner via a PC.

How to connect on Windows

To figure out how to connect the scanner to a computer, you need to download the ScanMaster program.

Healthy! Before using a program downloaded from the network, it must be installed correctly. To do this, first find a file called "Key" or "Keygen" and generate an access key. After that, you can run the installation file with the ".exe" extension.

After that you need:

• Connect the scanner to the socket in the car.
• Start the car engine.
• Go to the control panel of your computer and go to the "Bluetooth devices" section.
• Click "Add a device" and check the box next to "The device is ready to be discovered" and select "Next".
• For some time, it will search for available devices, after which the autoscanner will connect to the laptop.
• Click "Next" again.
• In the window that appears, you need to drive in one of the standard codes: 0000, 1111, 1234 or 6789.
• Click "Next" again.
• Wait for the automatic integration of the device with the PC and click "Finish".

This completes the installation of the scanner software.

If you are an ardent fan of apple products, and the option of connecting to a PC or Android smartphone does not suit you, then you should purchase a special ELM 327 Wi-Fi model that can be connected to any iOS device.

How to Connect to iPhone or iPad

To get your own diagnostic center to check the operation of the vehicle, it is not necessary to connect to the scanner via bluetooth. More modern ELM models are equipped with a Wi-Fi module, which allows you to use almost any portable device to receive data.

Consider how to establish such a connection:

• Connect the scanner to the socket in the car.
• Go to the section responsible for the wireless connection settings and select the "CLKDevices" network.
• There will be a blue arrow on the right that you need to click on.
• In the window that appears, you need to enter the details of the IP address and router: 192.168.0.11. You also need to specify the standard subnet mask: 255.255.255.0.
• A little lower, you need to specify port 35000.

This completes the setting. Knowing how to use the ELM 327 scanner, it is enough to install any application for quick diagnostics and set the same IP and port parameters in its settings.

However, it should be borne in mind that when setting up private scanners, difficulties may arise.

The most common connection errors

Problems that may arise when connecting:

• The scanner is not connected to the ECU. This can happen for several reasons: the device is not suitable for the brand / model of the car, the adapter or program is incorrectly selected. Sometimes the driver forgets to go through initialization. Less often, the connection does not occur due to a banal mechanical breakdown - the fuse, which is responsible for the operation of the OBD II connector, has failed.
• ELM327 does not show real time data (eg fuel consumption). The fact is that this function is available only while the car is moving.
• Autoscanner does not read or reset errors. Often, a running engine is needed to activate the device, so simply starting the engine is enough. Some cheap ELM327 models do not know how to reset ABS errors, this is solvable, but modification of the device is required.

In custody

ELM327 is a compact device that will save a lot on car diagnostics, it is easy to use and allows you to output data to almost any PC or phone. Nevertheless, before you connect the autoscanner yourself, you should study the video, which clearly shows the process of using ELM.

- this is a special bluetooth device that allows you to quickly diagnose a car, identify errors in the ECU (electronic engine control unit), understand their cause and eliminate them without resorting to the help of qualified specialists (whose services are very expensive).

The elm327 mini brand diagnostic autoscanner appeared on the Russian market relatively recently, but today it is used by a large number of motorists, this fact is directly related to the fact that devices such as the ELM327 BLUETOOTH adapter we are considering have a number of undeniable advantages over a regular visit to a specialist in car diagnostics:

As you already understood, having an autoscanner at your disposal is not a waste of money, but a profitable investment that will save a lot of money in the future.

Characteristics and capabilities of the ELM327 autoscanner

In the delivery set you will find the elm327 bluetooth autoscanner itself, for car diagnostics, as well as a special disk with basic software and elm327 instructions. As a rule, no one uses the disk (since it is in English). Everyone immediately goes to the Internet and downloads the most suitable program, we will talk about them below. The principle of operation of the scanner is extremely simple - you connect the adapter to the engine control unit, then find it via bluetooth using any supported device (smartphone, tablet, laptop), open a pre-installed program and all the data is already in front of you.

Now in more detail about the tasks that this device can help you perform:

• Monitoring of indicators of sensors installed on your car;
• Identification of failed sensors and checking the correctness of sensor indicators;
• Monitoring and reading indicators of error codes (explanation of the meaning of each code);
• Ability to self-reset errors in real time;

In general, the capabilities of the EML327 Bluetooth autoscanner directly depend on the software that you have installed.

As mentioned above, the design of the autoscanner is quite compact, its main part is occupied by a connector with which it connects a special diagnostic socket on your engine control unit. The rest of the device is occupied by a bluetooth module and a chip with a microcircuit for data processing.

If you do not know where the diagnostic connector of the engine control unit is located, try looking in the following places:

• Under the cover of the fuse box;
• In the glove compartment (For example, this is a Renault brand car);
• Under the dashboard.

Compatibility and principle of operation of the ELM327 Bluetooth autoscanner

The ELM327 autoscanner works by connecting the adapter to the ECU using a special OBD-II (On Board Diagnostic) protocol. It is necessary to properly connect to the engine control unit.

Be sure to check the compatibility of your car's ECU with this protocol. This standard has been supported by all American vehicles since 1996, and by European vehicles since 2001 for gasoline engines, and since 2004 for diesel engines. To use the autoscanner on a domestic car, specify the model of the installed ECU (read about this below).

Data-lazy-type="image" data-src="http://androidkak.ru/wp-content/uploads/2017/07/ELM327-Bluetooth.jpg" alt="(!LANG:ELM327 Bluetooth" width="219" height="208"> !} Gadget users are sometimes interested in how to properly connect the ELM327 Bluetooth to an Android device. This tool offers an easy way to scan the OBD-II system and read the PID.

The ELM327 is a low cost computer diagnostic tool. It can be useful even for experienced professionals who for some reason do not have access to specialized scanning tools. But before you install it, you need to find out all the nuances.

What gadgets are compatible with this device

The most common problem with the ELM327 is that some budget scanners have unauthorized copies of the microcontroller. These chips often exhibit strange behavior. In addition, even legal equipment refuses to work with some devices. If the user wants to use the iOS or Android gadget as a diagnostic tool, then he should pay attention to the above problems.

The scanning tools, which include an ELM327 microcontroller and a Bluetooth chip, can connect with many devices, but there are certain limitations. Mostly smartphones, tablets and laptops work with this tool. The most convenient way to make an ELM327 Bluetooth connection is to connect the scanner to your phone. But not all smartphones support this technology. The blacklist includes Apple iOS products such as the iPhone, iPod Touch, and iPad.

The reason why the above devices usually do not work with ELM327 scanners is because they have a peculiar approach to Bluetooth signal processing. Most Bluetooth scanners can't pair with Apple products, which means they're better off using USB and Wi-Fi protocols. The exception is Jailbroken devices, but their use can lead to unpleasant side effects. In some cases, other smartphones may also have problems with ELM327 scanners. Typically, these problems are associated with unauthorized copies of microcontrollers that do not contain updated code.

Timely information about the condition of the car is very important for any motorist. It is necessary in order to troubleshoot in time and thereby prevent the vehicle from failing.

However, constantly monitoring the state of the machine is quite problematic, because it is a complex mechanism consisting of many components and parts. It is simply unrealistic to regularly carry out a meticulous check of every little thing. Car diagnostics in a car service is a rather expensive thing. It is usually performed when real problems arise. But sometimes by this point the problem becomes more serious than at the initial stages, and its elimination requires serious financial costs.

The most common and functional program for ELM 327 Android is Torque
