Now consider the main functions of the adapter. What data can be obtained using this autoscanner?

What errors can the adapter for auto diagnostics detect?

Using the ELM327 autoscanner, you can quickly view active errors associated with the operation of the motor. In addition, the program helps to identify the main malfunctions and determine exactly in which node they occurred.

So, what data does the program provide and what is its functionality:

1. Reads or clears fault codes in the vehicle. At the same time, all current errors are carefully analyzed immediately after starting the auto diagnostics. If the program detects at least minimal malfunctions in the operation of the engine, then the “Check engine” light comes on.
2. Provides current machine data. This means that the ELM327 mini Bluetooth adapter provides the car owner with all the necessary information about the operation of units that are active in real time.
3. Displays information from the dashboard of the machine. In this case, it is possible to analyze the parameters.
4. Displays graphs. For the convenience of evaluating the operation of systems, the programs provide for the construction of graphs. At the same time, the car owner can independently configure them, turning off and on the necessary information blocks.
5. Performs oxygen sensor testing and much more.

Device advantages

Today, such a device can significantly save on diagnostics. Its cost pays off after a few months of using the device. At the same time, you can check the operation of the systems at any time. For example, if the car began to work poorly on a busy highway, the car owner will be able to determine in a matter of seconds which particular node failed.

Also, the advantages of the device include its compact size, wide functionality, ease of use and low cost. However, the gadget also has a number of disadvantages.

Flaws

Of the minuses of the ELM327, one can single out the lack of protocols for Japanese-made machines. Unfortunately, the owners of these cars have to use other diagnostic tools. Also, some car owners noted that the device is only capable of scanning systems, it is impossible to make changes using it.

Also, after buying the device, you will have to deal with its settings yourself, since there is no instruction in the kit. However, this nuance is difficult to attribute to the minuses, because the installation of the autoscanner is intuitive.

Diagnostics of the vehicle is an important process, because it is with its help that you can find out which parts of the car have problems. One of the devices for car diagnostics is an adapter. For what reasons ELM327 Bluetooth does not connect to the ECU and what to do in such cases? We will talk about this below.

Why does the adapter refuse to connect to the car's ECU?

So why can't the ELM327 see the ECU? What should I do so that the device can connect and see the block? Today on sale you can find many different adapters for testing a vehicle. If you are buying ELM327 Bluetooth, most likely you are trying to connect low quality devices. Or rather, you could have purchased an adapter with an outdated version of the software.

ELM327 Bluetooth devices with legacy firmware use a different Bluetooth module that allows you to communicate with two of the six protocols available. Accordingly, it is possible to synchronize the device with a smartphone, but when you try to connect the device to the control unit, it will inform you that.

So, for what reasons the device refuses to connect to the unit:

1. The adapter itself is of poor quality. Problems can be both with the firmware of the device and with its hardware. If the main microcircuit is inoperative, it will be impossible to diagnose the operation of the engine, as well as connect to the computer.
2. Bad connection cable. It is possible that the cable is broken or is itself inoperable.
3. The wrong software version is installed on the device, as a result of which it will not be possible to achieve synchronization (the author of the video about testing the device is Rus Radarov).

How to solve the problem yourself?

In the event that you are the owner of 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 computer, there is a way out. You can connect to the unit using initialization strings that allow the device to adapt to the commands of the machine's motor control unit. In particular, we are talking about initialization strings for HobDrive and Torque diagnostic utilities for vehicles that use non-standard connection protocols.

As you know, adapters of this type allow you to connect 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 correctly connect the adapter:

1. First of all, you need to connect the device to the on-board computer socket of the vehicle. As a rule, car owners do not have connection problems, but on some car models you have to additionally use adapters. In most cases, the connection socket is located under the steering wheel of the car, sometimes it is located in the glove box or under it. Also, the connector may be located near the cigarette lighter.
2. Next, you need to start the engine of the car - do not turn on the ignition, namely start it. Depending on the car model, the control unit may simply not see the adapter without starting the engine.
3. After that, you need to synchronize the adapter with a mobile gadget on the Android platform, for this a Bluetooth wireless connection is used. To do this, go to the Bluetooth configuration and first enable the function, then search for available items. When the adapter is detected, you need to connect to it, a special code is used to connect. It can be 0000, 1111, 1234 or 6789.
4. When the device is successfully connected to the mobile gadget, you need to go to the utility. In the program, you should find the configuration and configure it in accordance with all the necessary parameters, depending on the car. The setup procedure may vary depending on the software, but the principle is the same everywhere. You need to find an adapter that is synchronized with your mobile phone.
5. If you did everything correctly, then the utility should start working. You will be able to read all the necessary information about the operation of equipment, systems and sensors. But if synchronization failed, then you can try to solve the problem by adding initialization strings. Initialization strings are individual for each individual vehicle model - they are added manually. A list with initialization strings that must be entered when connecting equipment is shown below. For the result to be correct, it is necessary to add to memory only those lines that exactly match the vehicle model.
