Run the program installed on your computer or mobile device.

Click the button at the top of the window, an additional side menu will appear.

Click the "Options" button in the side menu, you will be taken to the program settings window.

Consider the items in this window.

If "I agree to send bug reports" is checked, the program will send internal error reports automatically.

If you have disabled automatic sending of error reports, you can send all accumulated information manually by pressing the Send logs immediately button (internet access is required).

We only store data on malfunctions and problems, as well as statistical information. For example, which error codes occur most frequently on which vehicles. No personal information is stored. You can read more about the information we collect and store in our privacy policy.

For more information about working with tech support, see page Contacting technical support

The Get firmware button downloads the firmware for your scanner from the server (internet access required).

The Update firmware on the device button writes firmware to the adapter (requires connection to the scanner's Wi-Fi network).

You can select different options for displaying the interface

Opening of new modules (brands)

The modules are “attached” to the serial number of the adapter and cannot be transferred to another scanner.

After purchasing a new brand from a dealer, you need to update the firmware on the device. If several scanners are attached to your account, then the firmware is downloaded for all your adapters, although new modules may not be open on all scanners.

1. Click the button at the top of the window, an additional side menu will appear.
2. Click the "Options" button in the side menu, you will be taken to the program settings window.
3. Click the Get firmware button (internet connection required), you will need to enter the serial number of your scanner.
4. Click the Update firmware on the device button (requires a Wi-Fi connection of the scanner)
   The program will be written to the adapter and it will automatically will reboot.

Work with several adapters

Several adapters can work in one local network (for example, in one room you can work with several adapters at the same time).

To quickly switch between adapters, you need to create shortcuts.

Run the local version of the program installed on your computer or mobile device.

Click on the button at the top of the window, an additional side menu will appear.

Click on the "Options" button in the side menu, you will be taken to the program settings window.

Go to Shortcuts for devices.

1. Click Add shortcut.

2. Enter a name for the adapter shortcut. We recommend writing the adapter serial number. Then you will not confuse them.

3. Enter the IP address of the adapter.

4. Click Add

Now in the side menu you will see a shortcut to your created adapter.

Work with the program

First, select the car and the system you want to work with. All car brands are divided by region (Europe, America, Asia, etc.).

ECU selection

First of all, you need to choose a car and a system with which you want to work. This can be done in two ways:

1. Select by VIN number

1. To automatically search for systems in a car, enter its VIN or KBA number in the main window and press Enter.
2. If it is not possible to enter the VIN number, you can make an automatic search for car blocks, press the button with the magnifying glass .

2. Select manually

You can select the ECU block manually. Left-click on a tile, for example, make, model, vehicle ECU.

System selection window

The system selection window is divided into groups for clarity: engine, chassis, body and multimedia.

You can quickly find the desired ECU unit.

You can also see the car card here.

Here is information about the car, the maximum number of ECU units.

If you got to this window by entering the VIN code on the main page, then the card will also show additional information.

Function buttons that apply to the entire vehicle, not to any specific ECU.

Let's take a closer look at the functions.

Automatic search

During automatic search, the program tries to connect to all possible ECUs for this car. If the ECU is present, the program reads the identification, codes and DTCs from it.

Sometimes, during auto search, the program may ask you to clarify additional information about the car, for example, what type of air conditioner is installed on the car.

The more ECUs that can be present in the car and the slower the communication protocols with them, the longer the automatic search takes.

Blocks of the ECU with which the program could not communicate will be hidden.

You will see a list of found ECU blocks for your car and primary information for analysis.

If the VIN number was read during autosearch or a search was performed by the VIN number of the car, then the program automatically remembers the list of found ECU blocks and saves it to itself. The next time you search for the VIN of the same vehicle, the program will not show the maximum list of ECUs, but the finished search result.

ECU tiles

Tiles are sorted into groups (engine, chassis, body and multimedia), and within groups alphabetically (left to right, top to bottom).

Graphically, ECU blocks are presented in the form of tiles, which consist of:

1. System icons;
2. ECU block names;
3. Additional identification information (VIN, mileage);
4. Buttons for quickly clearing DTCs;
5. Indicator for the presence of the configuration change function in the ECU;
6. DTC error list.

The ECU icon may have several colors depending on the test results:

This is done in order to focus attention on problematic ECU blocks.

During autosearch, the program compares VIN numbers from ECU blocks and, if they do not match, then the VIN number is highlighted in red.

The program does not compare mileage, because mileage may vary slightly in different ECU units.

If the DTC has the status "active" or "current" then it is highlighted in red, otherwise it is highlighted in gray.

Update

The " update" function differs from autosearch in that it does not try to contact all possible ECUs, but uses a list that was previously prepared by autosearch.

This saves time if it is known for sure that the number of ECUs in the car has not changed since the last visit.

For example: You connected to the car for the first time, performed auto search, saw DTCs, connected to the desired ECU, performed diagnostics. Now you need to put aside the scanner and repair the car. After the repair, you need to diagnose the car again. It makes no sense to re-search for all possible blocks.
To perform a quick update of information on ECU blocks, press the button.

Clearing all DTCs

The button clears DTC errors in all found blocks.

Usually used to quickly erase DTCs in all ECUs of the car, without having to go into each ECU individually.

Press it, then reread the ECU blocks with the button to control.

Position of the diagnostic socket

If you press the button, you will see the location of the diagnostic connector in the selected vehicle.

Sometimes the OBD-II connector may be in an unexpected place, such as in the glove compartment.

Sending data to QClients

Using the button , you can save the auto-search data in the QClients accounting program for later analysis, saving or printing.

Fast Print

Press the button , the program will send the results of the current autosearch to print.

Quick Print is useful when you want to quickly print out a list of ECUs with DTCs and do not need to save the auto search data.

List of utilities

Click on the button , the program will show a list of all available utilities in the car.

To run a utility, click on its name.

This speeds up the work, since you do not need to look for which block contains the required utility. For example, the steering sensor calibration may be in the power steering unit, or it may be in the ABS unit.

Here you see the actual list of utilities that are present in this car, not a list of all possible utilities. This list will also be stored in the program under the vehicle's VIN number. The same car model with the same engines may have different configurations and the software in the ECU units may also support a different list of utilities.

The list of utilities can be sorted by name, favorite utilities or by the system in which it is located. To sort, click on the table column heading.

If you click on the star icon in the list of utilities, the utility will be added to the list of favorites. In this case, it will appear on the auto search page under the car card. Now the utility can be launched from the autosearch window.

If a utility with the same name is found in another car, it will immediately be displayed on the auto search page.

Clicking the star icon again removes the utility from the list of favorites and from the autosearch page.

Entrance to the ECU

Click on the tile with the name of the ECU block to enter it.

After communication with the electronic control unit (ECU) is established, the program will show the tabs of the diagnostic module.
In different ECU blocks there can be a different number of bookmarks.

The DTC tab shows the number of errors at once.

Depending on the type of ECU or diagnostic protocol, it may take from 0.5 to 15 seconds to start working with the ECU. Some ECUs require more time. This may be due both to the peculiarities of the diagnostic protocol itself, and to the reading of the vehicle configuration by the scanner.

For quick access to bookmarks, access is provided by the keys on the keyboard.
The Esc button on the keyboard corresponds to the Exit button in the program.
The number keys on the keyboard correspond to bookmark numbers. At the bottom of the bookmark, a hint number is displayed for a quick transition.
For example, to switch to the "Error Codes" tab, press the  2  key on the keyboard.

In the identification section, you can see the passport data of the control unit. This data is necessary to determine the software and hardware version, the calibration version of the control units. The identification data also contains additional information necessary for the correct diagnosis of this control unit.

To go to the next bookmark:

1. Press the Back button and then to another bookmark;
2. Or click on the bookmarks button at the top.

The bookmark buttons will be hidden if the screen resolution is not enough to display them in one line.

Most ECUs, in addition to storing the error number, can show the current error status in an additional column. Statuses show additional information on the code. For example, that the code is active or was, but is not available at the moment.

The scanner reads the error code and decodes it. The error can be numbered either by the manufacturer or by the OBD-II standard.

To send a command to clear DTCs from the ECU, press the Clear DTC button

The OBD-II standard also provides for codes defined by the manufacturer. These codes start with P1000.

Errors defined by the OBD-II standard

Some manufacturer's standards assume only a numerical value for the error.

Some units support Freeze frame mode. When an error occurs, information about certain parameters is written to the memory of the control unit. This allows you to determine the conditions under which the error occurred. Freeze frame is recorded separately for each error.

If there is a Freeze frame for the error, then the name of the error is displayed in orange font as a link. To obtain information, left-click on the name of the error. Freeze frame will be displayed below the error.

Some ECUs provide multiple Freeze frames for the same error code. Typically, data is stored before, during, and after the occurrence of the DTC.

If there is no decryption for the error code, then you should contact technical support.

In the "Data stream" section, you can view the current information, read, actuators or status data that are requested from the control unit in real time. The parameter has a name, a value, and, if necessary, a unit of measurement.

Parameters, values and units are displayed here.

The list of parameters can be scrolled with your finger or the mouse wheel. At the same time, please note that only the data that you see on the screen is requested from the control unit. And after scrolling, it may take some slight time for the data to appear. This time depends on how fast the control unit can send data.

In ECUs that work according to the ISO-9141, KW71, KW-1284 protocols, each diagnostic parameter is requested by the scanner separately. Each request takes about 0.1 seconds. Therefore, it will take about 1 second to display 10 parameters on the screen. The more parameters that are displayed on the screen, the longer it will take to update the screen.

Click on the name of the parameter, you will see the parameter in the form of a graph. If you click again on the name, the parameter will be displayed in digital form. 

In addition to the name and values, the graph shows:

1. Limits;
2. Average value;
3. Minimum and maximum peak values of the visible part of the graph.

If there are few charts on the screen, they will be stretched to the full height of the screen. If there are many, then the graphs will be of a fixed size and you can scroll through them.

Datastream control

1. Buttons (pause) and (stop) allow you to stop the graph;
2. After stopping, the measuring ruler becomes available.
   By pressing the left mouse button or finger (for phones and tablets) in the graph field, we can set the ruler to the desired place in the graph;
3. In this case, this figure will show the value of the parameter at the place where the ruler is established.

The difference between the "pause" button and the "stop" button is that if you continue reading after the pause mode, the previous data will remain, and after the stop button, the graph will be cleared. Pause mode is needed when you want to see a few fast-moving moments in the background of a lot of time. You stopped at some point, and then you know that for a long time you will not have the information you are interested in. Press pause, and before the right moment, start reading again. The graph saves 1000 readings. For a fast-paced schedule, this is approximately 3 minutes of recording.

By swiping or dragging the graph with the left mouse button held down, you can scroll the graph horizontally.
In stop mode, data is not read from the control unit. To continue reading the parameters, press the button .

Buttons (plus) and (minus) - change the time scale.
Each press of the button increases or decreases the time by half. The scale you choose is automatically saved in the program settings. The next time you start the program, the last selected scale will be set.

Graph Display Modes

The first mode is called open entry mode.

This is a mode with automatic vertical scaling. In this mode, the program automatically calculates the scale in such a way that the visible part of the graph occupies the entire space in height, starting from the minimum value of the graph or from the zero line. So, you see the entire range of chart changes in the most detail. This is the main and frequently used mode of working with charts.
But you need to take into account one nuance. Since autozoom constantly adjusts to the current visible values ​​of the graph, you may not see what you expect. Here is an example of recording from wheel sensors during braking. The car stops, the speed graphs go down, and just before the stop, you see that the graph goes up. This can be confusing. This happened because at this moment the scale of the graph has increased, and it already shows a range of very small changes in speed. According to this advice. If you want to watch the current changes slowly, then either set a larger time scale or just pay attention to what range is currently set vertically.

The second mode is called сlosed Entry Mode.

This is also a mode with automatic vertical scaling. It works in the same way, but unlike the previous one, here the scale is set not from the zero line, but from the minimum to the maximum of the chart. This means that the constant component of the graph is cut out. This mode is needed when you want to see slight fluctuations in the chart against the background of a large constant shift. For example, you want to see fluctuations of a few atmospheres against a constant displacement of a hundred atmospheres.

Third mode. This is normal mode without autoscale.

The graph is shown in the entire possible range of the parameter. The range of the graph change is not always set by the manufacturer, and then the range is taken from the maximum value of the number. These values can be very large, and then you may not see the change in the graph.

Select the display mode depending on the situation.

- button to show all parameters in the form of graphs or digital form.

If there are a lot of parameters, then depending on the power of the computer, there may be a slight delay in response.

123 - Options for displaying parameters.

You can select 1, 2 or 3 columns. Depending on the screen resolution, these buttons are hidden by
(for example, only one column will be shown on a mobile phone screen).

Each parameter has a parameter selection checkbox on the left

By setting it we mark the parameters for further work.

1. Select one or more options;
2. Click on the selection button ;
3. Only the selected options will remain on the screen.

Эit is necessary when you want to get the maximum display speed of the parameter and see its fast changes. The more parameters you see on the screen, the slower they appear. Therefore, if you need to watch fast changes, choose fewer parameters.

Another press of the select button returns to normal mode

The button deselects all parameters.

This is convenient when there are a lot of parameters and you have marked them in different places. And in order not to search for them throughout the list, you can simply click this button.

The dropdown list is a filter selection.

For more details, see the Working with filters section.

Search bar.

If you need to show only those parameters in which a specific word or abbreviation is mentioned, for example "DPF", start writing it in the search bar, as you type, parameters will be selected in the name of which the word "DPF" is present.

To cancel the selection of options, delete all text in the search bar.

The selection is carried out by all subtracted parameters, even if they are not shown on the screen.

Additional control buttons

Indicators

- indicator button.

Indicators are fixed parameters that are used most often. Indicators are needed for a quick assessment of the main parameters.

Graph Overlay

- button for chart overlay mode.

This mode is needed to view related parameters. For example when viewing throttle position sensors. This mode is activated when there are checked parameters. The graph can show from one to 4 parameters.

It works like this:

1. Choose from 1 to 4 parameters;
2. Click the overlay graph button .

1. The control buttons work the same as in normal charts;
2. By clicking on the checkboxes, you can disable or enable the visibility of the parameter;
3. To exit the overlay mode, press the button again.

Schematic mode

- the button turns on the "schematic" mode.

The diagram shows which components are installed in the system and the meaning of key parameters.

The scheme for each control block is built automatically based on the names of the parameters that are present in the control block. It is needed so that you can quickly assess what is in the system. For example, how many lambda sensors. Is an air mass meter or intake manifold absolute pressure sensor, etc. installed.

The circuit is also needed in order to quickly find the parameters of these components.

The scheme is not present on all devices.

The scheme cannot be enabled on smartphones, this is due to the small screen size.

The appearance of the program, set in the settings, also does not affect the display of the scheme.

To resize the scheme, drag the slider. This is convenient if the circuit is large and few parameters fit on the screen.

The size of the scheme is saved in the browser settings and the next time you open the diagram, it will be the same size as you set last time.

In essence, the scheme is a set of filters.

1. If you press your finger or the left mouse button on a component in the diagram, then the preset filter will turn on and only those parameters that apply to this component will be shown in the data stream.
   For example, let's select the parameters for oxygen sensors;
2. Filter installed;
3. The name of the filter is displayed here.

By clicking on the various components of the circuit, we can find the desired parameters. If we want to collect parameters from different systems, then we can mark these parameters by checking the checkboxes.

1. To reset the filter, press the button
   Resetting filters and resetting flags are not the same thing. Resetting filters does not affect the options you choose;
2. For example, now, after resetting the filters, you can leave only the marked parameters on the screen by pressing the button .

If a DTC is stored for a component in the control unit, the component will be highlighted in red flashing.

If you see a system in the diagram that is not really present in the machine, this does not mean an error. Some control units are created as universal for a group of motors. Their set of parameters may contain systems that are not available in a particular motor. 

The chart and indicators can be opened at the same time.

1. Button adds visible data to the QClients database;
2. The print button generates a report file in a new browser window. All visible parameters will be added to the report. The report can be printed or saved as a PDF.

When installing the program, we offer a basic set of filters. We deliberately did not make a complete list, because diagnosticians have individual methods, and it is easier to add to the filter than to remove from it. You can delete them, create your own or edit them. You can do this in the settings.

Click on the button at the top of the window, an additional side menu will appear.

Click on the "Options" button in the side menu, you will be taken to the program settings window.

At the end of the list of settings there will be an item "Filter sets".

To create a new filter, click the Add Filter button.

The filter editing window will appear:

1. Filter name (enter a unique name to make it easier for you to search for this filter among others);
2. List with parameters added to the filter;
3. General list of all possible parameters;
4. Remove filter button (if you want to delete the entire filter);

How to quickly create a set of your parameters:

1. To quickly find a parameter from the general list, enter its name in the search bar of the right table (on the right - a table with all possible parameters);
2. Select the one you need and check the box on it, now the parameter has appeared in the left table (on the left is the table with the parameters you added);

If you need to remove a parameter from your filter, uncheck this parameter in the left table.

The filter is saved automatically, after editing the list of parameters, just press the button Cancel

Above the list of parameters in the data stream, you can see a drop-down list with filters.

Click on the name of a filter to apply it to the current list of options.

If the parameters that are in the filter are not in the current ECU, then the filter name will not appear in the drop-down list.

If you apply a filter, then only those parameters that are in the filter and are present in the ECU will be displayed.

1. Select a filter from the list;
2. To the right of the drop-down list you can see the name of the applied filter;

To cancel the filter and show all parameters from the ECU again, press the (clear filter) button.

To quickly add a parameter to a previously created filter:

1. Select one or more of the required options with the checkbox;
2. Click the button (add to filter);
3. In the new window, select the filter to which the parameter will be added.

The options you selected will now be in the filter.

Parameters that are the same or close in meaning can be named differently in different control units.
Add parameters to the filter while working and after a while your filter will accumulate all possible combinations of the necessary parameters and you will very rarely add new parameters. Do not worry that the filter has something that is not present in this block. The program will show only those parameters that the filter will contain hundreds of similar parameters. The main thing is that they are needed for this case.

Saving data to Clients

You can save the data stream. To do this in the data stream window, click the button.

The data will be saved to the Clients program on the current device.

You will see an alert in the upper right corner of the program when the save is successful.

The list of actuator tests depends on the specific ECU model.

Select an actuator, you can control it using buttons or knobs. Sometimes, for convenience, the current readings of some parameters are displayed. Each actuator is tested in its own way.

Often additional parameters need to be monitored. For each test, a filter is provided. If there are parameters for it, then it turns on automatically.

If some parameters are missing, then you can add them yourself:

1. Select the general list of options;
2. Select the required one or more parameters;
3. Click the (add to filter) button. Unlike the data flow, you cannot select a filter because there is only one filter in the test.

There are brands that do not allow you to run tests against the background of data flow. For example, the VAG group, so there will be tests only with the data flow that the manufacturer has provided.

This section contains specialized functions of the ECU, such as adaptations, resets, etc.

Utilities are also launched by clicking on the tile with its name. Read the description carefully, if any, and follow the conditions of the ulilith.

Whatever function you run. The first window will always be informational. Running the test utility or coding will never start the procedure as the first step. Therefore, you can safely run the utility and read its description.

The configuration is also often referred to as coding.

The number of encoding parameters depends on the specific ECU model.

Here you see the name of the parameter, its current state, and the new state that can be changed.

1. To highlight the parameters that you have changed, the program highlights the value in blue if it has been changed;
2. If the parameter cannot be changed, then there will be no drop-down list. But the current value of the parameter will be shown.

In the options there is a "Configuration Data" option. This is the hex code for the entire configuration. When you make a change to the dropdowns, this code also changes. 

Change the required parameters and click the Ok button, the scanner will write data to the block.

Additional buttons for working with the configuration:

• - button displays the history of configuration changes for this vehicle on the screen;
• - save configuration data button. The configuration will be tied to the machine's VIN and stored in the QClients program;
• - button to load configuration data from QClients.

With each entry, the configuration is saved automatically and linked to the internal name of the control unit. Once you've made an entry, you can revert back your changes with the button (History of changes).

Work in different versions of the program

You can work either in the old or in the new version of the program. The scanner must have the firmware of the version of the program with which you want to work. Therefore, if you want to upgrade to a different version of the program, you must enter the scanner into download mode and perform a firmware update.
