The operations that can be carried out depend on the product connected to Tech Tool and the user's authorization level. Note that the screen images shown in the help text may differ from those in Tech Tool depending on the product that is being tested and the user's authorization level.
The first time you select an operation that requires communication with control units after manual matching, the program reads information from the control units. This may take a minute or two. The program make sure that the control units that store the chassis ID and serial number all contain the same chassis ID and serial number.
If the control units which store the chassis ID/Serial no. contain different chassis IDs/Serial numbers, no programming operations except MID XXX Control unit, programming can be carried out (XXX=MID-number).
Note: Testing and calibration operations should not be performed on control units that have different chassis IDs/manufacturing nos., since there is a risk that the result of the operation could be incorrect or that the function could be negatively affected.
Under Test and Calibrate you can select operations to test or calibrate a product.
Note: The functions can be sorted as either functions or function groups.
This section describes the functions available when an operation has been opened.
These steps follow the normal workflow when running a test or calibration operation.
Navigate through the steps in the operation by clicking Continue >. If you want to return to the previous step, click < Back The description of icons that is shown during the steps can be found in the section Run diagnostics (Step 3 of 3).
Note: Since all operations are different, the steps may vary between the operations.
This step contains the purpose and description of the operation.
In some operations you must select a specific component: for example, a control unit or the right or left axle, or a variant of the operation.
This step describes the conditions that need to be fulfilled before you can run the operation. The conditions could be automatically read from the product; otherwise you must manually fulfill and confirm the conditions.
This step executes the operation. Some operations start automatically. Other operations must be run and controlled manually.
This step presents the result of the operation when it is done. After the presentation you must select whether the operations was successfully completed or not.

The wiring schematics shown by clicking on a link in the text field are to be used as a functional description. The schematic shows the conditions that apply when the function is active.
Note: The wiring schematics are not to be used as a basis for circuit measurements.
There are four colors - red, blue, green, and black - used on the wiring schematics
Click this button to check the condition's status. The conditions can be checked at any time except when the actual operation is being run. If the button is grayed-out, there are no conditions for the operation.
Once an operation has been started, the conditions for implementing the operation are checked. In certain cases, conditions are checked even after an operation has been exited.
A window containing conditions and their statuses is displayed. The following status markings are available.
In certain conditions, the sensor value on which the status marking is based is displayed.
Click Cancel to cancel the check.
This section gives a general description of the available presentation elements.
Most presentation elements contain the following components.
In this presentation object, you select which sub-operations are to be activated in the pull-down menu instead of having all included sub-operations presented in order beside each other.
This presentation element is used to read digital signals. The digital signals are linked with various figures. This is for reading status signals in the vehicle control unit, for example.
Below is a list of the various status symbols and what they mean. Other symbols are used in certain operations. These symbols are described in the operations.
The colors of the lamps are listed below. The lamps have different colors depending on how they are defined.
Green lamp
Red lamp
Yellow lamp
Orange lamp
Grey lamp. Signal not active
Error message. A fault has occurred.
Signal not available in this product.
This presentation object is used to calibrate values. Press + to increase the value, or press - to decrease it. When the calibration is finished, press Confirm.
This presentation element is used to deactivate/activate injectors. Click the check box to deactivate or activate injectors. A checked box indicates that the injector is deactivated. Alternatively, keys 1-6 can be used to activate or deactivate the injectors. Key 0 deactivates all injectors.
This presentation element is used to graphically represent how analog signals vary with time. The scales for the various parameters are displayed on the left and right vertical axes respectively. Vertical lines indicating the presence of an external change may occur in this presentation element.
When three or four signals are displayed, the curves can be turned on and off by selecting the check boxes under the graph.
This presentation element is used to read the history of the sensor values. It consists of two tabs. The first tab (1) contains a table with a number of parameter values.
The frozen values that were set when test driven in the factory are given in column (2).
The frozen values which were set after 100 engine hours are given in column (3).
The frozen values which can be set manually are given in column (4).
The first of the 15 parameter values which are continually updated are given in column (5).
The parameters are displayed in a graph under tab (6). Click the button (7) to select which parameters are to be selected. A maximum of five parameters can be displayed at the same time. The name of the selected parameters is displayed at (8). Different units are shown on the vertical axis of the graph depending on which parameter is marked.
Bar charts exist for various purposes (cylinder compression tests and cylinder balancing tests, for example). There may be horizontal lines in the diagram. These indicate the minimum and maximum levels obtained during the tests.
A table is displayed next to the bar graph in which the test values are displayed numerically.
