Open Function Blocks View: The next step is to create a function block to control the diagnostic services created. Open the Function Blocks view selecting **Scripting and Automation> Function Blocks**from the main menu. ### 2. Create a Script Function Block: Click the **+ button** and select **Script**. Change the description of the function block to something more descriptive like **Program ECUs**. ### 3. Write the Script: Now a script needs to be entered. For this task 6 steps will be needed. The steps needed and descriptions of what they do are found in the **Table 1**. For the **Diag Job Action**, double clicking on the **Value** cell will allow selection of the diagnostic job to act on and how to act on it. For more information on this command see the help for the [Diag Job Action command](/vspy-3-documentation/3.9.16/vehicle-spy-main-menus/main-menu-scripting-and-automation/function-blocks/function-blocks-types/script-type-function-block-commands/script-type-function-block-command-diag-job-action.md). **Table 1: Function block parameters**

Step	Command	Value	Reason for Step
1	Diag Job Action	Start DW CAN ECU	Starts, or launches, the diagnostic service.
2	Diag Job Action	Wait until Complete DW CAN ECU	Waits at this step until the selected diagnostic service is finished. When completed, continues to the next step.
3	Wait For	5.000 Sec	Waits for 5 seconds. This is not needed, but provides a delay so script progress can be monitored by the user.
4	Diag Job Action	Start SW CAN ECU	Starts, or launches, the diagnostic Service.
5	Diag Job Action	Wait until Complete SW CAN ECU	Waits at this step until the selected diagnostic service is finished. When completed, continues to the next step.
6	Stop	n/a	Ends this function block.

### 4. Configure the Start Setting: On the **Start** tab select **Manual Start**. This allows the Script function block to be started using Graphical Panel controls that will be set up in the next part of this tutorial. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.intrepidcs.com/vspy-3-documentation/3.9.16/vehicle-spy-tutorials/tutorial-dps-programming-automation/part-2-create-function-block-to-launch-programming-services.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
