For automotive technicians who need to diagnose complex issues, the ability to use both a scan tool and an oscilloscope at the same time can be invaluable. This method, particularly useful with a Modus Equivalent Scanner Obdii, allows for simultaneous output control and signal verification for a more comprehensive diagnostic approach. While it might seem a bit involved initially, this technique becomes routine with practice.
To begin, envision your Modus equivalent scanner OBDII already configured and actively controlling the system output you are testing. Now, to integrate oscilloscope verification without interrupting your scanner session, start by tapping the “Home” tab located at the bottom of your scanner’s screen. This action is crucial as it navigates you back to the main diagnostic suite while importantly keeping your scanner session running in the background.
Next, from the diagnostic suite menu, select “Guided Component Tests.” It is essential to choose this specific option and not “Lab Scope” directly, as selecting “Guided Component Tests” is the necessary pathway to enable this dual operation. After selecting “Guided Component Tests,” choose any test from the list – the specific test selected is not critical because you will be manually configuring the oscilloscope settings to your specific needs in the following steps.
Once you have chosen a test and the oscilloscope interface appears, ensure you have selected the correct test lead on the appropriate channel and that your probes are correctly connected to the circuit under examination. Adjust the voltage and time scales on your oscilloscope to appropriately capture the signal you expect to see. At the top of the oscilloscope screen, you will find a tab labeled “Meter.” Tap this “Meter” tab once to hide the on-screen instructions, and tap it a second time. This second tap will detach the oscilloscope display into its own separate window. This detached oscilloscope window remains active and can be found on your operating system’s task bar, typically located at the bottom of the screen.
Now, return to your scanner interface by again selecting the “Home” tab. From the home screen, re-select “Scanner.” This action will bring you back to your active scanner session, exactly where you left off with your output controls. With both tools now running, locate the “Meter” tab on the task bar – clicking this will bring the detached oscilloscope window to the forefront, positioning it to float directly over your scanner screen. This overlay setup enables you to view and utilize both the scanner and the oscilloscope concurrently, providing a powerful and integrated diagnostic environment.
For technicians seeking a visual demonstration of this technique, the Scanner Danner Premium Verus training series includes a video tutorial that clearly outlines these steps. While the video specifically references the Verus, the core principles and steps are directly applicable to the Modus and Modus equivalent scanner OBDII platforms. If you are unfamiliar with Scanner Danner’s resources, consider taking advantage of their 14-day free trial to access this valuable training material. This trial period offers ample time to review this specific series and other relevant content, and allows for cancellation before incurring any subscription fees if you choose not to continue with a premium membership.
By mastering this method, automotive technicians can significantly enhance their diagnostic capabilities by leveraging the strengths of both scan tool control and oscilloscope waveform analysis in a synchronized and efficient workflow when using a Modus equivalent scanner OBDII.
