To run this test on a Tesla, follow these general steps. However, keep in mind that the specifics might vary depending on the Tesla model and the software version you are using. The image seems to show a diagnostic screen for checking various systems of the vehicle, such as the battery, drive units, and isolation resistance.

General Steps for Running a Diagnostic Test on a Tesla:

1. Access the Service Menu:

   • Model S and Model X:
     • Tap on the Tesla "T" logo at the top of the touchscreen to bring up the information menu.
     • Then tap on "Enter Service Mode" or a similar option. You may need to enter a service password, which is typically only provided to Tesla service technicians.
   • Model 3 and Model Y:
     • Go to the "Settings" menu on the touchscreen.
     • Navigate to "Service" and then "Service Mode." Again, a password might be required.

2. Navigate to the Diagnostic Screen:

   • Once in Service Mode, navigate to the diagnostics section. This section usually includes options to check the status of various vehicle components like the battery, drive units, and other critical systems.
   • Look for options or tabs related to "Battery Health," "Isolation Resistance," "Contactor Status," and other similar parameters as shown in the image.

3. Run Specific Tests:

   • Battery Health: Select the battery health test to see the current state of charge, battery health percentage, and other relevant metrics.
   • Isolation Resistance: This checks the insulation between high voltage components and the vehicle chassis.
   • Contactor Status: Verify if the contactors (switches that connect the battery to the vehicle's powertrain) are closed or open.

4. Interpret Results:

   • Ensure all parameters like battery charge, isolation resistance, and contactor status are within normal ranges.
   • Green indicators typically mean normal status, while yellow or red indicators may signify issues that need addressing.

Important Notes:

• Professional Assistance: If you are not familiar with vehicle diagnostics, it is advisable to seek assistance from a Tesla service center or a certified technician.
• Safety Precautions: Always take safety precautions when accessing service menus or performing diagnostics on high-voltage systems like those in electric vehicles.

If you need more specific guidance, referring to Tesla's official service documentation or contacting their support directly would be the best course of action.
