A diagnostic test will not run

Review test availability, instructions, and operating conditions when a diagnostic test will not start.

Check the selected test

Confirm that you are connected to the correct engine. Available tests depend on DTK implementation and support in the connected engine calibration.
Open the selected test's INSTRUCTIONS. Review its initial conditions and required steps.
Confirm the required engine state. Some tests require a running engine; others require Key-on only. Follow the requirements for the selected test.
Review the Status messages for progress or unmet conditions and address the reported condition.
Use the correct start control for your platform. See Run diagnostic tests for Windows and Mobile controls.

Collect the test name, Status messages, DTK version, equipment details, and available logs before contacting support. See Information for support.
