Apple Diagnostics for Self Service Repair

To help isolate the cause of an issue on a device you’re troubleshooting, you may be prompted to use Apple Diagnostics for Self Service Repair or Apple Diagnostics for Repair diagnostic test suites. A diagnostic suite consists of multiple diagnostic tests. Running these test suites can help isolate issues, investigate whether a part needs to be replaced, and verify that a repair has been successfully completed.

Diagnostic choices

Apple Diagnostics for Repair refers to running diagnostic test suites directly on the device being tested. Apple Diagnostics for Self Service Repair refers to running diagnostic test suites over the web using a secondary device. Both methods provide the same set of diagnostic test suites.

Apple Diagnostics for Repair

Running Apple Diagnostics for Repair directly on the device being tested is the easiest way to run diagnostic test suites if the device meets the requirements to do so. The device uses its built-in display as a diagnostic console to select, run, and display test suites and results.

Apple Diagnostics for Self Service Repair

If your device doesn’t meet the requirements for Apple Diagnostics for Repair, has issues that prevent you from using the display, or if you otherwise can't use Apple Diagnostics for Repair, you can access these same suites online using a secondary device using Apple Diagnostics for Self Service Repair. To access the test suites online, you'll need a separate, secondary device with a web browser and internet access. The second device serves as a diagnostic console, where you’ll enter the serial number of the device that you’re servicing.

You’ll select the recommended diagnostic test suite on the secondary device. When the diagnostic test has finished running, results will appear on the diagnostic console on the secondary device. Examine the results to help isolate the cause of the issue on the device being tested.
