If you are facing power, sensor, or unexpected shutdown issues on these specific models, locating and using ASD 3S159 is the best way to get a definitive answer on your hardware status. If you own a 2013 Mac Pro (the

Technicians tracking A1481 diagnostic anomalies note that specific revisions of the BootROM or display setups can trigger false positives during automated sweeps. As documented on community repair logs like LogiWiki, if your unit hangs or reports immediate failures on or Display Backlight Control Tests , you should manually disable these tests in the ASD interactive options menu before starting a full loop. Interpreting Test Results and Error Codes

Unlike the consumer-facing (initiated by holding the D key at startup), which provides a basic pass/fail result and error codes, ASD is a far more robust and comprehensive tool. Apple Service Diagnostics is designed to run a battery of advanced tests at a low level, checking every major hardware component and subsystem on a Mac.
