200011C9 — Built-in test failed to complete execution

What 200011C9 means

On CT systems, status code 200011C9 indicates: Built-in test failed to complete execution. The code originates in the Diagnostics / built-in test section of the Diagnostics / built-in test. Severity level warning (Warning — self-test did not complete).

Reported action: Re-run the built-in diagnostic/self-test for the subsystem shown in the 4-digit prefix and check whether it now completes. If it still does not finish, the source itself flags this as either a software or a hardware fault, so inspect that subsystem's hardware and connections before returning the system to clinical use..

From the Philips ultrasound service reference "Error Logger Overview" (New Error Logger), archived under Philips ultrasound End-of-Life service documentation. The source lists this Errno as "Test failed to complete execution - could be software or hardware fault". A full log entry combines a 4-digit Subsystem code with the Errno (format ssss-eeeeeeee, e.g. 0003-200011DA), so this code is the Errno portion only; the source's Errno table is not tied to one specific subsystem. The document does not name a specific system model.
