Unable to launch Apple Diagnostics

I encountered a (recoverable) kernel panic on my MBP this morning when waking my system after upgrading to Mojave from ElCapitan just a few days earlier. In order to figure out if there may be hardware issues I attempted a restart while holding the D key in order to launch Apple Diagnostics. I however was greeted by this error message:


Error: 0x8000000000000003, Cannot Load 'EFI/Drivers/TestSupport.efi'

Status: 0x00000003


I am able to restart and launch OS X - thus the system is operational. But obviously something strange is going on.


Question: IF I create a bootable drive will I be able to launch diagnostics or AHT from there?


Thanks in advance.

MacBook Pro 15", macOS 10.14
