Run AHT from bootable USB stick
You need a bootable USB stick, for instance using Disk Utility's Erase with Format: OS X Extended and Scheme: GUID Partition Map.
Let's assume the USB stick is mounted under /Volumes/USBstick.
Download the AHT for your computer model from the list below.
Mount the AHT dmg. Let's refer to the mount point as /Volumes/AHT.
Copy the AHT to the USB stick and flag it as bootable
