Consult the [reference codes](http://support.apple.com/en-us/HT203747) to interpret the results. If however, you reinstalled an older computer from scratch, the diagnostic tools might no longer be available. Unless you have the original disks that came with your computer, there seems to be no way to restore the AHT.
