If I remember right, it's activated after 30 seconds of the Hydraulic pack operation and a failure to unlock the Uplocks.

Look, it's PPRUNE, not amendments to QRH or FCTM!! Just sharing experiences.
But you are right. We have now become 'people of the book".
The preface to the QRH, explicitly warns pilots, not to use Maintenance level knowledge to trouble shoot. Interestingly, it also goes on to say further, that if at the end of the non normal check list, if the situation is undesirable, one may use such knowledge. But do'nt expect any kudos.

Sorry, wasn't intending to be critical - just point out that it would be difficult to fault the FedEx crew for failing to check STATUS since there is no procedure that would have advised them to do so.
I have no issue with a crew - seeing something unusual - checking STATUS to help figure out what's going on. It occasionally came in handy when troubleshooting something particularly tricky or obscure when the flight crew told us that after something happened, they checked STATUS and saw message XYZ...
I suspect the warning to not use Maintenance knowledge to troubleshoot traces back to the Alaska MD-80 that crashed off LA when the jackscrew stripped. There is a strong belief that if the crew had simply diverted and landed at LAX - instead of trying to troubleshoot the issue so they could continue on to Seattle - it wouldn't have ended in tears.
