DTC simply means Diagnostic Trouble Code.
As for the LDP, I don't know who is right or wrong. I was following Mitchell On Demand description. After your last post, I pulled out my Chilton manual 20320 and started snooping around. Page 4-8 did say that Sebring and Avenger coupes (off Mitsu Eclipse) do not come with LDP. To check for leaks on these models, you have to use a hand-held vacuum pump attached to the vacuum hose nipple on the throttle body. But at page 4-42, it shows that 96-97 Sebring and Avenger coupes do have LDP on the vacuum diagram. What does your Haynes manual say?
But regardless, just get yourself a hand-held vacuum pump, and start the engine. The vacuum should remain level for 10 seconds. If not, your system leaks.
