DLC Power

(1999 Mercury Cougar)
I attempted to take my vehicle to get my state required emissions testing. I was told the DLC was not getting power and it was likely the cigarette lighter fuse. However, the cigarette lighter still supplies power and its fuse is still functional. What else can cause this? Also, the battery was recently disconnected and re-connected. Can that have any impact on the DLC having power?

I had to same problem with my 2001 Cougar. Turned out to be a blown fuse for the power seats, not the cig lighter.

Are you saying that any blown fuse in the system will prevent the DLC from having power
from its power source. Thanks in advance..
