MIL Control Circuit trouble shooting

Does anyone have any ideas on how to trouble shoot the MIL Control circuit? Code is P1671
I did a 98 3.8 s.c engine swap from a 98 GP GTP to a 02 GP SE that had a 3.1.
I am using the 98 pcm.
When i plug in my scanner i can go to output controls and select turn on MIL light, it does not illuminate. when i first turn the ignition on to run, the indicator does illuminate.
 


Thats an interesting artical.
I also forgot to mention that i did the digital dic swap, and that the oil change light indicator was in the analog but now its in the digital in oil life.
 
Well i picked up a 2000 gtp fuse/relay box assembly to go along with the 2000 pcm, pcm engine harness, and bcm, now ALL of the indicator lights work the way they are supposed to now.
