There are fuses for the PCM , but if that is out I don't think it would start , one fuse box is under the hood driver's side [PCM fuses (there is just one PCM , but 2 fuses for it ) 1 and 2 , fuse #10 and #28] , and the other is under the rear seat passenger side [TCM looks to be fuse #35] .
Erik , is the resident older TB tech .
If you have EFILive it will scan for DTCs as well .

So what was the problem? If its really technical and more related to your TB in general (not exclusively to PCM tuning) Id recommend heading to TrailVoy.com and posting there. Lots of TB owners get a lot of info from there including myself.

If not I hope your TB gets fixed up and running strong! Ive got 109,5xx mi on my 02 and no major issues so far (knock on wood). Hope my parents dont sell it within the year, that'd be one sad Erik. :(

Sounds like he had a blown fuse Erik .
Glad it worked out for you , what was the DTC that was causing the MIL ?
Yeah TrailVoy.com is a good website for the TB .
