You are probably on the right track checking out the IDM. It is in the driver's side fenderwell. You'll need to pull the liner to get to it - at least the back part. Here's how: IDM.pdf
Also, there are reports of the CPS throwing that code, and there are correlations between windshield wiper interference and CPS issues. I don't believe that's your problem given the wipers won't come on at all.
Check your IDM relay - swap it for its neighbor for a trial start.
Also, make sure and check fuses with a multimeter. It sucks to go through ten hours of testing just to find the fuse was blown in the corner where you didn't see it.
Don't forget about the windshield leak issue on the early models - rain runs through the seal and soaks the GEM module - makes for some wierd electrical issues.

I wonder if clouds ever look down on us and say, "Hey, look - that one is shaped like an idiot!"
