Help!!!
I was out cruising to a client's site from my office today in my 2000 coupe when all heck broke loose. I started getting error messages in the DIC and the Check Engine and other lights came on. I pulled over as soon as I could and started copying down DTCs. With the number of codes (gotta be 40 or so) and the percentage of them that start with "U" (most), I'm guessing it has to be something electrical or computer-related.
The right-side door is completely unresponsive-- the window won't budge, the door lock switch won't work, the mirror doesn't move. The left door is doing some of the same, but not all the time. I was able to roll the right window up all the way and drive for a few hundred feet without errors to a gas station after clearing all the DTCs. One other thing I noticed is that I had started to roll up my windows (had them down to aid the A/C in getting rid of the hot air built up) when the right one stopped on its own about an inch from the top, and then I got all of the errors. Some of the error messages in the DIC are:
CHECK TIRE PRESSURE
SERV. TIRE MON. SYS
SHOCKS INOPERATIVE
REDUCED ENGINE POWER
SERVICE VEHICLE SOON
SERVICE ACTIVE HANDLING
LOW FUEL
Here is the list of DTCs:

Some details about the car: It's a 6spd coupe with most of the available options: Active Handling, Selective Real-Time Damping, HUD, memory package. It just turned 70000 miles (and apparently decided to pout rather than celebrate!). I washed it on Saturday, but didn't get any excessive water under the hood or inside, and was able to drive it with no trouble Saturday night. Since I got it nearly a year ago, the seat movement with memory settings has been dodgy-- I usually have to manually scoot up the last little bit (I believe that's where the SCM B2187 comes from).
Does anyone know where I should start here? c4c5, seen this one before? I'm going to start looking through my service manuals, but if anybody has any thoughts or experiences with this, I'd be most grateful if you'd share.
Thanks,
Fred
