I've been playing with the Techstream software tonight, and it seems to do almost anything. Looks like my 600,000 mile extended warranty has run out:
No problem, I'll just turn it back to zero:
And now it looks like my 4WD light is on, which is strange since I don't have 4WD:
I turned off the DRL's, because I always drive with the headlights on anyway. I also changed the defroster to NOT automatically turn on the A/C compressor so I can control it myself. The dealer would charge a lot more than the 30 bucks this package costs--it's a great deal!
