CEL light came on friday night. Had just put in some fog lights and hardwired them to the battery. Didn't move or touch anything else in the engine bay. It didn't come on right away, I was going from a friends to home... about 4-5miles. It was snowing pretty heavily and very icy, so I was going very slow. It's an auto so I have D4 D3 2 and 1 for gearing choices. Most of the time I had it in D3 for the ride home... about 3 times I dropped to 2 for about 5 seconds and once dropped to 1 for abour 10 seconds. RPM's weren't really high, never past redline.

First noticed the CEL about 1/8th mile from my place. Everything seems to be running fine. Any idea if it came on because of the gearing I was choosing or if it's something else? It was wet/snowy/icy/freezing... perfect combination for anything to go wrong.

I know that if you short 2 pins... on the ?ECU? that the CEL light will blink the number of times to show the code. Is that right? Can someone give me some more detail on how to see what code it's giving? I'd like to try and fix this myself instead of giving $150 to the local dealer just to have them tell me it was nothing.
