I appreciate the answer, but not the sarcasm. I hyave been playing with this issue for a year. With your advice I did the A trip, then the B trip and then changed the oil change data in the computer. All within 2 or 3 minutes of each other. I had done what you suggested more than once but could never get the light to go off. At any rate your answer prompted me to do the above seversl times and the light is gone. Again, thanks. Guess I was doing something wrong.
