2003 Chevy Avalanche oil change reset

Hi: Try this first and let me know if it works.

1) get in the car and close the door.

2) turn the key to the run position (DO NOT START)

3) press the gas pedal to the floor 3 times

4) wait a few seconds for the light to flash or you may hear a ding.

5) once that has occurred, turn the key off and start the engine to see if it reset.

Let me know if this helps. If not, there is a sequence through the radio. But I don't think that started until 05.
