A friend of mine bought an update for his OTC scanner for these systems you might need a scanner to do this.
http://www.ntxtools.com/ sells various scanners the cheapest was $38.00. This only will pickup and delete codes.
Ask Auto Zone or Advance if their scanner will shut off this light. My friends was around $3900 but he bought a top line model for all cars. Look at OTC scanners.
