Check engine light

[WYOMING]

I have a 02 XC70 134,000 and the check engine light just came on. How can I get the light off?

Plug an code reader into the OBD port below the steering wheel (many Auto stores will do this for free), read the code and fix whatever part triggered the code in the first place.
