check engine light

I've a 1995 S420 that the "check engine" light has come on. This happened less than 300 miles after it passed smog. Is there a way to reset it and see if the problen is still there? (That is the light comes on again), and/or someway for me to either narrow down what the problem is or pinpoint the problem?
All the owners handbook says is that it's either a problem in the fuel injection system or smog equipment. The car runs as it always has.
