Friend has a service light

Ok my firend has an 01 cavy and about a week ago she slid off the road, but didnt really hurt anything to her knowledge. When she got in to start her car the next day the automatic lights didnt come on and when she turns them on they blink for a few seconds and the service light comes on. Anyone have any ideas?

If the service light comes on, you should always find out what it is. AutoZone and a few others give a free diagnostic.
