If you've re-set the light and it keeps coming on, it means that

the computer is still throwing codes, as they say. Take it to

AutoZone or Checker or the like, and have them read the code that's

being thrown and tell you what they mean. Evidently, something is

amiss and needs attention. FriPilot
