Toyota Repair: power steering

Question
I have a Lexus IS250 2006 The power steering light is on so there is no power steering please advise.

Answer
This model uses computer controlled electric power steering, due to the complexity of the system and that there could be a number of things that cause the light to turn on you would have to contact a Toyota or Lexus dealer that will connect a diagnostic computer to retrieve trouble codes in the steering system.
