PROCEDURE


  1. CHECK RELATED PART


    1. Confirm if the related part has the correct part number.

      Related Part ECM
      Steering sensor
      VGRS ECU (front steering control ECU)*
      Skid control ECU (brake actuator assembly)

      • *: w/ Variable Gear Ratio Steering System

      Note

      When removing the related part to check it, be sure to follow the appropriate procedures and precautions.


      Result
      Result Proceed to
      The related part has the correct part number A
      The related part has an incorrect part number B

  2. CHECK FOR DTC


    1. Select Health Check on the GTS screen and check if system DTCs of the related part are output.

      Tech Tips

      If system DTCs of the related part are stored, assist map writing to the power steering ECU (rack and pinion power steering gear assembly) may not be performed properly.

      Result
      Result Proceed to
      System DTCs of the related part are output A
      System DTCs of the related part are not output B
