  • Steering wheel sensor (column switch assembly) replacement, removal, installation
  • ASC-ECU replacement
  1. Update the neutral position stored in the steering wheel sensor.
  2. Reset the calibrated value of the steering angle stored in ASC-ECU.
  • Before performing the calibration, check if the steering wheel sensor-related diagnostic trouble code is set in ASC-ECU.
  • When the diagnostic trouble code other than C121A is set, carry out inspection according to each troubleshooting procedure.

7. Select "SAS Calibration."
8. Select "Special function" under "Steering angle sensor".
note
  • If the steering angle sensor neutral point has been learned, the display will show "If SAS needs re-calibration, execute SAS calibration after executing SAS Initialization". If yes, press "OK" button.
  • At this time, if the steering angle sensor neutral point has been learned, the display will show "Do you want to start? Note This operation will dear DTCs". Then, press "OK" button.
9. The display should show "SAS Calibration: Do you want to start?". Then press the OK button.
notePlease execute after making a tire and a steering wheel straight.
