DTC C1518 Torque sensor calibration not completed
 
 
 
 
OPERATION
By executing the calibration of the torque sensor, the EPS-ECU learns the neutral position of the torque sensor.
 
 
 
FUNCTION
If torque sensor calibration is not performed, sets this DTC.
 
 
 
TROUBLE JUDGMENT
Check Conditions
  • Turn the ignition switch to the "ON" position.
Judgment Criterion
  • When torque sensor calibration is incomplete.
Fail Safe, Back Up Function
  • The EPS-ECU turns on the electric power steering warning lamp, and sets diagnostic trouble code No.C1518.
  • Even if torque sensor calibration is not executed, assist is performed, but there may be a difference in assisting force when steering wheel is rotated left and right. This can be solved by correctly completing torque sensor calibration.
 
 
 
TROUBLESHOOTING HINTS
  • Torque sensor calibrations incomplete.
 
 
 
 
DIAGNOSIS
Perform torque sensor calibration (Refer to ).
