POWER STEERING SYSTEM, Diagnostic DTC:C1515, C1525

DTC Code DTC Name
C1515 Torque Sensor Zero Point Adjustment Undone
C1525 Rotation Angle Sensor Initialization Undone

DESCRIPTION

These DTCs do not indicate a malfunction. The power steering ECU stores these DTCs when it determines that the rotation angle sensor value initialization and torque sensor zero point calibration have not been performed.

DTC No. DTC Detection Condition Trouble Area
C1515 This DTC is detected when torque sensor zero point calibration has not been performed. There is no malfunction if this DTC is not output again after performing torque sensor zero point calibration.
C1525 This DTC is detected when rotation angle sensor value initialization has not been performed. There is no malfunction if this DTC is not output again after performing rotation angle sensor value initialization.

INSPECTION PROCEDURE

Note

If the power steering ECU and steering column assembly have been replaced, perform the rotation angle sensor initialization and torque sensor zero point calibration Click here.

PROCEDURE


  1. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT


    1. Initialize the rotation angle sensor value and calibrate the torque sensor zero point Click here.


    NEXT

  2. CHECK FOR DTC


    1. Check for DTCs Click here.

      Result
      Condition Proceed to
      DTC C1515 or C1525 is still output after performing rotation angle sensor value initialization and torque sensor zero point calibration 3 times. A
      DTC C1515 or C1525 is not output. B

      Note

      If DTC C1515 or C1525 is output even though the rotation angle sensor value initialization and torque sensor zero point calibration have been performed, confirm the procedure again, and perform the calibration and initialization 3 times.

      Tech Tips

      Replace the power steering ECU if DTC C1515 or C1525 is still output after performing rotation angle sensor value initialization and torque sensor zero point calibration 3 times.

      Result
      Condition Proceed to
      DTC C1515 or C1525 is still output after performing rotation angle sensor value initialization and torque sensor zero point calibration 3 times. A
      DTC C1515 or C1525 is not output. B

      Note

      If DTC C1515 or C1525 is output even though the rotation angle sensor value initialization and torque sensor zero point calibration have been performed, confirm the procedure again, and perform the calibration and initialization 3 times.

      Tech Tips

      Replace the steering column assembly if DTC C1515 or C1525 is still output after performing rotation angle sensor value initialization and torque sensor zero point calibration 3 times.
