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 assembly stores these DTCs when it determines that the rotation angle sensor value initialization and torque sensor zero point calibration have not been performed.

DTC Code DTC Detection Condition Trouble Area
C1515 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 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.

CAUTION / NOTICE / HINT

Note

If the power steering ECU assembly or steering column assembly is replaced, perform 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 and calibrate the torque sensor zero point Click here.


    NEXT

  2. CHECK FOR DTC


    1. Check for DTCs Click here.

      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, check the procedure again, and perform calibration and initialization 3 times.

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