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 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 stored when torque sensor zero point calibration has not been performed. There is no malfunction if this DTC is not output again after performing zero point calibration.
C1525 This DTC is stored 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.

CAUTION / NOTICE / HINT

Note

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

PROCEDURE


  1. CHECK FOR DTC


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

    2. Check for DTCs (step 2) Click here.

      Tech Tips

      If DTCs are output, perform steps 1 and 2 two more times.

      Result
      Condition Proceed to
      DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times. A
      Normal system code is output. B

  3. CHECK FOR DTC


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

    2. Check for DTCs (step 2) Click here.

      Tech Tips

      If DTCs are output, perform steps 1 and 2 two more times.

      Result
      Condition Proceed to
      DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times. A
      Normal system code is output. B

      Note

      If replacing the steering column assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate the torque sensor zero point Click here.
