DTC    C1515    Torque Sensor Zero Point Adjustment Undone


DESCRIPTION

This DTC does not indicate a malfunction. The power steering ECU assembly outputs this DTC when it determines that the torque sensor zero point calibration has not been performed.

DTC No.
DTC Detection Condition
Trouble Area
C1515
Torque sensor zero point calibration not performed.
  1. Torque sensor zero point calibration not performing
  2. Steering column assembly

INSPECTION PROCEDURE

NOTICE:
If the power steering ECU assembly, steering column assembly or power steering motor assembly has been replaced, perform the torque sensor zero point calibration and assist map writing (Click here).
1.PERFORM ZERO POINT CALIBRATION (TORQUE SENSOR)
  1. Perform torque sensor zero point calibration (Click here).

    DTC is still output even after performing torque sensor zero point calibration 3 times*1.
    A
    DTC is still output even after performing torque sensor zero point calibration once or twice*2.
    B
    Normal system code is output.
    C

    HINT:
    1. *1: The power steering ECU assembly must be replaced if DTC C1515 is still output even after the torque sensor zero point calibration is performed 3 times.
    2. *2: Perform the torque sensor zero point calibration again if DTC C1515 is still output even after the calibration is performed once or twice.
