DTC C1515 Torque Sensor Zero Point Adjustment Undone


DESCRIPTION

This DTC does not indicate a malfunction. The power steering ECU stores 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.
There is no malfunction if DTC is not output after performing the torque sensor zero point calibration.

INSPECTION PROCEDURE

NOTICE:
  1. If the power steering ECU has been replaced with a new one, perform the assist map writing and the torque sensor zero point calibration (COROLLA_ZRE142 RM00000275305DX.html).
  2. If the steering column assembly has been replaced with a new one, perform the torque sensor zero point calibration after performing the initialization of the torque sensor zero point value (COROLLA_ZRE142 RM00000275305DX.html).
1.PERFORM ZERO POINT CALIBRATION (TORQUE SENSOR)

  1. Perform the torque sensor zero point calibration (COROLLA_ZRE142 RM00000275305DX.html).

2.CHECK FOR DTC

  1. Check for DTCs (COROLLA_ZRE142 RM00000275005PX.html).

    Result:
    Result
    		Proceed to
    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 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.


B
PERFORM ZERO POINT CALIBRATION AGAIN (TORQUE SENSOR) (COROLLA_ZRE142 RM00000275305DX.html)
