DTC C1515, C1525: Torque Sensor Zero Point Adjustment Undone; Rotation Angle Sensor Initialization Undone: Description

These DTCs do not indicate a malfunction. The power steering ECU outputs 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	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	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.
