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 assembly outputs these DTCs when it determines that rotation angle sensor value initialization and torque sensor zero point calibration have not been performed. When IG terminal voltage is 9 V or less rotation angle sensor initialization and torque sensor zero point calibration cannot be performed.
