DTC C1515: Torque Sensor Zero Point Adjustment Undone; DTC C1525 Rotation Angle Sensor Initialization Undone: Description
WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.
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.
