DTC C1525, C1526: Rotation Angle Sensor Initialization Undone; Rotation Angle Sensor Initialization Incomplete: Description

These DTCs do not indicate a malfunction. The power steering ECU stores these DTCs when it determines that the rotation angle sensor value initialization and torque sensor zero point calibration have not been performed.

DTC Code DTC Detection Condition Trouble Area
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.
C1526 Rotation angle sensor value initialization is incomplete due to the steering wheel being touched during calibration. There is no malfunction if this DTC is not output again after clearing the DTCs and torque sensor calibration value, and performing rotation angle sensor value initialization.
