DTC C1515: Torque Sensor Zero Point Adjustment Undone; DTC C1525 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.
DTC DETECTION CONDITION CHART
| DTC No. | DTC Detection Condition | Procedure |
|---|---|---|
| C1515 | This DTC is detected when 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 | This DTC is detected when 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 |
