C1515 This DTC is detected when torque sensor zero point calibration has not been performed.

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.

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.

INSPECTION PROCEDURE

1. INITIALIZE ROTATION ANGLE SENSOR VALUE AND CALIBRATE TORQUE SENSOR ZERO POINT

1. Initialize the rotation angle sensor value and calibrate the torque sensor zero point (Click here).

NEXT

2. RECONFIRM DTC

1. Check for DTCs (Click here).
   

   Result:

   Condition	Proceed To
   DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times.	A
   DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration once or twice.	B
   Normal system code is output.	C

   HINT:

   Replace the power steering ECU assembly if DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times.

B	Go to step 1
C	END

3. REPLACE POWER STEERING ECU ASSEMBLY

1. Replace the power steering ECU assembly (Click here).

4. INITIALIZE ROTATION ANGLE SENSOR VALUE AND CALIBRATE TORQUE SENSOR ZERO POINT

1. Initialize the rotation angle sensor value and calibrate the torque sensor zero point (Click here).

5. RECONFIRM DTC

1. Check for DTCs (Click here).
   

   Result:

   Condition	Proceed To
   DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times.	A
   DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration once or twice.	B
   Normal system code is output.	C

   HINT:

   Replace the power steering link assembly if DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times.

   NOTICE:

   If replacing the power steering link assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate the torque sensor zero point (Click here)
