DTC C1515, C1525: Torque Sensor Zero Point Adjustment Undone; Rotation Angle Sensor Initialization Undone: Procedure

1. Initialize the rotation angle sensor value and calibrate the torque sensor zero point. Refer to CALIBRATION .

NEXT: Go to next step 

1. Check for DTCs. Refer to DTC CHECK/CLEAR .

   Result

   Condition	Proceed to
   DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times*1.	A
   DTCs are still output even after performing rotation angle sensor value initialization and steering zero point calibration 1 or 2 times*2.	B
   Normal system code is output.	C

   HINT: 

   • *1: The power steering ECU must be replaced if DTC C1515 or C1525 is still output even after rotation angle sensor value initialization and torque sensor zero point calibration are performed 3 times.
   • *2: Perform rotation angle sensor value initialization and torque sensor zero point calibration again if DTC C1515 or C1525 is still output even after the calibration is performed 1 or 2 times.

C → END 

B → See step   7 

A: Go to next step 

1. Replace the power steering ECU. Refer to REMOVAL .

NEXT: Go to next step 

1. Initialize the rotation angle sensor value and calibrate the torque sensor zero point. Refer to CALIBRATION .

   DTCs are still output even after performing rotation angle sensor value initialization and steering zero point calibration 2 times*2.	B
   Normal system code is output.	C

   HINT: 

   • *1: The steering column assembly must be replaced if DTC C1515 or C1525 is still output even after rotation angle sensor value initialization and torque sensor zero point calibration are performed 3 times.
   • *2: Perform rotation angle sensor value initialization and torque sensor zero point calibration again if DTC C1515 or C1525 is still output even after the calibration is performed 2 times.
   NOTE: If the steering column is replaced, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate the torque sensor zero point. Refer to CALIBRATION .
