DTC C1515: Torque Sensor Zero Point Adjustment Undone; DTC C1525: 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

   Result	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
   DTC is not output	C

   HINT: 

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

C → END 

B → See step   1 

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 .

NEXT: Go to next step 

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

   Result

   Result	Proceed to
   DTC is not output	A
   DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times (for w/ VGRS)	B
   DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times (for w/o VGRS)	C
   DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration once or twice	D

   HINT: 

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

   NOTE:

   If replacing the power steering gear assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate the torque sensor zero point. Refer to CALIBRATION .
