DTC C1516: Torque Sensor Zero Point Adjustment Incomplete; DTC C1526: Rotation Angle Sensor Initialization Incomplete: Procedure

1. Clear the DTCs. Refer toDTC CHECK / CLEAR .

NEXT: Go to next step 

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

NEXT: Go to next step 

1. Check for DTCs. Refer toDTC 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 once or twice*2.	B
   Normal system code is output.	C

   HINT: 

   • *1: The power steering ECU must be replaced if DTC C1516 or C1526 is still output even after the rotation angle sensor value initialization and torque sensor zero point calibration is performed 3 times.
   • *2: Perform the rotation angle sensor value initialization and torque sensor zero point calibration again if DTC C1516 or C1526 is still output even after the rotation angle sensor value initialization and calibration is performed once or twice.

C → END 

B → See step   9 

A: Go to next step 

1. Replace the power steering ECU. Refer toREMOVAL .

NEXT: Go to next step

   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 twice*2.	B
   Normal system code is output.	C

   HINT: 

   • *1: The steering column assembly must be replaced if DTC C1516 or C1526 is still output even after the rotation angle sensor value initialization and torque sensor zero point calibration is performed 3 times.
   • *2: Perform the rotation angle sensor value initialization and torque sensor zero point calibration again if DTC C1516 or C1526 is still output even after the rotation angle sensor value initialization and calibration is performed twice.
   NOTE:

   If replacing the steering column assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate the torque sensor zero point. Refer toCALIBRATION .
