POWER STEERING: POWER STEERING SYSTEM: C1515,C1525: Torque Sensor Zero Point Adjustment Undone

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 outputs these DTCs when it determines that the rotation angle sensor value initialization and torque sensor zero point calibration have not been performed.






INSPECTION PROCEDURE
NOTICE: If the steering column or power steering ECU has been replaced, perform the rotation angle sensor initialization and torque sensor zero point calibration Programming and Relearning.

PROCEDURE

1. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point Programming and Relearning.
NEXT -- Continue to next step.
2. RECONFIRM DTC
(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
Result:






B -- END
A -- Continue to next step.
3. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point again Programming and Relearning.
NEXT -- Continue to next step.
4. RECONFIRM DTC
(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
Result:






B -- END
A -- Continue to next step.
5. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point again Programming and Relearning.
NEXT -- Continue to next step.
6. RECONFIRM DTC
(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
Result:





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.

B -- END
A -- Continue to next step.
7. REPLACE POWER STEERING ECU
(a) Replace the power steering ECU Removal.
NEXT -- Continue to next step.
8. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point Programming and Relearning.
NEXT -- Continue to next step.
9. RECONFIRM DTC
(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
Result:






B -- END
A -- Continue to next step.
10. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point again Programming and Relearning.
NEXT -- Continue to next step.
11. RECONFIRM DTC
(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
Result:






B -- END
A -- Continue to next step.
12. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point again Programming and Relearning.
NEXT -- Continue to next step.
13. RECONFIRM DTC
(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
Result:





HINT: Replace the steering column if DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times.
NOTICE: If replacing the steering column, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate the torque sensor zero point Programming and Relearning.
