C1526

POWER STEERING: POWER STEERING SYSTEM: C1516,C1526: Torque Sensor Zero Point Adjustment Incomplete

DTC C1516 - Torque Sensor Zero Point Adjustment Incomplete

DTC C1526 - Rotation Angle Sensor Initialization Incomplete

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 are incomplete.






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. CLEAR DTC
(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.
NEXT -- Continue to next step.
2. 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.
3. RECONFIRM DTC
(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
Result:






B -- END
A -- Continue to next step.
4. CLEAR DTC
(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.
NEXT -- 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:






B -- END
A -- Continue to next step.
7. CLEAR DTC
(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.
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 again Programming and Relearning.
NEXT -- Continue to next step.
9. 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.
10. REPLACE POWER STEERING ECU
(a) Replace the power steering ECU Removal.
NEXT -- Continue to next step.
11. CLEAR DTC
(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.
NEXT -- 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 Programming and Relearning.
NEXT -- Continue to next step.
13. RECONFIRM DTC
(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
Result:






B -- END
A -- Continue to next step.
14. CLEAR DTC
(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.
NEXT -- Continue to next step.
15. 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.
16. RECONFIRM DTC
(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
Result:






B -- END
A -- Continue to next step.
17. CLEAR DTC
(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.
NEXT -- Continue to next step.
18. 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.
19. 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.

B -- END
A -- REPLACE STEERING COLUMN
