C1516

POWER STEERING: POWER STEERING SYSTEM: C1516: 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
NOTE: If the steering column or power steering ECU has been replaced, perform the rotation angle sensor initialization and torque sensor zero point calibration .

PROCEDURE

1. CLEAR DTC
(a) Clear the DTCs .
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 .
NEXT -- Continue to next step.
3. RECONFIRM DTC
(a) Check for DTCs .
Result:






B -- END
A -- Continue to next step.
4. CLEAR DTC
(a) Clear the DTCs .
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 .
NEXT -- Continue to next step.
6. RECONFIRM DTC
(a) Check for DTCs .
Result:






B -- END
A -- Continue to next step.
7. CLEAR DTC
(a) Clear the DTCs .
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 .
NEXT -- Continue to next step.
9. RECONFIRM DTC
(a) Check for DTCs .
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 .
NEXT -- Continue to next step.
11. CLEAR DTC
(a) Clear the DTCs .
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 .
NEXT -- Continue to next step.
13. RECONFIRM DTC
(a) Check for DTCs .
Result:






B -- END
A -- Continue to next step.
14. CLEAR DTC
(a) Clear the DTCs .
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 .
NEXT -- Continue to next step.
16. RECONFIRM DTC
(a) Check for DTCs .
Result:






B -- END
A -- Continue to next step.
17. CLEAR DTC
(a) Clear the DTCs .
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 .
NEXT -- Continue to next step.
19. RECONFIRM DTC
(a) Check for DTCs .
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.
NOTE: 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 .
