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