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 assembly outputs these DTCs when it determines that rotation angle sensor initialization and torque sensor zero point calibration are incomplete.
DTC DETECTING CONDITION AND PROCEDURE
| DTC No. | DTC Detection Condition | Procedure |
|---|---|---|
| C1516 | Steering zero point calibration is incomplete due to the steering wheel being touched during calibration. | There is no malfunction if this DTC is not output again after clearing the DTCs and torque sensor calibration value, and performing zero point calibration. |
| C1526 | Rotation angle sensor initialization is incomplete due to the steering wheel being touched during calibration. | There is no malfunction if this DTC is not output again after clearing the DTCs and torque sensor calibration value, and performing rotation angle sensor initialization. |
- CLEAR DTC
NEXT
- INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
NEXT
- RECONFIRM DTC
- Check for DTCs.
Result
RESULT REFERENCEA DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration 3 times. B DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration once or twice. C Normal system code is output. HINT:
Replace the power steering ECU assembly if DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration 3 times.
B : Go to step 2
C : END
A : GO TO NEXT STEP
- Check for DTCs.
- REPLACE POWER STEERING ECU ASSEMBLY
NEXT
- CLEAR DTC
NEXT
- INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
- Initialize the rotation angle sensor and calibrate the torque sensor zero point (see HOW TO PROCEED WITH TROUBLESHOOTING ).
NEXT
- RECONFIRM DTC
- Check for DTCs.
Result
RESULT REFERENCEA DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration 3 times. B DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration once or twice. C Normal system code is output. HINT:
Replace the power steering link assembly if DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration 3 times.
NOTE:- If replacing the power steering link assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor, and calibrate the torque sensor zero point (see HOW TO PROCEED WITH TROUBLESHOOTING ).
- If replacing the power steering link assembly, perform VGRS actuator angle initialization and VGRS actuator angle neutral calibration after wheel alignment adjustment (see INITIALIZATION and CALIBRATION ).
