C1526

POWER STEERING: ELECTRONIC 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 rotation angle sensor initialization and torque sensor zero point calibration are incomplete.






INSPECTION PROCEDURE

PROCEDURE

1. CLEAR DTC
NEXT -- Continue to next step.
2. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor and calibrate the torque sensor zero point Electronic Power Steering System

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






C -- END
B -- INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
A -- Continue to next step.
4. REPLACE POWER STEERING ECU
NEXT -- Continue to next step.
5. CLEAR DTC
NEXT -- Continue to next step.
6. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor and calibrate the torque sensor zero point Electronic Power Steering System.
NEXT -- Continue to next step.
7. RECONFIRM DTC
(a) Check for DTCs.
Result:





NOTICE:
- 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 Electronic Power Steering System.
- If replacing the power steering link assembly, perform VGRS actuator angle initialization Programming and Relearning and VGRS actuator angle neutral calibration Variable Gear Ratio Steering System after wheel alignment adjustment.

C -- END
B -- INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
A -- REPLACE POWER STEERING LINK ASSEMBLY
