C1525

POWER ASSIST SYSTEMS: POWER STEERING SYSTEM: C1515, C1525; Torque Sensor Zero Point Adjustment Undone; 2013 MY FR-S [03/2012 -]
C1515 - Torque Sensor Zero Point Adjustment Undone
C1525 - Rotation Angle Sensor Initialization Undone

DESCRIPTION

These DTCs do not indicate a malfunction. The power steering ECU assembly stores 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 power steering ECU assembly or steering column assembly is replaced, perform 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 and calibrate the torque sensor zero point Programming and Relearning.

NEXT -- Continue to next step.

2. CHECK FOR DTC

(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.

NOTICE:
If DTC C1515 or C1525 is output even though the rotation angle sensor value initialization and torque sensor zero point calibration have been performed, check the procedure again, and perform calibration and initialization 3 times.

Result

B -- END
A -- Continue to next step.

3. REPLACE POWER STEERING ECU ASSEMBLY

(a) Replace the power steering ECU assembly Removal.

NEXT -- Continue to next step.

4. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT

(a) Initialize the rotation angle sensor and calibrate the torque sensor zero point Programming and Relearning.

NEXT -- Continue to next step.

5. CHECK FOR DTC

(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.

NOTICE:
If DTC C1515 or C1525 is output even though the rotation angle sensor value initialization and torque sensor zero point calibration have been performed, check the procedure again, and perform calibration and initialization 3 times.

Result

B -- END

A -- REPLACE STEERING COLUMN ASSEMBLY Removal
