C1526

POWER ASSIST SYSTEMS: POWER STEERING SYSTEM: C1525, C1526: Rotation Angle Sensor Initialization Undone
C1526 - Rotation Angle Sensor Initialization Incomplete

DESCRIPTION

These DTCs do not indicate a malfunction. The power steering ECU 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 and steering column assembly have been replaced, perform rotation angle sensor initialization and torque sensor zero point calibration Programming and Relearning.

PROCEDURE

1. CHECK FOR DTC

(a) Check if DTC C1526 is output Reading and Clearing Diagnostic Trouble Codes.

Result:





B -- INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
A -- Continue to next step.

2. CLEAR DTC

(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

NEXT -- 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 Programming and Relearning.

NEXT -- Continue to next step.

4. CHECK FOR DTC

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

Result:





NOTICE:
If DTC C1525 or C1526 is output even though the rotation angle sensor value initialization has been performed, confirm the procedure again and perform initialization 3 times.

B -- END

A -- GO TO DTC C1528 C1528
