DTC    C1526    Rotation Angle Sensor Initialization Incomplete

for Preparation Click here


DESCRIPTION

These DTCs do not indicate a malfunction. The power steering ECU assembly outputs these DTCs when it determines that rotation angle sensor value initialization and torque sensor zero point calibration are incomplete.

DTC No.
DTC Detection Condition
Trouble Area
C1516
Torque sensor 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 value 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 value initialization.

INSPECTION PROCEDURE

NOTICE:
If the steering column assembly or power steering ECU assembly has been replaced, perform rotation angle sensor value initialization and torque sensor zero point calibration (Click here).

1.CHECK FOR DTC

  1. Clear the DTCs (step 1) (Click here).

  1. Initialize the rotation angle sensor value and calibrate the torque sensor zero point (step 2) (Click here).

  1. Check for DTCs (step 3) (Click here).

    HINT:
    If DTCs are output, perform steps 1 to 3 two more times.

    Result:
    Condition
    		Proceed to
    DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times.
    		A
    Normal system code is output.
    		B
