  2. Steering column assembly

INSPECTION PROCEDURE

1.PERFORM ZERO POINT CALIBRATION (TORQUE SENSOR)

NEXT


2.CONFIRM DTC

  1. Check for DTCs (YARIS_NCP93 RM000001AL601EX.html ).

    Result:

    DTC still output even after performing torque sensor zero point calibration 3 times.
    		A
    DTC still output even after performing torque sensor zero point calibration once or twice.
    		B
    Normal system code output.
    		C
    HINT:
    The steering column assembly must be replaced if C1515/15 is still output even after the torque sensor zero point calibration is performed 3 times.
