DTC C1516 Torque Sensor Zero Point Adjustment Incomplete


DESCRIPTION

This DTC does not indicate a malfunction. The power steering ECU assembly outputs this DTC when it determines that the torque sensor zero point calibration has not been completed successfully.

DTC No.
DTC Detection Condition
Trouble Area
C1516
Torque sensor zero point calibration not completed successfully.
  1. Torque sensor zero point calibration failure
  2. Steering column assembly

INSPECTION PROCEDURE

NOTICE:
If the power steering ECU assembly, steering column assembly or power steering motor assembly has been replaced, perform the torque sensor zero point calibration and assist map writing (YARIS_NCP93 RM000000OSZ018X.html).
1.CLEAR DTC

  1. Clear the DTCs (YARIS_NCP93 RM000001AL601KX.html).

2.PERFORM ZERO POINT CALIBRATION (TORQUE SENSOR)

  1. Perform torque sensor zero point calibration (YARIS_NCP93 RM000000OSZ018X.html ).


NEXT


3.CONFIRM DTC

  1. Check for DTCs (YARIS_NCP93 RM000001AL601KX.html).

    Result
