POWER STEERING SYSTEM, Diagnostic DTC:C1516

DTC Code DTC Name
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.

  • Torque sensor zero point calibration failure

  • Steering column sub-assembly

CAUTION / NOTICE / HINT

Note

If the power steering ECU assembly, steering column sub-assembly or power steering motor assembly has been replaced, perform the torque sensor zero point calibration and assist map writing Click here.

PROCEDURE

      DTC is still output even after performing torque sensor zero point calibration 3 times*1. A
      DTC is still output even after performing torque sensor zero point calibration once or twice*2. B
      Normal system code is output. C

      Tech Tips


      • *1: The power steering ECU assembly must be replaced if DTC C1516 is still output even after the torque sensor zero point calibration is performed 3 times.

      • *2: Perform the torque sensor zero point calibration again if DTC C1516 is still output even after the calibration is performed once or twice.
