POWER STEERING SYSTEM(for Power Tilt and Power Telescopic Steering Column), Diagnostic DTC:C1515/15, C1516/16

DTC Code DTC Name
C1515/15 Torque Sensor Zero Point Adjustment is not Initialized
C1516/16 Torque Sensor Zero Point Adjustment Incomplete

DESCRIPTION

These DTCs do not indicate a malfunction.

The power steering ECU assembly stores C1515 when it determines that torque sensor zero point calibration has not been performed.

The power steering ECU assembly stores C1516 when it determines that torque sensor zero point calibration has not completed.

DTC No. Detection Item DTC Detection Condition Trouble Area Warning Indicate Return-to-normal Condition Note
C1515/15 Torque Sensor Zero Point Adjustment is not Initialized This DTC is stored when torque sensor zero point calibration has not been performed. - On Zero point calibration occurs There is no malfunction if this DTC is not output again after performing zero point calibration.
C1516/16 Torque Sensor Zero Point Adjustment Incomplete Torque sensor zero point calibration is incomplete due to the steering wheel being touched during calibration. - On Clear DTC 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.

CAUTION / NOTICE / HINT

Note


  • If the electric power steering column sub-assembly has been replaced, perform torque sensor zero point calibration.
