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 stores this DTC 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
C1516 Torque Sensor Zero Point Adjustment Incomplete Torque sensor zero point calibration is incomplete due to the steering wheel being touched during calibration. - EPS warning light: Comes on Power switch on (IG) again There is no malfunction if this DTC is not output again after clearing the DTC and torque sensor calibration value, and performing zero point calibration.

CAUTION / NOTICE / HINT
