DESCRIPTION
This DTC does not indicate a malfunction. The power steering ECU (rack and pinion power steering gear 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. | Torque sensor zero point calibration | EPS warning light: Comes on | The DTC is cleared | 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
NOTICE:
If the rack and pinion power steering gear assembly has been replaced, perform assist map writing and torque sensor zero point calibration.
