POWER STEERING SYSTEM, Diagnostic DTC:C1515

DTC Code DTC Name
C1515 Torque Sensor Zero Point Adjustment Undone

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 been performed.

When the IG terminal voltage is below 8 V, torque sensor zero point calibration cannot be performed.

DTC No. Detection Item DTC Detection Condition Trouble Area Warning Indicate Return-to-normal Condition Note
C1515 Torque Sensor Zero Point Adjustment Undone This DTC is stored when torque sensor zero point calibration has not been performed. Torque sensor zero point calibration EPS warning light: Comes on Power switch on (IG) again after performing zero point calibration. There is no malfunction if this DTC is not output again after performing zero point calibration.

CAUTION / NOTICE / HINT

Note


  • If the rack and pinion power steering gear assembly has been replaced, perform assist map writing and torque sensor zero point calibration.
