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 assembly stores this DTC when it determines that torque sensor zero point calibration has not been performed.

DTC No. DTC Detection Condition Trouble Area
C1515 This DTC is stored when torque sensor zero point calibration has not been performed. There is no malfunction if this DTC is not output again after performing zero point calibration.

INSPECTION PROCEDURE

Note


  • If the electric power steering column sub-assembly has been replaced with a new one, perform torque sensor zero point calibration Click here.

  • If the power steering ECU assembly has been replaced with a new one, perform assist map writing and torque sensor zero point calibration Click here.

PROCEDURE


  1. CHECK FOR DTC


    1. Calibrate the torque sensor zero point (step 1) Click here.

    2. Check for DTCs (step 2) Click here.

      Tech Tips

      If DTCs are output, perform steps 1 and 2 two more times.
