C1515

POWER ASSIST SYSTEMS: POWER STEERING SYSTEM (for Hatchback): C1515: Torque Sensor Zero Point Adjustment Undone
C1515 - Torque Sensor Zero Point Adjustment Undone

DESCRIPTION

This DTC does not indicate a malfunction. The power steering ECU assembly outputs this DTC when it determines that the torque sensor zero point calibration has not been performed.

INSPECTION PROCEDURE

NOTICE:
If the power steering ECU assembly, steering column assembly or power steering motor assembly has been replaced, perform the torque sensor zero point calibration and assist map writing Programming and Relearning.

PROCEDURE

1. PERFORM ZERO POINT CALIBRATION (TORQUE SENSOR)

(a) Perform torque sensor zero point calibration Programming and Relearning.

NEXT -- Continue to next step.

2. CONFIRM DTC

(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.

Result

HINT
* *1: The power steering ECU assembly must be replaced if DTC C1515 is still output even after the torque sensor zero point calibration is performed 3 times.
* *2: Perform the torque sensor zero point calibration again if DTC C1515 is still output even after the calibration is performed once or twice.

B -- PERFORM ZERO POINT CALIBRATION AGAIN (TORQUE SENSOR) Programming and Relearning

C -- END
A -- Continue to next step.

3. REPLACE POWER STEERING ECU ASSEMBLY

(a) Replace the power steering ECU assembly Removal (from 07/2011).

NEXT -- Continue to next step.

4. PERFORM ZERO POINT CALIBRATION (TORQUE SENSOR)

(a) Perform the torque sensor zero point calibration Programming and Relearning.

NEXT -- Continue to next step.

5. CONFIRM DTC

(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
