C1515

POWER ASSIST SYSTEMS: POWER STEERING SYSTEM (for 2ZR-FE): 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 stores this DTC when it determines that the torque sensor zero point calibration has not been performed.





INSPECTION PROCEDURE

NOTICE:
* If the power steering ECU has been replaced with a new one, perform the assist map writing and the torque sensor zero point calibration Programming and Relearning.
* If the steering column assembly has been replaced with a new one, perform the torque sensor zero point calibration after performing the initialization of the torque sensor zero point value Programming and Relearning.

PROCEDURE

1. PERFORM ZERO POINT CALIBRATION (TORQUE SENSOR)

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

NEXT -- Continue to next step.

2. CHECK FOR DTC

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

Result:





HINT
* *1: The power steering ECU 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.

C -- END

B -- PERFORM ZERO POINT CALIBRATION AGAIN (TORQUE SENSOR) Programming and Relearning
A -- Continue to next step.

3. REPLACE POWER STEERING ECU

(a) Replace the power steering ECU Removal.

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. CHECK FOR DTC

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

Result:





HINT
* *1: The steering column 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 twice.

C -- END

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

A -- REPLACE STEERING COLUMN ASSEMBLY Removal
