C1516

POWER ASSIST SYSTEMS: POWER STEERING SYSTEM: C1515, C1516: Torque Sensor Zero Point Adjustment Undone
C1516 - Torque Sensor Zero Point Adjustment Incomplete

DESCRIPTION

These DTCs do not indicate a malfunction. The power steering ECU stores these DTCs when it determines that the rotation angle sensor value initialization and torque sensor zero point calibration have not been performed.





INSPECTION PROCEDURE

NOTICE:
If the power steering ECU and steering column assembly have been replaced, perform rotation angle sensor initialization and torque sensor zero point calibration Programming and Relearning.

PROCEDURE

1. CHECK FOR DTC

(a) Check if DTC C1516 is output Reading and Clearing Diagnostic Trouble Codes.

Result:





B -- INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
A -- Continue to next step.

2. CLEAR DTC

(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

NEXT -- Continue to next step.

3. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT

(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point Programming and Relearning.

NEXT -- Continue to next step.

4. CHECK FOR DTC

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

Result:





NOTICE:
If DTC C1515 or C1516 is output even though the torque sensor zero point calibration has been performed, confirm the procedure again and perform calibration 3 times.

B -- END

A -- GO TO DTCS C1511 TO C1514 AND DTC C1517 C1511
