4. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point See: Steering and Suspension/Steering/Testing
and Inspection/Programming and Relearning.
NEXT -- Continue to next step.
5. CHECK FOR DTC
(a) Check for DTCs See: Steering and Suspension/Steering/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes.
Result:
NOTICE:
If DTC C1515 or C1525 is output even though the rotation angle sensor value initialization and torque sensor zero point
calibration have been performed, confirm the procedure again, and perform the calibration and initialization 3 times.
HINT
Replace the steering column assembly if DTC C1515 or C1525 is still output after performing rotation angle sensor value
initialization and torque sensor zero point calibration 3 times.

From 08/2009
POWER ASSIST SYSTEMS: POWER STEERING SYSTEM: C1515,C1525: Torque Sensor Zero Point Adjustment Undone
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 the rotation angle sensor initialization and
torque sensor zero point calibration See: Steering and Suspension/Steering/Testing and Inspection/Programming and
Relearning.
PROCEDURE
1. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point See: Steering and Suspension/Steering/Testing
and Inspection/Programming and Relearning.
