The steering angle sensor initialization and steering shaft torque sensor zero point calibration must be performed if any of the following has occurred:
| • | The power steering control module has been replaced. | 
| • | The power steering link has been replaced. | 
| • | Steering effort differs between left and right. | 
Perform the steering angle sensor initialization and steering shaft torque sensor zero point calibration. Refer to Steering Angle Sensor Initialization and Steering Shaft Torque Sensor Zero Point Calibration.
