Service function guideSteering Angle Sensor Calibration

This workshop guide covers the complete process of calibrating a steering angle sensor (SAS) after wheel alignment, steering rack replacement, or any procedure that disturbs the steering column or suspension geometry. It explains how the sensor communicates with the electronic stability control (ESC) system, why a zero-point reset is critical for accurate driver-assist and stability functions, and how to prepare the vehicle and workspace for a reliable calibration. You will learn the step-by-step service function procedure, how to verify success with scan-tool data and a road test, and how to troubleshoot common failures across different vehicle architectures. By the end, you will be able to perform a professional SAS calibration, confirm the result, and advise the customer on aftercare.
