SAS CALIBRATION: WHY STEERING ANGLE SENSOR CALIBRATION IS IMPORTANT FOR YOUR VEHICLE

SAS Calibration, also known as Steering Angle Sensor Calibration, is an essential vehicle safety procedure that ensures your car’s steering wheel position is correctly aligned with the vehicle’s ECU. Modern vehicles depend on accurate SAS data to operate ABS, ESP, ESC, ADAS and Traction Control systems, making calibration extremely important after wheel alignment, suspension replacement, steering rack repairs, tyre upgrades or accident correction. When the SAS value is incorrect, drivers experience an off-centre steering wheel, car pulling to one side, unwanted dashboard warning lights, reduced braking stability and poor cornering control. SAS Calibration resets the steering wheel’s zero point electronically, allowing the vehicle to regain balance, directional accuracy and straight-line stability. Workshops carry out SAS calibration using advanced diagnostic scanners like Autel, Bosch, Hunter or OEM scan tools to read live steering data and reset ECU values. Correct SAS data improves steering comfort, enhances tyre life, supports ADAS features, and protects traction control systems from malfunctioning. Ignoring SAS calibration may lead to uneven tyre wear, vibrations at high speed, loss of steering accuracy and reduced safety performance. With factories now manufacturing vehicles equipped with complex technology, SAS Calibration has become just as critical as wheel alignment and suspension maintenance. For vehicle owners noticing steering vibration, pulling issues, ABS or ESP lights, or instability after alignment, SAS Calibration ensures the steering angle sensor and wheel direction are perfectly synchronised, providing safer handling, improved road grip and longer tyre life. In simple words, SAS Calibration protects your vehicle’s steering accuracy, electronic safety systems and everyday driving experience, making it a must-have service for modern cars.
