To reset the steering angle, you need to first find the relative zero point
position for the car to drive in a straight line. Taking this position as a
reference, the ECU can calculate the accurate angle for left and right steering.
After replacing the steering angle position sensor, replacing steering
mechanical parts (such as steering gearbox, steering column, end tie rod,
steering knuckle), performing four-wheel alignment, or recovering the car
body, you must reset the steering angle.
