•  For system simplification, the steering angle sensor has been eliminated and the auto-learning function has been adopted. The steering angle sensor is still used on vehicles with AFS (APTIVE FRONT LIGHTING SYSTEM), SCBS (SMART CITY BRAKE SUPPORT), and park assist system.

•  The EPS control module performs the steering angle learning every drive cycle.

•  No special operation or service is required because the steering angle learning is performed automatically while driving.

•  The system may learn the wrong steering angle temporarily even if the system is normal. In this case, switch the ignition off and leave the vehicle in this condition for approx. 5 minutes, and the steering angle will be re-learned on the next drive cycle.

•  The steering angle may be difficult to learn if the road surface is in poor condition (gravel road, bumps and potholes), even if the system is operating normally. Snow covered roads and brick-laid roads are possible.

•  The steering angle information output from the EPAS, which is read out by the M-MDS, is the relative steering angle. Therefore, when the steering wheel is in the straight-ahead position so as to set the steering wheel angle to 0 degrees when the ignition is switched ON, a value indicating that the steering angle is not 0 degrees may occur.

•  If a user makes a claim that the steering force required for left and right turns is different, the steering angle may not have been learned correctly. Stop the engine, and the steering angle we be re-learned on the next drive cycle.
