Overview

The EPAS system provides steering assist to the driver by replacing the conventional, hydraulic pump system with an electric motor coupled to the steering shaft. The system is controlled by the PSCM which senses the steering effort using sensors mounted between the steering column shaft and the steering gear. Steering assist is provided in proportion to steering effort and vehicle speed.
