Power Steering Control Module

The Power Steering Control Module (PSCM) changes the steering maps for the Terrain Response® program selected. This will change the active steering (self-centering) and active damping functions of the steering system when compared to special programs off. For example, in sand program the steering will exhibit greater self-centering torque to overcome the increased drag when driving in deep soft sand. This is to reduce the overall driving efforts and provide improved road-wheel feedback characteristics when used in such conditions.
