Steering: Description and Operation

RSS/SSS DESCRIPTION
The Road Sensing Suspension (RSS or RTD) system controls damping forces in the shock absorbers and struts in response to various road and driving conditions. The system is capable of making these changes within 10-15 milliseconds.

The RSS module receives inputs from sensors to determine vehicle acceleration, wheel to body position, vehicle speed and lift/dive. Vehicle speed and lift/dive are inputs received from the Powertrain Control Module.

The system also controls the Speed Sensitive Steering (SSS) system and the Electronic Level Control (ELC) system. The SSS system changes driver steering effort based on vehicle speed. The ELC system maintains proper vehicle trim height under various loading conditions.
