Road Sensing Suspension General Description

The Continuously Variable Road Sensing Suspension (CVRSS) system consists of the following components: CVRSS control module (3), four dampers contained in the two front struts (5 and 6) and the two rear shock absorbers (1 and 9), four positions sensors (2,4,7, and 8), ALC air compressor module (10), Damper relay (not shown), and ALC relay (not shown).

The Continuously Variable Road Sensing Suspension (CVRSS) system with rear Automatic Leveling Control (ALC) controls damping forces in the front struts and rear shock absorbers in response to various road and driving conditions. The rear ALC portion of the system maintains a proper vehicle trim height under various vehicle load conditions.

NOTE: The CVRSS control module will remain powered for a short period of time (typically under 5 minutes) after the ignition has been turned off. This system-on period after ignition-off allows the system to level the vehicle and perform other required functions.


The CVRSS control module receives the following inputs: wheel-to-body position, vehicle speed, and lift/dive. The CVRSS control module evaluates these inputs and controls actuators in each of the dampers independently to provide varied levels of suspension control.
