Road test vehicle driving faster than 50 MPH for 20 seconds and avoiding smooth road surfaces. After road test, using scan tool, cycle all CVRSS outputs. Wait 90 seconds. Using Instrument Panel Cluster (IPC) on-board diagnostics, display and record all CVRSS codes and their status (current or history).
