On Board System Readiness (OSR) Test: Description
WARNING: This page is about a different car, the 2009 Ford RV Cutaway, 2009 Ford Econoline, 2009 Ford E450 Super Duty, and 2009 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
All on board diagnostic (OBD) scan tools should display the OSR Test. The OSR displays the supported monitors on the vehicle, the status of all monitors (complete or not complete), and the malfunction indicator lamp (MIL) status. If a monitor is not complete, the scan tool does not identify the monitor that has not completed. Readiness is reported based on the completeness of the comprehensive component monitors (CCM) and the misfire monitor and the exhaust gas recirculation (EGR) monitor. These monitors must be complete before readiness can be cleared.
