On-Board System Readiness (OSR) Test: Description
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2005 Ford RV Cutaway, 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
All on board diagnostic (OBD) diagnostic 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 diagnostic tool will not identify the monitor that has not completed. Readiness for the 6.0L 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.
