On-Board System Readiness Test Mode: Description

WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2002 Lincoln Town Car, 2002 Lincoln Navigator, 2002 Lincoln LS, 2002 Lincoln Continental, and 2002 Lincoln Blackwood. However, it is still accessible from the selected car via links, so may be relevant.

All OBD-II scan tools should be able to display OSR test. The OSR will display monitors on the vehicle and status of all monitors; complete or not complete. If not complete, the scan tool will display which monitor has not completed. Comprehensive component, fuel and misfire monitors run continuously and will always display YES. Only a PCM reset, or keep alive RAM reset will cause non-continuous monitors to reinitialize to display NO.
