On-Board System Readiness (OSR)

On-Board System Readiness (OSR)

Description
All on board diagnostic (OBD) scan tools display the on-board system readiness (OSR) test. The OSR displays the supported monitors on the vehicle and the status of all monitors (complete or not complete) at that time. Fuel, misfire, and comprehensive component monitors run continuously and always display YES status. Clearing the continuous DTCs and resetting the emission monitors information in the PCM, or resetting the keep alive memory (KAM) causes the non-continuous monitors to change to a NO status.

A detailed description of completing the OBD monitors is found.
