When do you clear the OBD readiness monitor?
Remember, all on-board diagnostic monitors are cleared when the battery is disconnected, or when the power train control module (PCM) is cleared with a scan tool. Do not turn off the ignition switch during the test procedure. Allow the vehicle to run at idle until warmed up. Drive at a steady speed between 40 and 70 MPH for 10 minutes.
