System Status and Drive Cycle For Satisfying I/M 240

I/M Ready Status means a signal or flag for each Emission System test that had been set in the [1][2]PCM. I/M Ready Status indicates that the vehicle on-board emissions diagnostics have been run. I/M Ready Status is not concerned whether the Emission System passed or failed the test, only that on-board diagnosis is complete. Not all vehicles use all possible I/M flags.
