2.2 Retrieving I/M Readiness Status
I/M Readiness function is used to check the operations of the Emission System on OBD2 compliant vehicles. It is an
excellent function to use prior to having a vehicle inspected for compliance to a state emissions program.
Some latest vehicle models may support two types of I/M Readiness tests:
DTCs Cleared - indicates status of the monitors since the DTCs are erased.
This Drive Cycle — indicates status of monitors since the beginning of the current drive cycle.
An I/M Readiness Status result of “NO” does not necessarily indicate that the vehicle being tested will fail the state I/M
inspection. For some states, one or more such monitors may be allowed to be “Not Ready” to pass the emissions
inspection.
