Retrieve I/M Readiness Status
IMPORTANT: 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.
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.
YES – all monitors supported on the vehicle have completed their
diagnostic testing and the MIL light is not on
NO – at least one monitor supported on the vehicle has not
completed its diagnostic testing, and (or) the “Check Engine”(MIL) light
is on
READY – indicates that a particular monitor being checked has
completed its diagnostic testing
