Some latest vehicle models may support two types of
I/M
Readiness
tests:
A.
Since DTCs Cleared
-
indicates status of monitors since the
DTCs are erased.
B.
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 emission inspection.
“OK”
-- Indicates that a particular monitor being checked has
completed its diagnostic testing.
“INC”
-- Indicates that a particular monitor being checked has
not completed its diagnostic testing.
“N/A”
-- The monitor is not supported on that vehicle.
There are two ways to retrieve I/M readiness status.
A.
Retrieve I/M Readiness Status with One-Click I/M
Readiness Key
By simply pressing the
One-Click I/M Readiness Key
,
you can
retrieve the I/M readiness status. The screen will show as below.

will illuminate and different audio tones will be heard.
