for compliance to a state emissions program.
Some latest vehicle models may support two types of I/M
Readiness tests:
A. Since DTCs Cleared -indicates status of the 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 emissions
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.
1) Use UP/DOWN button to select I/M Readiness from
Diagnostic Menu and press OK button.
2) If the vehicle supports both types of tests, then both types
shows on the screen for selection.
