4.6 Retrieving I/M Readiness Status
I/M Readiness function is used to check individual Emission System
readiness tests on OBDII compliant vehicles. It is an excellent function to use
prior to having a vehicle inspected for compliance to a state emissions
program. CAUTION - by clearing trouble codes you also clear the readiness
status for the individual emission system readiness tests. In order to reset
these monitors, the vehicle must be driven through a complete drive cycle
with no trouble codes in memory. Times for reset vary depending on vehicle.
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 “INC” 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 the testing of a particular monitor being tested is
incomplete. Additional driving is needed.
-“N/A” -- The monitor is not supported on that vehicle.
