Retrieving I/M Readiness Status
The I/M Readiness function is used to check the operations of
the Emission System on OBD II compliant vehicles. It is an
excellent function to use prior to having a vehicle inspected for
compliance with a state emissions program.
CAUTION - By clearing trouble codes you also clear the readiness
status for the individual emission system readiness test. In order to
reset the monitors, the vehicle must be driven through a complete
drive cycle with no trouble codes in memory. The number of reset
times varies depending on the vehicle models.
Some latest vehicle models may support two types of
I/M
Readiness
tests:
A.
Since DTCs Cleared
-
indicates the status of monitors since
DTCs are erased.
B.
This Drive Cycle
-
indicates the status of monitors since the
beginning of the current drive cycle.
