or "Complete", it will remain in this state. A number of factors,
including erasing of diagnostic trouble codes (DTCs) with a code reader
or a disconnected battery, can result in Readiness Monitors being set
to "Not Ready". Since the three continuous monitors are constantly
evaluating, they will be reported as "Ready" all of the time. If testing
of a particular supported non-continuous monitor has not been
completed, the monitor status will be reported as "Not Complete" or
"Not Ready."
In order for the EOBD monitor system to become ready, the vehicle
should be driven under a variety of normal operating conditions.
These operating conditions may include a mix of highway driving and
stop and go, city type driving, and at least one overnight-off period.
For specific information on getting your vehicle‟s EOBD monitor
system ready, please consult your vehicle owner‟s manual.
