emissions control strategy.
Continuous Monitors -- Some of the vehicle components or systems
are continuously tested by the vehicle's OBD II system, while others are
tested only under specific vehicle operating conditions. The continuously
monitored components listed below are always ready:
1）Misfire
2）Fuel System
3）Comprehensive Components (CCM)
Once the vehicle is running, the OBD II system is continuously checking
the above components, monitoring key engine sensors, watching for
engine misfire, and monitoring fuel demands.
Non-Continuous Monitors -- Unlike the continuous monitors, many
emissions and engine system components require the vehicle to be
operated under specific conditions before the monitor is ready. These
monitors are termed non-continuous monitors and are listed below:
1) EGR System
2) O2 Sensors
3) Catalyst
4) Evaporative System
5) O2 Sensor Heater
6) Secondary air Injection
7) Heated Catalyst
8) A/C system

2.5 OBD II Monitor Readiness Status

OBD II systems must indicate whether or not the vehicle's PCM's monitor
system has completed testing on each component. Components that
have been tested will be reported as "Ready", or "Complete", meaning
they have been tested by the OBD II system. The purpose of recording
readiness status is to allow inspectors to determine if the vehicle's OBD II
system has tested all the components and/or systems.
The powertrain control module (PCM) sets a monitor to "Ready" or
"Complete" after an appropriate drive cycle has been performed. The
