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.
Mis
¿
re
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 mis
¿
re,
and monitoring fuel demands.
Non-Continuous Monitors
-- Unlike the continuous monitors, many emissions
and engine system components require the vehicle to be operated under
speci
¿
c
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
I/M refers to Inspection and Maintenance that is legislated by the Government
to meet federal clean-air standards. I/M Readiness indicates whether or not the
various emissions-related systems on the vehicle are operating properly and are
ready for Inspection and Maintenance testing.
The purpose of the I/M Readiness Monitor Status is to indicate which of the
vehicle’s Monitors have run and completed their diagnosis and testing, and
which ones have not yet run and completed testing and diagnosis of their
designated sections of the vehicle’s emissions system.
The I/M Readiness Monitor Status function also can be used (after repair of
a fault has been performed) to confirm that the repair has been performed
correctly, and/or to check for Monitor Run Status.
This function can also be done by tapping [I/M Readiness] directly on the Job
Menu.
