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 drive cycle that enables a monitor and
sets readiness codes to “Ready” varies for each individual monitor. Once a monitor is set
as “Ready” 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 OBD 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 OBD monitor system ready, please
consult your vehicle owner’s manual.
2.6 OBD II Definitions
Powertrain Control Module (PCM)
-- OBD II terminology for the on-board computer that
controls engine and drive train.
Malfunction Indicator Light (MIL)
-- Malfunction Indicator Light (Service Engine Soon,
Check Engine) is a term used for the light on the instrument panel. It is to alert the driver
and/or the repair technician that there is a problem with one or more of vehicle's systems
and may cause emissions to exceed federal standards. If the MIL illuminates with a
steady light, it indicates that a problem has been detected and the vehicle should be
serviced as soon as possible. Under certain conditions, the dashboard light will blink or
flash. This indicates a severe problem and flashing is intended to discourage vehicle
operation. The vehicle onboard diagnostic system cannot turn the MIL off until the
necessary repairs are completed or the condition no longer exists.
