Obd Ii Monitor Readiness Status; Obd Ii Definitions - BGS technic 63311 Manual De Instrucciones

2.4 OBD II Readiness Monitors
Continuous Monitors
Some of the vehicle components or systems are
continuously tested by the vehicle's OBDII system, while
others are tested only under specific vehicle operating
conditions.
The continuously monitored components listed below are
always ready:
Once the vehicle is running, the OBDII 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:

2.5 OBD II Monitor Readiness Status

OBD II systems must indicate whether or not the vehicle's PCM 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 scan tool 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)
OBDII 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 on-board diagnostic system can not turn the MIL off until the necessary repairs are
completed or the condition no longer exists.
