status. This information is very important since different areas of the
state/country have different emissions laws and regulations concerning
Monitor Run/Not Run status.
Before an Emissions Test (Smog Check) can be performed, your
vehicle must meet certain rules, requirements and procedures
legislated by the Federal and state (country) governments where you
live.
1. In most areas, one of the requirements that must be met before a
vehicle is allowed to be Emissions Tested (Smog Checked) is that
the vehicle does not have any Diagnostic Trouble Codes present
(with the exception of PENDING Diagnostic Trouble Codes).
2. In addition to the requirement that no Diagnostic Trouble Codes be
present, some areas also require that all the Monitors that a
particular vehicle supports indicate a "Has Run" status condition
before an Emissions Check may be performed.
3. Other areas may only require that some (but not all) Monitors
indicate a "Has Run" status before an Emissions Test (Smog
Check) may be performed.
Monitors with a "Has Run" status indicate that all the
required conditions they needed to perform diagnosis
and testing of their assigned engine area (system) have
been met, and all diagnostic testing has completed
successfully.
Monitors with a "Has Not Run" status have not yet met
the conditions they need to perform diagnosis and
testing of their assigned engine area (system), and have
not been able to perform diagnostic testing on that
system.
The green, yellow and red LEDs provide a quick way to help you
determine if a vehicle is ready for an Emissions Test (Smog Check).
Follow the instructions below to perform the Quick Check.
Perform the Code Retrieval Procedure as described on page 17, then
interpret the LED indications as follows:

1. GREEN LED - Indicates that all engine
systems are "OK" and operating
normally (all Monitors supported by the
vehicle have run and performed their
self-diagnostic testing). The vehicle is
ready for an Emissions Test (Smog
Check), and there is a good possibility
that it can be certified.
