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,
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
24, then interpret the LED indications as follows:
Interpreting I/M Readiness Test Results
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.
2. YELLOW
PROCEDURE (page 24) which of the two possible conditions is
causing the yellow LED to light.
If a "PENDING" Diagnostic Trouble
Code is causing the yellow LED to
light, it is possible that the vehicle
will be allowed to be tested for
emissions and certified. Currently,
most areas (states) will allow an
Emissions Test (Smog Check) to be
performed if the only code in the
vehicle's computer is a "PENDING"
Diagnostic Trouble Code.
