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
31, then interpret the LED indications as follows:
Interpreting I/M Readiness Test Results
1. GREEN LED - Indicates that all engine
systems
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 LED - Determine from the
CODE RETRIEVAL
(page 31) 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 / countries) 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.
If the illumination of the Yellow LED is
being caused by monitors that "have
not run" their diagnostic testing, then
the issue of the vehicle being ready
for an Emissions Test (Smog Check)
depends on the emissions regulations
and laws of your local area.
- Some areas require that all
Monitors indicate a "Has Run"
status before they allow an
Emissions Test (Smog Check) to
be performed. Other areas only
require that some, but not all, Monitors have run their self-
diagnostic testing before an Emissions Test (Smog Check)
may be performed.
From the code retrieval procedure, determine the status of
each Monitor (a solid Monitor icon shows Monitor "Has Run"
status, a flashing Monitor icon indicates "Has Not Run" status).
Take this information to an emissions professional to
determine (based on your test results) if your vehicle is ready
for an Emissions Test (Smog Check).
