I/M READINESS TESTING
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
36, 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 LED - Determine from the
CODE RETRIEVAL PROCEDURE (page
36) 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.
