4.6 LED Interpretation
1) GREEN LED -- Indicates that engine systems are “OK” and operating normally
(the number of Monitors supported by the vehicle which have run and performed their
self-diagnostic testing is in the allowed limit. MIL is off). There are no stored and
pending DTCs. The vehicle is ready for an Emissions Test, and there is a good
possibility that it can be certified.
2) YELLOW LED -- With MIL off, there may be three possible conditions to cause
the yellow LED to light.
A. If a”Stored” Diagnostic Trouble Code is causing the Yellow LED to light, it is
ttill possible that the vehicle will be allowed to be test
ed for emissions and certified.
B. If a “Pending” Diagnostic Trouble Code is causing the Yellow LED to light, it
is still possible that the vehicle will be allowed to be tested for emissions and
certified.
