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.

 If a “Stored” 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.

 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.

 If the illumination of the Yellow LED is being caused by

monitors that have not completed their diagnostic testing,

then the issue of the vehicle being ready for an Emissions

Test depends on the emissions regulations and laws of your

local area.

NOTE: From the code retrieval procedure, determine the status of

each Monitor. Take this information to an emissions professional to

determine (based on your test results) if your vehicle is ready for an

Emissions Test.

3) RED LED – Indicates there is a problem with one or more of

the vehicle‟s system. A vehicle displaying a red LED is

definitely not ready for an Emissions Test. The red LED is also

an indication that there are DTCs present. The MIL lamp on the

vehicle‟s instrument panel will light steady. The problem that is

causing the red LED to light must be repaired before an
