READER DEFAULT CODE OBDII
LED Interpretation
The green and red LEDs provide an easy way to check if emission-related monitoring
systems complete their self-diagnostic testing.
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)
2 - RED LED – Indicates that the number of Monitors supported by the vehicle which have
run and performed their self-diagnostic testing is out of the allowed limit.
Audio Tone Interpretation
The audio tone could be configured according to the I/M Readiness Status. This function
is invaluable when working in bright areas where LED illumination alone is not sufficient.

2. Scan Tool Mode
NOTE: Only in this mode can you perform the OBDII diagnostics.
To enter this mode, please follow the steps in 4.4 Retrieving I/M Readiness Status.
The green, yellow and red LEDs provide a quick way to help you determine if a vehicle is
ready for an Emission Test.
The LED and audio tone indications are as interpreted below:
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.
