Ready Test Mode

repairs to the emissions-control systems of a 2001 or newer vehicle cause the vehicle's computer (Pcm) memory to be cleared.
the vehicle must go through a drive cycle to allow the Pcm to perform a series of tests to ensure that the repair was successful, and
before a emissions test can be conducted.
modern vehicles lack equipment to indicate whether the tests have been completed. With the auto code reader, you don't have to bring
the vehicle back to the workshop for retest if all required tests by the Pcm are completed.
In the ready test mode, you can easily check the I/m readiness status to determine whether an eoBd vehicle is ready for an
emission test.
to enter this mode, simply press the one-click Key at anytime. If the one-click function key is set at I/m readiness. or while the
scan tool in ready test mode, select diagnostics in the main Screen. If the scan tool is idle, it will show the result immediately. If it is
busy, it will wait till the current procedure has finished. After viewing the status, press I/M Readiness One-Click Key or ENTER button
to exit, which takes a few seconds. You will get the information screen as below.
"oK" -- Indicates that a particular monitor being checked has completed its diagnostic testing.
"Inc" -- Indicates that a particular monitor being checked has not completed its diagnostic testing.
"n/A" -- the monitor is not supported on the vehicle.
the Led and audio tone indications are as interpreted below:
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.

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.
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 can be tested for emissions.
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.
