I/M READINESS TESTING<br />

Perform the CODE RETRIEVAL PROCEDURE as described on page<br />

33, then interpret the LED indications as follows:<br />

Interpreting I/M Readiness Test Results<br />

1. GREEN LED - Indicates that all engine<br />

systems are "OK" and operating<br />

normally (all Monitors supported by the<br />

vehicle have run and performed their<br />

self-diagnostic testing). The vehicle is<br />

ready for an Emissions Test (Smog<br />

Check), and there is a good possibility<br />

that it can be certified.<br />

2. YELLOW LED - Determine from the CODE RETRIEVAL<br />

PROCEDURE (page 33) which of the two possible conditions is<br />

causing the yellow LED to light.<br />

� If a "PENDING" Diagnostic Trouble<br />

Code is causing the yellow LED to<br />

light, it is possible that the vehicle<br />

will be allowed to be tested for<br />

emissions and certified. Currently,<br />

most areas (states / countries) will<br />

allow an Emissions Test (Smog<br />

Check) to be performed if the only<br />

code in the vehicle's computer is a<br />

"PENDING"<br />

Code.<br />

Diagnostic Trouble<br />

� If the illumination of the Yellow LED<br />

is being caused by monitors that<br />

“have not run” their diagnostic<br />

testing, then the issue of the vehicle<br />

being ready for an Emissions Test<br />

(Smog Check) depends on the<br />

emissions regulations and laws of<br />

your local area.<br />

- Some areas require that all Monitors indicate a "Has Run"<br />

status before they allow an Emissions Test (Smog Check) to<br />

be performed. Other areas only require that some, but not all,<br />

Monitors have run their self-diagnostic testing before an<br />

Emissions Test (Smog Check) may be performed.<br />

- From the code retrieval procedure, determine the status of<br />

each Monitor (a solid Monitor icon shows Monitor "Has Run"<br />

status, a flashing Monitor icon indicates "Has Not Run" status).<br />

Take this information to an emissions professional to<br />

determine (based on your test results) if your vehicle is ready<br />

for an Emissions Test (Smog Check).<br />
