Testing of
Readiness Codes
Your vehicle has readiness codes as part of the onboard self-diagnostic system.
Some states use these codes for testing to verify your vehicle’s emissions
components are working properly. The codes may not be read if you go through the
testing just after the battery has gone dead or been disconnected.
To check if they are set, set the power mode to ON without starting the engine.
The malfunction indicator lamp will come on for several seconds. If it goes off, the
readiness codes are set. If it blinks five times, the readiness codes are not set.
If you are required to have your vehicle emissions tested before the readiness codes
are set, prepare the vehicle for retesting by doing the following:
1.
Fill the gas tank to appr

oximately 3/4 full.
2.
Park the

vehicle and leave the engine off for 6 hours or more.
3.
Make sure

the ambient temperature is between 40°F and 95°F (4°C and 35°C).
4.
Start the engine without

touching the accelerator pedal, and let it idle for 20
seconds.
5.
Keep the

vehicle in Park (P). Increase the engine speed to 2,000 rpm, and hold it
there for about 3 minutes.
6.
Let the engine idle with

your foot off the accelerator for 20 seconds.
7.
Select a nearby, lightl

y traveled major highway where you can maintain a speed
of 50 to 60 mph (80 to 97 km/h) for at least 20 minutes. Drive on the highway
with the vehicle in Drive. Do not use cruise control. When traffic allows, drive
for 90 seconds without using the accelerator pedal. (Vehicle speed may vary
slightly; this is OK.) If you cannot do this for a continuous 90 seconds because of
traffic conditions, drive for at least 30 seconds, then repeat two more times (for
a total of 90 seconds).
8.
Drive in city or suburban

traffic for at least 10 minutes. When traffic conditions
allow, let the vehicle coast for several seconds without using the accelerator
pedal or the brake pedal.
9.
Park the

vehicle and leave the engine off for 30 minutes.
The readiness codes are erased when the battery is disconnected, and set again
only after several days of driving under a variety of conditions.
If an emissions testing facility determines that the readiness codes are not set, you
may be requested to return at a later date to complete the test, or see your dealer.
