Emissions Testing
Testing of Readiness Codes
Your vehicle has readiness code as part of the onboard self diagnostic system.
Some states use these codes for testing to verify whether your vehicle’s emissions
components are working properly.
The codes may not be read properly if testing is performed 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 then 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 tested before the readiness codes are ready,
prepare the vehicle for retesting by doing the following:
1. Fill the gas tank to approximately 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
(P (continuously variable transmission) or (N (manual
transmission). 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, lightly 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 in
(D (continuously variable transmission) or 5th (manual transmission). Do not use
cruise control. When traffic allows, drive for 90 seconds without moving the
accelerator pedal. (Vehicle speed may vary slightly; this is okay.) If you cannot do
this for a continuous 90 seconds because of traffic conditions, drive for at least 30
seconds, then repeat it two more times (for a total of 90 seconds).
1Testing of Readiness Codes
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 a testing facility determines that the readiness
codes are not set, you may be requested to return at
a later date to complete the test.
If the testing facility determines the readiness codes
are still not set, see a dealer.
