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 whether your vehicle's
emissions components are working properly. The codes may not be read if you
go through the testing just after the 12-volt battery has gone dead or been
disconnected.
To check if they are set, set the power mode or 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 tested before the readiness codes are
set, 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 power system 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. Turn the power system on.
5. 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 . 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).
6. 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.
7. Park the vehicle and leave the power system off for 6 hours.
The readiness codes are erased when the 12-volt 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.
