NOTE: When negative battery cable is disconnected, all readiness test codes are cleared. If engine is stalls or is stopped while performing steps 2- 5, repeat procedure from beginning.

Ensure fuel level is between 60 and 90 percent of fuel tank capacity (not full). Turn ignition off and allow vehicle to sit for more than 8 hours. At start of procedure, ensure ambient temperature is 20-95°F (-7-35°C). Connect scan tool to DLC.
Start engine and drive vehicle for about 15 minutes. During drive, keep vehicle speed steady between 50-70 MPH, without moving accelerator pedal, for about 1 minute. Bring vehicle to a stop. Allow engine to run at idle speed.
Repeat step 2, two more times, for a total of 3 times. Readiness code should now be set. Use scan tool to check readiness code. If readiness code is not set, go to next step.
If ambient temperature is less than 32°F (0°C), hold engine speed at 3000 RPM under no load condition with transaxle in Park or Neutral until radiator cooling fan comes on.
Remove and install gas cap.
Drive vehicle for about 20 minutes on highway/freeway. During drive, keep vehicle speed steady between 50-70 MPH, without moving accelerator pedal, for about 1 minute. Bring vehicle to a stop. Allow engine to run at idle speed.
Repeat step 6, two more times, for a total of 3 times. Readiness code should now be set. Use scan tool to check readiness code.
