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.
  1. 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.
