OBD-II Drive Cycle Procedure

NOTE: Once drive cycle is started, engine must not be turned off.
  1. Start engine and drive vehicle. Drive vehicle in stop and go traffic for at least 20 minutes with at least 4 idle periods. Drive vehicle on an expressway for 10-15 minutes. Access and monitor IAT PID during expressway drive. Heavy accelerations, sudden accelerations or wide open throttle applications are not recommended.
  2. If IAT PID is less than 40°F (4°C) at any time during expressway drive, the Evaporative Emission Monitor will not complete. Access On-Board System Readiness menu to check completion status. Rerun Continuous Memory Self-Test to check DTC P1000 status. If Evaporative Emission Monitor is the only monitor not showing completion and DTC P1000 has been cleared, OBD-II drive cycle has been completed.
