Drive in stop-and-go traffic with at least 4 idle periods (30 seconds each) while observing the status of the OBD-II monitor on the scan tool. If the Exhaust Gas Recirculation (EGR), Heated Oxygen Sensor (HO2S), Evaporative (EVAP) emission, secondary Air (AIR) (if applicable) or catalyst efficiency monitor have not completed, drive on the highway at a constant speed over 40 mph not to exceed 65 mph for up to 15 minutes. Heavy accelerations, sudden decelerations and wide open throttles are not recommended. If the scan tool sends out a three pulse beep at any time, the OBD-II drive cycle has completed.

If the EGR, HO2S, EVAP, secondary AIR (if applicable) or catalyst efficiency monitor has not completed, perform the corresponding monitor verification drive cycle. See MONITOR REPAIR VERIFICATION DRIVE CYCLES.
Bring the vehicle to a stop and retrieve Continuous Memory DTCs to verify the DTC P1000 has been erased.
