OBD-II Drive Cycle: Description

The purpose of the OBD-II drive cycle is to execute the OBD-II monitors and identify any concerns with the OBD-II system. The DTC P1000 code will be erased of all OBD-II monitors have completed during the OBD-II drive cycle. The scan tool will be used to observe the status of each OBD-II monitor at the completion of the OBD-II drive cycle. The completion status of the Exhaust Gas Recirculation (EGR), Heated Oxygen Sensor (HO2S), Evaporative Emission (EVAP), Secondary Air Injection (AIR) (if applicable) and catalyst efficiency monitors can be monitored during the OBD-II drive cycle by viewing the ON-BOARD READINESS menu on the scan tool. For the procedure of each OBD-II drive cycle, see MONITOR REPAIR VERIFICATION DRIVE CYCLES  under DRIVE CYCLES.
