OBD-II drive cycle is a pattern of driving in which the PCM will execute all OBD-II diagnostic monitors. Drive cycle can be used to cause a DTC to set if a fault is present or to verify that a DTC will not return after a repair has been completed. If drive cycle is complete and P1000 is not cleared, repeat entire drive cycle.
