OBD-II Drive Cycle Description (Gasoline)
NOTE:
Rough road conditions may prevent certain steady state conditions and steady accelerations from validating the transmission and load related monitors. On models with Power Take-Off (PTO), disengage PTO system before performing Drive Cycle.
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.
