OBD-II Drive Cycle Description

WARNING: This page does not describe the selected car, but rather 26 other vehicles, including the 1999 Mercury Tracer, 1999 Mercury Sable, 1999 Mercury Mystique, 1999 Mercury Mountaineer, and 1999 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.

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.

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.
