OBDII Drive Cycle-- A specific mode of vehicle operation that provides conditions
required to set all the readiness monitors applicable to the vehicle to the “Ready”
condition. The purpose of completing an OBD II drive cycle is to force the vehicle to run
its onboard diagnostics. Some form of a drive cycle needs to be performed after DTCs
have been erased from the PCM's memory or after the battery has been disconnected.
Running through a vehicle's complete drive cycle will “set” the readiness monitors so
that future faults can be detected. Drive cycles vary depending on the vehicle and the
monitor that needs to be reset. For vehicle specific drive cycle, consult the vehicle's
Owner's Manual.
