The vehicle's On-Board Diagnostic system cannot turn

the MIL off until necessary repairs are completed or

the condition no longer exists.

DTC -- Diagnostic Trouble Code that identifies which section

of the emission control system has malfunctioned.

OBD II 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 on-board 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.

Freeze Frame Data -- When an emissions related fault occurs, the

OBD II system not only sets a code but also records a snapshot of

the vehicle operating parameters to help in identifying the problem.

This set of values is referred to as Freeze Frame Data and may

include important engine parameters such as engine RPM, vehicle

speed, air flow, engine load, fuel pressure, fuel trim value, engine

coolant temperature, ignition timing advance, or closed loop status.

Parameter ID (PID) --
