Freeze Frame Priority

The freeze frame indicates only the operating conditions under which the maturing code was set. While these conditions are usually the same as those that trigger the maturation of the diagnostic trouble code (DTC), there can be exceptions. This first condition is important for fuel system and misfire DTCs, as it is the condition the vehicle must repeat successfully during a test to allow the Task Manager to erase a DTC and turn off the Malfunction Indicator Lamp (MIL) on its own.

Should the Task Manager determine that the DTC can be erased, the freeze frame related to that code is also eliminated.
