Obtain Freeze Frame Data

Freeze frame data can be helpful in duplicating and diagnosing adaptive fuel concerns. This data (a snapshot of certain parameter identification [PID] values, recorded at the time the DTC was stored in continuous memory) is helpful to determine how the vehicle was being driven when the fault occurred, and can be especially useful on intermittent concerns. Freeze frame data, in many cases, can help to isolate possible areas of concern as well as rule out others. Refer to FREEZE FRAME DATA  for a more detailed description of this data.
