Failure Records Data

In addition to Freeze Frame data the PCM may also store Failure Records data when a DTC reports a failure. Unlike Freeze Frame data, Failure Records data can be stored by DTCs that DO NOT illuminate the MIL.

The Freeze Frame/Failure Records data may be retrieved through the Diagnostic Trouble Code menu on scan tool. If more than one DTC is set, review the odometer or engine run time data located in the Freeze Frame and Failure Records info to determine the most current failure.

Keep in mind that once Freeze Frame or Failure Record is selected, the parameter and input data displayed will look just like the normal PCM data except the parameters will not vary since stored data is being displayed.

IMPORTANT: Always capture the Freeze Frame/Failure Records information with the scan tool BEFORE proceeding with diagnosis. Clearing DTCs, disconnecting the battery, disconnecting the PCM or body connectors, or procedures performed during diagnosis may erase or overwrite the stored Freeze Frame/Failure Records data. Loss of this data may prevent accurate diagnosis of an intermittent or difficult to set DTC.
