Failure Records Data
IMPORTANT: Always capture the Freeze Frame and Failure Records information with the scan tool BEFORE proceeding with diagnosis. Loss of this data may prevent accurate diagnosis of an intermittent condition.When a diagnostic test fails, the PCM stores the information as Failure Records data. Unlike Freeze Frame data, Failure Records are stored for multiple DTCs or non-emission related DTCs (DTCs that do not illuminate the MIL). The Failure Records information is updated the first time the test fails during each ignition cycle.
Freeze Frame/Failure Records data may be retrieved through the scan tool. If more than one DTC is set review the odometer or engine run time data located in the Freeze Frame/Failure Records info to determine the most current failure. The stored information will look like normal PCM data.
