Failure Records Data

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.

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.
