Failure Records Data
2002 Chevrolet Express 3/4 Ton Van V8-6.5L DSL Turbo VIN FSECTION Failure Records Data
When a diagnostic test fails, the powertrain control module (PCM) stores the information as Failure Records data. Unlike Freeze Frame data, Failure Records are stored for multiple DTCs or non-emission related DTCs, that is, 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 with the scan tool. If more than one DTC is set, review the odometer or the engine run time data that is located in the Freeze Frame/Failure Records information in order to determine the most current failure. The stored information will look like normal PCM data.
