Freeze frame data, Snapshot data

• The freeze frame data and snapshot data consist of vehicle condition data when a malfunction is detected.
• The freeze frame data and snapshot data are displayed automatically when displaying CMDTC.

Freeze frame data 

• For the freeze frame data, only a part of the DTC data is stored.
• If there are several malfunctions in the engine control system, the data for the malfunction which occurred initially is stored. After that, if a misfire or malfunction in the fuel injection control occurs, the misfire or malfunction data in the fuel injection control overwrites the previously stored data. However, if the previously stored freeze frame data is due to a misfire or malfunction in the fuel injection control, the data is not overwritten.

Snapshot data 

• For the snapshot data, the data for all DTCs currently detected is stored.
• For DTCs with one drive cycle, the data is stored when a malfunction is determined.
• For DTCs with two drive cycles, the data is stored when a malfunction is not determined (first diagnosis) and a malfunction is determined (second diagnosis).
