The ECM stores the vehicle condition when a DTC is output, and this information can be displayed using the GTS.
Freeze frame data when a DTC is output.
When a DTC is output, the freeze frame data at the time the DTC is output is stored.
When freeze frame data is stored when a DTC is output, the data is not updated or deleted until DTCs are cleared.
