Freeze frame data
- The freeze frame data consists of data for vehicle and transaxle control system operation conditions when malfunctions in the transaxle control system are detected and stored in the TCM.
- Freeze frame data is stored at the instant the malfunction indicator lamp illuminates, and only a part of the DTC data is stored.

Snapshot data
- The data for all DTCs currently detected is stored.

Recorded DTC timing
- For DTCs with one drive cycle, data is recorded during the malfunction determination period.
- For DTCs with two drive cycles, data is recorded during non-determination (1st diagnosis) periods.

3. Then, select the "Retrieve CMDTCs" and perform procedures according to directions on the IDS screen.

4. Verify the DTC according to the directions on the screen.
