HINT: 

• Up to three of the most recent data for each "Charge Cancel History" group (user operation (connector related), charging cable/charging equipment, others, and delay) is recorded as freeze frame data.
• The latest "Charge Cancel History" freeze frame data can record data at the time a charging failure is detected as well as up to 3 seconds from that point. Freeze frame data is useful when performing troubleshooting or interviewing a customer because the plug-in charging failure condition (canceled, delayed, etc.) and user operation condition can be accurately confirmed by reading it. It can also be useful when performing a reproduction test.
• With the latest "Charge Cancel History" freeze frame data, the charging failure detection point changes between point 3 and 4 depending on the conditions.
