Check Of Freeze Frame Data
The freeze frame data can be checked by using scan tool (M.U.T.-IIISE).
When detecting the trouble and storing the DTC, the ECU connected to CAN bus line obtains the data when the DTC is confirmed, and then stores the ECU status of that time. By analyzing each data from scan tool (M.U.T.-IIISE), the troubleshooting can be performed more efficiently. The displayed items are as the table below.
