Check Of Freeze Frame Data
The freeze frame data can be checked by using the scan tool (M.U.T.-IIISE).
When detecting fault and setting the DTC, the ECU connected to CAN bus line obtains the data before the determination of the DTC and the data when the DTC is determined, 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.
