FREEZE FRAME DATA CHECK


By using M.U.T.-III, the freeze frame data can be checked.

When detecting fault and storing the diagnosis code, the ECU connected to CAN bus line obtains the data before the determination of the diagnosis code and the data when the diagnosis code is determined, and then stores the ECU status of that time. By analysing each data using M.U.T.-III, troubleshooting can be carried out efficiently. The displayed items are as the table below.
