CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using the 
M.U.T.-III.
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 from M.U.T.-III, the troubleshooting can be 
performed more efficiently. The displayed items are 
as the table below.
