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.

Display item list

Item No.	Item name	Data item	Unit
1	Odometer	Total driving distance after the diagnosis code is generated	km
2	Ignition cycle	Number of times the ignition switch is turned "OFF (LOCK or ACC)" after the past failure transition	Number of counts.
4	Accumulative minute	Accumulative time for current malfunction of diagnosis code	min
