CHECK OF FREEZE FRAME DATA


The freeze frame data can be checked by using M.U.T.-III (Refer to GROUP 00 - How to Use Troubleshooting and Inspection Service Points - Diagnosis Function ).

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.
