CHECK OF FREEZE FRAME DATA

To detect fault and store the diagnosis code, the ETACS-ECU obtains data before the confirmation of the diagnosis code and data when the diagnosis code is confirmed, and then stores the current condition of the ETACS-ECU. By analysing each data from M.U.T.-III, the troubleshooting can be performed more efficiently. Display items of the freeze frame data are as follows.

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 "ON" or "LOCK (OFF)" after the past failure transition.	Number of counts is displayed.
3	Elapsed time	Total elapsed time after a diagnosis code is generated	min^*
4	Accumulated minute	Cumulative time for current malfunction of diagnosis code	min

note

^*: Total elapsed time can be stored up to 65534 minutes. The display of M.U.T.-III is fixed to 65534 minutes after 65534 minutes have elapsed. Or, if the battery is disconnected, the total elapsed time cannot be measured properly. Thus, 65535 minutes (null value) is displayed. Since the value is calculated according to the information from the ETACS-ECU, a proper value may not be displayed when the ETACS-ECU time-out has occurred.
