CHECK ON FREEZE FRAME DATA
The freeze frame data can be checked by using scan tool (M.U.T.-IIISE).
 
 
When detecting the trouble and storing the diagnostic trouble code, the ECU connected to CAN bus line obtains the data when the diagnostic trouble code is confirmed, and then stores the ECU status of that time. By analyzing each data from scan tool (M.U.T.-IIISE), the troubleshooting can be performed more efficiently. The displayed items are as the table below.

OBD- II DRIVE CYCLE
All kinds of diagnostic trouble codes (DTCs) can be monitored by carrying out a short drive according to the following 7 drive cycle patterns. In other words, doing such a drive regenerates any kind of trouble which involves illuminating the Malfunction Indicator lamp (SERVICE ENGINE SOON or Check Engine lamp) and verifies the repair procedure has been eliminated [the trouble the Malfunction Indicator lamp (SERVICE ENGINE SOON or Check Engine lamp) is no longer illuminated].
cautionTwo technicians should always be in the vehicle when carrying out a test.
noteCheck that the diagnosis trouble code (DTC) is not set before driving the OBD-II drive cycle. Erase the DTC if it has been set.
