CHECK ON FREEZE FRAME DATA
When judging malfunctions and storing diagnostic trouble codes, the On board charger/DC-DC converter should store the malfunction status per diagnostic trouble code. This function is called "Freeze frame data". By analyzing this "Freeze frame data" with the scan tool (M.U.T.-IIISE), an effective troubleshooting can be performed. The display items of freeze frame data are shown 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 4 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 diagnostic trouble code (DTC) is not set before driving the OBD-II drive cycle. Erase the DTC if it has been set.
