When the diagnosis system is changed from normal mode to check mode or vice versa, all DTCs and Freeze Frame Data recorded in normal mode are cleared. Before changing modes, always check and make a note of DTCs and Freeze Frame Data.
DTCs which are stored in the ECM can be displayed on the GTS. The GTS can display the confirmed and pending DTCs.
Some DTCs are not stored if the ECM does not detect the same malfunction again during a second consecutive driving cycle. However, such malfunctions, detected on only one occasion, are stored as pending DTCs.
CHECK DTC

Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Check the DTC(s) and Freeze Frame Data, and then write them down.
