Note
When the diagnosis system is changed from the normal mode to check mode or vice versa, all DTCs and freeze frame data recorded in normal mode are erased. Before changing modes, always check and make a note of DTCs and freeze frame data.
Tech Tips
DTCs which are stored in the ECM can be displayed on the GTS. The GTS can display the current and pending DTCs.
Some DTCs are not set 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.

Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS ON.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Check the DTC(s) and freeze frame data, and then write them down.
