DTC Check / Clear [11/2018 - 08/2020]

NOTE:

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.

HINT:

DTCs which are stored in the ECM can be displayed on the Techstream. The Techstream 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.

Turn the ignition switch to ON.
Turn the Techstream on.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Powertrain > Engine > Trouble Codes

Check the DTC(s) and Freeze Frame Data, and then write them down.
