Tech Tips

GTS only:

Compared to normal mode, check mode is more sensitive to malfunctions. Therefore, check mode can detect malfunctions that may not be detected in normal mode.

Note

The freeze frame data and all the stored DTCs other than permanent DTCs are cleared if: 1) the ECM is changed from normal mode to check mode or vice versa; or 2) the ignition switch is turned from ON to ACC or off while in check mode. Before changing modes, always check and make a note of the freeze frame data and any DTCs other than permanent DTCs.
