STOP AND START SYSTEM CHECK MODE PROCEDURE

Tip:

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

Note:

All the stored DTCs and freeze frame data are cleared if: 1) the engine stop and start ECU is switched 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 for and note any DTCs and freeze frame data.
