Sfi System -- Check Mode Procedure


HINT:
Intelligent tester only:
Compared to normal mode, check mode is more sensitive to malfunctions. Therefore, check mode can detect the malfunctions that cannot be detected by normal mode.
NOTICE:
All the stored DTCs and freeze frame data are erased if: 1) the ECM is changed from normal mode to check mode or vice versa; or 2) the ignition switch is turned from on (IG) to on (ACC) or off while in check mode. Before changing modes, always check and make a note of any DTCs and freeze frame data.
