CHECK MODE PROCEDURE
HINT:
Compared to normal mode, check mode is more sensitive to
malfunctions. Therefore, check mode can detect the malfunc -
tions that cannot be detected by normal mode.
In check mode, the ECM sets DTCs using 1 trip detection logic.
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; 2) the ignition switch is turned from ON to ACC
or OFF while in check mode. Before changing modes, al -
ways check and make a note of any DTCs and freeze frame
data.
