Check Mode Procedure
CHECK MODE PROCEDURE HINT: Compared to normal mode, check mode is more sensitive to malfunctions. Therefore, check mode can detect malfunctions that cannot be detected in normal mode.
NOTICE: All the stored DTCs and freeze frame data are cleared if: 1) the ECM is changed from normal mode to check
