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 of the stored DTCs and Freeze Frame Data are cleared if: 1) the ECM is changed from normal mode to check
Removal
REMOVAL CAUTION / NOTICE / HINT The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during camshaft removal/installation are shown below.
