Toyota Sienna Service Manual: 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 off or turned to the ACC position from the ON position while in check mode.

    Before changing modes, always check and make a note of any DTCs and freeze frame data.
