Check Mode Procedure

2009 Toyota Camry HybridSECTION Check Mode Procedure

HINT:

Techstream only

Compared to the normal mode, check mode is more sensitive to malfunctions. Therefore, check mode can detect the malfunctions that cannot be detected in normal mode.

NOTE: 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 power switch is turned from on (READY) 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.

      1. Battery positive voltage 11 V or more.
