Toyota Corolla Cross: 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 engine stop and start ECU is switched from normal mode to check mode or vice versa; or 2) the ignition switch is turned from ON to ACC or off while in check mode. Before changing modes, always check for and note any DTCs and freeze frame data.
CHECK MODE PROCEDURE
(a) Check and ensure the following conditions:
(1) Auxiliary battery voltage is 11 V or higher.
(2) Shift lever is in P or N.
(3) A/C switch is off.
