Toyota RAV4 (XA40) 2013-2018 Service Manual: Dtc check / clear

Notice:

When the diagnosis system is changed from normal mode to check mode or vice versa, all dtcs and freeze frame data recorded in normal mode are erased. Before changing modes, always check and make a note of any dtcs and freeze frame data.
