you will find the tcu tucked in the trunk ,remove the left side tail light cover then the cover just fwd of it has 2 or 3 quick release fastners you will see a silver metal box with 4 each connectors on top and one large connector at the botton of it .all you need to disconnect is only the large single white connector at the bottom of the tcu and just leave it hanging .PROBLEM SOLVED .now every time you start your car you will see a notice that says SOS MALFUNCTION on your center screen and a red or orange sign on your speedo with the same message but will go away in a fwe seconds ..GOOD LUCK..
