Energidriver Report post Posted January 10, 2022 Hi new here searched around and didn't find much like the problem I'm having. This randomly started this last week. While driving my controls below my touch screen all stopped working and I now have no heat. Also while this happens I get a cross traffic failure and I also notice that my passenger windows and outside temp to not work. I get a check engine light for a ton of different modules with no communication. This happens randomly sometime I drive a while before it all happens sometimes it's in start up. I had the 12v battery tested and it tested good. I also just Incase put a charge to the battery just to see if the problem went away and it didn't. I ran my car through the carwash just to make sure all sensors were clean also. Anyone ever have all there problems together? Thanks for any advice!

murphy Report post Posted January 10, 2022 Multiple failures that seem to be unrelated are usually the result of a failed ground connection. It can also be caused by a cheap OBD2 reader that corrupts the buss. Tesla had a problem at the factory where a ground stud on a frame rail was over torqued leading to it eventually snapping off. 1 toyfan2 reacted to this Quote Share this post Link to post Share on other sites
