Hey guys, so this 2021 hyundai elantra has multiple warning lights and no communication from different module. In this video we gonna be using oscilloscope and check our communication data if we can see something that will help us figure out this problem. At the end of the video, i was ready to call and replace the smart junction box but my service advisor called me and told me that theres a new update for the smart junction box. So far after the update we never see the car came back or unless it went to a different dealer. Thanks again for watching this channel and let me know your suggestions.
