SupraIV electrical issues

Hi, I've got a 2019 Toyota SupraIV with a gasoline engine and I'm experiencing some weird electrical issues at only 29635 km. I'm getting sporadic errors in driving mode, error lamps light up randomly, and the audio/nav system sometimes fails. Sometimes a control unit shuts down or becomes unresponsive. An error is also stored in the error memory. Any ideas?

A 2019 Toyota SupraIV is experiencing sporadic electrical issues, including random error lamps, unresponsive control units, and failures in the audio/navigation system. The problem is identified as a BUS system issue, potentially caused by a defective cable connection to the control unit. The suggested solution is to inspect the cable connection and, if unresolved, seek professional repair at a workshop.

Hey, I had something similar happen with my SupraIV a while back. Were you able to pull any specific error codes? It sounds like it could be a BUS system problem. Is the check engine light on?

Yeah, I was able to get the error codes read at a friend's garage. The error log mentions a BUS system problem. You are right! Where exactly was the BUS system problem?

For me, it ended up being a defective cable connection to the control unit, which connected to the BUS system. If it is this, go to the next workshop. My workshop charged me 155€ for this repair.

Thanks for the info! I'll check the cable connection to the control unit, and if that doesn't resolve it, I'll take it to a workshop. Very helpful!
