CHR Sporadic Error Lamps

My 2022 Toyota CHR Hybrid, with 108059 km, is throwing sporadic errors in driving mode and lighting up random error lamps. Audio and navigation are cutting out sometimes, and the control units seem to freeze up temporarily. Scan tool shows stored errors. Anyone seen this?

Sounds familiar. I've got a CHR, though unsure of the year, and had similar weirdness. Check engine light was on and off, radio would die, that kind of thing. Did you use a scan tool to check for error codes yourself?

Yeah, I scanned it. Got a bunch of codes related to the BUS system, but nothing specific. Was yours the same, a bunch of vague communication errors?

Exactly! Turns out it was a faulty cable connection to one of the control units. Apparently, it messes with the whole BUS. Eventually I had to take it to a workshop because I do not have the right tools to troubleshoot the harness. I hope it's the same for you

Thanks for the insight! Took it in, and you were spot on. Bad cable connection to the control unit. Repair was 155€. Appreciate the help!
