Кто утопил CAN-шину? Мазда 3, которая всех запутала

2020 Mazda 3. She came in with a complaint: sometimes it wouldn't start, sometimes it would. Also, a string of error codes would periodically flash across various modules. The symptoms were intermittent: they were there today, gone tomorrow. The client was tired of guessing. I started by checking the ground, power, and CAN bus... What ultimately ruined the entire bus and where the water was coming from—watch the video. It turned out to be completely different from where I was initially looking. #mazda #mazda3 #mazda3 #autoelectrics #diagnostics #canbus #canbus #carrepair
