Hello
I believe either my S300 or my ECU has just failed. As I was troubleshooting I had the ignition on but car not running. I pulled the ECT connector off the sensor and heard an electrical buzzing, plugged the connector back in and it went away. The next time I tried to start the car, it did but barely, had a CEL, missing on a cylinder, super rich, seemed to be running on a completely different tune. So I had my computer plugged in so I hit the online button and it does not go online. nothing in my display works. I can un plug the USB and plug it in again and it recognizes it, but does not go online.
From here I tried to pull the code with the service connector and just get a solid CEL. I read on this forum that is normal though? Can we confirm this? car not running, ignition on, service connector jumped, a steady ON CEL is normal?
I also noticed a steady red light on the S300 with ignition on, don't know if that is normal but it would be nice to find a S300 LED guide. I have not tried starting the car and looking at the LED and frankly, I don't really want to start the car.
Everything looks ok in the ECU on S300, no burning or funny smells. I looked at the troubleshooting guide and a discrepancy I found was that J12 had yet to be cut, but I have been using this set up for two years without issue. I don't know what happened when I pulled that ECT connector, but I think bad things happened.
Do I need a new ECU, S300, or both? Can I transfer the hardware to a new ECU?
