Computer Issues

I have a Lexus ES300 2003. Every time the car is turned off the computer resets. The fuses are all ok. Does anyone have any ideas on how to fix this issue.

The ecu has a memory circuit, which I think is ECU-B, or ECU-A, you'd have to check that pin has power when the car is turned off. I bet this is wiring issue/fuse issue/relay issue, before anything else.

You might want to replace the open circuit relay
