2004 Outback, 2.5L, 140k miles, automatic AWD. My scanner which I've used for years on this car suddenly won't connect to the car. It flashed on and off a couple times then just went blank. Same with car running, car off, key on, etc.
I've also tested the scanner in my other car.... good to go. So it must be in the OBD connector or something near the ECU itself..... Can't remember if it's ECU (unit) or ECM (module) on the Subie.
Right now, the car seems to be running fine... just want to fix it for future diagnostics and make sure it's not a larger issue with the ECU...
