I have an o2 corolla s. Everytime i shut the key off it resets the ecu, so my readiness monitors clear out and the car has to relearn itself every time i start it. I have checked all the fuses and none are blown. Is there a way to check the ecu to see if its bad or has anyone had a similar problem?
Incorrect. B+ is ignition power to sensors, ignition coils, etc. BATT is the one that's always hot to preserve memory. It's the red/white wire in the top-right corner of either the leftmost or rightmost ECU connector. I forget which.
