How To (if possible) Reflash '06 Toyota Corolla ECM
I am hoping to replace a possibly faulty ECM from the dealer with a used
one. The parts appear to be interchangeable, but when I installed the used
one the car didn't recognize it and it wouldn't start. I asked Toyota if they
knew how to reflash or program this used ECM but they didn't even know
enough to give me a real answer.
Here are the part numbers in case it helps:
Old ECM from Toyota Dealer : 89661 - 02K - 23
Just bought Used ECM : 89661 - 02K - 20
I'm replacing *again* it as it's had the check engine light on since I bought
it, and even after the transmission and ECM had been replaced previously.
I'm aware of a TSB regarding this nonsense and I'm trying to give this car
one last shot before I look for something else.
The Toyota dealer should still be able to reflash the ECM to match the VIN.
