HELP Mazda 3 ECU
 
Hey I have a 2006 Mazda 3 2.3,
My car is not communicating with any OBDii Readers and i cannot get it smogged or even check the codes. I am sure i have to replace or reset the ECU.
Does anyone know anything about this?

Is there any advice on replacing without taking to a Dealer?

Thanks
