Can I assume if the radio, steering, etc. etc. is reset that my ECU is reset too?? Even if the radio, ec. reset after maybe disconnecting the battery for 2 min?

 

Well, when I was having problems with my O2 sensors the 1st test I did was disconnecting the battery, because this resets the computer. And yes, as a result all of your settings such as radio, steering wheel, etc is lost. I'm not to sure how long before the computer resets or if it resets instantly upon disconnecting. But, just to be sure I left it disconnected for like 4-5 minutes.
