Hi guys,
In followup to one previous post in another thread, I have a question.
Can anyone tell me what a hard reset does, up to my info by undoing the +12volts battery clamp and shorting that cable clamp to ground for some 30 seconds or so.
Does it only reset the ECU and clears any errorcodes and learned settings, or does it also reset other electronic controllers in the car?
Thanks for the info,

Paul
