Hi all Tested egr with scope at pin 5 and pin 6 took vehicle for test drive pin 5 didnt switch at all just stuck at constant battery voltage about 14v. Pin 6 didnt change either just showed 1.2v didnt move at all. So im thinking the ecu isnt switching the egr valve at all. Does anybody know if a new ecu would come with software on it or does it come blank? Any info would be much appreciated.
