Title: help with dtc after o2 heater delete Post by: xxx8indxxx on April 29, 2012, 11:20:15 AM can anyone give me some insight on my problems ? i deleted my o2 heaters from my 557p file which i flashed to my 558m ecu the car starts and runs fine and i no longer get a dtc for my o2 heaters but now i get p0601 powertrain internal control module memory checksum error i checksumed the file before i wrote it i used q10 editor and winols and they both said the file was fine ?
could it be caused because i put the 557p file on a 558m ecu the way i understand the ecus are pretty much identical ? i also got a dtc for p0422 powertrain main catalyst efficiency below threshold bank 1 i believe that one can be solved with a o2 spacer! any input would be greatly appreciated Title: Re: help with dtc after o2 heater delete Post by: xxx8indxxx on April 29, 2012, 11:23:24 AM here is the file when i checked its checksum it said it was fine
