Hi, sometimes the car you examined could have a intermittent code, that was not present at the time you scanned the vehicle.there are scanners however which also gives the pending codes, this are codes that will show up some drive cycles later.
Hi, sorry I misread the question, now I see your bdc is wrong,you must change this by a replacement one that is cloned with your original data ,if you can not do this yourself go to UPFIX https//www.upfix.com>product. Maybe this is helpful.
