I was writing to it just like any other day. Yes, full batter on my laptop and car. Editor froze up on erasing, now it won't start, code throwing is U0100 lost communication with ECM. Cannot read from it, only my fuel controller shows up now..... I thought there were failsafes against this type of thing? I'd appreciate some help immediately, as this is my daily driver, and I have been using this thing for almost 2 years now, and never had this happen.
