Adamw Posted April 6 Report Share Posted April 6 This error just means the ecu was unplugged or powered off while the PC was connected. It most likely means you have a power supply issue so the ecu is not staying powered up while cranking. What car/ecu? Quote Link to comment Share on other sites More sharing options...
