I have identified a potential config setup in the FlashScan firmware that may be responsible for interference on the low speed CAN bus. Please use EFILive_Explorer to program in the attached firmware update into your FlashScan. This update has the same version number as the latest release (V2.07.95) so that you can swap between this firmware and the release firmware. The date on this firmware is Jan 25, 2016 so you can tell it apart from the release firmware.

Paul
