I have one nagging issue with my clone unit that I would like to solve which is when connecting to a vehicle. Either with or without the candi. With the candi it takes me three power cycles of the tool to see the candi. After that it works as expected. Without the candi it takes several power cycles to connect and then works as expected. On our envoy it triggers an unknown driver and security light on the dash. I have different software and have tried a new cable with identical results. All the self tests I can do pass. I am thinking of playing the amazon return game and picking up a different VCM or OBD connector. Anyone else have an issue like this?
