What is the part number of the CPU? The newest is a 6300JC5. With all surface mount parts I t looks very sparse compared to all the older ones. But regardless, it should be the blue IMS, same as a TAC-20. There is a version that says TIV/TAC-50 but I’ve never had to use it. The way it goes from saying device connected to no device connected back and forth is actually normal, it’s negotiating the baud rate. Sometimes it takes a while to finally connect and get light bulbs. Sometimes it can speed up the process to select the car and hit Control + R to open Remote Fast, close it after it opens and do it again. It’s supposed to kind of “ping” it.
