Hello I've got a big problem with my HIM device. I've installed Honda Diagnostic software on my laptop and set communication port to com1. Powered HIM and connect it to the laptop but HDS can't communicates with HIM. I've tried to connect while HIM is on power supply and while HIM is connected to the car. While HIM is connected to the car i see yellow and green light flashing for while and then green stays on so I presume communication with the car is ok. Tried to update HIM but no connection. Tried the same procedure on a different laptop and same thing same problem. Bought whole kit (HIM) from OBD2 Diagnostic Tool uk eshop Did anyone had the same problem or heard about it? any solution? Broken HIM unit?
