I bought a clone VCM from China days ago. But when the Ford VCM is connected with the vehicle and laptop, the led light is on. But after 4-5 minutes, all lights are off, and no connection with the laptop, then connect the vehicle and the usb cable, light is on again.
How to do with this kind of problem?
