2. Random issues that can be fixed with below solutions...

   Condition of a defunct ELM327 interface: All lights will not initially flash, and only red light will be on.
   
2. Restart computer (while keeping cable connected to laptop). Try again.
   
3. Plug USB into different physical port of your computer. Try again.
   
4. If all above solutions fail, then we will help you (only if you are Total Car Diagnostics customer). Here's all you need to do...
   

   Connect ELM327 USB cable into laptop. (Don't need to plug the other end to car)
