    b) Click on: Update Driver Software
    c) Choose: Browser my computer for driver software
    d) Browse to and select folder where you unextracted Driver Pack 6. Make sure 'Include subfolders' is ticked ON.

  1. Your vehicle is notOBD2 compatible.
  2. Random issues that can be fixed with below solutions...

Here are solutions in recommended order:

  1. First check that ELM327 is physically working (not defunct). When you plug in the cable into a USB port, all the lights on ELM327 interface/device should flash. And then it'll return to 1 red light (power).
    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)

    Step 1: Go to Control Panel.

    Windows Vista/7/8/10: Control Panel » System » Device Manager
    Windows XP: Control Panel » System » 'Hardware' tab » Device Manager

    Step 2: Expand 'Ports (COM & LPT)' and 'Other Devices'.
