Same cable too
 
Ok, so next question is where did you get the Serial-Diagnostic cable ?

The USB-Serial looks correct, so suspect the Serial-diagnostic cable or the delay relay is not working. also check that someone hasn't done so wiring mods to the EAS ECU ?

. . . . . . . . and where are you located ?

Try this:
Rich (BB code): 
    

  1. Connect USB-Serial to Laptop
    2. 

  2. Ignition on so EAS ECU is powered, but no need to start car.
    3. 

  3. Connect Diagnostic cable to car, and then connect to USB-Serial
    4. 

  4. You should normally get the Dash beeps because the cable triggers the Delay relay.
    5. 

  5. Then when you try to connect in the software the relay should trigger again & dash should beep.
    6.
 
Worth checking the diagnostic socket on the car isn't green from corrosion but also the connector behind the passenger kick-panel.

Good call on the delay-timer under the passenger seat. Some people replace it with a standard automotive relay to stop it self-levelling after switching off but it also stops diagnostics working.

Hi Sunny
It took me a while to get the software to work but the problem was com ports. After much frustration and help from this forum I discovered that Com port 4 is the one to use. also apparently drivers can cause problems if the right one isn't installed. Mine works every time on Windows 10 now. If you still have problems there's a wealth of info on this forum and someone with more know how will be along.
Good luck.
