Trouble connecting with PST2

[getfaster]

I'm having a problem with my laptop based PST2 that I wanted to see if anyone else had ever encountered. I tried a different laptop and different cable on 2 different cars(993) so I'm down to either the KTS card itself or something in the software is amiss. Basically, it will go through the whole scan and then say "System Not Found" after the scan is complete. I know there is some communication because if you leave the car off, the PST2 will prompt "Is the ignition switched on?" and then automatically start the scan when the ignition is switched to the second position. Any thoughts greatly appreciated!

Will it connect to any control modules at all? How about the cable? Original Porsche cable, or Chinese offering?

Won't connect to any module. I'm using 2 different cables I made using your wiring diagram(thank you again!). It had been working and then I did not use it for about a year. Tried it, and now get the "System Not Found" error.

If it has worked in the past, I doubt it is the cable or software. It sounds like one or both of the diagnosis lines aren't connecting.

Have you checked the tiny connector pins in the KTS card? They can be a bit fragile, and can bend, or at worst, break off.

Can you try it on another car?

Thanks for the responses guys. I have tried it on 2 different cars and checked the connectors on the KTS card. I'm pretty short on options at this point so I think I will make up a shorter cable (current cables are 3 meters) to see if it might be related to signal loss or interference. I do have a ferrite suppressor at the KTS end of the cable but who knows.
