Default No response from PCM!!! Help

I'm trying to get my tunercat hooked up to the car so I can work on the tune and it keeps giving me the no response from PCM error. I've hooked a scanner up to the car and it works fine, but I can't get tunercat or datamaster to communicate with the car. Need some help. Sent tunercat an email, but no response in 2 days....

Sounds like an issue with the computer or cable you are trying to use to connect to the PCM.

I'm using a AKM cable that I have had for years and I know it works, but I had to by a USB adapter from them to get it to work with USB. I have installed the drivers from the site and I have run the aldl test that they have and all tests pass... This is really frustrating...

Have you tried connecting a battery charger to your battery?

I do that when I use HPTuners.

Feel like an idiot... Got the connection working. I installed the programs on my wife's laptop and still wouldn't connect. Got to looking at the cable, since I had to order the USB adapter from my old serial cable, and I didn't have it just adapted to the cable. This piece was the culprit...
