Since the "No Start" thread is lost, I figured I'd start a new one.
The same thing , Lose of Comm, no start, etc, happened to me. I went back to the steps I used with Edit.
1. Get in car(Joel) :wink:
2. Switch on the ignition and turn everything off.
3. Switch off ignition, pull out key and open and close drivers
door. (turns off "power off delay")
4. Connect laptop to OBDII port.
5. Turn on ignition and Program or Copy.
6. * When the "wait 15 sec." notice comes up, don't turn off the ignition.
Wait 10 sec. or until chimes sound 6 times, then turn off ignition. They
usually do, but sometimes they don't stop. Some C5's have chimes.
7. Wait 15 sec., turn on ignition and open V7 scanner.
8. Clear codes.
9. Done.
