I agree with that logic as well. However the two 3 day pass options are for "GM Light Duty Global Diagnostics 2- GDS 2" and "Tech2Win". The first seems to indicate (and what I was told on the phone) that it is only for diagnostic, not programming. The Tech2Win seems to be only if you don't have a Tech2, which I have. Maybe @gmtech16450yz
can clarify that was well. As far as the 09 programing on my BCM. I have read other guys (like @gmtech16450yz
) doing it, either themselves or through the dealer.
. Yes, I read his work on the skyroadster forum. He had good information about the process. I'll reach out to him.
Not to change the subject too much, but has anyone been able to read the SPS programming on their solstice with a Tech2 and TIS2000? I plug everything in, choose SPS, enter my make/year/model, the Tech2 flashes, the dash clicks, DIC lights flash, door chime goes off and then I get presented with my correct VIN. I then select radio (or any option) and hit next, then choose the correct (or any RPO). it does the same dance of flashes clicks lights and bells, but then comes back and says:
The communication count not be established with the vehicle/controller! Please check:
-the connection between Tech2 and vehicle
-that the correct vehicle is identified
-that no communication trouble codes exist on the vehicle
I've read everything I could on the Saab or any forums related to connectivity issues. I've tried multiple supported USB to serial adapters. I even built a physical machine with a real serial port. I've adjusted baud rates, swapped cables for shorter better shielded ones. The Tech2 works fine to read the car. Self check says everything is working, even the rs232 check with loopback is successful. There are no DTC codes on any of the modules on the vehicle. I'm running out of ideas to test. I'm going to try removing the new radio to see if it is causing any issues.
